Abstract
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.
