If the ph is within range and water has no smell of chlorine, should be fine. If you can smell the chlorine, will have to let the water sit till chlorine is evaporated, which would defeat your attempts at streamlining your rituals. How about filling a five gallon bucket to let the chlorine evaporate, and use a one gallon jug to transport to the reservoir?

If you do start using your tap water, would watch the plants closely for a week or two after. May have to adjust your micronute doses a bit, too.
Rusty Trichome Reviewed by Rusty Trichome on . water question IM using a 15 gallon resevoir for my hydroponics,i change the water once every two weeks.The only reason i change it once every two weeks is that i just cant lift four 5 gallon water jugs every week.I'm wondering if i changed it once a week would you really see that much of a diffrence than opposed to 1 ev2 weeks,but my main question is can i just use my tap water instead without any serious reprocushons?,its just to much to lift all those jugs Rating: 5
