You should know in 15-30 mins if it helps when lights are on of course… .
And it may not fix it, and I would still find a better solution moving forward… The hose for intake and the fan may be better…
The ambient temp coming in can be a for sure fix but can require the most money to if you have to get an AC like I did… I tried everything and it was only way keep my tent under 95f
Do you mean adding a hose in one of the top ports just to let passive airflow in from the room?

Yeah one from top stretch down to bottom is more light proof then the sides…
I don’t have any more holes in the top the exhaust is coming out of the top lol
If your makeup air is 85f its gonna be difficult to get much lower than where you’re at. It’s not going to be lower than air you’re bringing in at any point. Couple degrees above that is usually about as good as it gets.
Hmm is there any other ways to resolve this issue?

This is absolutely correct, I guess I missed you must have said the room temp was 85f 
Sounds like you need an AC unit to drop the room temp a few degrees.
If you do add an AC, I would vent the tent back into the room also so you are not just pumping your cool air out side…
