JohnnyRico Reviewed by JohnnyRico on . Hydro maintenance between grows? Hi So my first hydro grow ended with all males and now I am starting a new one. What should I do with the hydroton? I removed old roots as much as I could, but theres a still a lot of small pieces of roots attached to the hydroton. Should I boil the hydroton or just flush it really good? Rating: 5
