Curious about ppm amd the water i have.

My plants are grown in natures living soil.
my tap water is 300ppm
I also have a ton of water from my dehumidifier at 20ppms

i dont understand ppm all that well, ive tried ‍

your water has 300 parts per million of buffers in your water. that's about average. what it is you want to know? is it good for your plants? Probably, but a water analysis would tell you what the 300 parts are. if doing organics, I believe you really want to know if they use chlorine or chloro mine and how much.

How Long Does it Take for Free Chlorine to Evaporate From Tap Water Entirely?

Surely many aquarists have heard that chlorine will leave faucet water after some time. But exactly how long does it take for tap water with Chlorine to be safe for fish? Can the clearance be

looks like they use chlorine

How long does it take to aerate chlorine out of water?
Depending on its levels of content, the evaporation time for chlorine from tap water can be estimated: 2 ppm of Chlorine will take up to 4 and a half days or around 110 hours to evaporate from 10 gallons of standing water. Ultraviolet light, circulation, and aeration will speed up the process dramatically.Jul 27, 2018

There should still be more, so far were not seeing cal mag and ph and at about 50ppm of a total 300ppm.

There was only two pages in the report and I didnt see any other numbers.

You will find it somewhere or webchat/call the company and ask them where it is online. The two parts you show are for contaminants lead and chlorine not cal mag etc and ph giving total ppms.

So far i dont see a problem but if others in your area use it for potted plants you should be fine too.

Say you panic you can add 50% distilled or ro water to weaken its values or just source clean water and stop using tap.

Theres a lot of plymouths, if its Uk you can check with local growersxor the growshop, if its usa you prob have access to ro water if your state waters not desirable to others.

I feel like it should be ok.

@2Hearts here is what the water department in Plymouth MN told me:

In 2010 the average hardness was 22.2 grains per gallon (380 mg/L or ppm)

Calcium Hardness= 212 mg/L
Magnesium Hardness= 168 mg/L

The ph of the water averages around 7.6

I have been using the water collected by my dehumidifier and it seems to be working, but this is my first grow so I dont have anything to compare it to. The only nutrients I have going is natures living soil. Do I need that calcium and magnesium from the tap?

Ok well bad news is you live in a hard water area and they use some water softening which i think accounts for the small amount of sodium.

Before explaining what does your water taste like? Im guessing its got some taste and a slight off taste from the softening, prob not that great tasting.

Your water isnt really suitable by standards but you can test it impatially on a plant full grow if your a good grower, noobs might struggle with other stuff still to get a clear picture but idk your grow skills so you can judge there.

Fuck calmag again wow! Its a never ending subject, try to think of water cal mag as dissolved solids, they line the taps as scale (good question do you get lime deposits and scale on taps and cooking stuff?). The calmag in fertilizers is often highly absorbable like calcium nitrate and totally different to water calmag which is not so absorbable and like a limestone rock breaks down slowly. In fact we use lime in soil, the reaction of acid breaks it down, lime neutralizes it and we have a buffer against ph. The process is slow and wont produce much calmag unless you live in a chalk soil area in which case you use a fert with less calmag because the soil is waaaaay over limed. So no you never replace calmag in tap with fert calmag, pretty dumb idea prob toxify your plants with calmag eventually but if you used hard water you would find an appropriate hard water fert to compensate tbe imbalance.

But fuck that, you got dehumid water and can grab cheap ro shop water maybe even rain and when short dilute tap water by two thirds with dehumid water. Better to find a solution. Hey what are growers in your area doing, any making the water work? Not just cannabis, what are other potted plant people doing or saying.

So negative on the water but certainly investigate more dont be totally put of by it as everywhere is different.

I was under the impression chlorine wasn't good for an organic grow and thought those guys tried to remove it first. could you elaborate more on chlorine. thanks
