That is a good question! Someone with more scientific knowledge than myself might have the answer.

I do use the reptisafe when I make my mist water but I don't think that would matter about mold.

But I use aspen & eco-earth (separately not mixed) and change substrate once a month, (spot clean daily) and I get the inside disinfected and then cleaned and dried out.
