Booster fan for intake?

My current grow should be done in a couple of weeks, and I plan on making a number of refinements to my home-brew tent. I currently have a 135 CFM fan cooling the light, and a bathroom exhaust fan (I forget the rating) venting the whole tent. Air enters via a passive intake port.

As long as there's a good flow of air through the tent, would there be any benefit in putting am inline booster fan on the intake?
 
only way i see it helping is if your tent is real tight when sealed, otherwise passive should be fine will keep the neg pressure needed for smell control.
 
Depends on size of your tent. 135 cfm isn't enough to do much
I have 240 cfm booster fans. They do not create enough negative pressure to create passive airflow. I just use them to bring in addition air. Adding a booster fan will just increase cfm's.

I get mine from led wholesalers amazon store. $24
