Do I need co2? Garage grow

Due to kids and traffic in my house, I have a stealth garage grow. The garage is attached to my house and is insulated, but it is not ventilated.

My tent has an extract fan and carbon filter that exhausts into the garage. But there is no way of fresh air getting in or out of the garage.

Should I add some kind of co2? Any tips for growing when temps in the tent get to 90F?

Thanks

Yes.
I can show you pics of what happens when you exhaust into the same area that your tent is in and dont have a fresh air intake.

Oxygen rich co2 depleted air get sucked into the tent and chokes out the plants that need the co2.

At first it looks like nute deficencies. Which you chase around. Then they then suddenly they crisp up like toast...lol

Hmm, a garage that's air tight? You keep a Ferrari Daytona Spider or, another million dollar car in it?

It has air exchange....

I might consider a roof top air vent - for the extract fan. Done deal then.
OR
Add the gas and don't worry about 90F temps.....You'll still need to exhaust. Because you'll be better suited to run an environmental controller with that gas...

Questions?

I wouldn't say "air tight". There are no vents or exhaust so I guess the only air exchange is through cracks in the garage door.

The problem with a roof top air vent is my house is two stories and there is a room right on top of the garage.

What would be good co2 options?

I've had 3 runs in the garage and let's say they all have turned out a little less than optimal. I just now thought it might be the lack of fresh air causing issues.

How big a space are you working?
What lighting? Be detailed please.

I can answer better, once you answer mine.

pick up a c02 meter and skip the guesswork. place it just under your canopy for accuracy.
you know what they need at their leaf surfaces and go from there. fresh air supply would do it too likely
c02 is even more necessary as the growing space temps rise causing faster metabolism requiring more
c02 than normal. you should control your atmosphere to avoid more guesswork later=losses
good luck
