I've been reading that I can put hydrogen peroxide in my water to keep bacteria and algea to a minimun. How much and is there any risk?
Thanks

no more than 1.7ml per liter of the horticultural grade 35% h202, is what ive heard round these parts..

when all your roots are healthy and tip top, I would lower your application rate of h2o2 to 1ml per gallon..
