This is what I am thinking of doing, mainly because I have been having really big drops in humidity a few hours after misting. I used the pre-bagged stuff and didn't add water to it (I was hoping just misting it would be enough) but I think once the wet surface layer dries out there is no mositure so after misting I will get a spike up to like 80% but once the water from the misting is dry it drops to like 40%. I would just go back to the aspen if it weren't for the fact that the aspen couldn't get the humidity high enough. So I think this is still the better option, I just need to figure out how to keep the humidity stable. He never did much cage exploration before this (spends most of his time in his hide anyway) so I don't think it will bother him too much long term. He already seems calmer about the whole idea, now it is just an issue on the husbandry side of things that I need to solve.
