Should I be concerned about the fact I'm using city water. I'm comfortable drinking it, but I can smell chlorine in it. And I'm not buying bottled water for my plants. Thoughts? My outdoor plants were fine and indoor but this grow, I don't want chlorine killing my organic bacteria as I have a total organic grow going.

If your city water is chlorinated with chlorine, it will mostly volatilize just sitting out over night. Chloramine does not dissipate as easily.

I grow organic soil and I don't use distilled or RO water. I think the buffer capacity of soil helps deactivate the chlorination chemical. When I add microbes during the grow, I'll used distilled water for that, but it amounts to a few gallons per grow.

I bought a chlorine and chloramine filter that hooks right to my hose bib

My town uses chloramine

I still fill my water buckets a day early so they are room temp before using

While I'm new to growing cannabis, I've grown indoor plants of all types, including orchids and tropicals for sixty years, and never had problem with the chlorine in city water. I lived 19 years in South Florida and grew a massive garden of tropical plants, all watered from the city line. Like I said, I'm new to cannabis, but we're talking about a hardy plant here, and I'm wondering if the concern over chlorine is valid. I'm about to start my first outdoor grow and the local tap water is fine to drink, but I can smell the chlorine. If this requires an inline filter for the hose, I'll get one, but I'd like to hear what the experts have to say on this matter.

IMO, the only time you need to be concerned is if there is a high concentration of chlorine in the water, or if you live in a place like Flint Michigan that had major water quality issues or potential contamination in the reservoirs.

Been using tap water on my grows since I started in September, and haven’t had any issues with my town/city water.

Hell, even when I drain my pool when I close it down, or because we had too much rain, the plant life where I drain the water has never suffered, so who knows.

A carbon filter and/or some ascorbic acid (vitamin c) will neutralize chloramines. However, unless you're brewing aerated microbial teas, the small amount in your city water source should not be a problem with your organic grow.

Few facts.

1. The maximum allowable amount of chlorine/chloramine in drinking water in Canada snd the US is 4ppm.

most sit around 1ppm

2. chloramine cannot be off gassed like chlorine and will stay in the water even with weeks of aeration.

3. Chlorine is a micro nutrient, not saying that you should be adding it but thats the truth.

4. 1 gram of ascorbic acid (vitamin C) will neutralize 1ppm of chlorine or chloramine in 100gal of water.

tldr: there is no need to even consider chlorine or chloramine unless brewing teas. Even then at 1ppm it is only a consideration imo

I thought real RO water would have no chloramines and any Chlorine would've been filtered by a GAC before distribution?? I only ask because i use RO water for that reason of contaminants.

The first thing I do after I water the plants is fill the watering cans. That way, most chlorine that's in the water will dissipate before the next watering. That said, I've watered a lot of plants (not necessarily cannabis) straight from the tap without a problem. It also warms the water to room temperature, which can be important.

Exactly what I do. I have quick disconnects on it but I just leave it on my hose.

That’s a good idea! I never take mine off because of the plastic threads and just not wanting to damage it, I do need to buy a new one though this one is getting close to a year old, probably only 1/4 of the lifespan but I like to have spare stuff on hand lol

Friend I was looking at your plant photos and noticed that you have a lot of leaf bronzing and leaf toxicity. If you started with clean RO water you wouldn't have that problem with your plants. I hope you don't mind me trying to help.

What makes City water bad for cannabis is the water treatment program they use that is designed to cancel the Cation Exchange Capacity. The reason why is, so heavy metals won't end up in the drinking water. Lead, Zinc, copper, iron, mercury, and other heavy metals become available when the water has a high hydrogen content. Water treatment over-rides the hydrogen content by raising the hydroxyl content making all heavy metals nonconductive. Without treatment, babies, the elderly, and sick people would get poisoned from heavy metal exposure over time.

Types of heavy metals commonly found in water include manganese, lead, arsenic, chromium and copper. Google

When you start with clean filtered water compared to tap water the results are night and day difference. Using RO or rainwater will give all the plants their full potential compared to using treated tap water. If you can't afford a RO filter just get a rain barrow and catch-free clean water.

You mean a rain barrel I assume?

I’m in the city and use my rain barrels, all 4, for my garden and outdoor plants but wouldn’t use then for my indoor plants. To many things get into the water. The amount of things floating and living/dying in the water is enough to make me cringe sometimes. 😝

But that’s here and how I feel about it.

What a load of bullshit this is. Where do you come up with this garbage.

Do yourselves a favor and ignore this crap. if some of you want a deeper explanation of water treatment ill go through it tonight after work. But most of you can find the info easily online.

time to start clearing up some of the bad info here. Its one thing to speculate and give an opinio, its whole nother thing to present it as fact when its false.

they buffer the ph to prevent things like flint Michigan where the water is acidic and erodes coatings on the piping that will end up eroding the pipes after and leech heavy metal into the supply. In the case of flint lead pipes

There are max levels for acceptable drinking water.
