How aeroponics works

In aeroponics, roots hang in the air inside a closed chamber. A pump sprays or mists nutrient solution onto them on a schedule.

Towers and vertical systems

A tower or vertical system stacks plant sites up a column. Depending on the maker's design, a pump lifts solution up the column, and it trickles or sprays down past the roots and returns to a reservoir at the base.

Pump, timer, and water

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 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.

Setting up a tall unit

Follow the maker's instructions for assembling and placing a tall unit.

What we do not say

We do not compare aeroponics or towers with other systems. Results vary.

FAQ

The roots sit in the air, so read the maker's instructions on pump stops and power cuts before you start.
No. Some towers spray solution and some let it trickle down. The maker's description says which.

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.
