Air intake question

I'm working with a large shed type building that's about 12 feet wide x 14 long x 14? Feet high. I only have 1 passive intake window, whitch is a out 3 feet wide and 30 inches hight, double door windows located near the top on one wall.
I only would be opening it anywhere from 1-4 hours per 24 hours. Would this be enough air in/outtake for my room? I also have an ocslating fan in the as well.

You would do so much more by adding at least one inline fan that actually pulls fresh air in while the lights are on, I keep mine on 24/7. Based on your dimensions you gave, you have about 2,400 cubic feet of space. The "rule of thumb" is cycling your air completely every 5 minutes would be a minimum, 2,400/5 = 480. A decent 6" fan can move about 450 cubic feet a minute, so that would be the minimum I would consider using. Personally, I recommend going WAY over board when it comes to moving air as heat will be your biggest enemy indoors. I can cycle the air through my room twice a minute if I need to, and sometimes I do...

One of the problems I think you may have with just open windows is no circulation. I would use a fan or 2 just to move the air around. The other maybe id there is a male plant floating around somewhere you may get accidental pollination if you dont filter the intake.
Also if its not a "legal grow" all those plants are going to STINK.

So legal grows don't stink?

When it's legal it's not a "stink", it's the best smell in the world.

All legal bro, smell is not an issue, plus no one lives around to smell it
