FOREWORD & COLOFON I GARDEN CULTURE
FOREWORD
GARDEN CULTURE GOES DOWN UNDER
Here at the Garden Culture HQ we opened a bottle of nice
Champagne when we got the news about distribution in Aus-
tralia. We’re very proud and honored that our Australian and
New Zealand distributors loved our magazine so much that
they decided they wanted to pick it up for their customers.
Let me start off with what Garden Culture Magazine is and how we started. Back in 2011 we came up with an idea to make a maga-zine tailored to Urban Gardening. Our aim was to go beyond the gardening magazines currently out there which were made for a bit of an older audience than us. We love to grow in and around our homes and we sadly don’t have acres of land to do that. Because we all live in cities we started growing in our house, rooftops or our small balcony.
The current magazines out there just weren’t cutting it for us. We want cool stuff, techy gear and the latest kits around. Looking in the marketplace at that time there was nothing which had that so we decided to launch Garden Culture magazine in our home market, the Dutch market. From there it’s been a rollercoaster ride where we expanded faster than we ever imagined.
We hope you will have a lot of fun reading the magazine and learn a thing or two. If you have input, feedback or you like to write for us get in touch please. We’re active on Facebook or you can simple mail us at [email protected]. Alternative for more reading or a subscription on the magazine check out our website at www.gardenculture.net

NF Zyme’s unique formula has the ability to opti-
mise all modes of growth or flowering by helping
your plant to control cell division and optimise root
growth. It contains amino acids and micro nutrients
that assist nutrient uptake, growth, root formation
and increase the plant’s metabolic rate. NF Zyme
aids in photosynthesis and food formation, which is
caused by the regulation of stomata openings. This
increases the carbon dioxide uptake of plants. The
natural chelation process combined with the micro-
nutrients also makes presently unavailable nutrients
and minerals to become plant absorbable in all stages
of plant development.

Plants, like all living creatures, need energy to survive.
Animals get this energy feeding on plants or other crea-
tures. But plants don’t feed on other creatures. Plants
store the energy they need by combining elements from
soil and air using sunlight to power the reactions. A rad-
ically different survival strategy compared to animals.
This method of energy harvesting is commonly known
as photosynthesis.
In essence, photosynthesis isn’t all that complicated,
however when inspected more closely, one will find out
that it is a cascade of many chemical reactions. To make
this a little less complicated photosynthesis can be split
up in two parts; ‘Light reactions’ and ‘light-independent
reactions’.
LIGHT REACTIONSLight reactions are the first part of photosynthesis.
These reactions require light in order to work. When a
Carbon dioxide in plants
photon from the sun or a grow light strikes the photo-
receptive pigment called chlorophyll, water is split into
two oxygen molecules and one positively charged hy-
drogen atom, also known as a proton. These protons in
turn are used by the plant in the light-independent reac-
tions. But most importantly, the plant uses the energy
of the protons to convert ADP (adenine di-phosphate)
into ATP (adenine tri-phosphate) by adding a phospho-
rous group. This is how plants store energy in a usable
way, essential in many vital processes. The ATP can be
used as a means to transport chemical energy, because
when it is converted back into ADP energy is released.
The molecule can then be recycled into ATP again. The
resources the plant has to invest in order to perform
these reactions is always the same. However, not all
wavelengths of light are equally effective at stimulating
chlorophyll, and some wavelengths transfer no energy
at all. In general plants are most efficient in the blue
and red ranges of the spectrum. Green light is poorly
There are a couple of things that plants can’t live without. Carbon dioxide is one of these substances.
It’s a gas, commonly found in the atmosphere. Although it isn’t as common as oxygen and nitrogen,
which make up around 99% of the atmosphere’s volume, carbon dioxide is still relatively common.
Over the past decade or so, carbon dioxide has been in the news frequently and has suffered from a
bad reputation for being a greenhouse gas that contributes to global climate change. This conclusion
has some merit since it is often added to greenhouses to boost plant production. This article is a short
introduction into the how and why of carbon dioxide addition in greenhouses.
An introduction:

CARBON DIOXIDE I GARDEN CULTUREBY JEROEN

Carbon dioxide in plants
absorbed by chlorophyll. Instead it is reflected into our
eyes, which makes plants look green to us.
LIGHT- INDEPENDENT REACTIONSThe dark reactions then follow up on the light reac-
tions. This is where carbon dioxide comes into play.
The proteins that were created during the light reac-
tions are now used to fixate carbon. Carbon fixation is
performed by plants using a process called the ‘Calvin
Cycle’. A number of different chemicals, including the
protons, carbon dioxide and ATP go into the reaction
and in the end yield a simple sugar which in turn can be
used by the plant to produce a number of other things
including larger sugars and starches. Contrary to the
light reactions, these light-independent reactions cost
the plant energy.
Like with any chemical reaction, or biochemical reaction
for that matter, a plant has to have all the ingredients
to perform photosynthesis. One of these ingredients is
going to be the limiting factor to the reaction. One can
understand that if enough water and light are available
to plants, CO2 could become a limiting factor. This can
certainly be the case since CO2 is present in the atmo-
sphere at levels around 360ppm (parts per million). This

is where it starts to get more difficult. Most
plants benefit from CO2 addition because the
enzyme that transports CO2 inside the plant
can get distracted. You see, this enzyme can
also bond with oxygen, transporting less carbon
dioxide into the plant. This makes the process rather
inefficient, as oxygen is available at higher concentrations in
the atmosphere. These plants, called C3 plants, benefit greatly
from added carbon dioxide.
CARBON DIOXIDE PRODUCTION In a greenhouse there are a number of ways to produce
carbon dioxide. Piles of composting materials can be used
to produce carbon dioxide in a greenhouse however this
has drawbacks when it comes to pest control. A more
modern way to increase the CO2 concentration is by
burning propane, or some other gas. Gas burners can be
linked to controllers and sensors that monitor and adjust
the burn rate according to the need of the plants. This is
the most common method of CO2 production and, besides
recycling CO2 from another source, the least costly. Using
pressurized cylinders is too expensive and cumbersome.
There are some drawbacks to burning fossil fuels to pro-
duce CO2. With improper combustion there is a possibil-
ity carbon monoxide is formed instead of carbon dioxide.
This is a poisonous and potentially deadly gas, odorless and
definitely something to watch out for.
Carbon dioxide is something every plant needs and is pres-
ent in the atmosphere in small concentrations. In situations
where it’s preferable to grow crops intensively, CO2 is a
welcome addition to boost plant growth. The addition of
CO2 increases the rate of photosynthesis that is possible
in nearly all plants but other factors change too. In order
to get the maximum efficiency out of the added CO2, tem-
perature and humidity have to be pushed to an extreme. In
reaction to this the speed of every process in the garden
increases. This does sound rather easy, however a more
extreme climate also increases the chances of pests and
other problems one would want to avoid in the crops. Car-
bon dioxide addition requires a lot of attention to do well,
but it can be a valuable tool in increasing yields. It is the
next step for gardeners who have mastered their indoor
growing environment. 3
WHEN ENOUGH LIGHT AND WATER ARE AVAILABLE,
CO2 BECOMES THE LIMITING FACTOR

What could this possibly have to do with
gardening and the success or failure of
your garden? When you need a new cell-
phone do you head down to your local
electronics supplier and buy a bunch of
microprocessors and resistors and head
home to construct your new phone like
the mad doctor did with Frankenstein on
that stormy night? Of course not. You
head over to the cell phone store or dial
it up online and click buy, pay for it and
then start texting your friends to boast of your new pur-
chase. You don’t know how to wire or build a cell phone and
for most of you new growers, your garden is no different.
You’ve spent hours researching online, head out to your lo-
cal Hydro store or order online and acquire your new grow
equipment, head home and start to assemble the puzzle of
pots, trays, tubing, pumps and then muster up the courage
to mix up your first batch of feed solution. You’ve done all
this with no experience growing a plant and no knowledge
of how it should all work, why?
Your new garden is a like a new baby. Would you bring
your new bundle of joy home and sit him in front of a giant
19
NY prime steak and expect him to
eat? Absolutely not. You’ve got to
take it slow, learn to walk before
you run and K.I.S.S.
A new grower should start simple
with one ore two lights, minimal
number of plants, pots with soil
and a very basic nutrient feed
solution. Hand water these new
born babies and spend time in
your garden EVERY DAY!
Take the time to study your plants. Study their reactions, what
makes them happy and of course, what makes them sad. As
you get through your fist crop or two, you will begin to realize
that there is more to indoor gardening then meets the eye.
Only then can you begin to make the educated decisions need-
ed to outfit your garden, and progress into a more advanced
and automated grow system.
The simpler your first garden is, the more SUCCESSFUL
you will be! There will come a time for the latest technol-
ogy and all the bells and whistles, just think of the evolution of
spy planes. Clarence Johnson said it right when he coined the
phrase - Keep It Simple, Stupid! 3
K.I.S.S. I GARDEN CULTURE
gardenculture.net
Keep It Simple StupidHistorical concepts for a Bumper Crop
YOUR NEW GARDEN IS A LIKE A TINY BABY. WOULD YOU BRING YOUR NEW BUNDLE OF JOY HOME, SIT HIM IN FRONT OF A GIANT NY PRIME STEAK AND EXPECT
HIM TO EAT?
The acronym was coined by Clarence Johnson, lead
engineer at the Lockheed Skunk Works (creators of
the Lockheed U-2 and SR-71 Blackbird spy planes,
among many others). The principle is best exemplified
by the story of Johnson handing a team of design engi-
neers a handful of tools, with the challenge that the jet
aircraft they were designing must be repairable by an
average mechanic in the field under combat conditions
with only these tools. Hence, the ‘stupid’ refers to the
relationship between the way things break and the so-
phistication available to fix them.
The principle most likely finds its origins in similar concepts such as:
• Albert Einstein’s maxim that “everything
should be made as simple as possible, but no
simpler”.
• Leonardo da Vinci’s “Simplicity is the ultimate
sophistication”.
• Mies Van Der Rohe’s “Less is more”.
• Antoine de Saint Exupéry’s “It seems that
perfection is reached not when there is noth-
ing left to add, but when there is nothing left
to take away”.

