    Ok i live kinda on a wet marshy landscape. I'm sure that the water company uses a high dosage of Chlorine in the water supply. Could i like boil this water so it won't harm my plants?​

    boilig any water would kill contamination in the water but i doubt it would eradicate the chlorine . . ur best bet is purchasing a PH kit . . the water should be 7 . . that is netrual . . the kit comes w/ ph increase . . ph decrease . . make sure ur water is at 7 ph

    chlorine wont be removed by adjusting the ph, you need to set the water out in a container open to the air, for 18-24 hours

    can you put in the liquide you use in fish tanks to eliminate the chlorine?

    or what about water from a fish tank would that be an organic alternative for a bit of nutrients too?

    I have heard of people saying you can use fishtank concoctions, though I would not do this myself. either air it out, or install a reverse osmosis filter, they are 150-200$ at most hardware stores. and pretty easy to install with simple hand tools and reading the directions.

    yes, this would speed up the evolution of chlorine, which normally occurs slowly if you just leave it out. MJ is not especially sensitive to chlorine, however, so i would test it or call your water company to see if it's even necessary.

    they test more accurately than we can, and are required to. they can give you TDS and all that.

    Hey whats up everyone iam new here. This is my first post, just take the water put it in a sterile container like a washed out milk jug. And let the water sit at room temperature for a few days. All the chlorine will go away and you will be left with some clean water. Thats what I do for my fish tank.

    FALSE, all the chlorine WILL NOT evaporate. there are some chlorates and chlorites or some shit that cant be evaporated or boiled out.

    you are thinking of Chloramine.


    from wikipedia

    so basically, you should either R/O filter, or you should add 10ppm chlorine, air for 24 hrs, then agitate and air for an additional 24-48 hours to ensure the ammonia and chlorine both dissapate.

    it does say that exposure to sunlight will cause the remaining chlorine to dissapate withing 4 hours, for those of you who need it in a hurry, though I am not sure how many pathogens an open container of water in sunlight will pick up (mold, pests and other crap in unfiltered outdoor air)

    yes you can use fish water to run threw as nutes....there are many people with recirculationg hydro systems where they use only fish tank water....imo r/o is the best, ppm of 0 starting ph of 6.5....cant go wrong there....peace az

    Wow...dumb


    Fill 1 gal jugs with water and let them chill on the windowsill. The clorine evaporates, you can speed this up with an airstone while at the same time increasing o2 content.

    Boiling would be an insane waste of gas/electricity, especially in the quantities most growers need. Think of your Co2 emissions

    ph of RO varies.


    i wouldnt recommend a ph reading of RO water anyway.....it can slowly render your meters useless....

    ph measures IONS and arent very many ions in RO water....

    I have pool test strips (for my 3 foot pool sac. lol.) but you can get them at fred meyer's or anywhere else that has a selection of pool/chlorine stuff and they test p.h. alkalinity and chlorine.

    tested my water today. NO CHLORINE at all in it. and ph 6.4
    I would have left the water out 24 hours as i normally do anyways, but then i realized i forgot to refill and leave any water out, so i tested and decided to just water without leaving it out since there was no chlorine in the water anyways.

    i was talking to a friend of mine who used to grow. he told me that the tap water in certain places is not harmful to the herb, including the area i am located in. is this fact or fiction?:confused:
