One or more plant growing trays are supported on a tubular support frame constructed of plastic pipe to provide an attractive support for the plant growing trays and to also provide a storage chamber for the proper volume of fluid growing solution. The fluid growing solution is periodically supplied to the plant growing trays by air pressure entering the tubular growing solution storage chamber and then the fluid growing solution drains from the plant growing trays and back into the tubular storage chamber. A timer control device is provided to control the periodic supplying of the air pressure to force the fluid growing solution into the plant growing trays.
