The small amount of chloramine in tap water won't hurt your plants. I've been watering plants with tap water for decades and we have chlorine and chloramine in the water. I water straight from the tap. People make too big of a deal out of chloramine and chlorine. Some companies even add chlorides to their nutrients.
There have been studies done by the agricultural departments of numerous universities about chloramine and chlorine and their effect on soil microbiology. The studies concluded that both chloramine and chlorine while making a slight dent in the microbial population that there is no long term effect and that the populations of microbes bounced right back as they are extremely resilient.
I’m with you on that one.
I was updating my thread last night after just filling up my 20L container in my bathroom and hauling into my grow room.
I then mixed my nutes. Updated the thread with pics etc.
Then pH’d said nutes and fed to my plants.
I’m with
@xtsho on this one. In 10 years of growing I only ever left my water out to “dechlorinate” a few times before I stopped doing it altogether.
if you’re source water at home is good enough to drink and has an EC value under 0.5EC I would highly doubt it’s going to do any harm to your plants if you don’t offgas it.
the reason you allow fish tank water to dechlorinate or use an additive such as SEACHEM PRIME is that chlorine kills the bacteria responsible for the nitrogen cycle that is found in fish tank filters.
