I would have to say yes, the bark has more humidity in the first place and combined with the wet towel, WALA perfect shed! Also you can mist the bark without the worry of any mold growing since it is super resistant to it. Also cypress mulch works good for me as well and it has a better look and feel than the bark IMHO. I have been a lil leary about switching to aspen since it seems so dry to me, i know alot of people swear by it so i am sure i will try it at least once.
