Hydrogen peroxide....is it safe for direct application in 3% solution.
 

Hiyooo... This is my third posts that I have mentioned my mold problem. I have decided to repot all my moldy orchids with new medium by better-gro. I heard that hydrogen peroxide can be used directly on the roots of the orchids to atleast clean off some molds. Is it safe to spray hydrogen peroxide on the roots in 3% solution?

Yup, you should be fine. I use it for mold in my pots.

just don't store the hydrogen peroxide in anything other than an opaque bottle - like if your sprayer is not completely opaque - it loses it's potency when exposed to light

Wrabbit is right- I only put as much as I think I'll use in my spray bottle, if I'm not just pouring through the mix.
