Can I pull air from and vent out into the same room if the bedroom has a fresh air exchange?

Every situation is different. Only way to know is by testing it and keeping close eye on temps, humidity and ideally co2 levels.
Probably need to run a dehumidifier in the room.
Its not ideal, but workable if temps stay stable.
The obvious issues are humidity in the room, the temp slowly rising and rising each pass through the tent, the co2 gradually decreasing which can have a huge effect on your plants health and vitality.

Right on. I keep my house relatively cool at 67°f. And the temperature in my tent right now hang out about the 74-75 degree range with my R.H in the 50% range.(I'm still in veg). Does this calculator tell me what I should know?

Not sure on the calculator as it says it cant tell you how much plants use.
Im not a guy that uses co2, I just exchange air enough but as a precaution and for my own curiosity I bought a co2 meter a few years ago to read the ppms of co2 in my tent. It was higher than I expected.
Anyway point been get some sort of tool that measures co2 so you can see if your too low. I think ambient air is maybe 400 and in the home it can often be higher, do check my numbers, been a while since I looked into it.
I picked up a little meter for £40 which was made in Germany (might not of trusted it had it been made in china)

I like to use the Autopilot data logger in each of my rooms. they are awesome. See what your CO2, temp and humidity do over time.

Some good points. I don't think the Co2 would be a problem, bedrooms are not sealed (round doors , light fittings etc) so there would be some draw.

Your probably right, just something to keep in mind really.
I once came across a site which gave info about exactly how much air exchange was achieved passively through floor gaps, door cracks and key holes ect.. It was really surprising just how much. Alas I never saved it and have never been able to stumble across it again. :cry:

If you have hot air rising and therefore spreading across the ceiling then you have cold air circling up from the bottom, drawing air in were it can. Obviously it wont be ideal but if teenagers can live in a bedroom then it must be ok for plants..haha.

I have a 3x3 in a small room (8x10)
I the winter when it gets cold I vent back on the room to keep my temps up. My led conversation worked too good.

I don’t notice any issues. When you go onto the room and do your daily chores. Leave the door open.

Thanks for all the input everyone. I've got a co2 moniter on the way, and Given all the input, I'm gonna go for it and keep a close eye on my ppm. Really watch my temp and r.h as well. Again, really appreciate the help and perspectives
