Here are a few pics of 2 of our rooms, we have another room and a few more isles in each of the 2 rooms I posted but these are the only pics I have. In the last pic the racks all the way too the left are hand made racks that we made for that room, we are working on putting in a few more rows and moving the freedom breeder rack. As for how we have our cages set up, we drill about 5-10 holes on each side for the less ventilated racks for the larger bins and about 4-6 in the front for the ones with more airflow. In the first pic the black hatchling racks have less airflow and hold humidity very well, but we normally put more holes in that type of cage. We use small animal crocks for water bowls, we work with a local pet shop and just order them in bulck. We use newspaper b/c its easy to clean and change, sometimes with cypress it gets too wet even if you dry it out, but we still do use it from time to time normally during breeding season. Aspen is ok I am allergic to it so i try to aviod it but it does work. For picky feeders they get hides. I try to keep the water bowl size smaller bc our larger breeders always flood their cages. We also keep all of our Helix systems on our bottom racks hotter and our helix that control our top racks cooler. But i dont think that would be an issue if you were running one helix for one rack. Racks are great they conserve space and are much easier to clean. What kind did you end up getting?
Good luck with them
