Determine the Location
Locate the hydroponic system in an enclosed structure, such as a greenhouse or the basement of your house, or on an outdoor patio or deck. The floor should be level to ensure even coverage of water and nutrients to the plants in the system. If placing the system outdoors, protect the system from the elements, such as providing a wind barrier, and check the water levels more often due to water loss from evaporation. During cold temperatures, bring the hydroponic system indoors. If placing the system in an interior room of your house, add grow lights to provide supplemental lighting to the plants.
This is a flood-and-drain, or ebb-and-flow, system. The pump is set on a timer that comes on every few hours or minutes, depending on the type of plants and the humidity. Nutrients and water flood the tray and submerge the roots; then the tray drains so air can circulate around the roots.
