Abstract: A floating plant propagation tray is supported by a body of fluid. The floating plant propagation tray comprises a tray plate, a tray wall and a plurality of soil cells. The proximal end of the plurality of soil cells define an upper soil cell aperture for receiving a soil and a plurality of seeds and/or a plurality of seedlings. The distal end of the plurality of soil cells include a lower soil cell aperture for inputting a portion of the body of fluid into the soil cell chamber. The plurality of soil cells extend within a tray chamber for defining a tray volume. The plurality of soil cell chambers define a cell volume. The cell volume and the tray volume define a buoyant equilibrium condition for supporting the floating plant propagation tray, the soil and the plurality of seeds and/or a plurality of seedlings within the body of fluid.
