I have no problem keeping heat in my cage,averaging 84 degrees, in fact I think it might be on the high side 89 degrees usually mid day, in the evening it averages lows of 76 degrees. I'm having issues with humidity which maintains at 60 or so unless the fogger is actively working.My fogger goes off twice a day and I try to spray once a day so my two girls have droplets to drink. But I've had limited success retaining humidity for more than an hour or so. I heard from a reptile store owner to use moss to help keep an even release of humidity. I know I need to give the cage a day a week to dry out to prevent fugus growth or respiratory infection. Is moss a good idea? Do you guys have experience with this? How much moss is ok? and what kind? I'm looking around on sites now and see a whole bunch, some have dyes which seem like a bad thing, even though my green trees don't touch the ground often. if anyone has any insight I'd love to hear it. I promise to post pictures of my girls olivia and ophelia soon.
