Need help deciding on ventilation set up

[Cavemanej255]

So I have a room that’s roughly 9x11 that I use to grow in. It has 2 tents that I run open and a closet. Total the room has 6 plants all getting ready to flower. I need to get ventilation set up in the room. I have plans of possibly ditching the tents and using the open room at some point but for now It’s tents and closet.
what would you guys recommend for ventilation. I planned on getting either 1 ac infinity t8 or 2 ac infinity t6’s. Both setups with carbon filters. I don’t necessarily need to pull air from the tents as I have fans circulating air around. It’s more for odor control and supplementary temp/rh control. I will have either set up vented up through the ceiling and into my attic.
Let me know opinions or any suggestions!

That will cause black mold growth in the attic when it's cool/cold outside. Warm moist air will condense all over the attic.

What sorta lighting will you need to cool with your setup?

Have you considered just running sealed with AC and CO2?

Will making a piece for the window to vent outside/ out the window be better? I’ve considered running sealed but how would I deal with the smell?

So i guess my question now is regarding the routing of the exhausting ducting. I calculated the area of the room and figured out CFM needs.
is a ventilation system still effective even tho there is no exit to the outside of the room for the duct work?

Yes. Same way, with carbon scrubbers running in the grow area.

No. If the exhaust is recirculating over time the entire room will heat up, get humid, and be depleted of CO2. If you have cold/dry temperatures outside and you go in and out of the room frequently you could pull it off but its not advised. Either exhaust to outside, or run sealed w/ AC + co2.

My setup is multiple tents, each with their own thermal and humidity controls, their own fan and filter, and they just circulate the outer room air if and when they need it.

I then have the outer room thermal and humidity controlled as well, with an exhaust/intake fan setup, and a dehumidifier.

It works great, but only because I control that outer room and keep it supplied with fresh crisp dry air a couple degrees cooler, and at a lower RH than each of my tents' upper limits.
Hope you get it figured, good luck

Where do you vent the outer rooms exhaust to?

Straight outside out the bedroom window, intake brings in fresh air from the same window. Just a board with two 6" ports with a fan on each port.

I am not worried too much about the visual part of it as I am a licensed grower, and I am not worried about cops or anything, so that may be something you have to consider.
