How much 35% H2O2 do I use per litre or gallon.

  1. I have a jug of 35% H2O2 (hydrogen peroxide) that I want to be using like yesterday. My problem is that the retards over at Grotek equipped this bottle with a ridiculously complicated measuring chart. What I want to simply know is what is the MAXIMUM amount of 35% H2O2 I can add to my reservoirs. I am growing in soil and a hydro setup if that makes any diff. Thanks in advance duders!
  2. For what do u need to use hydrogen peroxide?
  3. 2 tablespoons per gallon is used for 3% so probably want to start off at about 1/2 a teaspoon per gallon.

    Hydrogen peroxide is beneficial as an addition to nutrient feeding programs at all times. It feeds the good aerobic bacteria and kills the bad anaerobic bacteria. It also introduces radical oxygen atoms which oxidize elements, making them more available for the roots to assimilate. I apply 3% H2O2 at a rate of 30ml/gallon to the reservoir. The plants show no visible signs of stress afterwards, which indicates that it was not an excessive application.

    Sprouting Seeds: add 30ml 3% H2O2 to 1 pint of water. Soak the seeds overnight.
    Insecticide Spray: combine 250ml 3% H2O2 to 1 gallon spray mix.
    Fast growing container plants: add 30ml of 3% H2O2 to 1 gallon water.
    Hydroponics: apply 3% H2O2 at a rate of 30ml/gallon to the nutrient reservoir.

    not sure if that's true though. The part where it kills bad bacteria and feeds good. Many people think it just kills all bacteria good or bad.
