I am growing in soil using Fox Farm nutrients, I have been using reverse osmosis water and considering the waste, wondering if pure water is very necessary. Anyone have advice?
No not necessary, it just insures you start off with almost 0 ppm, just let it sit out for 24-48hrs so the chlorine evaporates. But if your water has chloramine then it wont evap and youll have it in your soil killing anything organic.
