I recently purchased an AP 18 slot 1860 rack and the humidity is hovering right around 44% according to my accurite. Any tips on getting the humidity up another 10% or so? I currently only have 7 of the 18 spaces occupied, would it be worthwile to put water dishes in the 11 empty slots or would that not be enough to do anything? I don't have any holes in the tubs. I was told by the woman at AP (can't remember her name of the top of my head) not to bother with the air holes unless the humidity got too high. My largest female's eyes just started clouding over last night so I'd like to get this taken care of in the next day or so so she has a good shed.
