i'm looking into purchasing a rack for my small very small collection of BP's lol, but for the time being i have them housed in tubs so to cut down on space i was wondering if anyone has had any success with stacking tubs on top of each other, would each heatmat cause a problem for the tub underneath it.

if so would it be possible to rotate the way they're stacked for example the bottom tub has its uth on the left side, could i put the uth on the right side of the second tub and then stack it on the bottom tub and essentially heat the cool side of the bottom tub with the uth from the second tub. heres somewhat of an illustration of what i had in mind, basically stacking tubs with heat mats but switching up their positions to essentially heat the air of the lower tub.
