question about c02 in a sealed room (venting/scrubbing info)

so im about to aquire a c02 generator, its a propane burner unit that i will hook up to a c02 controller. my current setup is inside a tent, inside a sealed room with mini split aircon.

dodgy drawing shows what i mean.

now im struggling to find info on this as most people talk about venting OUTSIDE the room, but my room is inside the sealed room if that makes sense, and i currently vent into that room, and the aircon reciculates the air.

adding c02 to this, am i still going to just be venting out the c02 into the sealed room from the tent? or will it be ok since the aircon will recirculate it?

basically do i need to change anything from what i currently have it setup like in the pic? i need the filter running for the smell.

any advice would be appreciated, (feel free to draw me a dodgy paint diagram lol)

I assume the triangles are the plants. With a room set up like this I would consider having the ac generator in the same area as the ac as to make more space in the grow area, but really you can have the generator anywhere you want either in out outside your tent. About venting the heat from the generator, I wouldn't concern yourself about that until you get a deeper understanding of the unit. You may never even bother. So put it anywhere you want it will all be fine.

On thing I HIGHLY recommend is get a digital co2 ppm meter, it will make co2 enhancement a MUCH more pleasant experience for you

thanks yeah i was thinking about putting it outside the tent especially for the fact i need the room. i dont have a digital co2 controller but its this one https://www.hydrofarm.com/p/APCECO

should be ok for getting my PPM where i want, and i can still tell how much c02 is in the area by counting the flashing leds lol.

so basically what your saying is i'm going to be getting the c02 of the ENTIRE room (tent and room) up to 1500 PPM instead of just trying to get the tent?

Well ya, your air is circulating anyway so if it is in the tent or out , it will mix evenly.

About your choice in controller, that will get you to the dance but I would get one with a digital read out, that you can read clearly from a distance so you know what you got at a glance, its not too much more than the one you are looking at

yeah issue is im in australia, and the difference is like $600 for a digital one over this lol.

cheers for all the help guys got it sorted, pretty happy with how its all going.

so was a bit worried having the generator inside the tent, but it was that or drill into my roof outside the tent. i've tested temps with an infrared thermometer to make sure and its not really getting hot enough to worry about, also the thing is only on for like 1-2mins max and stays off for well over an hour before the controller kicks it back on. very happy with that a tank should last me ages.

controller goes alright, with how fast this burner works it was to be expected it would go above the 1500 when it was turned on, it seems to go to about 1700-1800 a minute after it shuts off, so i've dialed down the setpoint to be about 1300.

going to get an automatic fire extinguisher and a safety valve for the gas bottle just incase but yeah, looking good so far.
