H2O2 dosage to treat root rot

Hello You can use 19 ml per liter(of the basic low % from grocery store) but definitely get some more hydroguard, it gets exhausting trying to use hydrogen peroxide every day until its gone. If you have the strong stuff, food grade its like 33% then you would want to start low with about 3-5 ml per gallon until you see how well the roots and plants handle it. But still it will need to be added daily. 👍
