Plain language

For people growing lettuce and herbs in water at home. No picks, and CPSC's lines on water and power.
Water and electricity
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.
