FloraFlex 4" To 6" Stacker

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.
