FloraFlex Stacker - 4 in to 6 in

Stack a Smaller Cube on a Larger One - 4 in to 6 in

Moving a growing plant into a bigger rockwool cube can disturb roots and leave the media surface exposed to light, which encourages algae. The FloraFlex Stacker sits between a smaller cube and the larger cube beneath it, so you can stack them instead of transplanting. The stacked cubes stay in place, and the design is meant to limit light at the joint while the plant still gets air.

This single unit suits hobbyists testing stacked cubes and growers who want to add them to a hydroponic system one position at a time. Buy more to match the number of cube positions you run.

Key Features & Benefits

• 4 in to 6 in stacking — joins a 4 in cube to a 6 in cube without a transplant step.
• Light blocking — covers the joint between cubes to help limit algae growth.
• Air access — leaves room for the air flow plants need at the root zone.
• Low profile — measures 0.3 in high, so it adds little height to the stack.

Who Should Use FloraFlex Stacker

Growers who use rockwool cubes in hydroponic systems and step plants up to larger cubes during vegetative growth will find it useful. It works for home and commercial setups alike.

Frequently Asked Questions

A: It is made for a 4 in cube stacked on a 6 in cube. Check fit before using it with other sizes.

Q: Why does blocking light matter?
A: Light reaching damp media encourages algae. Algae competes with plants for moisture and nutrients, so covering exposed surfaces helps keep the root zone clean.
