So I was reading around some forums saying that mixing hydrogen peroxide in water helps root development, and prevent things like mold and pests. At the moment, I'm at about 12 days from seed, planted in ffof soil in solo cups. I watered the plants with the hydrogen peroxide solution about 2 days ago using drug store 3% (which now I'm reading is bad because of impurities). Today the plants look healthier then ever and are really starting to take off, but I'm am worried about what I am reading about the peroxide that I used having impurities and not being food grade. So my question is, if I stop watering with peroxide, will the smoke from these buds be safe? Or am I better off starting from scratch again? All replies would be appreciated. Thanks.
