Select Grow Media for Commercial Use

RedRock Grow Blocks Pro are the stone wool grow media of choice for commercial cultivators, growers, greenhouse operators, hydroponic operators, CEA facilities, and indoor farmers.

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 on top 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.

Propagation & Nurseries

Stone wool cubes' beneficial structure and water retention properties make them exceptionally beneficial when starting seeds and rooting propagation cuttings.

Commercial Greenhouses

Among all other properties, stone wool creates a stable growth environment for crops roots, and does not spread disease, insects and weeds.

Commercial Hydroponic

The stone wool grow blocks and their properties make them an indispensable product and an ideal medium for any hydroponics growing system.

Predictable Water Mobility

RedRock Wool 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 zones
  • Predictable water movement and nutrient availability
  • Water moves horizontally then vertically for full saturation

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 stone wool, even around the outer perimeter. This recipe ensures better water management and less evaporation.
