ABSTRACT:
A tank is provided with a nutrient supply, a separate water supply and a body of particulate support medium for the plant roots. A valve is provided for controlling access to the nutrient supply. The plant roots also may grow into the water supply for obtaining water separately from nutrients. In one version, the plants grow at the center of the tank, surrounded by the nutrient supply; in another version the nutrient supply is at the center and the plants grow in a ring around it. Versions for use on land and floating on bodies of water are disclosed.
