A/C for flower tent while running CO2

We're doing a small run outside of our normal rooms to try a new nutrient line and I'm going to have to flower in a tent. The idea was to recreate the conditions the plants would have in our dedicated rooms including c02 in flower.
I have a couple stand alone a/c units but those would require venting outside the tent and most likely pump out the c02.
I'm running hps so will definitely need to cool the tent.
My only idea so far is to attempt to isolate and duct in the input/output from a window a/c run outside of the tent (but not in the window because winter) but this seems stupid and clunky
How do y'all run c02 in your tents while managing temp?

I think you’re best bet is to do a small tent in a corner of your sealed room, intake and exhaust should help keep it at the same levels and temps of your sealed room. Tents are great, but you can’t really get em air tight.

We are fullll to the brim
I know a tent won't be air tight, just looking to keep it cool without straight up exhausting c02

really curious to hear some good answers to this question, I am thinking about getting a 4x8ish tent to test some genetics in, and want to recreate the conditions of my main flower room as closely as possible, I thought about maybe getting a dual hose portable a/c but I dont see how there would be room in the tent with trays and everything. another thought I just had was getting a tent, pushing it against a wall, and then getting a small cheapo minisplit like a 9k or so and screwing it to the wall studs though the tent fabric, could probably run the lineset out one of the ducting holes. no idea what to do about dehumidification though. I think tanked co2 would probably be okay in that scenario but the only experience I have with tents is as a pop up drying room for some outdoor like 10 years ago, so I don't really know. Maybe someone with more tent experience could chime in?

What about using a dual hose a/c and cutting the tent so only the front of the unit is in the tent?
Or constructing a frame, cutting a hole, and mounting a window a/c?

I tried to figure your challenge out for long time when I started growing. I grew in a 2x3 box and used co2 to combat the heat. With co2 plants are good to 85+ degrees so with led lights and the driver outside of the tent and you run the lights at night that's a good start. The tent in a cooled room too. Best AC option for a tent is what @trambles suggested. A window banger built into a custom frame....easily made out of 2x4 studs. Like framing a wall. If its installed right it cools and recirculates air inside the tent and co2 stays in. You could water cool the tent with a chiller, fan and some sort of water /air exchanger (Ice Box) connected to a chilled reservoir and a pump. No air leaves the tent. Water has to be about 65 to keep tent 85. Lots of stuff but definitely doable and it works. Good luck!
