I have a Fluker's digital Hygrometer/Thermometer, and the temp is currently ready at 86 degrees F. It "feels" just as humid is with the coco fiber, if not more, and the humidity doesn't seem to drop AS FAST as it used to. Kinda got used to misting at least twice a day, which seems excessive, but I'm not sure how else to keep humidity up. He didn't have a problem with climbing before he got sick, with the old coco fiber, and the humidity would be reading the same.
The funny thing is, AS SOON as we put the styrofoam backing for the terrarium in, he started climbing all over it. He climbed to the top, moved horizontally over to the glass above the temp/humidity gauge, and about a minute or two later he actually FELL to the ground - I'm fairly sure he didn't jump down, but he did end up getting a few of his pads to stick on a leaf and slow his fall ever so slightly. Still, he fell pretty hard into the soft moss, I've never seen him fall beforeIt couldn't be "traumatic" for him to climb again, could it?
