chlorine

I recently read a very interesting article about chlorine and chloramine levels in drinking water, relative to average houseplants. I will attach a link at the bottom of this post for anyone interested in reading it in detail. To summarize, the levels of chlorine and chloramine in drinking...

0.01 grams (10 mg) per gallon of 52-58% CalHypo powder will give you 1-2 PPM chlorine (example ~0.3 grams per 30 gallon reservoir) 0.002 grams (2 mg) per liter of 52-58% CalHypo powder will give you 1-2 PPM chlorine (example ~0.28 grams per 100 liter reservoir) I've used the search function on...

i dont know why some growers and mostly some new growers are obsessed with chlorine levels in tap water. chlorine in tap water is at most like 2ppm. which would not even penetrate into a cm of soil. i water all my outdoor plants with tap water and they all live happy. the reproduction rate of...

So I’ve tried using H2O2, 50% strength solution, at a concentration of up to 0.2mL per L, which has not been effective in getting rid of white mold growing on the Coco. Surprisingly, grape seed extract has proven very effective at removing visible mold. Although GSE has worked for visible mold...

Apparently vitamin C can be used to break down and get rid of chlorine / chloramine in tap water. This sounds like a better choice for me than using R/O water. At my local drug store they had pure vitamin C powders in different forms- ascorbic acid, calcium ascorbate, and sodium ascorbate. Does...

I use tap water and I grow in coco. Should I worry about dechlorinating my water if I use microbe brew? Should I dechlorinate all my water to keep microbe life alive in the root zone? If it helps I'm using GH Flora series as well. Thank you!

Since I started using tap water, I have noticed the start of what I thought to be calcium/magnesium+nitrogen deficiency with the brown spots and yellowing/dying lower leaves. Luckily I was able to harvest that before too much damage was done. But as I am now seeing it happen on another plant...

Hello, Just wanted to attach pictures of my file (hopefully you can see it) for comparisons of all the different bennie products out there and there cfu/spore counts. Now, take into mind that more strains are not always better and that Bacillus amyloliquefaciens or Trichoderma harzianum are...

So I’m running a 30 gallon rdwc system and I was wondering if my tap water would be okay to use? It has a ppm of 197 and EC of 395 which I’ve heard isn’t so terrible. The only problem is I know for a fact my hard city water contains small amounts of fluoride and of course chlorine/chloramine...

I just started to make some experiments with Calcium Hypochlorite to keep my res clean and dead (sterile). I bought ORP meter which should reveal the oxidation (killing) potential of the water. I tried different measures in different times. The goal is to find out how often and what dosage we...

Like the title says. Here is what I'm doing - took a distilled water gallon and dumped it (after reading no need to use distilled) and filled it with tap water. Tap water reeks of chlorine with a 7.5+ pH, but ppm is 140~ which I understand to be pretty decent for tap water. I also read people...

Adressing the Claim That Chlorinated Water Harms The Soil Microbiome & Harms Plants One of the most prevalent of the many unfounded claims made by members of the Cannabis growing community is the claim that Chlorinated water has a detrimental effect on plant health, primarily the soil...

Hello everyone, I have a quick question and was hoping to get some advice. I'm currently growing 3 White Widow plants that I stated from seeds about 3-4 weeks ago. I've just been using tap water to water them. The Ph is at 7 and the TDS meters reads 80ppm. At about 3 weeks I thought it was time...

Been using same Britta filter since December and recently got a new one. The old one mightve been letting chlorine + others through im not sure. Looked kinda like sulphur def but I was feeding +/- 1tsp epsom every watering for mag/sulphur up until week ~5 of flower. Then stopped to give gypsum...

I ran out of water while trying to transplant two small plants from a solo cup to a 3 gallon container. I only had enough water to transplant one plant. Do I still need to give my plants chlorine free tap water (water sitting at room temp for 24 hours)? Or can i just give them straight ph...

I have previous "experience" growing organic in soil and I am about to switch to Hempy/Hydro with Perlite, Vermiculite or Coco. As most will usually do when they grow, they leave tap water out for at least 24hrs to let the chlorine evaporate. In an organic grow, I can see the chlorine really...

Hello all, I have been using distilled water throughout my whole grow so far just to be safe at least while my plants were still young. I found on a previous grow (my first, one plant, turned out male) that the plant didn't seem to like my tap water that much. And I know that it is actually...

I've got a few questions arisen about water quality, filtering, chlorine etc. I've been filtering my tap water in an 80L/21Gal bin using an aquarium filter (ceramic, carbon & sponge) designed to 100L/26Gal. I let this run for a couple of days in an attempt to take out the chlorine and...
