RedRock - Commercial Rockwool Cubes, Blocks, Plugs, Slabs

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
