Just to avoid confusion, the 3% hydrogen peroxide you buy at Walmart or CVS is about $1 a pint bottle, is safe to handle and effective for this application. Depending on where you live, hydro shops are probably not open since they're not considered essential businesses (unless your have a brain dead republican governor). The concentrate you are thinking about is probably not the best option for a new grower.I am on my way to the grow warehouse now. Thank u so much
