Hydroponics
Water carrying nutrients flow over plant's roots.Advantages:• No additional watering of plants is
necessary.• No soil is needed.• Faster grow time = More production
Disadvantages:• Higher first cost.• Higher operating cost.
Drip System
System• Plants are located in reservoirs of water.• Pump circulates the water from the bottom of
the system to the top.• Gravity circulates the water from the top of the
system to the bottom.
Piping Layout PipingConsists of 1" mains and ½" branches.All piping is PVC
• Easily assembled.• Low friction factor.• No corrosion.
Calculated losses due to friction.• Major losses • Minor losses
Pump controls will run pump when reservoir A is empty and turn off pump either when reservoir A is full or when reservoir B is empty.