light cycle. However, different plants and different stages of
growth require varied humidity. So, be sure to learn what the
best RH levels are for your crop at each stage, as some plants
will prefer a drier climate and others need high humidity.
A seed sprouts and rapidly develops a good foliage
canopy and abundant roots in the cooler, shorter days
of late spring and early summer when high moisture
is present. As temperatures climb and day length
increases, high outdoor humidity can be a bad, even ugly
thing. The purpose of an indoor garden environment
is to give plants optimal conditions through all stages
to harvest. Coaxing them to produce that bumper
crop you want includes controlling relative humidity.
This is why many indoor hydroponic growers have separate
vegetation and flowering to fruiting grow chambers. It is
also why some plants are good indoor companions and
others aren’t.
gardenculture.net
Moderation applies to all life formsAs a grower you must regulate the environment and
climate for your crop. Especially if you don’t want
them to go on strike, get lazy and refuse to perform.
It is best to take your role as climate creator seriously.
Understanding what relative humidity (RH) is and how it
affects the plants in your indoor garden is an important
part of a healthy crop and an abundant harvest. The
wrong humidity level can present you with a number
of issues that vary by crop type. At early growth stages
low humidity can cause your crop to go on a binge eating
spree while profusely perspiring. The result is they burn
to a crisp from the loss of water that maintains nutrient
levels in their systems. Obviously, this is bad, at best.
In an attempt to improve dry conditions the plants will
absorb more nutrient solution than in proper humidity.
At the same time they rapidly shed water through the
cell pores on the underside of the leaves known as the
stomata. What is the result of this undesirable situation?
Even a weaker solution will lead to nutrient burn.
What’s the right RH Level?It would be great if it were that easy, to have one metric to
aim for here. You have an average humidity level of 50-75%
for best results with dark cycle RH levels being higher than
BY TAMMY CLAYTON
Everything and everyone is affected by humidity, or
the lack of it. Plants are more sensitive to humidity
levels and its variations than humans or animals.
We manage to live through the discomfort. Plants
manage humid conditions too, but the effect
can be undesirable. Improper humidity levels
affect plant functions and can cause irreparable
damage to roots, stem, foliage, flower and fruit.
The worst case scenario is pretty ugly. You could
watch the death dance in horror, not knowing
how to stop the process.

HUMIDITY I GARDEN CULTURE
VARYING RH LEVELS NEEDED FOR DIFFERENT GROWTH STAGES GERMINATION & PROPAGATION STAGE: Maintain rooting
cuttings or germinating seedlings humidity at above 80%. A
propagator makes controlling RH more manageable and allows
your new crop to concentrate energy on producing the roots.
Some crops can be successfully propagated in your grow tent
using a humidifier with a humidistat.
YOUNG PLANTS: Between minimal foliage to breathe
out water (transpiration) at night and the hot lights, many
growers experience problems keeping the RH levels
high enough to produce strong growth and plant vigor.
In 0,6 m2 of grow space, using two 600 watt lights, you’ll
generally find 35-50% RH and a temperature of 22-28 C.
As described earlier, low humidity will make the plants work
overtime at creating humidity. You don’t want the RH to drop
below 40%. This brings issues with nutrient overload and other
related problems. Your target RH level at this stage of growth
should be 60-70% for faster root growth, leaf development
and more compact plants.
VEGETATIVE STAGE: These larger immature plants have more
shoots and leaves. They will take up increasing amounts of
nutrient and emit more water vapor as they increase in size.
At this stage you want to ensure the RH levels don’t climb too
high. This danger increases as plants thicken.
FLOWERING & FRUITING STAGE: The ideal RH range here
is 50-60% during daylight cycle and 60-70% during the dark
cycle. Keep on top of RH control, as both fruit and flower are
easily damaged by fungal disease with soaring humidity. High
humidity related fungal problems can ruin many kinds of fruit,
vegetable and flower crops.
Increasing the RHMisters and humidifiers are used to increase RH levels. The
more water vapor being emitted by your plants into the
grow room environment, the less the humidifier or mister
needs to be run. For plants that need tight humidity control a
humidification system with HR-HRSA humidistat is best.
Decreasing the RHVentilation drops your grow room RH level. Depending on
your crop and grow space situation, at times an extraction
fan with a variable speed control is all that is needed. High
RH levels can also be corrected by with a dehumidifier.
Great care is needed to not remove too much moisture,
creating a dry environment. This can cause some plants to
emit water through leaf tips, allowing it to collect on foliage
and promote disease development. Ultra-sensitive plants
may do best with a humidification system that precisely
delivers both humidifying and extraction functions in one.
Measuring Your Humidity LevelsTo stay on top of the RH level at all times, you
need an instrument known as a hygrometer
to give you humidity readings. Be sure
to select one that is water resistant and
designed for the demands of hydroponics.
These will give you the connected accurate
temperature and humidity measures.
RH Changes with Temperature VariationIn your grow space, the relative air humidity is influenced
by temperature. High RH disrupts a plant’s ability to
get rid of excess water. Low RH makes the plant emit
too much water and can cause the intake of CO2 to
stagnate, leading to impaired growth. Nutrient up-
take rate increases with dry air, and for about every 5.5
C temperature increase the amount up-take doubles.
Both of these fluctuations greatly affect your crop.
Ideally, you want your grow room to have a lower humidity
during the day cycle than the night cycle. During the
darkness hours in the growing space, many assume that
without the heat of grow lamps, the humidity will drop.
This assumption could get ugly. In darkness, plants breathe
out water, increasing the need for air flow and ventilation.
Ignoring this puts your entire crop at risk for pest and
disease outbreaks, among other health issues. 3

If it’s all in the ‘too hard basket’,
then don’t despair! Start with these
easy-to-grow plants and get at least
some food on the table without the
need for garden tools. These ideas
only require minimal time and a few
basic supplies to start saving money
and improving your health.
The easiest plants to grow are those
that don’t require gardening skills and only minimum
time input, materials and space. Herbs that grow in a
glass of water on a well-lit bench or window sill are an
ideal choice.
If you buy spring onions (or you may call them shallots),
save your money and regrow them from now on. With a
sharp knife, cut your spring onions about 5cm above the
root. Use the leaves in your meals but add the stem base
and roots to a small glass with 1-2cm of clean water.
Change the water daily to prevent bacteria growing,
then watch new green leaves grow. Snip with scissors
for tasty, free meal additions!
25
Instead of buying bunches of fresh herbs, propagating
your own will save you money and reduce wastage.
For example, add leftover stems of mint, lemon balm,
rosemary or basil (with lower leaves removed) to a glass
of water. Change water daily. Roots should develop in 2
weeks or less and provide free plants to transplant into
a pot for an easy herb garden.
Mint and lemon balm are both shade lovers. Lemon

and relieve morning sickness if drunk with lemon first
thing in the morning. Mint has antiseptic, antiviral and
anaesthetic properties and chewing a few leaves can
help relieve sore throats, colds, coughs, and headaches.
These are great medicinal and culinary herbs to have on
hand. Why waste time going to the chemist when you
can have healthy alternatives right at home?
Aloe vera is another hardy home pharmacy plant that
thrives on neglect, grows well in a sunny spot indoors
or outside in a shallow pot, with well-drained potting
mix and an occasional watering. Break off a leaf and
scrape the gel inside as an aftershave balm or skin
moisturiser, to heal burns, soothe stings, bites, rashes
and cuts. Keep cut leaves wrapped in the fridge.
For delicious salad or smoothie ingredients packed with
digestive enzymes, microgreens are the perfect solution.
These baby greens are healthy ‘fast food’ you can grow
from ‘seed to feed’ in just 1-3 weeks depending on seed
variety. Add about 2-3cm of moistened seed raising mix
to a container with drainage holes (reusing a plastic
strawberry punnet is ideal). Adding a sprinkle of rock
minerals will boost nutrient value and flavour. Evenly
spread a tea spoonful or so of organic herb or vegetable
seeds over the mix. Sprinkle a little extra seed raising
mix to just cover seeds, mist with water in a spray
bottle and cover with a clear lid. Place in a well-lit area
and mist daily to keep seeds moist until they sprout and
grow. Snip with scissors just before adding to meals.3

growth truly a sign of thriving plants? Or is it obesity?
Plant obesity and deficiency are what attract and create pests
and disease, not unlike a human on a bad diet. Truthfully, the
average gardener believes that pests and disease are bad luck.
Due to this lack of perspective, most attempt to kill their
problems away instead of addressing the roots of the issue.
It’s a vicious cycle. Most of the time we are creating our own
problems. What should we expect when we use artificial
fertilizers and toxic pesticides
to grow living plants?
Even hydroponic fertilizers
contain no more than 17
elements, or only what a plant
has to have. Most plants can use upwards of 30-40 elements
directly or indirectly, some more than that, but microbes use
every single one of them to work their magic. Growing a
garden without all of the elements in play is like hiring someone
to build a house and giving them half the tools.
Consider using rock dusts or sea-mineral based products to
increase elemental diversity in the garden. Not only will you
increase yields, but you will build the innate capacity in plants
and microbes to fend for themselves. After all, why would
Mother Nature make an element not needed in the garden?
The same is true for microbes. The greater the mineral and
biological diversity in the garden, the more strength and
The quality of food cannot truly be evaluated until it is eaten,
but we cannot taste all the things that are harmful to us and
artificial flavoring has resulted in us forgetting how food is
supposed to taste anyway. We are farther away from the farm
and our food than at any point in human history. Many farmers
don’t eat what they grow. Agriculture has collectively become
a race to the bottom line where the food that is produced is
designed to sit on a shelf, not nourish our bodies.
People are clamoring for real
food. Community Supported
Agriculture (CSA) programs
and farmer’s markets are
booming, and record numbers
of people are planting gardens for the first time in their lives.
The future of food is to know your own personal agriculture.
What better way can you do this than by growing your own?
Growing the best garden of your life is done through the
marriage of quality gardening products and techniques, and
a proper perspective towards the natural world. One of the
primary ideas to keep in mind when growing a garden is diversity.
Using cheap budget fertilizers that have 6-7 elements in them
is the equivalent of fast food for plants. Sure, the plethora of
artificial gardening products available on the market stimulates
plant growth and often creates higher yields initially, but is the
Check this out. Some of the most important things regarding the evaluation of a garden and the food
it produces cannot be observed. The majority of people don’t realize that the soil is alive and teeming
with beneficial microbes, because they can’t see them.
Think of it this way...
don’t feed your plants,
feed your soil
THE INVISIBLE GARDEN
29
balance you bring to the ecosystem. Think of it in this way…
don’t feed your plants, feed your soil. Microbes have been
helping and protecting plants since the beginning of time and
they are not going to stop anytime soon. In fact, over half of the
carbohydrates a plant makes for itself through photosynthesis
are exuded through roots to attract beneficial microbes.
A great way to enhance the
beneficial microbes in your garden
is by brewing compost tea. This
involves using aeration to grow
microbes from compost in the
presence of biological food sources
and mineral catalysts. Compost tea can and should be used
in every garden, including hydroponics, as it is a great way to
make sure you are growing thriving plants. After all, people
don’t make plant food, microbes do.
In addition to the friendly microbes and fungi there are
other invisible forces active in your garden that affect the
growth of all plants. For those feeling truly experimental,
consider planting by celestial rhythms. It is well known that
lunar cycles affect plant growth. There are many “plant
by the moon” calendars online. There is even a method of
gardening called Biodynamics that includes a broader range
of celestial phenomenon and recommended planting days,
flower days, root days, etc. It’s fascinating. Biodynamics is
used extensively in other countries like Australia that have
poor soil, and is also used widely in viticulture. Not many
farmers pay closer attention to their crops than those
growing grapes for wine. The idea of working with natural
energies in the garden is a foreign concept to most, but life
is defined by energy on every level of its existence. The
29
articulation and use of subtle energies is the new frontier
of farming and gardening. The philosophy that utilizes the
subtle forces of nature in the garden is called Bioenergetics
and seeks physical, mineral, biological and energetic
balance. This is the sweet spot that allows plants to truly
thrive and become vitamins for life.
Beyond all the products and techniques, the most powerful
tool we have in the garden is our perspective. What we
think, we grow. Sure, we don’t have to grow this way, but the
question is…what are we missing?
You will find your own way into testing and verifying these
ideas, but hopefully some seeds of experimentation have been
planted. Now get growing! 3

