2 tents one room... advice please

I'm looking to add a 2nd tent to my room. One for veg one for flower. I have a 4×4 and a 2×3 running LEDs i have a 12000 btu portable ac running on auto to dehumidify the ROOM down to 32% i have it at a constant 68°F to account for my light Temps bringing internal temps to 76°F day/68°F night. Currently 4 weeks from harvest. Im dialed in there.

So the question is this... how do I go about adding the 2×3 veg tent to the same room and maintaining its OWN internal temperature? PS. The room is roughly 10×10

be careful of light pollution for the flower tent

I have is 2 tents, the flower tent has constant ventilation so all I've done is add a piece of ducting from the flower to the veg and another 4" inlet to keep it negative and draw away any smell, I'm using a led so heat is not an issue, but I've a fan in the piece of ducting for when I do need it, as mentioned above you need to watch for light transfer the light can travel a good bit along ducting you need a bafle box or a loop/spiral in the ducting.
