Hi guys! I have a room in my basement where im trying to make myself some medicine. The problem is that the room is very poorly vented, it just has one vent in the wall so should i use it as an inline or outline vent? Any suggestions on which would be better? Bring in fresh air or take out the air that way? Any suggestions are welcomed.
Can i sub the fresh air with Co2 and use the vent as an outline since i wont be getting fresh air in, in this case?

I had the same issue in my basement. I ended up doing some carpentry to take in fresh air at the bottom of the wall and exhaust through the vent at the top. It solved my problem.

Could Co2 replace the fresh air? Isn't that why we want fresh air in the first place?

I could drill through the wall and install another vent but i dont know how and dont have tools for it (actually dont know what tools to use). Having some outsider do it is too risky..

I would cut out an exhaust vent into the basement (in the wall of the room) and use the existing vent as a passive intake. You risk burning out your fan without good airflow, intake and outtake vents are necessary.

Don't bother with co2 yet, learn how to use the 300 ppms that mother nature gives us for free before dropping a grand on a ductless a/c and an atmospheric controller. Better/cheaper to cut a hole in your wall IMO :)

You should learn. I didn't know how to install a water heater until mine started leaking and I couldn't call a repairman (I'm growing in my basement as well:))

I guess i just have to learn how to install vents going through concrete walls huh? :) Or possibly find some mary-friendly installer guy...

I thought it was a "room" in your basement, like with studs and drywall, lol. Is the door made out of concrete as well?

well its a cold room for storing potatoes and other vegetables so no drywall in there. And the door is wood.

hmmm... I'd suggest cutting passive intakes on the door with carbon filter and fan blowing out the existing vent. Or say fuck it, seal up the vent and get a ductless a/c and a co2 system.

Problem is you have to deal with the heat, and you can't do that with a vent fan if you only have one vent.

I agree. however if the walls are concrete blocks, they have 2-3 hollow spots, a good hammer at the hollow will blow a hole in it w/out too much effort.

lol was just going to say the same thing as above< the tools you need for putting a hole in the wall are a big hammer and some duct tape lol

Unless you know what you are doing, best not compromise structural integrity of a load bearing wall by punching holes in cinder blocks. I built my room and did all the framing myself. No load bearing walls to worry about. This could be a problem. I have always said that this hobby is won in the planning phases.

Actually there is a concrete block wall leading into my hotwater boiler room and its not a load bearing wall, maybe i could just punch a hole through there and lead air out that way. Which will leave me the already existing vent for fresh air intake! How does this sound?

or reverse it so you get your air from the boiler rm. the pilot light from the boiler will raise your CO2. and during summer months, the air from the basement might be cooler than fresh air from outside. down side would be winter when the boiler runs,that air may be too warm/dry to be good for intake air. also consider the smell, it might be better to vent out so you dont stick up the house.
either way you run the air,sounds like you got your orignal problem solved.

Thnx guys for helping me out! One more thing tho.. Is a normal cpu fan enough to bring in air or do i need some bigger fan for that?
