Abstract: A plant cultivation tray for a gravity-driven plant cultivation system includes: (a) a tray body; (b) a plurality of plant cavities in and open to a top of the tray body for holding plants; (c) a nutrient chamber internal the tray body and in fluid communication with the plant cavities for holding plant nutrient solution. The nutrient chamber is bounded from below by a nutrient chamber bottom wall lying in a horizontal plane. The tray body has at least one underside surface for engagement with a sloped gravity conveyor to rollingly support the plant cultivation tray thereon. The at least one underside surface slopes downwards relative to the horizontal plane from a rear to a front of the tray body for maintaining a generally constant depth of the plant nutrient solution across the nutrient chamber bottom wall when the tray is supported on the gravity conveyor.

Abstract: A gravity-driven plant cultivation system includes: (a) a frame; (b) a plurality of stacked conveyor assemblies mounted to the frame, each conveyor assembly including at least one gravity conveyor extending along a sloped conveyor axis; and (c) a plurality of plant cultivation trays rollingly supported on each gravity conveyor and urged to translate along a corresponding conveyor axis via gravitational force. Each tray includes: (i) a tray body having at least one underside surface parallel and in engagement with the gravity conveyor for supporting the tray thereon; (ii) a plurality of plant cavities in the tray body for holding plants; and (iii) a nutrient chamber internal the tray body for holding plant nutrient solution for the plants. The nutrient chamber is bounded from below by a nutrient chamber bottom wall lying in a horizontal plane for maintaining a constant depth of the plant nutrient solution.

Abstract: A gravity-driven plant cultivation system includes: (a) a frame; (b) a plurality of vertically stacked conveyor assemblies mounted to the frame. Each conveyor assembly includes at least one gravity conveyor extending along a conveyor axis. The conveyor axis slopes downwards relative to a horizontal plane from a frame upstream end to a frame downstream end of the frame. The system further includes (c) a plurality of plant cultivation trays rollingly supported on each gravity conveyor and urged to translate along a respective conveyor axis toward the frame downstream end via gravitational force.
