I thought I'd post pics..
Here's the BP rack. I use heatmats on rheostats now, but once the incubating is done I am swiping the Helix fro that and running flexwatt on this thing. Then I will just buy another thermostat for the incubator next year The light on top is strictly for lighting purposes when I am cleaning/looking at snakes; Not a heating element! I have shredded aspen in the females' cages because they are recovering from breeding/egg laying; thought they needed some extra spoilage
Usually the lower tubs have their hidespots over the heatmat, and another hide on either side.. they are smaller snakes, and the mats will not slide under the sides because the tubs fit too tight.. hard to explain.

Corn tank is to the rack of the right. Aspen shavings, not pine.

And my BCI cage. Aspen shavings again; model horses all over it because I was dusting their nearby shelf