MODERN SLAVERY I GARDEN CULTURE
BORN TO WORK
If you’ve got kids, you’ll probably hear these words on a daily
basis. It’s not that “fairness” is a childish concept; it’s more
that the idea establishes itself so early that it runs to the
very foundations of our collective consciousness and
remains there for the rest of our lives. Indeed,
as we grow older many of us hold on to the
belief that we possess an intrinsic ability to
recognize when a situation is equitable.
BY EVEREST FERNANDEZ
In reality though, this world of fairness and equity is dependent
on one thing; our brains and our willingness to exercise them.
For instance, if I declare myself the “leader” of a remote
Polynesian island and convince its inhabitants that I am their
deity incarnate whom they must please with daily offerings of
their youngest, fairest maidens, while the men labor all day in
the fields and copper mines so that I, the Great Lord Everest,
may be glorified and gracious in sparing them my wrath. The
islanders, if taken in by this almighty bounder, may conclude
that their situation is quite fair and just. It’s a square deal: they
offer up their bodies for sexual and agricultural services in
exchange for my “wrath” being spared. On the other hand,
as an outside observer, you might conclude that they’re being
exploited for their ignorance.
If that example seems a little weak then picture another
scenario, a little closer to home perhaps. Let’s say you and
I are neighbors, living out in the lesser-trodden parts of the
Humboldt countryside in Northern California. Add to this
blissful scene a single cow grazing on my ample pastureland.
And you, perhaps not enjoying so grand an estate, are content
to take care of a small brood of chickens. Now, I’m not
suggesting that this situation is unfair. I may have chosen to
work longer and harder for my larger slice of this fine Earth.
But, in the spirit of community, we choose to share stuff. I
like eggs and you like milk, so we agree to make a swap
each morning: a pint of my (or Daisy’s) milk for two of your
(chickens’) eggs. What could be simpler than this direct barter?
Notwithstanding our animals’ rights or wrongs, so long as we
humans establish mutual consent, we can share and enjoy our
collective resources and life seems a whole lot more sunny-
side-up for the both of us.
However, here’s where the plot begins to curdle. What if I
awoke one morning intent on pursuing a more favorable
deal for myself—say, just half a pint of milk in exchange for
your two eggs? What then? A civil discussion over the garden
fence, perhaps, with the hope of modifying our consensual
agreement? Of course, you might inform me that I can “keep
my milk” or other choice words to that effect. So what if I
choose to avoid confrontation by secretly diluting your “pint of
milk” with rainwater? Just a few drops at first so as not to raise
your suspicions, yet slowly but surely, over the course of a year
or so, I diluted the milk to the point where it’s actually fifty
percent water! I’m patting myself on the back for executing
this change so gradually, while all along you are none the wiser!
I laugh with contempt at your hapless children, for watery
milk is all they’ve ever known! Moooooohahahahaha! Another
generation of suckers is born!
Perhaps I’m guilty of overly-indulging this example. Maybe I’m
assuming a little too much naiveté on your part? Surely you’d detect
that something was up with the milk, wouldn’t you? Nevertheless,
emboldened by your seemingly boundless gullibility, I decide to
take my scam to a whole new level. Instead of giving you watered-
down milk, one day I turn up at the garden fence with something
entirely new. It’s a piece of paper. I call it a “milk certificate.”
“You can redeem this for ‘real milk’ anytime! (Wink, wink)” I
assure you, “What’s more, you can use these milk certificates as
payment in trades with other vendors. It’s so convenient for you!
And, best of all, you don’t have to keep them in the refrigerator!”
Okay, by now you’ve guessed it; we’re talking about money,
not milk. But this milky analogy needs a few modifications
before it even comes close to accurately reflecting our

services. (The Spanish discovered
this when they returned from the
Americas with boats laden with
gold. They thought they were
going to be incredibly wealthy, but
the amount of goods and services
available back home had not really
changed. Result? Prices simply
went up!) The real privilege of the
super-rich is their priority lane access to this newly created
money. In essence, it’s not so much the quantity of money
they have, but the fact that they get to spend it into circulation
first, before the rest of us cotton on to the fact that it’s been
watered down. By the time these dilute dollars finally meander
to you and me, it’s little more than cloudy water, or symbolic
cloudy water, or … confused? Good. Now get back to work.
Perhaps we need to ask ourselves this very simple question:
what is money? Don’t shy away from it—no need to
overcomplicate it either. You don’t want to spend your
life chasing an enigma now do you? Don’t leave this to the
“experts”—the people whose career depends on maintaining
their intellectual propriety with confusion and obfuscation.
You shouldn’t make the mistake of thinking that money is
intrinsically a bad or evil thing either. At the very least concede
that it’s very useful stuff, helping us to transcend the limitations
of direct barter. Problems really occur when we seek money
as if it were the true wealth in and of itself, rather than merely
a symbolic means of exchange.
So what are we to do? Should we join some protest movement
waving “End the Fed” banners? Should we petition our
governments for greater freedoms, or is that, as the monetary
prophet E.C. Reigel wrote over fifty years ago, just an absurd
act of deference, “wholly lacking the spirit of a freeman.” In
short, are we going to take responsibility for the mess we’re
in, or are we going to let “the economists” sort it all out for us?
All facetiousness aside for a moment, one by one, we are
indeed waking up to the fact that something is very wrong.
Looking at the world with the eyes of our ancients we realize a
fundamental truth—our monetary system has been corrupted
to one where national sovereignty is a joke on a naive
populous. We are collectively enslaved to ‘unelected’ central
banks through usurious and fraudulent money systems, an
eternally un-payable “debt,” created out of nothing but our
promise to repay. It is a deeply absurd and untenable situation
present predicament of economic
slavery. You see, up until 1971, a
dollar was redeemable for gold.
Gold was chosen because it was
viewed as universally valuable.
People, knowingly or unknowingly,
accepted dollar bills in exchange
for real goods or services backed
by a belief that these little pieces of
paper would be later accepted by others—and an assurance
that they were also convertible into physical gold at any
time—well, during banking hours at least.
However, since the dollar was decoupled from the gold
standard, it has lost around 90% of its purchasing power.
Thinking back to our milk for eggs exchange, you might be
tempted to picture a bottle of slightly cloudy water being
handed to you over the garden fence, or a fistful of worthless
“milk certificates.” But think again. For, if I am assuming the
role of the banker in this scenario, I’m actually asking you to
borrow some pieces of paper (with no mention of milk, eggs,
sex, honey or anything else that’s tangible) and pay interest for
the privilege! All these pieces of paper represent is your debt
to me—a debt that I have created out of nothing, meanwhile
you pledge to forfeit your house if you don’t keep up the
repayments! Perhaps the Polynesian islander’s example wasn’t
so far out of whack?
With the woe-is-us-machine we know and love as the Internet
now running on all twelve-cylinders, it’s easy to blame Wall
Street greed, the Illuminati, the neoconservatives, the royal
family—anybody, in fact, but ourselves for the mess we’re
in. But the inescapable fact is the only thing that holds up
our monetary system is our persistent belief in it and our
unwillingness to embrace viable alternatives. Our problem is
one of philosophy, not politics. How have so many of us been
hoodwinked into accepting such an absurd tautology: a dollar
is worth another dollar—what sort of insidious, circular,
recursive symbolism is this? But then, take these dollars away
and how are you going to pay for your groceries?
You really don’t need a PhD in economics (or any other
pseudo-science for that matter) to understand that as more
make-believe money is pumped into the financial system,
the purchasing power of each dollar is diluted, just like the
nourishment of our watery milk. This is inevitable so long as an
inflated money supply chases the same amount of goods and

