Do you think the majority of commercial hydroponic green house growers are wrong. They use chlorine at 4 ppm or higher added into the pipesfeeding the irrigation spray heads so as to m not waster chlorine in the reservoirs through dissipation. I recommend 2.5 ppm as an initail treatment reduced to 0.5 ppm as a residual level of chlorine. Tap water is allowed to contain up to 4 ppm at customers faucets. Thousands of growers of mj use tap water without any removal of chlorine. 10's of thousands of people water their houseplants, flowers and lawns with water containiing up to 4 ppm of chlorine. Plants can tolerate extremely high anounts of chlorine. they ac not tolerate chloride. Fish can tolerate high levels of chloride but not chlorine. Salt is sodium chloride. Plants can not tolerate high levels of chloride Caphese.
Hydrogen peroxide is a much stronger oxidizer than chlorine. It is much easier to cause problems using hydrogen peroxide than to use chlorox bleach.
Too many myths in forums and on the web. Have you heard of Pythoff. It is sold in two versions. Professional/commercial made with chloroamine or hobby grade made with chlorine.
