Hydrogen peroxide is very fast acting and dissipates readily into oxygen and water. It's great for dechlorinating a water source. 1 part HP reacts to 8 parts chlorine.
May be used to disinfect a water source. Good, concise information on using HP with plant nutrients is inconclusive. Hydrogen peroxide is a HAZARDOUS MATERIALS product and can only be SHIPPED BY TRUCK ONLY. Read warning label and directions before use. Wear protective clothing, gloves and eye wear. This is a strong oxidizer and can cause burns.
