just chiming in here with a question. Whats wrong with wet aspen, wouldnt wet (not soaked) aspen help keep the humidity levels up? I mean, when you spray their tanks you have to spray something, you cant just spray the air, and most things in the tanks wont hold humidity....I have aspen in all my sakes tanks (snake aspen) and I've never had a problem with it being wet, but I could be wrong in letting it get wet........I'm just wondering why it is you say its bad?
