Water quality reports and chlorine

I did a search, and couldn't really find what I was looking for.

I was wondering if any of you physics/chemistry/botany experts could tell me approximately how long at room temperature, 14 gallons of 60ppm tap water, containing maximum 4ppm of chlorine (not chloramine according to my water report) would take to evaporate? It's sitting in a 25 gallon active aqua reservoir with a couple air stones. Been bubbling away for about 20 hours now.

I need to get a chlorine test kit, but was wondering if that high of ppm (4ppm) would still take about 24 hours to evaporate, or would it take much longer?

Also, my water report doesn't list ANY calcium or magnesium. I like this, as I am used to growing with 0 ppm RO, and know exactly how much I need to add. Is this normal though? I thought that calcium was usually the most abundant.

I am switching from RO for two reasons: 1) time and cost producing RO taking too much time and money due to waste water and 2) 60 ppm out of the tap is absolutely insane NOT to use... especially if it doesn't contain any chloramine!

I'm using Cyco nutrient line growing in coco/perlite, but add mendo honey and mykos. I believe I still need active microbes to process molasses?
Don't want to kill them with chlorine.

I know a little bit of chlorine is actually essential to plant growth, but does anyone know the acceptable range to not kill microbes in coco? From what I've researched it seems to be around .5 ppm chlorine or less won't hurt microbes. Can anyone confirm this?

Also, does anyone know of a good chlorine test kit? I've seen the pool testing chlorine strips online, are those accurate enough?

Simple carbon filters remove chlorine. For fluoride and other salts you need RO or ion exchange resin. With the ion exchange you don't have waste water.

Yeah you can get a simple fish aquarium canister filter and fill it with activated carbon and use that to remove all the chlori e fron a large res of water. Or a better choice is to add a dual carbon prefilter same as used in a ro filter just with no ro membrane, to a tap for immediate use or a storage res.

There's a few reports on youtube, and on the Dudegrows (scotty) says that chloramines in water has little effect on bacterial colonies, If using an inoculant to start a culture, I would use water that does not have chlorine in it.. I can say for sure, wetting a compost pile with city chlorinated tap
does not slow it down.

If you are concerned about chloramines, I used to use sodium thiosulfate to dechlorinate the water.. Should be cost effective vs. RO. However a carbon filter will remove the chlorine, and is even cheaper than Thiosulfate. I had dechlorination verified with a test after it was ran through my filter. Stoped using thiosulfate after no chlorine was verified in zero tap.

Stopped using a filter, after letting water "sit" in a 50 gallon trash container to let chloramines evaporate off when growing with natural ammended soil.

If you're worried about not getting enough microbes, brew up an AACT.. Apply once a week. I always have one going,

This is no biggy ...!

I leave the water to vape off overnight or better 24 hours

as my plants actually use the excess chlorine

IMO, use 50/50 but you may need to play catchup later

adding calmag in early bud

good luck

Use it straight from the tap. The need to off gas is another forum myth. Used to live 1/2 mile from a water treatment plant where levels are at their highest ppm. No problems (see my avatar). Now....if you're into making this thing as complicated and confusing as you can....got for it.

Water report doesn't list Ca or Mg? Strange. Was it tested for those? Collect rainwater which is the best.

My well water is as hard as it gets and most of it comes from bicarbonates of Mg and Ca. I'm talking about a TDS of 839 ppm!

Ca is an important secondary element (not a micro). Dyna-Gro foods have Ca.

Dolomite is rich in Ca & Mg, etc.

Rainwater in North America, even in very remote locations, now contains glyphosate. Active carbon filters (before your r/o filter) remove glyphosate.

No it doesn't, not that glyphosate is harmful to begin with, it isn't. Burned down 10 miles of a strip with 35 gals. of mix the other day. Once these chemicals hit the ground they aren't magically airborne.

I harvest rainwater and water priceless tropical fruit trees in a large greenhouse weekly.

Glyphosate use in the United States increased from less than 5,000 to more than 80,000 metric tons/yr between 1987 and 2007. Glyphosate is popular due to its ease of use on soybean, cotton, and corn crops that are genetically modified to tolerate it, utility in no-till farming practices, utility in urban areas, and the perception that it has low toxicity and little mobility in the environment. This compilation is the largest and most comprehensive assessment of the environmental occurrence of glyphosate and aminomethylphosphonic acid (AMPA) in the United States conducted to date, summarizing the results of 3,732 water and sediment and 1,018 quality assurance samples collected between 2001 and 2010 from 38 states. Results indicate that glyphosate and AMPA are usually detected together, mobile, and occur widely in the environment. Glyphosate was detected without AMPA in only 2.3% of samples, whereas AMPA was detected without glyphosate in 17.9% of samples. Glyphosate and AMPA were detected frequently in soils and sediment, ditches and drains, precipitation, rivers, and streams; and less frequently in lakes, ponds, and wetlands; soil water; and groundwater. Concentrations of glyphosate were below the levels of concern for humans or wildlife; however, pesticides are often detected in mixtures. Ecosystem effects of chronic low-level exposures to pesticide mixtures are uncertain. The environmental health risk of low-level detections of glyphosate, AMPA, and associated adjuvants and mixtures remain to be determined.

Apparently the half-life of glyphosate, in clay soils, is up to 22 years.

LOLOLOLOLOL!
Now that's funny.
Billed as the "safest pesticide/herbicide ever invented" and it's backfiring horribly. Asbestos was also billed as the most amazing substance for thermal protection, you see where that ended up. (Took a few years for humans to figure it out though, quite a few)
I'm guessing you don't know much about glyphosate? How it works? How it affects humans? If you did, you wouldn't make statements about it being safe. The EU did not renew licensing for glyphosate this year. No more roundup in the EU, despite monsanto's best efforts.

