A cleaning system includes a planar material beneath a soiled grow table. The planar material is non-porous except for a drain. Above the planar material is a plate layer including at least two layers of runners arranged in a grid where each successive layer is offset at an angle with respect to the grid of a previous layer. The plate layer rests upon the non-porous material. An upper layer covers the plate layer and has a plurality of holes. A roller table is provided for slideably supporting the grow table. Nozzles are positioned over the grow table and is/are interfaced to a pump for receiving and spraying liquid from the pump downwardly towards the grow table. The liquid and impurities (e.g., soil, leaves) fall to the upper layer and through the plurality of holes for cleaning and filtering the liquid before the liquid is returned to the pump.
