ABSTRACT:
A method and apparatus for periodically supplying liquid to the root system of plants, utilizing pneumatic pressure to displace liquid in a chamber located beneath a plant support to a higher level accessible to the plant root system; and a means to release the pneumatic pressure in the chamber, allowing the liquid to re-enter the chamber, lowering the liquid to a level below the plant support. This system provides: cyclic feeding of liquid to plant roots; agitation and oxygenation of the liquid during use; re-use of chemically enriched liquid; flexibility in spacing plants during growth cycle, and provides for growing plants in individual containers for ease of handling and transport.
