Description Rockwool cubes are made of 100% basalt rock. Rockwool grow media will provide a uniform germination and a high success rate. Completely sterile and inert – ideal hydrop onic growing medium. Reduced risk of pests and disease. Even root growth – predominantly vertical fibre structure means identical levels of resistance for each root, so roots grow evenly. Increased root development – structure of the rockwool is designed for optimum air / water balance and accelerated rooting. Uniformity – quality and structure is uniform, so water content and EC (CF) will remain the same for every plant. Re-wetting – rockwool is easy to re-saturate if it dries out, reducing the risk of root damage. Specification Packs of 10 cubes 30x30x40 Show more
