A plurality of plant flats are supported on a movable plant flat support rack positioned adjacent an irrigation trough for movement between an upper position and a lower position; idler rollers on the support rack engage inclined tracks on opposite sides of the irrigation trough so that horizontal movement of the support rack results in vertical movement of the support between an upper position in which the flats are above the upper surface of the trough liquid and a lower position in which the bottom of the flats is immersed in the liquid in the trough. A portable dive assembly is connected to the plant flat for support effecting horizontal movement of the rolls.

[ What is claimed is:] [1.] A plant growing system including:an elongated open topped irrigation trough having side walls and first and second ends and trough liquid having an upper surface within the confines of the irrigation trough:a movable plant flat support rack positioned adjacent said irrigation trough for bodily vertical movement between an upper position and a lower position;a plurality of plant flats each having plant receiving cells with a lower drain/inflow opening in each cell in the lower extent of said plant receiving cell, said plant flats being positioned on said movable plant flat support rack in horizontal alignment with each other so that said plant flat support rack supports the plant flats equidistantly above the upper surface of the trough liquid and simultaneously positions said plant flats so that said drain/inflow openings are simultaneously submerged in the trough liquid when said plant flat support rack is bodily moved into its lower position; and rack positioning means for moving said plant flat support rack to its upper position in response to the application of force to said plant flat support rack in a first horizontal direction and for moving said plant flat support rack from its upper position to its lower position in response to the application of force to said plant flat support rack in a second horizontal direction.
