Who uses hides in their tub/rack systems?

[Sasha2]

I have a homemade rack with 4 tubs. I have hides in all of them but notice they stay in the heat where the hides are and rarely move from them.

I wonder if I removed the hides they would be more willing to regulate.But then I think they would also be more stressed.
The room is not cold either in fact Im worried because its been very hot in that room, 80 plus yet they still mostly stay in the hides(im very tempted to turn off the heat mats).
I use those plastic plant water catches as hides and cant really fit another on the cool side. I do have humid hides on the cooler end for the smaller bps though and they do use them but prefer the plastic things.

I assume they are smart enough to move away from the heat if they start to overheat, even if it means being on the exposed side of the tub????
