Rockwool Stacker


Rockwool 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.

FloraFlex® Stacker

Allows a Rockwool user to seamlessly stack a 4 inch cube on top of a 6 inch cube or a 6 inch cube on top of a 8 inch cube, blocking light and eliminating algae, all while allowing in the necessary air a plant needs to thrive.
