chlorinated tap water for plants

This is an interesting video.

absolutely lovely video. thanks for your contribution. seems microbes dont give a fuck about the residual chlorine.

also found this study just now


they conclude that chlorine in water had very little effect (not significant) in microbial composition and diversity and enzymatic activity even in extreme doses for tap water like 10ppm. again, in tap its at most 2ppm generally. its worth a look imo.

Municipal water is 100% fine for plants. You can also acclimate your plants to a particular type of water supply. IMO the only real "concern" is just having an idea how your tap water reacts to nutrients being added to it, and what your final levels are of things like calcium or possible heavy metals. Lots of city waters have quite a bit of rock dust in them, too.

ok this can be a more acceptable concern you may have too much bicarbonates too which will alter the ph of the medium in time. so yeah there are other concerns about tap water but chlorine is so far below the list. tap also can have beneficial elements like calcium and magnesium in healthy amounts and ratios too.

i posted this thread after i saw a thread about “is chlorinated water ok for my plants” once again. it should be clear that chlorine is ok. and i understand some growers choose to avoid it because they feel that its better for their plants and i respect. i can accept what people do with their plants is their business. however science is still science.

A small amount of vitamin C powder takes care of Chlorine/Chloramine very quickly. I don't think it's harmful enough to cause any noticeable differences in plants, but the cost of ascorbic acid is negligible for me and it's a part of my routine now (plus, there are benefits for plants too-they seem to love organic acids). I use it to dechlorinate bath water and water for my turtles too, it's kind of awesome.

How much vitamin C powder do you add per gallon?

Lets talk about the fluoride in the municipal water supplies, and the all the weird estrogen\hormone blocking/endocrine disrupting pharmaceutical chemicals that they can't seem to filter out, to which there are no real regulations for, and keep recirculating and building up to high levels..

How does all that affect your plants?

Or is that only in the US..

Generally speaking I don't think it does, but I could be wrong

sorry man gay animals exist in nature and i can confidently tell you that drinking my tap water didnt alter my testeosterone levels at all so i dont think there is any of those stuff you are worried about in there.

What Pharmaceuticals Have Been Found?


The U.S. Geological Survey (USGS) first reported the presence of pharmaceuticals in streams across the U.S. in 1999-2000. In the largest study to date, from 2007-2012, the USGS and the EPA examined the presence of pharmaceuticals in source water and treated drinking water across the U.S. (Furlong et al., 2017). In phase II of the study, samples were analyzed for 118 pharmaceuticals, with 47 pharmaceuticals detected in all source water samples at a median concentration of 14.2 nanograms/liter (ng/L = parts per trillion). The most frequently identified pharmaceuticals in source water were lithium, sulfamethoxazole, metoprolol, carbamazepine, estrone, and hydrochlorthiazide. In treated water, 25 pharmaceuticals were detected, with lithium, bupropion, metoprolol, carbamazeprine, and cotinine most frequently detected at a median concentration of 10.6 ng/L. Treatment processes appeared to be effective in reducing concentrations of most pharmaceuticals.

i understand your concerns but ppt is so extremely low, i mean we are talking about nanograms if we go into nanogram stuff i am guessing even rain water will have lead and shit in it. it will catch impurities as it falls down.

when you look deep enough you will find problems for sure thats what my ocd taught me. when we start to worry about nanograms nothing we put in the soil as amendments are safe either. manure, guano and other animal byproducts contain heavy metals, vegan fertilizers do probably contain residual pesticides and stuff.

in that sense i am reminded of this saying that its not the poison itself which kills its the dosage. so parts per trillion i am not that worried about but ofc if it makes you feel better and have the setup you can further reduce the contaminants by using ro, i just wouldnt invest in it for residual chlorine and/or pharmaceuticals.

but again gay frogs always existed even before humans and watering your plants with tap water or even drinking it will not alter your hormones. i mean its very very extremely unlikely that it will at least.

Speaking of nano, I doubt they are using comprehensive tests to detect the amount of engineered nano particles floating around in the water supply either.. Who knows what kind of nano water filtering tech they are testing on populations of people these days? Its almost like you need nano tech filters to filter the nano particles, lol.. Its every where, in food, and probably even your toothpaste.

I just stumbled on this.


So if you do not want to take the time to watch this, I just want to highlight that using tap water does carry risk with it. It does effect microbes, although it might not effect all of them, it definitely does effect some of them. Chloramine and Chlorine are can be harmful to your soils. They are designed to kill micro-organisms so if they are in your water, they will effect your soil biology.

I get that these may be thin but the root of it is that if you are aiming to achieve the best results you can, tap water is not going to kick it unless you are testing your water on a regular basis. Yes you can use tap water and get good results but you will get better results from using water that is chlorine and chloramine free.
