1 on 10 off. I clone the entire space then change water and clean with bleach/rinse after. I use tap I let it run a full day before adding clones to let residual bleach plus city watr chlorine evaporate. I get roots on my hardest to clone, og kush, in 3 weeks though. I get roots faster on others but for eaxmple I am 8 days on this run with nothing showing
just FYI city systems don't use chlorine. They use chloramine, which is more stabilized. You can no longer break down and evaporate off the chlorine without using vitamin C first.
This is a GOOD thing when it comes to cloning. Filtered water is pure but open to pathogens. Chloramine is not. It's chemically treated to kill ecoli , which hurts both us and plants.
You can save yourself that day and not aerate.
Also at 64f, your water carries tons of oxygen. Peroxide may be redundant or unnecessary. Not trying to be a know it all, just sharing.
Appreciate your success story. Cloning can be tricky. It tends to be 0 or 100% for most folks, or at least for me.
