ABSTRACT:
There is disclosed a device for holding and growing plant material by hydroponic techniques, the device including a tray having sloping sidewalls, with the sidewalls having extensions for being supported on a rail, and a corrugated bottom with the corrugations shaped to provide drainage of liquid from the bottom of the tray and to hold a water-impervious, seed-holding membrane above the corrugations so that the membrane will have a crown that causes liquid to drain toward the edges of the tray.
