Sterilizing soil-less mix with boiling water and H202
I have an open bag of perlite sitting in my barn that I want to use for this season's veggies.
I'm trying to evade using the microwave/oven to sterilize the soil. After I get my soil-less mix together, could I just throw boiling water onto the soil and stir it? Or add a little hydrogen peroxide to the boiling water to sterilize it?
