And gatekeeper, I don't want to be a gadfly towards you personally, but I've seen some of your advice (adding what was it, kool-aid mix or something, to your water to make the buds taste like kool -aid) seriously unless you are SURE you should be VERY careful what you post.
Bleach is a solution of 6% sodium hypochlorite... Peroxide is simply a fairly unstable molecule that quickly breaks up into nothing but water and oxygen gas (2 H2O2 -> 2H2O + O2) and leaves no residue.
Guess which one I personally would rather use on my plants?
While bleach has a place in your grow room, like sterilizing pots and cloners and the floor, and even a quick rinse (no more than 10% v/v) for suspect seeds, I keep it away from my plants.
