Flood trays
White inside dimension trays are made from crack resistant ABS with UV inhibitors, are 6 inches deep and use dual step sidewalls that allow two root heights. Black low profile outside dimension trays are made for tight spaces where the overall size must be exact, with taller sidewalls, rolled edges and channel grids that direct water to the drain.
Inside or outside dimension
An inside dimension (ID) 4 by 8 tray measures 4 by 8 feet inside the walls, so the outside is larger. An outside dimension (OD) tray measures 4 by 8 feet overall. Check the space before ordering.
Runoff trays, liners and stands
Runoff tray sets in 15.5 and 22 inch sit under individual pots and route drainage away through 3/4 to 1 inch barbed fittings, with optional legs to set the fall. Fabric tray liners in 4 by 4 and 4 by 8 foot turn a flood tray into a fabric bed. Saw horse stands support a tray at working height.
