Botanicare OD Black Tray 4ft x 4ft | Fits a 4x4 Tent, 6in, 50 Gallon Meters One packetThe 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. You give up a little growing floor for it, 46 in x 46 in inside, and that trade is the entire point of the line. Capacity is still 50
