Was concerned about that as well. With proper airflow it'd prevent mold i hope. Worst case, i have to take doors off my cage and remove it. Hopefully that doesn't happen though.
Swapped out the Golden pothos which didn't do very well after re-potting. Put in this Japanese Aralia for it's large leaves and sturdy stems to climb. It has been doing great for the past two weeks. I also had to replace the bromeliad which got heart rot. I put in another pothos I had and it's doing great. The jade plant really wasn't serving much of a purpose, so i replaced it with a split-leaf phylo to retain more water droplets after mistings.
