I've read a lot of posts about C&C cages. It's the cage I'm going to be using, I've built mine. But I'm not sure how to keep it warm. I have two 250W CHE's with 10 inch domes and the ReptiTemp 500r. My cage is 3x2 and a loft. The loft isn't a full cube up it's a little less than half way up, only 6 inches up (a little less than half way up).
