Hey elway07
You can use distilled water from wally world for about $0.64 per gal.I did that for along time,till I got reverse osmosis.It hooks to the garden hose and gives me 90 gals a day.Cost about $200.00 but it pays for it's self.No more fooling with jugs of water letting them air .Just a 5 gal bucket to carry in to the grow room.But yes you want to PH the water.
Peace
