What these are
On this site, a countertop garden means a small all-in-one unit with a water reservoir, plant pods or net pots, and a built-in light. Some units add a small pump.
Kits
A hydroponic kit or starter kit is the maker's bundle of parts. The maker's parts list and instructions say what is in it.
A light and water in one unit
These units put a light, a power cord, and water in one place on a counter. Keep the plug and cord away from the sink and from spills, and follow the 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. CPSC says portable GFCIs are also available "to provide on-the-spot ground fault protection even if a GFCI is not installed on the circuit."
Pods and refills
Seed pods, nutrients, and refills are the maker's products. Follow their labels.

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.
