Air-pruning plant growing system

An air pruning plant tray comprising

• (a) a horizontal bottom wall having spaced, parallel sides and spaced, parallel ends, said bottom wall having a plurality of lower elliptical openings therein;
• (b) upwardly extending side walls having lower edges integral with the sides and ends of said bottom wall;
• and
• (c) a plurality of upwardly tapering plant cell walls having lower edges integral with the lower elliptical openings in said bottom wall and upper edges within a plane spaced above, and parallel to, said bottom wall, said upper edges defining upper elliptical openings;
• (d) a support tray having an air-permeable floor supporting said horizontal wall, said permeable floor including a plurality of openings or holes, said plurality of holes adapted for bringing air into contact with said lower elliptical openings, said support tray further including a plurality of spaced, parallel, longitudinal, and transverse troughs extending downwardly from said permeable floor to a lower spaced plane in parallel with said permeable floor, said troughs adapted to structurally reinforce said support tray, said troughs further adapted to support said permeable floor above any horizontal resting surface, said troughs having spaced, downwardly extending side walls integrally joined at their lower edges and adapted to raise said permeable floor above any resting surface.

An air-pruning plant growth system comprising

• (a) an air-pruning tray having a plurality of plant growth cells, each of said cells having an upper elliptical opening within an upper plane, a lower elliptical opening within a lower plane spaced from and parallel to said upper plane, a continuous, upwardly tapering, side wall joining said upper and lower openings;
• (b) a continuous horizontal wall joining said cells;
• and
• (c) a support tray having an air-permeable floor supporting said horizontal wall, said permeable floor including a plurality of openings or holes, said plurality of holes adapted for bringing air into contact with said lower elliptical openings, said support tray further including a plurality of spaced, parallel, longitudinal, and transverse troughs extending downwardly from said permeable floor to a lower spaced plane in parallel with said permeable floor, said troughs adapted to structurally reinforce said support tray, said troughs further adapted to support said permeable floor above any horizontal resting surface, said troughs having spaced, downwardly extending side walls integrally joined at their lower edges and adapted to raise said permeable floor above any resting surface.