FRAUDULENT MONEY SYSTEMS
for any person to endure. Yet
the mainstream media persist in
echoing the bankers’ threats of the
sky falling down and untold misery if
we don’t put up with the status quo.
Heaven forbid if enough people
discover the truth—that we don’t
actually need banks at all in order to
issue currency and trade with each
other, on a personal, corporate or
even national level.
The Internet has helped us share
our ideas, but its real power is in the
creation of a common monetary
language. Forget about “internet-
banking”—that’s just a sideshow.
Imagine a new form of money,
issued by the producers of this world. By producers I mean
the corporations that generate our electricity, or make our
computers, or grow the tomatoes. Imagine money backed, not
by debt, or by gold (or tungsten) but by … wait for it … real
stuff. Cars, beef burgers, Thai massages, goods and services
that we use every day. Sounds unbelievable? Well, so did the
concept of a spherical earth to most people a few thousand
years ago. It’s time to unplug from the Matrix.
At the center of it all is a global scale of value. What’s that?
Well, think of an inch. Or, if you prefer, think of a centimeter,
a foot, a mile, or a furlong. Where would we be without these
universal units of length? Now imagine if we created the same
thing, but for value. Of course, we’ve been conditioned into
mistaking our monetary units as our value units. When we
talk about the value of things we invariably think in terms
of dollars, or pounds, or yen, don’t we? This beautiful, shiny
phone costs $799. This car costs $25,000. This house is
valued at $500,000. We need to stop thinking like this.
This ignorance is at the kernel of our enslavement to the
bankers. We are guzzling watery milk without so much of
a whimper of complaint. Now it’s time for a good burping.
Unlike an inch or a centimeter, the dimensions of a dollar
keep changing. We call this “inflation.” But how then can we
measure “value” using these shape-shifting units of exchange?
It’s almost as if we are confusing the item being measured with
the ruler it’s being measured on. Are you beginning to see the
magician’s sleight of hand? Money has no real value.
Crucially, take note that a global
scale of value is not the same thing
as a global currency. Moreover,
a global scale of value would
give birth to thousands, maybe
millions of different currencies,
not just one—but they would all
be measured on the same scale,
and all of them backed by goods
and services in common demand.
The ratio of credit to demand
(i.e. offers to buy vs. offers to sell
a company’s credit token) can be
instantly evaluated, thanks to the
Internet, meaning the actual value
of the credits in circulation can
adjust in real time. The idea of
money as fluid and self-correcting,
does not reward greed and is based on real goods and services.
It may be a little tricky to grasp at first but really we’re only
describing a world where the monopoly over the issuance of
credit, currently enjoyed by banks, has been removed. If this
sounds crazy then remember, so did the idea that the world
was a sphere and that there were potentially people living
“upside-down.”
Ultimately, the real treasure of this planet is you and I. It’s time
for the credit commons to be restored to the people instead
of being monopolized by bankers who create nothing. Until
enough of us wake up to their false pretentions towards deity,
docile and malleable human beings will remain the ultimate
resource to be controlled, manipulated and exploited. 3

AQUAPONICS I GARDEN CULTURE
gardenculture.net
How does it work? Aquaponics is, at its most
basic level, the marriage of
aquaculture (raising fish) and hydroponics
(growing plants in water and without soil) together in one integrated
system. The fish waste provides organic food for the growing plants
and the plants naturally filter the water in which the fish live. The
third and fourth critical, yet invisible actors in the play are the
beneficial bacteria and composting red worms. Think of them as
the Conversion Team. The beneficial bacteria exist on every moist
surface of an aquaponic system. They convert the ammonia from the
fish waste that is toxic to the fish and useless to the plants, first into
nitrites and then into nitrates. The nitrates are relatively harmless
to the fish and most importantly, they make terrific plant food. At
the same time, the worms convert the solid waste and decaying
plant matter in your aquaponic system into vermicompost.

“Farm and ranch lands cover nearly 40
percent of Earth’s land area”
While aquaponic techniques can’t address this shocking
statistic per se, they can certainly mitigate the impact. Be-
cause aquaponics is a soil-less growing technique, plants and
fish can be grown anywhere, including on land that is consid-
ered unfertile (too sandy, too rocky, too toxic) and even in
old warehouse buildings and unused parking lots.
“Agriculture consumes nearly three quar-
ters of the earth’s available water”
Because aquaponics is a recirculating system, the only
water “lost” is either held in the plants, transpires through
their leaves, or evaporates from the top of the fish tank.
Aquaponics is generally thought to use less than a tenth of
the water of traditional agriculture for the same crop output.
“Agricultural activities such as clearing land,
growing rice, raising cattle and overusing fer-
tilizers make up 35 % of the single largest con-
tributor of greenhouse gases to the atmosphere”
None of these practices have any place in aquaponic growing.

“About 40% of all crops the planet produc-
es are used to feed animals.”
Fish are the single most efficient converter of feed
to flesh of any edible animal. One and a half pounds
of feed will bring to harvest one pound of edible, om-
nivorous fish fillets. It takes eight pounds of feed to
produce the same single pound of beef fillets.
While not mentioned in the article, we should
also add “consuming petroleum” to this list.
Between oil-based fertilizers, oil-fueled farming
machinery, and long distances between farm and table,
modern food is “dripping” with oil. Aquaponic systems
on the other hand, have no oil-based inputs and are run
entirely on a small amount of electricity. This electric-
ity can be created through currently available renew-
able energy methods.
Nothing in the Nature Magazine report was
surprising for anyone engaged in the worldwide
‘future of food’ dialog. However, what was
striking was that aquaponics (growing fish
and plants together in a recirculating, soil-
less system) was not included among the set
of proposed solutions. Aquaponics is a food-
growing approach that addresses the harmful
practices cited in the study and simultaneously
realizes the potential for increased food
production envisioned by the researchers.
Widespread adaptation of aquaponics
could both alleviate all of the environmental
destruction cited by the researchers and provide the vehicle for increased sustainability and productivity.
First, the environmental problems with current agricultural practices were outlined in the report as follows.

Aquaponics is not the answer to all of our future
food supply and environmental issues. Grains and
root crops, for example, will probably always be most
efficiently grown in the soil. But for above ground,
vegetative crops and fish protein, there simply isn’t a
better growing technique on, and for, the planet. 3

The researchers then recommended five changes to
current practices that they believe will not only help
to solve the issues stated above, but will also extend
our ability to feed the burgeoning world’s population.
All but one can be implemented through aquaponic
growing techniques.
“Halt farmland expansion.”
As explained above, because aquaponics is a soil-
less growing system that can be set up anywhere, it is
perfectly suited to address this goal.
“Close yield gaps. Many parts of Africa,
Latin America and Eastern Europe have
substantial “yield gaps”- where farmland is
not living up to its potential for producing crops.
Closing these gaps through improved use of
existing crop varieties, better management and
improved genetics could increase current food
production nearly 60 percent.”
Because of the consistent and ideal mix of water, oxygen
and fertilizer that an aquaponics system provides, plants
grow significantly faster in an aquaponics system than
they do in soil. In addition, plants can be placed closer
together in aquaponics systems because they are not
competing for those resources in their root zone. This
is an answer to the search for “better management”
techniques that the researchers are seeking.
“Use inputs more strategically. Current
use of water, nutrients and agriculture
chemicals suffer from what the research
team calls “Goldilocks’ Problem”: too much
in some places, too little in others, rarely just
right. Strategic reallocation could substantially
boost the benefit we get from precious inputs.”
Since aquaponic systems use comparatively so little
water, inherently produce their own nutrients, and use
no agricultural chemicals, the problem of redistribution
becomes a non-issue.
“Shift diets. Growing animal feed or biofuels
on top croplands, no matter how efficiently,
is a drain on human food supply. Dedicating
croplands to direct human food production
could boost calories produced per person by
nearly 50 percent.”
Fish protein is not only heart-healthy but, as
mentioned above; it is the most efficient converter
of plant protein to animal protein known to man.
“Reduce waste. One-third of the food farms
produce ends up discarded, spoiled or eaten
by pests. Eliminating waste in the path from
farm to mouth could boost food available for
consumption another 50 percent.”
Because aquaponics systems are raised off the ground
they tend to have fewer pest issues than traditional
agriculture. And because aquaponic farms can be set
up anywhere, producing food directly within densely
populated communities can be implemented right now,
with no new technologies needed. The path from farm
to table can be made as short as down the block or
even from back yard to table. Thus, aquaponics is an
attractive way to localize food production and to cut
out the waste inherent in the long paths we have from
farm to market to home – paths that could be reduced
to near zero with widespread aquaponics.

Grow Your Own Series:
Scrumptious salsas, south of the border dishes,
along with a variety of Asian and Indian delicacies
just aren’t the same without the unique zip of
different parts of the cilantro plant. Admittedly,
there isn’t any middle ground with this herb when it
comes to taste buds. You either love it or hate it. If you en-
joy the taste, you can’t beat the just-picked vivaciousness it
adds to cuisine. While it is available dried, cilantro is at
its divine best freshly snipped from the plant. Within
hours of being cut, fresh cilantro loses a great deal of
flavor, so if you’re purchasing it by the bunch in the produce
aisle, you’re already missing out on a lot. It’s simple
to keep a never ending supply on hand at home.
47
CROP BIOGRAPHYFor many people, cilantro is excitingly new and trendy. Actu-
ally this wildly popular ingredient is as old as the hills and used
in many foods and confections we’ve been enjoying forever.
Properly identified as Coriandrumsativum, this name comes from
the Greek word ‘koris’ and means ‘stinky bug’. Coriander is its
common name in English and many other languages, but today
generally refers to the seed. The leaves are known as ‘cilantro’
in Spanish, which is how the plant got to Mexico and why the
leaves are so commonly used in Mexican food and the cuisine of
other South American countries.
This is one of the few plants that all parts are edible, as well as
being classed as both an herb and a spice. Dried coriander seeds
are a spice derived from the sweetly fragrant, lacy flower heads
that are used ground or whole in cooking, baking and preserv-
ing. The pungent leaves and stems are classed as an herb, and
together with the roots are used in cuisines from around the
world. Which plant part is favored most often, depends on what
culture created the recipe.
For those who aren’t aware of it, there is a defining difference
between an herb and a spice, though we use these words inter-
changeably today. Spices are fragrant or aromatic plants parts
that are also edible. Herbs also have healing properties used for
medicine, beneficial properties used in cosmetics and food pres-
ervation, along with adding great flavor to food or drink.
BENEFICIAL ELEMENTSThe earliest record of health benefits from the coriander or ci-
lantro plant is in ancient Egypt where it was brewed into tea as
a cure for urinary tract infections, as well as made into salves
and poultices.You know there is something truly special about
a plant when its seeds are buried with King Tut to use in his
afterlife. Cilantro tea is still used in holistic medicine today and
in traditional Chinese medicine for centuries to treat disorders
of the stomach. The Greeks also used the essential oils from the
foliage and stems for making perfumes.
It is known to be high in antioxidants and has antibacterial, anti-
fungal and anti-inflammatory properties and has shown excel-
lent results in treating diabetes where it lowers the blood sugar.
Cilantro is also used in the U.S. today for fighting cholesterol,
and research shows it is twice as effective at killing Salmonella
as gentamicin.
SEED VARIETIES & CROP PLANNINGFor those who try to time outdoor garden harvest of toma-
toes, jalapenos and cilantro for the most heavenly of salsas, the
heat required to finish off the peppers and tomatoes makes the
plants quickly bolt and turn into coriander. As soon as the plant
47
begins to form flowering stems, the sought after flavor of ci-
lantro is ruined as the leaves become bitter tasting. This makes
indoor growing of cilantro even more valuable year around.
Coriander, like all other cultivars, has been paid great attention
to by hybridizers. You will find seed varieties available that are
sold as having improved flavor and slower seed setting. Still, this
annual performs best for prolonged cilantro harvest at cooler
temperatures, so be sure to make note of this inherent trait.
Pinching back flower stems buys you a little more foliage harvest
time, but not much. For continual harvest, it is better to start
new seeds about every 4-5 weeks to ensure that you have a
continual supply of fresh cilantro for whipping up your favorite
dishes.
All varieties of cilantro or coriander mature to about 60 cm tall
at flowering, so be sure to have ample height for lighting adjust-
ment as they grow.
SOWING & GROWING INFOCilantro is a great candidate for indoor gardening with its hardy
constitution, minimal light requirements and preference for
lower ambient temperatures. With good grow lighting, you can
enjoy great success in potting soil, but it is also a simple crop for
hydroponic containers, and Nutrient Film Technique (NFT) or
drip irrigation systems. In a greenhouse it is difficult to maintain
the climate for this crop and it is prone to fungal infections. Days
that are too short cause the plants to quickly thin, wither and
die off, so don’t cheat your plants out of any of the required
sunshine hours.

