Fresh air in air-conditioned room

I have a grow tent that I plan on using in a bedroom. Because it is hot year-round where I live, I will have to use an air-conditioner in this bedroom. The grow room has a fan that takes out air, plus some vents at the bottom, and I have done my homework to know that this circulation is adequate.

However, since I plan on keeping the door to the bedroom closed, and with the air-conditioner on, the bedroom -- and thus the grow room as well -- won't be receiving any "fresh air" from outside of the house. Is this a problem?

The fan in the grow tent will exhaust a lot of air from the grow tent but I don't really have a way (right now at least) of bringing in "fresh air" from outside of the bedroom; it will only be the air-conditioned air from within the bedroom that will enter into the grow tent through the vents at the bottom of the tent.

And if I really need to somehow get fresh air from outside of the house, it will be costly due to the hot weather in the region.

Any help would be really appreciated, and my apologies if this seems to be a rather naive question.

If you have central A/C or even a window shaker, then you have new air coming in. Did I understand you correctly? Are you thinking your plants are trapped in the room and the air is gonna run out like people trapped in a mine or something?

No, I don't have central air. I live in a developing country and most homes just have single unit air-conditioners scattered throughout the homes (or not at all). Half of the unit is outside, and that brings in air from outside into the room; the other half, the operational half that is affixed to a wall in the room, is inside the room. So I guess this would be considered air from the outside of the house but since it is filtered through the air-condtioner, I'm not so clear if it would be "fresh air"?

Hope that clarifies my concerns a bit. Based on what you just said, though, it would seem that I don't have to be worried about this.

You are fine... Unless the a/c is running in closed loop or recirc mode you ar bringing in fresh air. The Filter just filters out large particles..

I'd keep the a/c set to around 70 and you shoudl be fine.. It's gonna be hotter in teh tent than the bedroom so play with it until you get your desired temp..

Good luck to you..

You would need some kind of a heat exchanger. What a heat exchanger does is - it brings in fresh air that gets cooled by the outgoing cool air.

Coversely, the outgoing cool air gets heated up before it exits the room.

In effect, you bring in the fresh air into the room without heating the room as much and making the air conditioner work overtime this way.
