Will positive pressure exhaust a room at the same rate as negative pressure?
      05/22/23 09:57 PM

I have a small grow room, roughly 10x10(feet), not perfectly sealed.  I'm wanting to exchange the air in the room every so often.  I'm trying to figure out if I should blow fresh air into the room from a window through a filtered intake or if I should exhaust air out the window and passively bring in air from the rest of my house.  If I bring air in from outside, I assume the air would positively push out the stale air through the gaps in and under the door.

I'm thinking blowing fresh air in from a window would give me the freshest air rather than what is hanging out in the rest of my house but I'm not sure if blowing air into the room will exchange the air at the same rate compared to if I were to exhaust it and passively bring in air.  Anyone able to help me with this?
