wrong....rockwool is a very alkaline calcified medium(made from molten spun rock) that needs a more acidic pH(5.5-5.8) for proper nutrient up-take,and cold or very warm reservoir temps(68-72"FH*are ideal) are the main cause of bacteria and pathogens,if anything you may have to increase the nitrogen ppm slightly also....bonbon
