I even use cypress in my BRB enclosure, 80%+ humidity and I've never seen mold grow on it in almost 3 years... think sopping wet at times (BRB's like to be in wetland like conditions when juveniles). cypress is the key to doing bioactive for me with our BRB, that and springtails. haven't swapped out the substrate in more than a year, it's bioactive and planted with a grow light, I don't even remove droppings ... I know, it sounds hard to believe :~(), but it's working and "Ruby Sparkles" is super happy and healthy. Once I am secure in husbandry for our BP's I will probably start a more bio-active approach with cypress and plants and a grow light and see if I can get it nailed down. I rarely add or subtract water to any of my enclosures once they are stable, they are mostly sealed up.
