Not only is rockwool unfriendly to the environment ? it?s also potentially harmful to your health. New blocks can contain a lot of dust and loose fibers that can get in your eyes, mouth, skin and lungs. It?s similar to asbestos in the sense that the little fibers can lodge themselves in your lungs if you?re working with it a lot. It may not be as toxic as asbestos, but the EPA lists it as ?possibly carcinogenic to humans.? Not something that I?m willing to gamble with if I don?t have to ? there are plenty of other hydroponic media choices! If you?re using rockwool, you should be using a mask, goggles and gloves when you work with it to protect yourself.
