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.

Use when stacking a 4” cube onto a 6” cube.
Use with the FloraCap.
