Abstract: A plant grow tray system comprising a plurality of trays comprising at least one upper tray and at least one bottom tray is provided. The upper tray has a corrugated profile with crest and trough portions, air holes on the corrugated surface, a drain basin, drain flange, and drainpipe. The bottom tray has an air-flow modifier, air flange, and a drain hole. The system is designed to allow air to be ducted or exhausted from the space between the upper tray and the bottom dray enabling the delivery of conditioned, fresh, or recirculated air directly to a plant.
