Grodan 3-inch rockwool cubes, sized 75 x 75 mm with no hole, are packaged in a carton of 384. Made from spun basaltic rock fibers, these cubes provide a balanced air-to-water holding capacity that supports healthy root development and oxygenation. Sterile upon arrival and pH neutral (5.5-6.5 after soaking), they reduce pathogen risks in propagation. The seamless no-hole design enables flexible seed or cutting placement. Suitable for hydroponic systems including NFT, drip irrigation, and ebb-and-flow. Pre-soaking ensures uniform hydration for consistent germination and cloning results.
