Co2 in grow tent

I run a sealed room but I’m helping a friend setup a grow and he’s bought a grow tent. How do you use co2 in a tent if you have fresh air coming in?

Step 1: Install a mini split air handling unit inside the tent. Or, cut a big enough opening in one of the walls, and push the whole tent up against a window already fit with an AC unit hanging from it, right where you made the opening, and tape it all up.

A few other options; stuff an inefficient portable AC in the tent with the hoses running out of the ventilation ports to the windows, or hookup a chiller to an external reservoir and pump liquid water/coolant from that res into a radiator & fan unit hanging inside the tent.
Keep it all sealed up.



Step 2: Hang a small propane or natural gas c02 generator\burner inside tent, or hookup bottles to a regulator and run the lines in. Plug into a co2 controller or program your timer, and let it rip. Use way less c02 in the smaller tent space than if you were gassing the whole lung room out.

You don't put anything inside the tent.You run the tent in a sealed room, sealed meaning it's not activly vented. The room your tent is in is called the breather room. You vent the tent into the breather room to exchange air. The breather room you climate control with a window ac, portable ac, or mini split. Also in then breather room you add the co2, from a burner or tanks.

To control smell, create a 12 hour dark cycle, ect.. I mean I guess you could put all that crap in a tent, but what size tent we talking? If you're gonna seal a tent and not vent it it'll need a/c and a dehumidifier and a co2 tank, so I guess you could put all that in 1 half of a 10x10 and grow in the other half, seems dumb tho..

If they’re growing for personal use in their home ambient co2 is plenty, no need to seal anything. Humidifier with hose set outside the tent for veg, exhaust fan set low, good sized dehumidifier in the tent’s room exhaust fan set to high in flower

You could hook up another smaller tent and put most the bulky equipment in that one, and connect both tents together with ducting so it actively recirculates through both of them. If you insulate the tents better you'll be saving on electricity as well as the c02 by having a smaller space.

Suppose there are pro's and cons to doing it either way. I did forget to mention its probably not worth it though, lol.
