Hydrogen Peroxide 50% 1L
Hydrogen peroxide, or H2O2, is a strong disinfectant used to keep hydroponic setups sterile. A solution of H2O2 and distilled water can be added to your water on a regular basis as the hydrogen peroxide will evaporate within a few days.
Be sure to use extreme caution when working with H2O2 as contact with the skin or eyes will cause severe burns. Due to the hazardous nature of H2O2, it cannot be shipped by courier and is for collection only.
