Odor control suggestions?

I have a long narrow garage, the way its set up you can see in the photos. Im about to go into flowering in 5 days (this is my first grow) and Im worried about the smell leaking out of the garage. I have a charcoal filter for the flower tent but I dont think its going to be enough to kill the smell and the tents arent air tight at all. I can smell my veg tent on the outside from the cracks of my garage door already.

Space is limited cause the car will be parked in there still.

I was looking into building a 2" wall with a door and holes for air vents. Thats a lot of work and its a town house Im renting, going to have to take it down when I leave.

Someone was telling me today that hanging vinyl curtains might work? but that might take a few layers of them and the smell between the top of the curtains and the ceiling might leak out.

Does anyone have any suggestions which might be best and easiest?

Can't really contain the smell in a leaky room...man I'm curious...WTF are all the boxes on the wall for and just what do those naked stick girls really look like

own a clothing company, garage serves several purposes.

I think Im going to try 1 of these curtains out. Seems easier and cheaper then building a wall. They claim to get air and odor tight

2 x 2 beams, 1/2" x 4' x 8 x 12' wallboard and flat white paint. White Paint has the best reflective qualities and does not cause hot spots that burn your ladies.
