So I'm making a very dumb mistake lol, sometimes the obvious eludes me. I'm in 3rd floor so noise isn't even an issue for people outside. In gonna try duct from inline exhaust directly to window fan, fma, sometimes I'm astounded by my own stupidity. Thank you for pointing out the obvious solution that I didnt even see. My only excuse is too much personal bs but sometimes im just a flake too lol so coulda been either. Now to rearrange room to get fan in other window
Also noticed the bends in your exhaust duct are too sharp and too straight down. Gentle turns restrict air flow much less.
I used the 3x per minute air turnover rule and the 4x i take hole size (can be 4 different holes) to one exhaust.
Ie: 1 6” exhaust need 4 6” intakes or equivalent size. Can use u shaped bent duct through the low tent holes with black filter foam strapped over each end or black ladies leggings stockings work too for lightproofing.
Upside down “U” through the holes with each end pointing at the floor for the coolest air and good updraft in the tent.
Also point clip fans inside tent up a bit toward the light and try to cause a vortex upward helps with heat removal and upflow.
And i used the house central ac set a few points lower i think like 72 degrees. And yes it will waste some air exhausting outside.
