i grow in a cab. about 71.5" h 59" w and 20" d

the cab is broken down into different areas. i have supreme ventilation (so i think) but i want to increase the airflow to make sure there wont be any possibility of mold due to the fact that im sog'n and place anywhere from 8-16 small single cola plants in a 40" x 20" space (flower chamber).

i have a 6" exhaust fan in the flowering room. the exhaust and the scrubber also hooks to the mother and daughter chamber.

i want to get a bigger fan (my intake is currently a 4") and possibly route more air under the canopy.... will my bigger intake create smell problems and other problems for my exhaust fan?

this is something like what im talking about.


would the fan on the intake being bigger have a bad effect on the exhaust?

or you do think i should ALWAYS have a bigger, more powerful exhaust than my intake?
