    Dont spray it on plants. Its used to control pathogens in the res, not mold.

    I agree with BUDS... don't spray your plant with h2o2.
    You can use lemon water, but I'm not sure of the mix ratio.
    I've heard zero tolerance works very well for pm.

    H2O2 is an oxidant and works as such. Oxidation is not good for everything. For more info see "Rust".
