What is stone wool? Stone wool is made from basalt (rock) that is heated to 3,000°F and spun like cotton candy into long fibers (wool). The fact that it’s sustainable for the environment is an added bonus. What are the benefits of stone wool? Lightweight, pathogen-free, disease-free, seed-free Even, rapid water distribution throughout the media The most uniform growing substrate which results in consistent plant growth Inert, meaning it will not add or hold back any nutrients or water from the plant Usable in recirculating systems from first drain, reducing water and fertilizer usage Very controllable so grower is able to steer plant growth. Excellent buffer and re-saturation capability
