    Stonewool - 1/4 in. Cubes - Grodan RW91003


    Made of the same high-quality stonewool as larger cubes and slabs, miniature Grodan RW91003 grow cubes fit any container size or shape. They are designed as starter cubes for seed and cutting propagation. The cubes are open celled, water absorbing forms that promote rapid root formation. They are free of pathogenic organisms and require no pretreatment or further sterilization. They offer easy irrigation, optimal root aeration, and last throughout crop production. For any growing application, stonewool offers speed, ease of use, and cleanliness. This 2 cubic foot bag of grow cubes will fill approximately 23 standard one-gallon nursery pots.
