Ventelation (CFM)

How much CFM will i want in a inline fan to pump the smell out from say like 6x6x8 room? Would 80 do or am i gonna want like 150-200? Appriciate the help.

Is that in foot or meters? Either way atleast 200cfm.

i would agree, two hundred at least. will you be using hid's?

ya i will have like 3 or 4 plants with 400 watt hps im goin to buy in the next week or so and a few clf's to help spread the light.

I already have mylar up now but room not big enough. Movin it to that room when i get the inline fan.

So 200cfm good? Thanks guys gotta go shoppin

Wait! you must factor for size noise and volume. alot if these inline cheap fan simply are over rated. make sure you a fan that can force air under a load.

i agree. inexpensive fans are usually for pushing air only. you want something that will suck air through a filter (the load). if you're going to get a cheapy, plan on upgrading as soon as you can.
