BP's don't need to be cooled for breeding.

I wouldn't go with a Hydrafarm for a rack, when they fail they run wide open. Hot melted plastic tubs - yuck! And that's the best that will happen, worst is you could also end up with a burned snake.

I would look at mid-range t-stats like a VE Hobbyist or VE100, Herpstat, Ranco, etc.
