A) Yes true.
B) No. Positive pressure would mean the tent would be exhausting through the intake ports or other places like loose zippers etc.

If you ran positive pressure during flower the smell wouldn't be filtered or exhausted. Your lung room would smell.

Agreed...I'm always fettling with my inlet and outlet fan due to fluctuating temps... know instantly if I've over done it with the inlet as i get a whiff of plant next time I enter the room my cabinet is in, hope this helps
