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.
SELECT GROW MEDIA FOR COMMERCIAL USE
It is common to find propagators moving fresh cuttings into plugs for the initial stage of development. Once rooted plants are transplanted into stone wool grow blocks and then placed ontop of grow slabs to extend root zone development and access to water and nutrients. Selecting the correct substrate for your crop depends on many variables such as size, duration, density, and more.

REDROCK BLOCK’S USER GUIDE
- RedRock blocks are ultra-durable and made from premium material, but they should still be handled with care; Always keep mineral wool dry until use.
- Saturate plugs by spraying with nutrient solution or submerging them for about one minute. Squeeze gently or let them drain for a few seconds before placing them onto slabs.
- Transplant starter plugs into the blocks’ pre-drilled holes.
- As your fertigation system circulates nutrients and water to your plants, RedRock’s specialized wetting agent will deliver it evenly throughout your plants’ root zone.
