...according to my calculations (Calculator:), that comes to 675 cubic feet. I will be having 2 - 600w HPS lights. I already have an 8,000 BTU AC Window unit at one end of the room which is keeping the room more than cool right now, although I only have one of the lamp hooked up at the moment. What kind of fan do I need? I plan on using a carbon filter for the smell and just running ducting through a tarp that is dividing the room. Im not quite sure how fans work (inline im assuming I need), but I'm wanting to have the carbon filter on one end of the fan and ducting on the other...is this how these fans work? And last, what size carbon filter do I need?

Thanks to everyone!

Peace

Hey col,

Look on line and there are carbon scrubber calculations that will help you properly size a scrubber based on your fan(s) and your room size.

As to fan, IMHO, big is never enough lol!

Make sure you get an in line fan, make sure its a brushed motor fan (can-fan/vortex) that way you can drop a fan rheostat on it and control the rpms to fine tune your enviro. The 6" are usually at 425 cfms, but you have a big ass room you might wanna start looking at 8" or bigger for your room. A 6" @ 425 cfms will do a nice job of cooling your lights if you have them linked together.

Also make sure in your design the fans are "pulling", not pushing.

Hope that helps
