Drip systems: how drip hydroponics works
A pump sends solution through tubing to emitters at each plant.

How it works
In a drip system, a pump moves nutrient solution from a reservoir through tubing to emitters that drip it onto each plant's growing medium. In a recirculating setup the extra solution drains back to the reservoir. In a drain-to-waste setup it does not.
Tubing, emitters, and the pump
Drip lines, emitters, and the pump are the maker's parts, and the maker's instructions say how they fit together. Keep plugs, cords, and connections away from water, and follow every maker's instructions.
GFCIs
CPSC says a GFCI "is designed to protect people from severe or fatal electric shocks," and that ground fault protection is used "especially for circuit outlets in particularly vulnerable areas such as where electrical equipment is near water." Use a qualified electrician for any wiring.
Solution that drains away
Solution that leaves the system is still a nutrient product. Follow the nutrient label for disposal.
What we do not say
We do not give drip rates, cycle times, or nutrient strengths. Results vary.

FAQ
General information only. Water and electricity are a dangerous mix: keep plugs, cords, and connections away from water and follow every maker's instructions. CPSC says a GFCI "is designed to protect people from severe or fatal electric shocks" and to test every GFCI "At least once a month." Use a qualified electrician for any wiring. Keep nutrients and other chemicals away from children and pets. In an emergency, call 911.