you will want to start and finish it in the same medium. The
best mediums for hydroponic growing of cilantro are high quality
free-draining soilless mixes or sterile media. Seeds start best at
20-24 C, and will germinate in 5-7 days. Cilantro is best started
misting the medium twice a day and keeping the container in a
covered germinating tray or sealed plastic bag. Maintain full sun
lighting for 12-14 hours each day. Plants are ready for your drip
irrigation or NFT hydroponic system when the seedlings are 5-7
centimeter tall. The plant’s preferred daytime temperature is
24 C and 15.5 C at night with no more than 75% humidity and
a minimum of 11 hours of sunlight a day. Higher grow room
temperature brings bolting rapidly. You want only the immature
parsley-like leaves for cooking. Once the feathery leaves that
precede bolting appear, you might as well allow it to produce
seed. The feathery leaves are bitter and of no value.
You can expect good harvesting in 4-6 weeks. If you can’t wait
that long to whip up some salsa, you can begin cutting as early
as when you have about 15 cm of leaf and stem available. The
plants will continue to generate new stems, as their goal in life
is to flower and set seed. Just don’t expect them to grow thick
and full in the face of your impatience for culinary ingredients. At
the same time, trimming helps to stall bolting. If you’re after both
seed and leaf, plan your crop and harvest accordingly.
Controlling the heat that causes cilantro to quickly bolt and start
the seed setting process is much easier to accomplish with light-
ing versus summer temperatures outdoors. This plant does very
well under standard fluorescent or high output fluorescent lights
and High Intensity Discharge (HID) grow lights. With the thin
leaf structure and hot HID lights, you will need a fan with the
power to circulate air rapidly enough to prevent over-heating of
your crop. The last thing you want after successfully producing
great plants is to burn the uppermost foliage.
Nutrients for cilantro will be ‘grow’ solutions that are high in ni-
trogen for increasing leaves and roots as opposed to flower and
fruit. If your interest in growing fresh cilantro is more business
orientated, plan on the full 6 weeks for your first crop harvest.
You’ll find a good market for this fast growing herb in super fresh
condition almost anywhere, especially when organically grown
which will bring the highest wholesale crop income.

Coming from the north, east or west it seems like
a little hill grown over by grass. Approaching the
Earthship from the south, one finds a crystal-like
greenhouse instead. Surprising, but with a moment’s
thought, you realize that the windows are facing
south for a good reason. They are directed toward
the most sunlight, toward where the sun gives life
– in the Northern hemisphere, anyway. And this is
one of the key concepts of what Earthships are all
about: to enable one to live comfortably with what
nature has to offer.
Earthships
51
Public Park Nooterhof in the city of
Zwolle (the Netherlands) lodges one
of these Earthships. This Earthship
functions as a public tea house, open-
ing its glass doors to visitors fascinated
about living in and with the earth, and
outside the paradigm of the modern
urban world.
THREE PRINCIPLESKnown as radically sustainable green,
these curious buildings covered in dirt, not only spare the en-
vironment, but help improve several issues the environment is
faced with nowadays. As is often the case with brilliant ideas,
the principles behind an Earthship are surprisingly simple. In
fact, the buildings leave anyone first looking into their concept
startled by its simplicity. Three principles make Earth-
ships extremely green: the use of recycled products,
self-sufficiency for its inhabitants, and the implementation of
sustainable technologies.
STACKED TIRES FILLED WITH EARTHStanding next to the Earthship’s 50-100 cm thick walls makes
you realize that they are nearly impossible to penetrate, or
even to disturb. It is discarded car tires, stacked like bricks
51
and jam-packed with earth, that make
up the building’s frame. Visitors of
the tea house are allowed a peak into
the Earthship’s outer walls. A small
piece of the northern wall has been
left unfinished. It shows a couple of
the thousand discarded car tires that
shape the walls.
However impressive, not car tires but
earth is the humble secret ingredient
that makes up the Earthship. Just as the building’s name
suggests. Earthships use earth as their weapon in a building’s
never-ending battle with the ambient air temperature-with
hardly any intervention of air conditioning or heating. Earth
functions as thermal mass that passively absorbs natural heat
when the sun is out. During the night or on cloudy days, the
earth gives its stock of warmth back to the room. This way,
even in climates as chilly as the Dutch have, Earthships provide
for a constant indoor temperature year-round with a minimum
of utility bills.
GLASS WALLSDon’t assume that an Earthship will have an aesthetics defi-
cit. Quite the contrary. Its car tire, earth-filled walls are

normally plastered and painted over making them appear
similar to those of an elegant, modern adobe style house
that would fit into any community. The inside walls, how-
ever, are the walls that allow for creativity in interior de-
sign. Looking at these artsy walls you would almost forget
that they are sound-damping, temperature moderating as
well as fine-looking.
EFFICIENCY AND SELF-SUFFICIENCYNow that the ‘earth’ part of the concept has been ex-
plained, the mystery remains why these buildings are
dubbed ships. This piece of the puzzle will fall into place
at the moment one enters an Earthship. Walking into one
of these self-sufficient capsules feels like boarding a ship.
Suddenly you are separated from the world - autonomous
even. For Earthships are not connected to any power, gas,
water or sewage lines, they are fully self contained. Not
only does this trigger a strong feeling of independency, it
also allows for more efficiency in terms of energy, water,
economics and environment.
Rainwater that hits the Earthship’s roof is collected, fil-
tered in plant troughs several times, and then used and
reused. Starting off as drinking water, it seconds as shower,
washing machine, and toilet water, after which it is finally
used to water the plants. And solar panels on top of the
roof generate enough electricity and warmth for a family to
get through a normal day.
THE FIRST EARTHSHIPOne tire at a time, an experienced international Earthship
crew finished construction of the Dutch tea house in 2009.
This was the first Earthship built in the Benelux Union area of
Europe, but certainly not the very first of its kind. Introduced
by American eco-architect Michael Reynolds, the prototype
Earthship was built in the desert of Taos, New-Mexico.
Reynolds has been devoted to building houses out of natural
resources and discarded items since graduating from the Uni-
versity of Cincinnati in 1969. His conviction that, with the right
formula, products can be recycled to form buildings that won’t
spoil the resources and beauty of the earth, led him to design
the first Earthship in the 1970’s. He has authored five books
on the topic, and directed the film ‘Garbage Warrior’ in 2007.
WORLDWIDE HYPEThe tea house in Zwolle is just one of the many Earthships
that can be found worldwide. After some start-up trouble,
they now have reached global celebrity status. Around the
world today, you will find hundreds of Earthships with doz-
ens of specialized crews building more of these uber green
structures. Each building is custom made to fit the climate
it is placed in, and through a process of trial and error, each
new Earthship is a bit better than the last.
As for the Netherlands, after having introduced Earthships
to the Benelux, the country is currently the first in Europe
to develop an official Earthship district. Last spring con-
struction began on twenty-three more of these exciting
self-sufficient buildings in the city Olst.
YOUR CUP OF TEA?Earthships are remarkable buildings that enable civilized
living while helping to restore the exhausted and damaged
environment. Anyone interested in these sustainable and re-
cycled buildings can visit the tea house Earthship in Zwolle.
Reflecting over a cup a fair-trade tea here makes you realize
all too well the beauty and comfort of radically sustainable
living. And while you are there, don’t worry about enjoying
that piece of pie: it has been locally grown. 3

Toi’s job is keeping Korn sounding good and feeling good.
Their jobs require the highest level of dedication. Eleven
albums, countless concerts and running the sound both
on the road and in studio, these guys work grueling hours
and have tons of responsibility. The rock and roll lifestyle
can be a killer—literally. The members of the band all gave
up all drugs (including alcohol) years ago. They made a
decision to live sober, healthier lives and focus on mak-
ing music. But when it came to their diets nothing had
changed.
“I didn’t know any better than to serve them the stan-
dard of modern American cuisine, fast food and junk
food,” Jim lamented. Then, about two years ago, Jim
spoke to record producer Ross Robinson. “He told me

was tough and the diet that
went with it was just not good
for them.
So Jim decided to replace pro-
cessed junk food with healthy
alternatives. He made daily vis-
its to Whole foods and Trader
Joes. Kale chips replaced regular
chips. Salads took the place of
chips and pizza. Within just a
few months the guys were look-

out Ross was 100% on the money and the band members
became hooked, so to speak, on healthy eating. The next step
was to cut out all the shopping. “Few folks really have the
time to go shopping every day, just to enjoy fresh fruits and
vegetables.” That’s when Jim first thought about growing his
own garden—how could it be any fresher?

