RO is not necessary, BUT, it removes the chlorine ... chlorine won't harm your plants, but it does kill the beneficial bacteria ... so, if using chlorinated tapwater, don't waste your money on microbial additives (Big Bloom, Tarantula, etc. etc.), they'll be killed as soon as they hit the water ... leave the water uncovered for a couple days, so the chlorine will have time to evaporate, then you can use additives, if you choose ... :smokin:
the image reaper Reviewed by the image reaper 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
