Adding Nutrilife’s H2O2 is a great way to oxygenate nutrient solutions in reservoirs. A plant’s health and vigor rely on the roots getting enough oxygen, because the roots of a plant need oxygen to convert carbohydrates into energy. H2O2 adds this important element to nutrient solution, effectively “powering up” preexisting feeding regimens. It can also be used to preserve fresh cut flowers and for cleaning reservoirs, drippers, and dripper lines. IN STORE SALES ONLY DUE TO HAZARDOUS SHIPPING LABEL.
