CO2 in a small tent of 60x60cm - what to choose?

I have two tents 60x60x160cm and think about trying CO2. I think about a 2-5 liter cylinder with a night switch or CO2 bags hung in a tent.
The room with tents has 3x3 meters, there is no ventilation in it, so I lightly open the door to 2 cm.

I can't make a closed circuit in the tent because it will be too damp and too hot in the summer. So there is only the option of normal ventilation, such as in most crops. My lamp is a LED quantum board 110W.

Do these methods make sense and will not be a loss of money?
There are a lot of different strange devices for the CO2 generation, but it's hard to get reliable information. Sellers always want to sell their shit, the same producers, regardless of effectiveness.

For now, I am not even able to determine how much the cost of such a CO2 application will be for one tent in one cycle 3 months.
The cheapest are small CO2 cylinders for the aquarium.
I read a lot about CO2, but I still can't determine what solution will be best.

The canisters will work in a sealed environment as long as you have a Co2 controller. The Co2 bags are a big scam.

Tent setup with inlet and extraction fans kind of defeat the purpose .

I came up with such an idea.
My room has dimensions 3 x3 x 2.8 meters.
I am curious about the price of CO2 for such volume, counting for one cycle. Hoses supplying CO2 from the cylinder would lead to tents, but the gas emerging from both boxes would also fill the room (in a lower concentration), and then it would be sucked again.

Would it cost too much to maintain the right PPM level in tent?
I air the room through the minimum gap in the door. Basic ventilation must probably be in any cultivation room.
The level of humidity is quite large in my tents, it does not cause mold, but more %, the plants will not stand anymore.

Would removing the oxygen from the grow space using an oxygen concentrator work? Instead of recirculating the oxygen compress the gas into a tank and ditch it somewhere else.

Kinda pricey to get all that equipment. You can’t remove too much O2 or it can kill you! Your not really trying to remove O2, your trying to increase CO2.

That won’t help your humidity issues much, remember also, you will need to raise the grow room temperature for CO2 to be effective. Quite honestly CO2 is more for large scale grows, not small tents. At best you’ll only get a few grams increase in yield, probably not cost effective.
