I think my roots got root rot because they were brown and had brown slime on them. I was adding doses of 3% Hydrogen Peroxide to my reservoir. This did not do anything to whiten up the roots. I was advised to get, and did get, some Dutch Master Zone to clean up the root rot. I added the Zone to my reservoir and I'm waiting for the roots to come out white but they're not. Now I'm thinking of giving the plants a root dunk/bath by dunking the net pots into a high strength solution of 35% Hydrogen Peroxide and water. Or maybe I should just add a few teaspoons of 35% Hydrogen Peroxide to my reservoir. Is it safe to add 35% Hydrogen Peroxide to my reservoir when there is already some Dutch Master Zone in it? Thanks for any input.
