Chlorine in Water Debate. Do You Let it Evaporate?

lot of people always say chlorine is bad and let yoru water jugs sit overnight to let it evaporate. on this site i came across several posts about how chlorine isnt so bad. after all, plants dont absorb it anyway right? i used to use RO water, had great results. then i switched to tap because of the convenience. i let the chlorine evaporate overnight. got virtually the same results with tap. eventually, i thought fuck it, im just going to use tap water straight up with chlorine in it. still virtually no difference. i cant really say for sure. i mean to truly test it, you would need several setups with all variables the same except the water. i dont have the space/time to do something like that, but it seems to me the water is making no difference. so what does everyone think? if you use tap, do you let the chlorine evaporate overnight?

I'm coming to the same conclusion too. But one thing to keep in mind is a grower's local water district and how the local water quality is managed. I'm starting to see no difference in using tap vs tap that has sat for 24 hours but my water quality might be way better than let's say...Los Angeles. I do still let my water sit for 24 hours but will have no hesitation to use water straight from tap for emergencies (I still adjust PH though). Regardless of a growers water quality one should try it and see what happens. One might be surprised.

Plants actually uptake & use Chlorine for normal plant processes... 'an essential cofactor in photosynthesis', if you will.

I used to let it set out also ... but laziness eventually got the better of me ... and I havnt really noticed any difference tbh......

if u look your bottle of micro nutes has chlorine in it.

i still leave mine out by habbit but i never saw a difference

Yeah always left my tap water out

I also leave my water sit for couple of days usually, but I use it strait from the tap if I forget to fill the bottles.

I used to but stoped and no differences were noticed.

I use tap in my 18 gallon DWC without letting it sit...I thank the chlorine or chloramine for my clean rez, and the plants are doing wonderful.

not everybodys tap water is the same..chlorine's not such a big deal like u said, the plants dont take it in anyways...i use half distilled water and half tap just to get lower ppm levels so i can feed heavier with out burns or spots showing up on my leafs.

yeah i got a 5 gallon dwc. looks fucking amazing and water is straight from the tap.

Well i add it to keep pithium in check

Same as others I was letting the water sit out, but the last 2 waterings out of necessity I've used the chlorinated water and have seen no ill effects.

any input on organic with chlorine?
from what i know it kills all microbes in your soil, making it hard for the plant to get enough nutrients.
its a good thing for inorganic and definetly hydro.

I just discovered chloramine which doesn't evaporate and kills beneficial bacteria in soil. More and more cities are starting to use it and it sucks.

I use to leave my tap sitting out but and soon switching back to filtered or conditioned (chloramine removed) water.

Besides killing bennies I don't believe it is harmful to MJ plants and as others have stated chlorine is essential.

maybe if you added something like Hygrozyme or Sensizyme that would sterilize the water..?? im thinking it would

i use mostly organic and the chlorinated water doesnt seem to affect it. i cant make any guarantees though.

Ive gone the benny route and I just like complete inorganic nutes, someday maybe il go back to it
But for now i get good results without

Petco, aquatics section...AMQUEL, it'll neutralize the chlorine/chloramine in your water if you're worried about it killing your bennies...But the label DOES say "Not for use with food fish", so I'm not sure if you wanna be smoking the stuff. I don't use it myself, but I recieved this piece of knowledge from someone who does to no ill effects. Maybe in a few years his toenails will fall out and he'll grow breasts, or maybe he's slowly growing some deadly cancer in his eyeballs, but for now he's happy.
