Totally correct.
This is why I'm so loving the RHP's: They mimic the sun and allow for a much more diverse temp gradient for the snake to really choose what will be most beneficial to them at any given time during their day or night.
This is also the reason why I want to change over the balls who are in cages and why I am working hard to get all of my balls into cages (the ones who are big enough!)
I LOVE RHP's!!!!!!!!
