Floraflex Stacker (4"-6" , 6" - 8")

The FloraFlex Stackers allow you to stack your 4" rockwool cube onto a 6" rockwool cube, or a 6" rockwool cube onto a 8" rockwool cube. The Stackers conserve space in your Veg room by allowing you to use a smaller medium and then add on to it with a bigger medium during your flip to Flower.
