I've been growing with mixed results for a while now, and I have decided to upgrade from my micro-grow (150w HPS scrog - 2 plants per DWC 5 gal bucket) to a 600w HPS (1 plant per DWC 5 gal bucket). I know I need to upgrade my ventalation situation. I have the following questions:

1. If I use an air-cooled light, what size blower would I need to ensure that the heat from the 600w is exhausted from the room?
2. If I use another fan to extract residual heat and stinky air, can I just use a blower that will extract the square footage of the area once every couple of minutes? What about the overage to cover a carbon filter? (I'm a bit fuzzy on which math to use....) The room is about 168 ft2. Do I just divide the 168 by two then add 20% for the carbon filter?!?

Thanks so much for any advice! I didn't want to waste money (and noise) on overkill, but have had heat issues in the past..... I also can't have stinky air running amuck!