Toi approached hisfriend, Pat Gallager, about their garden
aspirations. Pat owns The Hydro Store in Reno Nevada,
and manufactures a bucket-style system for growing hy-

garden was planted.
In the beginning of this year I was contacted by Pat and
seven days later I landed at LAX and was on my way to
the studio in Bakersfield, CA. Originally Toi had an idea to
set up an 2.4m X 2.4m grow tent garden producing food
hydroponically. I contacted some industry friends and
quickly we got hooked up with a tent from Secret Jardin
and a kickass grow room controller from Grohause.
However, in the process of discussing their requirements,
plans quickly started to turn into something bigger. To-
gether we conceived the plan for the 30 X 8 foot room
Korn had available for growing fresh produce.
Here is the fun part. This garden is going to grow, literally.
In the process of discussing their requirements, the plans
quickly started evolving into something bigger. Together we
conceived the plan for the entire 9 X 2,4 m room Korn had
available for growing fresh produce. This is just the beginning.
In a couple of weeks I’m back at Korn’s studio to finalize the
set-up of a new and bigger grow room. Check out the next

Fungi, Molasses, & ROCK PHOSPHATE
Many plants go through a juvenile stage where they sharply increase in size before shifting
their energy into flowering and fruiting. The size plants reach during this stage has an impact
on how much harvest they produce.
Beneficial fungi, molasses, and rock phosphate have been used to help boost plant growth
during this critical stage for years. They work in harmony to help plants thrive.

Fungi, Molasses, & ROCK PHOSPHATE
THE RELATIONSHIP BETWEEN MYCORRHIZAE AND THE PLANT IS A SYMBIOTIC ONE; BOTH ORGANISMS
BENEFIT FROM THEIR ASSOCIATION WITH EACH OTHER
The two most important fungi for most gardeners are
ecto-mycorrhizal, and endo-mycorrhizal.
Ectomycorrhizae form primarily on tree and woody plant
roots, although some can form on a wide variety of plants.
The fungus forms a covering on the roots, and then branch-
es out into the surrounding soil. Similar to hair ex-
tensions for roots, this fungal web called hy-
phae both extends the reach of the root
system, and increases the amount of
surface area collecting nutrients for
the plant. This network of nutri-
ent collecting hyphae is anchored
between the cortex cells of the
roots. The hyphae pick up nutri-
ents from the soil, and transport
them to the plant in exchange for
carbohydrates made by the plant.
Certain varieties also have antibi-
otic properties, which help protect the
plant from infection, and the sheathing of
fungus on the roots offers some protection from
nematodes. Since the hyphae strands are thinner than
roots, they not only extend the reach of the root system
by meters, but they can also exploit smaller nooks and
cracks in the growing media. One milliliter of colonized
soil may contain up to four meters of ectomycorrhizae.
For most other green leafy plants including vegetables, en-
domycorrhizae is the more important fungus.
Instead of helping the plant by extending the root system,
they improve the existing root system. Where ectomycor-
rhizae help by moving nutrients into the plant, endomycor-
rhizae help move nutrients within the roots themselves,
speeding them to the rest of the plant for use. Weaving
itself into the cortical cells of the roots, endomycorrhizae
Since beneficial fungi take time to establish and colonize
the root system, they are best introduced early. Mycor-
rhiza fungi are beneficial and assist in nutrient collection
and uptake. Adding carbohydrates to a nutrient solution
is a gardening trick for boosting plant performance going
back to at least the 1960’s.
Mycorrhizae (fungus-roots) are found
naturally occurring in healthy “live”
soil. Sterile hydroponic media may
require a spore inoculation to es-
tablish colonies. They are caused
by mycorrhiza fungi infecting a
plant root and the two together
are what are known as mycorrhi-
zae.
Plants with well-established mycor-
rhizae tend to perform better than
those that do not. Approximately 90% of
all plants can benefit from some form of mycor-
rhizae, including trees, shrubs, and garden plants. The
relationship between mycorrhizae and the plant is a sym-
biotic one; both organisms benefit from their association
with the other. The plant provides a carbohydrate source
for the fungus, and in return, the fungus helps assist the
plants in nutrient uptake, drought resistance, and blocking
their environmental niche from pathogenic fungi. It is bet-
ter to have helpful roommates than destructive ones, so
making sure beneficial fungi take up the space can prevent
something worse from moving in. Mycorrhizae collect and
process nitrogen, phosphorus and a variety of micronutri-
ents and pass them to the plant. Of particular use is their
ability to increase phosphorus uptake, which dramatically
increases over non infected plants.

tablished, the infected roots should serve as a host to
allow the fungus to spread throughout the root sys-
tem. Much like a small colony of mold will take over an
entire loaf of bread; in a healthy root system mycor-
rhiza will spread to fill the available space. Plant im-
provements from inoculate use are particularly pro-
nounced when used early in poor or sterile mediums.
In soil that already contains high levels beneficial fungi,
adding more spores has a less pronounced effect.
Mycorrhizae thrive on carbohydrates, which is part of
what they receive in payment from the plant in exchange
for helping the plant thrive. One way to boost benefi-
cial microorganisms including mycorrhizae is to feed
them with a carbohydrate additive such as molasses.
Carbohydrates (saccharides) are molecules with spe-

THE BENEFITS OF ADDING CARBOHYDRATES ARE MOSTLY INDIRECT; THEY FEED THE BENEFICIAL MICROORGANISMS AND MYCORRHIZAE WHICH HELP THE PLANTS
form small structures called arbuscules. These arbus-
cules are where the fungus delivers the transported
nutrients for the plant to receive, and picks up carbo-
hydrates supplied by the plant. Nutrients transported
by endomycorrhizae include nitrogen, phosphorous,
potassium, calcium, sulfur, and zinc, with an emphasis
on phosphorous uptake. Of particular use is where
rock phosphate is being used as a phosphorous source
instead of the more available superphosphate, as en-
domycorrhizae speeds the solubility conversion. Add-
ing endomycorrhizae generally replicates the effect
of increasing the strength of phosphorous in nutrient
solution by improving existing phosphorous uptake.
Although commonly already present in healthy soil,
mycorrhizae fungus levels can be increased by adding
powdered spores (inoculants) available at garden and
hydroponic shops. Sterile media and poor soils can be
brought from a complete absence of mycorrhizae to
abundance with the use of inoculants. All they need is
food (carbohydrates), water, and half a chance. High
applications of chemical nutrients can be detrimental
to development, so this system is less appropriate for
“goose pate” style gardens where nutrient is supplied
to the plant at the upper end of its ability to absorb.
This can create an apparent paradox where continu-
ing to apply additional nutrients can impede the plant’s
nutrient absorption. For example, killing off the endo-
mycorrhizae will require additional phosphorous to be
added to make up for the loss in efficiency and uptake.
If using mycorrhizal inoculants, apply at the beginning
of the season to establish the colonies early. Once es-

cific combinations of carbon and
water. A subset of carbohydrates
are the sugars ending in “-ose”.
For example, table sugar is sucrose
(C12H22O11), milk sugar is lactose
(also C12H22O11, but the atoms are
arranged differently), blood sugar
is glucose(C6H12O6) and so on.
Carbohydrates store energy that
many life forms can use, people included. The “sugar
rush” from eating a lot of sweets is an effect from over-
indulging in sugars. The energy is easily converted, but
then is quickly used. Keep in mind that unwelcome visi-
tors such as ants may be enticed to visit if a carbohy-
drate banquet is available, so make sure to clean up any
spills promptly.
The benefits of adding carbohydrates are mostly indi-
rect. They don’t help the plants directly, they feed the
beneficial microorganisms and mycorrhizae which help
the plants. These microorganisms use the ready energy
available in carbohydrates to thrive and reproduce.
Cane syrup, maple syrup, fruit juice, and molasses
can all be used as carbohydrate sources. Dilute to
10 ml. per 3,8 l.) of water. Cleanliness is a must, as
these may attract insects and leave a sticky residue.
Ants may be attracted to the residue, and if hydrated
(mixed with water) and allowed to go anaerobic (stale)
these may encourage the wrong sort of fungal growth.
Molasses (also known as Treacle) is a byproduct of sugar
refining, and contains not only plenty of carbohydrates
to add to your garden, but potassium, nitrogen, and iron
as well. Many micronutrients are locked in their chelated
form and require a chelating agent to unlock them. Mo-
lasses acts as a chelating agent (like Humic Acid), by en-
ergizing the root level biology, it makes micronutrients
more readily available for nutrient uptake by the plants.
Be careful when purchasing molasses as prices vary
widely. Although all three are usable for gardening
purposes, molasses marketed as a plant additive tends
to be very expensive, molasses intended for human
consumption is moderately priced, and molasses sold
as cattle feed supplement tends
to be pretty cheap. Molasses sold
for cattle feed is often mixed with
a grain to add structure. The ad-
dition of grain not only makes the
molasses easier to work with, but
adds compostable organic material
as an additional benefit. Personally,
I tend to purchase molasses made
for human consumption, as I don’t have a large garden;
I like it on my pancakes, and in Shoo Fly Pie. Apply at
two teaspoons (about 10ml.) per gallon of water, or the
same amount per pancake.
To complete the trio, add a good dollop of powdered
rock phosphate to the mix. Not only will this provide
the mycorrhiza with a supply of phosphorous to supply
the plant, but it can also provide a suitable environment
for other beneficial organisms to take up residence. The
well fed mycorrhiza should be put to work, and what they
do best is absorb and supply phosphorous to the plant.
Rock phosphate is available in two forms, “soft rock”
phosphate, and “hard rock” phosphate. Soft rock phos-
phate contains a higher amount of immediately available
phosphorous, and is usually the choice for container
soil enhancement. Hard rock phosphate is better suit-
ed to improve a field where plants are to be grown for
several years, or where the soil is reused.
Mycorrhiza help bring phosphorous and other benefits
to plants, and carbohydrates help mycorrhiza. During
early growth is a good time to add inoculants with a
packed carbohydrate lunch and rock phosphorous des-
sert to your growing media. Feeding your fungus car-
bohydrates regularly throughout flowering can have the
end result of giving your plants a phosphorous boost, and
reintroducing spores can help reestablish lost colonies.
Beneficial fungi help with keeping plants well fed, and
proper nutrition is one of the keys to bountiful har-
vests. Embrace the fungus among us, feed them, and
give them phosphorous to carry.
Peace, love, and puka shells. 3

