Where I live water is about 250 TDS. I think that RO would help, also removing any unwanted minerals in water. Growing DP PowerPlant 1000W HPS lighting.

I'd appreciate any input form those w/ experience. Thanks
Boomer1 Reviewed by Boomer1 on . PLEASE HELP! HOW IMPORTANT IS RO WATER? My tap water is 40 ppm. How big a difference is it going to make if I buy a reverse osmosis water purifier? Someone at the hydro store told me I don't need one. I'm about to start flowering and I'm willing to buy one if its gonna make a noticable difference. I would appreciate any thoughts. I have a 4X4 flood tray with 1000W Thanks :rasta: Rating: 5
