Botanicare OD Black Tray 4ft x 4ft | Fits a 4x4 Tent, 6in, 50 Gallon Meters One liter NirvanaThe Botanicare OD 4x4 Tray Is Measured From the Outside In OD means outside dimension, and it exists to solve one specific problem. A 4x4 tent floor is 48 inches square, and most 4x4 trays measure 49 or 53 inches outside, which means they do not go in. This one is 48 in x 48 in x 6 in on the outside and drops in flat.
