I have most of the screen on my glass tanks covered with plastic wrap, and then duck tape over the plastic wrap (mostly for aesthetic purposes). My bedding is 50/50 cocoa fiber/cypress mulch then I place sphagnum moss around the water bowl and along the edges of the hides and in the actual corners of the tank. I'm in southern California where we are usually fairly dry and my tanks have now been staying between 60-70% with a misting every couple of days.
P.S.
When I run my CHE in the winter I up my misting to once or twice a day and it usually stays fairly constant, but I do add more moss when they are in shed.
