ABSTRACT:
A hydroponic apparatus providing a controlled environment for plant growth including artificial light and periodic flushing with a liquid nutrient. Plant growing containers filled with growth media mounted horizontally on a box like structure containing an air tight storage container for liquid plant nutrient extending beneath the enclosures containing the plant containers. Compressed air admitted to the storage tank forces the nutrient liquid up, through the laminated filter section, into the plant container from which the nutrient drains back into the storage tank. A canopy over the assembly contains electric growth lamps and a roll up trellis.
