I am currently using coconut substrate and I am thinking about going back to aspen like I had it before. I think aspen is a bit cleaner, but I couldn't get the right humidity level with it. I have changed the cage some and I am thinking I could get the level right now that I covered the whole top except for the lighting area.

I will try it either this weekend or next weekend, but do I have anything to worry about by switching substrates?
