T10 enclosure divider for baby ball python?

[Homebody]

I am planning on getting a baby ball python in about a year, and I was wondering about the size of the enclosure. I want to get an AP T10 for when she is full grown, but I can't get multiple enclosures to increase the size of a starter tub as the baby gets older. Would I be able to use the divider to keep the baby in one half, then remove it as she grows? Also, would the use of a RHP sized for the entire T10 make the baby overheat because she's only in one half? Sorry if this is a newbie question, just wanted to ask.

I think a divider can make the enclosure an appropriate size, but I think that size RHP will make it too hot. You could hold off on the RHP and use a UTH instead if your room temps aren't too low. UTHs aren't expensive.
