The RedRock Difference

Predictable Water Mobility

RedRock rockwool ensures uniform movement of water and nutrients throughout the plug, block, or slab. Our products will wet-up and dry back with predictability so growers can steer crops further than ever before. New tooling and technology blend horizontal and vertical fibers for the most homogenous and predictable water transport to date.

Eliminates channeling and dry zonesPredictable water movement and nutrient availabilityWater moves horizontally then vertically for full saturation

OTHER ROCKWOOL COMPANIES

Overall unreliable water dispersion in the root zone leading to plant stress and overall quality loss

Co-Extruded UV-Protected Wrapper

The little things make all the difference. RedRock blocks are tightly wrapped in co-extruded film that offers white exterior and black-out interior. WHITE ensures a cool root zone, BLACK keeps light and algae off rockwool, even around the outer perimeter. This recipe ensures better water management and less evaporation.
