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.