Bully for you. Doesn't change the facts of the matter.

A little more 'light' reading on the facts coming out about glyphosate

Environmental-Health-2016 said:

Current models and data from the biological sciences predict that:

1. 1.
   Glyphosate and GBHs disrupt endocrine-signaling systems in vitro, including multiple steroid hormones, which play vital roles in the biology of vertebrates [21, 22, 24, 62]. Rat maternal exposure to a sublethal dose of a GBH resulted in male offspring reproductive development impairment [21]. As an endocrine-disrupting chemical (EDC), GBH/glyphosate can alter the functioning of hormonal systems and gene expression patterns at various dosage levels. Such effects will sometimes occur at low, and likely environmentally-relevant exposures. Contemporary endocrine science has demonstrated that dose–response relationships will sometimes deviate from a linear increase in the frequency and severity of impacts expected as dose levels rise [19, 63].
   
   
   
2. 2.
   The timing, nature, and severity of endocrine system impacts will vary depending on the levels and timing of GBH exposures, the tissues exposed, the age and health status of exposed organisms, and other biotic or abiotic stressors impacting the developmental stage and/or physiology of the exposed organism. Exposures can trigger a cascade of biological effects that may culminate many years later in chronic degenerative diseases or other health problems. Exposures leading to serious complications later in life might occur over just a few days to a month in short-lived animals, and over a few days to several months in humans.

Oh yeah, really nice and healthy stuff.
Fortunately, the amounts in rain water are a mere pittance, compared to how much builds up in seeds and oils. It passes from the seeds and oils into the animals eating them. It also passes in the milk to their young. Yum!

"The EU did not renew licensing for glyphosate this year."

That is an outright lie. Or you are just talking out of your ass. They extended it, just for less than the proposed 15 years. The Monsanto haters need to at least do some research before they spew bullshit to people undermining all the real reasons to hate Monsanto. It makes you look like a propaganda using fool when you state things as fact that are not. Like saying that it causes cancer, there are multiple independent organizations like the WHO that have tested and found it is NOT A CARCINOGEN when used as intended. The EU study is not even testing Roundup in an applicable use, it is literally taking the raw chemical and trying to make it cause cancer, as we all know almost anything causes cancer if u try to make it cause cancer, aka the sun, your microwave, cell phone and a million other SAFE PRODUCTS.

I have an idea:

Put a thin layer of activated carbon on the top of your pot, that way when you water, it will remove the CL!

europa.eu said:

1. End June 2016: End of the provisional extension at EU level of the active substance glyphosate. Commission extends approval of the substance, under certain conditions.

In all, the EU's assessment of glyphosate has taken 3 years, involving public sector scientific experts from EU's agencies (EFSA and ECHA) and national authorities in all 28 Member States.

27 Member States agree with EFSA's conclusion on carcinogenicity (Sweden was in favour of another classification).
What is the final decision?

The Commission adopted the extension of the current approval of glyphosate for a limited period until the European Chemical Agency (ECHA) has concluded its review - since Member States failed to take responsibility (no qualified majority was reached at either the Standing Committee or the Appeal Committee).

What this means is they're allowing it, while they wait the final ECHA decision. This is definitely NOT a 15 year renewal, my statement is accurate.
(edit: You're getting pretty heated up about this. You're aware the more a person believes a lie, the greater their emotional response is to the truth, right?)

"The EU did not renew licensing for glyphosate this year. No more roundup in the EU, despite monsanto's best efforts."

That's a direct quote from you, which is 100% not true.They renewed but only for 18 mo when they will decide whether to renew for longer or not. It is still on sale, will be for at least 2 years even if they decide to not renew. You are a bullshitter, its actually pretty funny. Had yoiu said they failed tor renew for 15 years your statement wouldn't have been a total lie, just the part about it going bye bye.

"The European Commission has decided to extend the licence for glyphosate by 18 months, after member states failed to achieve a qualified majority in favour or against the executive’s proposal." (from late june)

Thats a quote directly from the committee that made the decision to extend the licence, but not for the desired 15 years. Got any more straight up lies to tell people, it was renewed, for 18 months? Telling people that it is gone in EU and they removed the licence is a straight up lie....id love you to explain how it is not a lie.

How emotional you are about bashing a company that u have to make up straight lies about them is pretty funny, and how u project your own emotions on others is even funnier. I hate Monsanto, but i hate people bullshitting others even more. Keep it to the truth or you make the people who actually know something about Monsantos wrongdoing look like crackpots like yourself.

Roundup is not the problem, the problem is Monsanto's vice like monopoly on GMO seeds, please do some research.

Yep, I missed that I'd thrown that in there, got cut off when you quoted it the first time. Oops. Wishful thinking on my part, here's hoping the ECHA gets it right.

I'm not heated at all, actually laughing a bit. You're quite worked up over it. GMO is evil, glyphosate is nasty. R/O grows the cleanest cannabis, with the fewest issues. Get over it.

love when people admit to being liars after accusing someone with something like this

More like my response to your bold faced lies.....

You must hang out with liars a lot.
I added a phrase I shouldn't have, not a big deal. Got any more paragraphs you want to throw up on the page?

Curious to why growers do this, I have read thats its called 'gassing off' but im a bit in confused to why it wants to gas off in a weed reservoir and not the water pipes it comes from?

Without a link to a credible website and without some cherry picking with all the usual faulty testing at propped up organic wacko sites, I aint buying it and am living proof as are millions of others that your premise is bullshit. Microbes feed on glyphosate. Here's proof that this is just another internet Monsanto scare tactic without any basis in truth.
