I was wondering how everyone goes about heating their knobtail racks? I am leaning towards heat cable underneath the tubs? Is belly heat or back heat better? Also, do you guys prefer heat cable or flexwatt?

I have routed some grooves into the backs of my shelves and put a heat cable in the grooves. I find the belly heat more natural as in the wild they will come out of their burrows at night and absorb any residual heat from the ground if needed.

I also use bottom heat. I prefer flex-watt as it is flat and doesn’t require grooves.
