exhaust fan
    #785096 - 07/12/15 02:31 AM (2 years, 9 months ago)

I'm in the planning stages of my first grow in close to 20 years I'm starting with a small SOG set up. The space is just under 20cf. I was thinking of using a 70 CFM bathroom exhaust fan that I had in my mushroom green house. I'm pretty sure it will move enough air. My concern is that it won't handle the static pressure of a carbon filter. Will this type of fan work or should I be looking for other options?

If you're concerned about smell¿ then no.  Otherwise that's plenty of movement when it comes to FAE. 

As far as heat goes its going to depend on what you're running

Dude she isn't as young as she use to be.

o/ hey mudafuka. I've read that the lowest CFM phresh filters do not restrict a noticeable amount of airflow. I guess you only need to account for the static pressure on larger fan / filter systems.

@hawk why wouldn't it be enough to scrub the smell? An air change every 20 seconds would still allow scent to build up?
