I just got my Iris Sweaterbox Rack with 32 qt tubs from RBI as well as a Helix and I am SO happy with it. Got it with belly heat as well as dividers. Construction is awesome. I've got 3 of my boys in there right now, and 2 more coming in on Friday. The collection continues to grow! By the way, the humidity seems to be pretty high, but the temperatures are perfect. I DID use a soldering iron and put holes on the sides of the tubs, but it didn't affect it very much. It got really hot in California today, so that could definitely be affecting the humidity. Anyone have some suggestions!
