Yeah that should be cool, you'll probably gonna get a convection effect in your room that way. I'm envisioning the fan will push air up through the center of the room, spreading out then back down the wall to the bottom, constantly moving air around. If I remember right, your venting fresh outside air in through your hood and out to another room or attic, right?
The way my room is set up. I got the 530 cfm fan pulling from the room, thru the hood and out to the attic.
Then I have 2 60 cfm fans running the whole time the lights are on pulling air straight out of the room into the attic, while the box fan is constantly pulling in fresh air through the passive intakes.
The way mine is set up, I'm continually drawing in fresh air from the bottom and then it's sucked out the top. That way I have a constant air flow running from the bottom to the top. There's no stale air and what I would like to think depleted co2 to be had in my room.
Nice upgrade on the room bro. Keep me updated and let me know what you think of the air floor after it's been running for a while.
Peace.
