Stacking tubs without a rack?

[RichsBallPythons]

I still think that some snakes are going to get more heat than others and that will not work. The only way I could see that it would work is if you have some sort of set up where the backs all go against a strip of uth (flexiwatt) at the back.

I currently stack them in my QT room since theres no room for racks there.

I stagger when i stack where the UTH isnt all on once side. The above tub warm side will be above the bottoms tub cool side.

Heres how i have them in QT.
