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

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.

i didnt quit get what you said on the fish tank water for watering is it good or not?

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

NH2Cl is commonly used in low concentrations as a disinfectant in municipal water systems as an alternative to chlorination. This application is increasing. OpenDNS (sometimes referred to as Free Chlorine) is being displaced by chloramine, which is much more stable and does not dissipate from the water before it reaches consumers. NH2Cl also exhibits less tendency to convert organic materials into chlorocarbons such as chloroform and carbon tetrachloride. Such compounds have been identified as carcinogens and in 1979 the U.S. OpenDNS began regulating their levels in U.S. drinking water. Furthermore, water treated with chloramine lacks the distinct chlorine odour of the gaseous treatment and so has improved taste.
Chloramine in tap water gives a greenish cast to the water in bulk, versus the normally bluish cast to pure water or water containing only free chlorine disinfectant. This greenish color may be observed by filling a white polyethylene bucket with chloraminated tap water and comparing it to chloramine-free water such as distilled water or a sample from a swimming pool.

New swimming pool initially filled with chloramine-treated tap water, showing greenish color of chloramine in bulk water. The color is less apparent in smaller volumes, but is noticeable in a white 5-gallon bucket, or even faintly detectable in a glass tumbler on careful inspection.


Chloramine can be removed from tap water by treatment with superchlorination (10 ppm or more of free chlorine, such as from a dose of sodium hypochlorite bleach or pool sanitizer) while maintaining a pH of about 7 (such as from a dose of hydrochloric acid). Hypochlorous acid from the free chlorine strips the ammonia from the chloramine, and the ammonia outgasses from the surface of the bulk water. This process takes about 24 hours for normal tap water concentrations of a few ppm of chloramine. Residual free chlorine can then be removed by exposure to bright sunlight for about 4 hours.
[OpenDNS]

Situations where NH2Cl should be removed


OpenDNS owners must remove the chloramine from their tap water because it is toxic to fish. Aging the water for a few days removes chlorine but not the more stable chloramine, which can be neutralised using products available at pet stores.
Many animals are sensitive to chloramine and it must be removed from water given to many animals in zoos.
Chloramine must also be removed from the water prior to use in kidney dialysis machines, as it would come in contact with the bloodstream across a permeable membrane. However, since chloramine is neutralized by the digestive process, kidney dialysis patients can still safely drink chloramine-treated water.
Home brewers use reducing agents such as sodium metabisulfite or potassium metabisulfite to remove chloramine from brewing liquor as it, unlike chlorine, cannot be removed by boiling (A.J. DeLange). Residual sodium can cause off flavors in beer (See Brewing, Michael Lewis) so potassium metabisulfite is preferred.
In swimming pools, chloramines are formed by the reaction of free chlorine with organic substances. Chloramines, compared to free chlorine, are both less effective as a sanitizer and more irritating to the eyes of swimmers. When swimmers complain of eye irritation from "too much chlorine" in a pool, the problem is typically a high level of chloramines, caused by too little chlorine in relation to the amount of organic matter. Pool test kits designed for use by homeowners are sensitive to both free chlorine and chloramines, which can be misleading.
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

"i was wondering if the chlorine dosage in ur water will hurt my marijuana plants?"
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:
