Is a Split T8 too Small for an Adult?

[Dev_DeCoste]

So I have enough money for a T8 finally. I want to get it a divider for it so I can house two BPs in there, at least while they are still hatchlings. I'm wondering if with just a weaterbowl and 2 hides if 24x24x12 will be too small once full grown? What I would like to do is save up a little longer and get 2 of these RHPs. The guy over at AP said he would install for me if I had it shipped to them. I was going to have one of each of those on both sides. I figure with that, I probably won't need belly heat right?

So the 2 questions are will that be too small and will 2 RHP eliminate the need for a UTH?

Thanks!!