6 Too Much is Never Good!
The wisdom of moderation is first taught to us as
children and rings true until the day we die. Too much
of anything can be bad for us, and it’s the same way with
plants. Moderation is key. Don’t overwater your plants.
Don’t overdose them with nutrients. Instead of feeding
them half a gallon of water at once, use moderation. Spread
that half a gallon out to four different feeds spaced through
the day. You don’t drink a gallon of soda all at once. You
drink it one glass at a time. The same goes for your plants.
Too much is stressing them out. Moderate.
Measure, Monitor and Check
Measuring is one of the most important things when
growing. Don’t just measure your temperature in one
place. Measure it in multiple places to make sure your
climate is the same everywhere in your grow room. In
addition, it’s good to know what happening when you’re
not looking at the instruments. Get a data logger that
can tell you what’s going on when you’re at work or
asleep. Make sure your water is the right temperature by
measuring it, and at the same time make sure the pH and
EC/TDS are correct as well. The same goes for lighting. Get
a light meter to make sure it’s evenly distributed. Monitor
all these parameters. Correct them when necessary. You
will see improvements instantly.
Whatcha Doing That For
Know what you’re doing before you’re doing
it. I know this sounds lame, but a lot of growers
do stuff without knowing why they are doing it.
Think before you act. Why are you upping the dose?
Why are you changing the height of your lamps?
Sometimes the question is just as important as the
answer. If you’re unsure about how to fix a problem
- check out the internet, call a friend or visit your
local hydro store. Don’t make hasty decisions
without knowing the outcome.
10 TIPS: BE A BETTER GROWER INSTANTLY!
Quality in - Quality out
Using quality items saves you lots of trouble in
the long run. Saving $40 on a pH meter seems like
a good idea when you’re in the store. Somewhere
down the road when you need to calibrate it or need
replacement parts, you’ll discover it wasn’t your best
idea. The same goes for critical items like ballasts, fans
or carbon filters. You don’t want them to break or
fail in the middle of your grow. Also, your substrate is
very important. A cheap bag of soil or media is cheap
for a reason. The quality of the components used in
substrates make up a big portion of the price. Going
into this cheap will hurt your bottom line in the end
Don’t Skimp on Climate Control
Climate is essential for a plant to survive or thrive. With
a bad controlled climate you can be sure the outcome of
your grow isn’t what you expected. I understand an A/C
is expensive but it’s even more expensive to buy an extra
A/C because your initial A/C can’t cut it. The same goes the
exhaust fan if your growing without A/C, bigger is better.
Not only will it cool quicker but it also makes less sound
because your exhaust fan doesn’t have to work as hard.
Prevention is Better than Cure
It is better avoid a bad thing from happening than
it is to fix the bad thing once it has happened. So
what can you do right now? Run a tight operation.
Clean your grow room, and don’t let dead leaves or
plant materials lay around in your room. Clean before
starting a new grow. It’s also very important when
you’ve been outdoors or inside a friends grow room to
change your clothes. Another great natural prevention
is the introduction of beneficial bugs into your grow
room. This truly “bio control” method helps you
prevent and fight pest infestations by introducing their
natural enemies in your room before they can get to it.
Should mites come along they won’t have a chance in
getting to your crop. Instead, its dinner time for their
natural adversaries.

10Spend More Time in Your Garden
Don’t just spend time sitting in your grow room.
Look at the plants closely. Use a magnifying glass
to see things better. The more time you spend with
your plants the better you can “read” them, or see
problems before the disaster strikes. For example, a
spider mite infestation doesn’t just explode. It starts
with one plant and then steadily becomes more and
more. When you see massive webs across your plants,
you’re too late, and you haven’t spent enough time with
your plants. The same goes for malnutrition or crop
deformation. It started small, with one plant. When
you’re onto it early, you can still steer things back in
the right direction.
Be Passionate
Good relationships are formed with passion.
It isn’t any different with the relationship
between you and your crop. Being passionate makes
everything much easier, more fun and makes the
learning curve less steep. Grow because you want
to grow and focus on things you like to do when
growing. Don’t dwell on the stuff you dislike. If
you need to do something you dislike - turn on the
tunes and dream about better times. Just remember
the more you focus on the positive, the better the
outcome will be.
Educate Yourself
The thing that sets experts apart from novices is
education. They know how to recognize problems,
and how to correct them. You’re reading this magazine,
so you’re well on your way to a good education. To
become an expert, you need to do more. Buy a book
on growing plants, take a subscription on Garden
Culture, get a DVD and above all read more on the
internet. You’re never too old or young to learn. Even
experts with 25+ years of experience under their belt
can still learn new things as long as they are open for it.
Keep it Dark
How do you feel being rudely awakened in the middle
of the night with a big flashlight in your face? That how
your plants feel every time you interrupt their rest to work
in your grow room or to show your friends. Just don’t do it.
Buy a green LED light to work or look in your grow room
when your plants are awake. Also it’s important to make
sure your room is actually dark when the lights are off. Plants
can have a lot of stress with light leaking into the grow room,
so make sure it’s dark. Leaks are easyly spotted by standing
in your room with the lights off in the middle of the day.

“SOMETIMES THE QUESTION
IS JUST AS IMPORTANT AS THE ANSWER”

COLUMN I GARDEN CULTURE
gardenculture.net
I first became aware of Genetically Modified Organisms (GMOs) when press
releases from Calgene, Monsanto and other large biotech companies started
crossing my desk in 1995. I felt honored and proud that these large companies even
knew Growing Edge existed, the magazine I was publishing at the time.
BY TOM ALEXANDER
Calgene created a tomato called, Falvr Savr, which through
genetic engineering slowed the ripening process preventing it
from softening and rotting, resulting in a longer shelf life, yet
retaining its natural color and flavor. It seemed cutting edge. So
without knowing all the specifics, both good or bad, pro and
con, I wrote a cover story in Growing Edge magazine touting all
the talking points that were in the press release.
The Flavr Savr tomato eventually was a failure due to only
yielding 40-50% of traditional field grown tomatoes. Calgene
was eventually bought out by Monsanto, who is now the largest
GMO company in global agriculture.
My cover story created a firestorm of response from organic
growers and environmental activists. So much so, that a few
issues later, I wrote another cover story titled Frankenfood. In it
I presented the views of people and groups who were alarmed of
the dangers of GMOs
for the future of
agriculture, gardening
and consumers
eating the genetically
engineered food.
Unlike traditional
hybrid breeding
where like species are
deliberately crossbred
for desirable traits.
Genetically modified
breeding takes genes from distinctly different plant species
creating a totally new variety of plant. Many of these genetic
modifications have tried to boost nutritional benefits or
productivity, but the two main traits that have been added
to date are herbicide tolerance and the ability of the plant to
produce its own pesticide within the plant. These results have
no health benefit, only potential economic benefit for the
biotech companies.
The profit motive has made many people question the safety
of the GMOs. Scientists who study these GMOs must sign
nondisclosure agreements, leaving the biotech company free to
approve or disapprove releasing the results of any GMO studies.
It has been difficult to find independent funding to conduct
unbiased health studies of genetically engineered crops. Studies
conducted or funded by GMO companies may be skewed to
their advantage and negative results may be withheld from
summary data shown to regulators and the public.
What is outrageous is the pollen from field grown GMOs
trespassing and polluting crops miles away from the GMO crops.
When the trespassed upon grower replants saved contaminated
seeds, Monsanto sues them for patent infringement. Monsanto
has already filed lawsuits against hundreds of farmers for illegally
using GMO patented seeds, and there have been judgments as
high as a million dollars, with the average judgment being about
$170,000. GMO pollen pollution can ruin an organic farm’s crop,
profit and reputation.
The solution to this problem is to grow as much of your own
food as possible, hopefully far enough away from a commercial
farm growing GMO crops. Reading every issue of Garden
Culture magazine will help you do that.

since 1980. He published Growing Edge magazine from 1990

In final months of 2010, at the height of the Wikileaks scandal, the major online financial institutions
VISA, Mastercard and Paypal moved to cut off the supply of donations to the site, under pressure
from powerful governments around the world. Faced with ruin, Wikileaks turned to an alternative
currency. One that wasn’t controlled by any government around the world. A currency that had
essentially been created with the press of a single key, by an enterprising young programmer who was
known in the cybersphere as Satoshi Nakamoto. It was called bitcoin.
ers there are, the less each one re-
ceives, and the system is designed to
run for a twenty year period, yield-
ing no more than 21 million bitcoins.
It is the combination of these fac-
tors that give bitcoins their value, in
much the same way as gold acquired
more value than water in the an-
cient world, because it was limited
in quantity and took a great deal of
effort to extract.
Almost as soon as mining began, Bit-
coin exchanges opened on the web.
If you can’t be bothered spending
your own money on a mining ef-
fort, then you can simply buy a miner’s coins with
conventional money through a more traditional digi-
tal currency system such as paypal. At the peak of
their value, a bitcoin was worth more than $16.83
although market fluctuations and other factors have
since brought the price back down to about $5.61.
For your cash, you get what is essentially a block of
uniquely encrypted data. It cannot be replicated, and

Twenty years of aggressive
growth on the internet has given
us a string of dotcom billionaires.
From Larry Paige to Mark Zuck-
erberg, the ability to conjure up
vast sums of money simply by
having the right idea at the right
time is nothing new. But what
Nakatomo was trying to achieve
with bitcoin was something dif-
ferent. His system mimicked the
popular peer-to-peer networks
already used by millions to down-
load and share their favourite
games, movies and music; it also
incorporated new anti-spamming
and cryptography technology which would enable it
to create money literally out of nothing.
It functions on a simple principle. Bitcoins can only
be produced by completing complex mathematical
puzzles, a process referred to as mining. The puzzles
require a real world investment, in terms of comput-
ing power and the energy required to run a proces-
sor, and prospectors are rewarded by the occasional
trickle of bitcoins into the system. The more min-

it would take a million times more
work to fake the file than to create a
real one. If you delete the encrypt-
ed data, or damage the computer it’s
stored on, it’s gone. Other than that, it works just
like any real world commodity. You can spend it at an
exchange, or with a retailer – anyone else who runs the
bitcoin software. You don’t register your name, and
none of your personal details are included in the coin.
Everything is tied to a single bitcoin address, secured by
incredibly complicated, paired encryption keys.
The irony is that the supposed anonymity of bitcoins is
a fallacy. The lengthy chain of data encrypted by each
computer includes all of the transactions ever pro-
cessed by the system, linked to the various IP addresses
of the users. With enough forensic investigation, any
particular transaction can be traced back to a physical
location. There are now sites that offer what is called
a bitcoin “fog”. This fog acts as a mixing service where
funds transferred to the fog get mixed with other us-
ers’ funds and when requested are paid out in multiple
randomized transactions to further obscure the source
of the money.
SO WHY DID SATOSHI NAKAMOTO
CREATE BITCOIN, AND
SUDDENLY DISAPPEAR OFF THE FACE OF THE WEB?
So why did Satoshi Nakamoto cre-
ate bitcoin, and suddenly disappear
off the face of the web? He had
done nothing illegal and he didn’t
stand to make some outrageous,
immoral level of profit from floating the company a year
down the line. Like a 21st century Salk, the creator of
the polio vaccine, he gave his invention away. There
have been suggestions that Nakamoto hoarded a stash
of bitcoins before the software’s release, and that at
the optimum moment in the bitcoins twenty year lifes-
pan he will release them onto the market and make mil-
lions. But like everything else surrounding Nakamoto,
it is merely rumour, heaped on speculation, stacked on
a wobbly pile of guesswork. Is he a single individual? A
cadre of programmers working under a collective alias?
The other coders credited with developing the bitcoin
technology, and with maintaining it, stay tight-lipped
about his identity. For them, the individual isn’t impor-
tant. The project is more about good old-fashioned
rebellion. A reaction to the financial irresponsibility
demonstrated by the world’s leading institutions over
the last five years. It’s about taking digital currency out
of the hands of administrators and governments, and
putting it back in the hand of the private individual. 3

With farm land decreasing at the same time that population numbers are increas-
ing globally, vertical hydroponic gardens may be one solution to the world’s food
shortages. Being ecologically and economically sound, hydroponic gardening is one
of the fastest growing areas of patenting in the U.S. today. The trend is far from
restricted to the U.S. Many innovators across the globe are creating these gardens
in urban environments.

