if anything get two exhaust fans. I added one exhaust one intake and now my exhaust cant keep up with my intake.
if I was to redo my grow box I would get two fans exhausting into one single duct and run the duct outside so no smell in the house.. or at least run it up to the attic. because you want negative pressure in your box so that you are sucking air from the out side in and not pulling to much in and having a positive pressure thus forcing air out places you don't want forced. esp if you have a carbon filter for smell the only way it will work is with negative pressure.. so if anything just put one exhaust fan and see how much it sucks through and if its not enough drill some small holes in the bottom or close to the bottom of the box. But that's all I got to say Happy growing!
