You might soak slow seeds in diluted hydrogen peroxide to encourage sprouting and discourage rot.
1-2 ounces of drugstore hydrogen peroxide in 1 quart of water.
Or 1.5 to 3 teaspoons in one cup.
Since drugstore H2O2 is around 3%, this dilution gives 0.1 to 0.2%.
"Food Service Hydrogen peroxide" is around 20%, so be careful if that's your starting point!
