Hydrogen Peroxide is a strong disinfectant and cleaning agent. As one of the active ingredients in many bleach products, H2O2 will kill any pathonegenic organisms living in your water, making it ideal for hydroponics. Although it evaporates within 24 hours, maintenance use will help control pests in the water. Use for sterilisation of tools and equipment to ensure they are completely germ free.
Use at 2ml per L of water. Can be added up to four times a week.
