RHP Size/Wattage?

[Dmurphy95]

Heyo all, finally coming alive in this place again now that we have finally moved and started to settle into our new home in South Carolina!

And what do you know, my first post back in here is a question. XD

To make it simple: I have come to the conclusion that I need a RHP for Mopani's enclosure.
I'll be buying two, since I do plan on using up that other "half" of the one big 6 foot enclosure Qizil used to live in for another noodle when we eventually move into our "final" abode in about a year or two. I only need info on one since both "sides" are the same length and width.

Reasoning is literally because, even with all the other things I've tried, including BIG UTD's, and UTD combos, I still can't get the temps to where they need to go. At this point humidity is perfectly fine, and it will continue to be considering where we live now.
But the higher ambient temps just in general mean we now have air conditioners going all the time...And I kind of just have to accept that this is my last/final option now for these dang Boaphile cages. X'D

Now, for more in-depth things: The enclosure I have is the 6322D Combo Cage from Boaphile Plastics. Which, as mentioned, can separate into two separate smaller enclosures.
The separate halves are both 3ft by 2ft by 1.5ft.

I am looking for help in understanding what preferred size, and definitely wattage I would need for them to have the temps get up to where they need to go: Specifically with the hot spot being 90 Fahrenheit.
There are of course the RHP's Boaphile Cages sell, but I've heard very good things about the Reptile Basics ones too.

Anyone got input on this?? X'D I am going into this completely blind and would appreciate the help! I already did some research on both but I don't know where to go from here, or how to determine what I need!


(Sorry this is so long~ X'3)
