With the NEW GreenStalk Mover, you can now rotate and move the GreenStalk without stacking and re-stacking. Created exclusively for the three, four, and five tier GreenStalk Vertical Gardening System by the same family that made the GreenStalk. With the Mover, you can let water collect for a limited time with a cap or allow excess water to drain out via a drain hose. With the drain hose, you can redirect water to go off your patio or into a reservoir. Comes with a total of 6 wheels (3 of the wheels have the ability to lock). For use on a flat surface.