WINDOW FARMING I GARDEN CULTURE
gardenculture.net
BY MELANIE VOTAW
Some of these farms are large scale, such as
the vertical greenhouse called Plantagon,
which is set to be built in Linkoping, Swe-
den. The concept is a helix system in
which plants are transported on a spe-
cial elevator. The crops grow during
the slow ride down the helix, and an
automatic harvesting machine allows
the food to be harvested in batches.
A smaller scale, grassroots urban
agriculture movement was launched
in New York City in 2008 by Britta
Riley and Rebecca Bray. What start-
ed as a simple idea has since turned
into a worldwide movement and a
company called Windowfarms. More
than 33,000 people now participate in
the Windowfarms community.
Their concept was created for people to
become more nutritionally independent.
Using a vertical stack of recycled bottles in
which plants are rooted in clay pellets with no
soil, a pump at the bottom sends liquid nutrients to
the top. The nutrients then trickle down through the root
systems of the plants, and the roots remain compact, re-
quiring less space than plants grown in dirt. As a result,
organic vegetables can be grown indoors in any climate
year-round using natural or artificial light.
Riley and Bray knew that NASA had been using hydropon-
ics to explore growing food in space, discovering that opti-
mal nutritional yield can be achieved by running high quality
liquid nutrients over plant root systems. So, they gathered
some friends and created their first prototype. As Riley
said in her 2011 TED talk about Windowfarms, the first
systems were “leaky, loud, power-guzzlers that
Martha Stewart would definitely never have ap-
proved.” She and her team were able to grow
enough vegetables for a single salad a week
in their New York apartments, but they
wanted to work out the bugs in the sys-
tem and make it better. So, they opened
the idea to co-developers in what Riley
calls “open source collaboration.”
In order to encourage this collaboration,
they created a social media website that
spilled the beans on how the systems are
created, as well as what was not work-
ing. They hoped people would take the
idea and run with it. And run they did.
A number of people wanted to become
more nutritionally independent, so they
each worked on improving and customizing
the farms for their own needs.
One Windowfarms enthusiast, for example,
discovered that using air pumps instead of water
pumps would cut the carbon footprint of the system
by nearly half. Another learned by trial and error that he
could get his strawberry plants to fruit in low light by sim-
ply changing the nutrients in the liquid. A Windowfarmer
in Finland outfitted the system with LED grow lights.
As people shared their ideas and discoveries, Riley’s team
incorporated the improvements that were most likely to
benefit the majority. The end result? Manufactured kits
that became available for shipment in the U.S. and a few
other countries in the summer of 2012.
Funding for manufacturing was achieved through crowd-
sourcing. Riley’s Kickstarter.com page was begun with
the goal of raising $56,000 in Windowfarm pre-sales. She

a small amount of electricity is required to run the Win-
dowfarm. In the U.S., the average electricity cost of even a
4-column farm is just over $3.20 per year.

fruit, can be grown, with heavier plants tied to the metal

raised $288,407 instead. Windowfarms is now both a for-
profit company with a patent and a non-profit organiza-
tion. The for-profit company makes the products, and the
proceeds fund the non-profit, which focuses on the com-
munity, the movement, and education.
CREATING A VERTICAL HYDROPONIC FARM AT HOMEIndividuals can build their own Windowfarm rather than
purchase a kit using the instructions provided on the
organization’s website. Setting it up can take from a few
hours up to a full day. After that, the system is mostly self-
sustaining. Water simply needs to be changed weekly, and
some cleaning must be performed monthly.
The systems are 1.2 m tall, fit in different sized windows,
and are hung by a hook or sit on a platform below the
window (on the floor, a shelf, or the windowsill). Wide
windows can handle several columns, while tall windows
can accommodate one on top of the other. Some growers
use clip-on CFL or LED lights on timers to better control
the environment for their plants.
After the initial material costs, maintenance expenses are
minimal. If the pump is run on a timer, as suggested, only

VERTICAL IS THE FUTUREWhile Plantagon is centralized, and the Win-
dowfarms concept is decentralized, both
seek to grow food in cities as a response to
global crowding. Riley says that urbanites rely
on others more than rural dwellers. “It’s pre-
cisely when we hand over the responsibility
for all of these things to specialists that we
cause the kinds of messes that we see with
the food system,” she said in her TED talk.
As a result of these food system issues, the
vertical hydroponics trend is fully entrenched.
As more and more people move into urban
environments, growing their own food or
purchasing from sources like Plantagon may
become the norm rather than a novelty. 3

Grow Your Own Series:
FreshWasabi
If you’re a regular patron of Japanese restaurants, fiery green
wasabi paste is a familiar and welcome sight. So, it might
come as a surprise to learn that you’ve probably never
tasted real wasabi. Most restaurants use a substitute made
from Western-style horseradish and other ingredients,
including vinegar and mustard powder.
79
That’s because real wasabi, Wasabia japonica, is rare and
expensive even in its Japanese homeland. It’s native to the
cold upland streams of that mountainous country, and is
notoriously difficult to grow. It flourishes only in a nar-
row range of conditions, and most cultivars are specific to
one small region of Japan. However, commercial growers
in Japan, Taiwan and North America have slowly learned
to coax this uncooperative plant into producing reliable
crops.
Wasabi is part of the larger brassica family, which also in-
cludes the cabbages and mustards
as well as Western horseradish and
other root plants including turnips,
daikon and the familiar garden rad-
ish. Like horseradish and the mus-
tards, its fiery nostril-clearing char-
acter is a chemical defence against
predators. When the cell walls are
crushed or grated, enzymes in the
root quickly convert stored sulphur
compounds into an irritating chemi-
cal called sinigrin. It’s highly volatile
and aerosolizes quickly, which is
why you feel the effect primarily in
your sinuses.
Growing wasabi can prove a fas-
cinating project for experienced
gardeners in search of a challenge.
The plant requires lots of shade,
ideally 75 % coverage or better. It
requires high humidity and cool air
temperatures, ranging from 8-20 C,
and flourishes best at 12-15 C. In
warmer, sunnier or drier climates
the shade-type greenhouse can be
the best solution, providing shelter
79
and a microclimate that can be kept humid and tempera-
ture-controlled. A fertilizer containing sulphur will help
increase the root’s potency.
In nature, wasabi grows in a semi-aquatic environment
along stony riverbeds. If you have running water on your
property, or have an existing hydroponic system, you can
use that water to cultivate wasabi. Prepare a deep bed
or large box-shaped planter, approximately 75-125 cm in
depth. Fill the bed with stones approximately 6-8 cm in
diameter, leaving 10 cm at the top. Cover the stones with
a layer of rounded gravel the size of
large peas, approximately 6-8 cm.
Finally, fill the rest of the bed with
fine sand.
The plants will flourish best when
the water flows gently down a slight
slope, usually 2 to 4 degrees. Water
should be distinctly cool, with an
ideal temperature of 12-15 C. Wa-
ter flow should be gentle, no more
than 10 cm per second, to produce
straight and healthy rhizomes. If the
water flow is too strong, the roots
will grow in a curved shape. The
flavor will still be fine, but if you’re
growing them for sale, curved roots
don’t fetch as high a price.
Wasabi can also be cultivated on
dry land, in a light, well-drained soil
with lots of sand and organic mate-
rial. Prepare your beds in an area

land, so plan to irrigate with soaker hoses or some other
form of low-flow irrigation. Monitor your plants closely.
Provide more water if they wilt, and less if you begin to
find stem rot.
Wasabi can be propagated from seed, slips or the small
plantlets that grow around the crown of a mature plant.
Plantlets 3 cm long, with four or five leaves of their own,
can usually be planted directly into your aquatic or dry-
land beds. Place each plantlet in its own hole, about 30 cm
apart, with about 1 cm of the root left above the surface
once you’ve patted the sand or soil back into place. Plants
grown from slips or seeds must be grown to a height of
approximately 5 cm before transplanting into their beds.
The fiery roots will usually be large enough to harvest in
16 to 24 months, depending on your growing conditions.
Remove plantlets from the main stem for replanting, and
then wash the root thoroughly. Trim away any small roots
then peel the stem with a paring knife or peeler. As with
chilli peppers, it’s best to wear gloves while working with
fresh wasabi. The juices can be decidedly unpleasant if they
find their way to a sensitive spot.
Real wasabi is best when grated as needed. Japanese chefs
use a special grater made from shark skin, but a very fine
conventional grater will also work. The flavor will reach its
peak within 3 to 5 minutes, and will diminish within 15 to 20
minutes if it’s left uncovered. Fresh wasabi has the familiar,
fiery effect in the diner’s sinuses, but mellows quickly to a
sweet and complex flavor quite unlike the artificial variety.
Grate only as much as you need for one meal, then store the
remainder of the root tightly wrapped in your refrigerator.
It will keep for several weeks. To preserve your wasabi for
the longer term, slice and dehydrate the roots. Grind the
dried roots into powder in your spice grinder, and store it
in airtight packaging in a cool, dark place. 3
