I like all that info thanks a lot, I do have the Availability to put them in seperate rooms if I'd like. I just thought it's be easier to have them in the same room. But your points are def making me realize it'll be harder then I bargained for. Thanks a lot!
No problem

It can be done in the same room and I dont want to sway you from getting the cham you want the most. That is what is important. Just want to let you know that its going to be a juggling act

Not everyone can juggle. I can a little. Can you?
If you are going to try it some things to consider trying.
Keeping the cages apart from each other.
Using a high wattage bulb for the low land species to try and keep the ambient temp just around its cage higher while not getting the ambient room temp too hot for the jacksons. You will want to make sure the bulb is not directly on top of the cage or the cham may get burnt. Set it hanging above making sure the basking site is correct but the extra heat is being distributed to the other sections of the cage making a good ambient temp yet still providing the cham with temp gradients.
Cover three sides of the jacksons cage with some painters plastic or whatever you like so it keeps the humidity in better. You could use a humidifier near its cage, use a fogger that goes off here and there throughout the day or just mist his cage down more. You do want to make sure its drying out between mistings or you can cause problems that way.
It is possible to get an appropriate night time drop for a jacksons while still keeping a low land comfortable.
If you do want to try it that way I suggest setting up the other cage before you get the cham so you can do test runs and make sure its going to work out for both.
Hopefully this helps out and you get the cham you want while making both of them happy regardless of what species you decide
