Proper intake fan

Hi

I am installing a areo system into a 2x 6 x9 closet 108 ft. I am using a 2ft full spectrum flourescent for lights, a 110cfm ultra quiet exhast fan mounted in celing and out the attic. What can I use to pull air from room? could i use a thorough the wall fan mounted in wall in room pulling air in. My question is it needs to be stealth hidden from plain sight the place would be behind a book case on the left side of clsoet door; there is only 2-3 inches from back of bookcase and wall. would that make much less effective? thanks

ya for sure.. u only need a hole for an intake
if u have an exhaust
the air will be pull from the intake
since its the opening
intake must be low

Streetsk8, Thanks for the help. not to be a strickler but puting it behind the bookcase will be no problem?

my first grow, i had my 2 plants behind a bookcase in a closet and they grew just fine.
