@INK ARTCERRATED
that is only 15 cubic feet ...........u can use a simple 4 inch booster fan

that fan does 100cfms your area is only 15cf so this fan will cycle the air in your room 6 almost 7 times a min ( that is over kill but it is good )
any of the 4 inch carbon scrubbers should do u just fine to control the smell

now your intake for this u want it to be a 8x8 inch hole for passive or u can get a 2nd 4inch (go for a weaker one a 70/80cfms )

the first 4inch fan is metal blades so it can spin faster with out chance of it breaking .......the 2nd is plastic blades so the spin is lowered on them reducing the amount of air it moves
those 2 fans should make your grow area have negative pressure control the smell the temp and increase the plants size tho fresh air and co2 from in the house (co2 lvls indoors can be 300/450 ppm compared to outside of 100/150 ppm in woods/farmlands )
the intake u want it low so the air coming in is cool .........it is best to have it as far away from the exhuast as u can this makes the air move over the plants and keeps it cycling around them and fresh)
the exhaust is simpler u want it at the very top above the light if possible (u want it sucking out the hot air/used air )
as for CFLs get rid of them they will not do u all that well and as u add more to increase the lumens/coverage the heat they make increases .........LED light
if u got money say something i can link u a nice light

if u do not money i can link u to a generic LED that works well for me with Auto (never used it on a photo)

if u get the light plus the fans .......this whole set up can run off one breaker in the house u still have about 7/9 amps left so should do u fine
