REDROCK: Tight-Fit Wrapped Slabs

Custom tailored Tight-Fit film wrap on our slabs ensure better drainage and uniform water movement across the media. Water and plant nutrition are held accessible to the root zone and forced along a straight path through the stonewool to the drainage slit(s). Additionally, we have printed tracking information on every slab to ensure cultivators can check lots for quality and consistency cycle after cycle.

• Tight-Fit wrappers ensure nutrient rich water is plant accessible.
• Increased uniformity in water distribution.

Other Stonewool Companies

• Sloppy wrappers hold water unevenly and interrupt uniform drainage.
• Increased risk of wrapper tear.
• Gaps pool free-draining water.
