I am building a new rack tomorrow that will have a lot of space for tubs. My question is that I have noticed that the hot spots for Rosy's and Ball's are very close. Around the 88 degree range. So if I was to put the Rosy's on the top shelf and the ball's on the lower shelves, would they be able to live in the same rack? I know that Rosy's need less humidity, so I figured if I only keep small bowls of water, and lots of ventilation holes in the tubs that it would keep the humidity in those tubs down. What are ya'lls thoughts on that? Thanks for any input.
