Rockwool is a state-of-the-art rooting medium used in plant propagation. Seeds or cuttings are started in small rockwool cubes and, once rooted, the cubes are transferred to a larger piece of rockwool or may be planted directly in soil. Rockwool is used in systems such as NFT Gulley, Quantum System, and the Ebb and Flow.
