ABSTRACT OF THE DISCLOSURE A plastic tray having short legs and a perforated bottom fits securely within a plastic container, the tray being adapted for carrying vermiculite and the container being adapted for holding nutrient solution. The tray also has an enlarged upper portion defining a channel-shaped inner ledge between the enlarged and unenlarged portions thereof. An electric pump is disposed within a compartment of the tray, and a plastic tube runs from the pump into the nutrient solution and up the wall of the tray to the channel- shaped ledge, into which it snaps along the sides of the tray. The tube is perforated where it contacts the nutrient solution, and has a series of apertures along the portion snapped to the walls of the tray, such that a mixture of air and nutrient solution can be pumped through the tube into the vermiculite.
