A tray construction for growing plants in which the construction comprises a one-piece substantially rigid tray frame with a plurality of plant frames mounted in the tray frame to define a plurality of plant growing containers interconnected in a unitary assembly. The tray frame may be conveniently molded from a foamed thermoplastic material and essentially comprises a plurality of substantially rigid tubular members vertically aligned and integrally interconnected in a rectangular array of a plurality of adjacent rows. The open spaces between diagonally opposed tubular members permit air to pass between the upper and lower sides of the tray frame. The plant frames are preferably frictionally held within the tubular members, and each plant frame essentially comprises a base section and a plurality of ribs secured to the base section to upstand therefrom. Each of the plant frames is telescopically mounted in one of the tubular members with the base section in a spaced relationship with the lower end of the tubular member to provide drainage openings therebetween. The ribs extend upwardly within and against the inner walls of the tubular members. |
