Hydroponic culture medium par excellence, used in professional horticulture (cheap, reusable and sterile), rockwool is the substrate that has long since proven its worth:
-optimal oxygenation at root level;
-good retention of water and nutrients
-anti-rotting property;
-avoids transplanting shocks.
Nevertheless, rockwool requires some precautions of use, especially in the dry state, the ports of mask and gloves are recommended since it is irritating for the skin and the respiratory tracts.
