The Cultilene Large Hole Stonewool Growing Block – 100mm has a very high consistency and very thin fibre structure, allowing optimum root development leading to increased yield.
These growing blocks have an incredible capacity for absorbing nutrient solutions while letting enough oxygen through for rapid plant growth. The design of the plug discourages tangling of roots.
Stonewool is produced from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs
