Grow table cleaning system

A method of cleaning a grow table, the method comprising:

• transporting the grow table into a cleaning system;
• within the cleaning system, spraying the grow table with a liquid;
• collecting runoff of the liquid by a mat, the mat positioned beneath the grow table in the cleaning system, the liquid passing through holes in an upper layer of the mat, thereby filtering out particles from the liquid;
• after entering the holes, the liquid traversing a plate layer of the mat before reaching a drain in a lower layer of the mat, the lower layer being non-porous except for the drain, the plate layer comprising layers of runners arranged in a grid, the grid of each successive layer of the layers is offset at an angle with respect to the grid of a previous layer of the layers, thereby the liquid traversing the layers of the plate layer must traverse the grid such that oils and debris that are suspended in the liquid will accumulate within the grid;
• flowing the liquid into a separation tank;
• and
• removing the liquid from an upper area of the separation tank and into a holding tank, allowing sedimentation of heavier contaminants from the liquid to settle within the separation tank for later removal;
• and using the liquid from the holding tank to clean the grow table.

A cleaning system for cleaning a grow table, the cleaning system comprising:

• a series of nozzles, the nozzles aimed downward toward the grow table for cleaning debris from the grow table with a spray of a liquid;
• a mat for capturing the liquid, the mat positioned beneath the grow table within the cleaning system, the mat having a lower layer that is substantially non-porous except for a drain, a plate layer comprising at least two layers of runners arranged in a grid, the grid of each successive layer is offset at an angle with respect to the grid of a previous layer;
• and an upper layer covering the plate layer, the upper layer having a plurality of holes for passage of the liquid;
• a liquid processing system interfaced to the drain, the liquid processing system cleans and sanitizes the liquid;
• and
• means for returning the liquid from the liquid processing system back to the nozzles.
