Savage growth in week 2, I'm having problems keeping the reservoir temperature controlled. I also haven't changed the water in the reservoir. Just adding R.O. water as needed ph down every couple days to regulate from a 7 to a 5.8. I'm thinking of running one more week on the same reservoir. Adding more water, Hydrogen Peroxide, EnzymeKomplete , and 1part Botanicare Pure Blend Pro Grow.
