You can load up with the biggest exhaust fan possible, but if your air is humid, your air is humid. The dehu's will raise the temps in each tent, if you're planning on sticking them in there. And not to burst your bubble but the 'damp rid' won't do enough to make a difference. You'll need to fix the humidity in your 'lung room'....that is where the dehu's need to go. And don't sweat the 80s in terms of temp....these plants have been growing in nature long before you and I and they weren't being babied by nature...80 is nothing. Good luck.
