Okay basically i have a questions that hopefully someone can answer.

I am running 2 grow tents in a sealed room with aircooled hoods that are hooked up like this:

carbon filter --- > hood --- > fan --- >

the air is exhausted out through the top of the tent back into the room. The fans are 530 m3/h (one per tent).

I am not using an intake fan, its passive.

So my question is, if i released co2 into the room, would it move around or would it just fall to the floor and stay there? I know that it is heavier than air, but then again I am moving 1060 m3/h in that room. Would it not be sucked up into the tents through the passive vents?

Before i do anything else to deliver the co2 i would just like to know if this method is viable. I have a controller so yes i will be able to dose the room correctly (to a degree). My question is just whether or not it will be available to my plants as I'm not releasing it over them and even if i did it would be sucked out of the tent pretty fast no?

Thank you all!
