Exhaust Fans ??

[Absent1]

My grow room stays at about 82-85 degress when the lighs are on, and about 74-78 when the lights are off, let me give you the grow room size.

Grow Room:
4 ft wide
5 ft long
8 ft high

I am wanting to know which exhaust fan would be the best, out of the two I have pictured below.

- The one above moves 180 cfm and the one below moves 160 cfm

Hi,

Your room is 4 ft wide X 5 ft long X 8 ft high = 160 cubic feet of space therefore the 160 cfm should be sufficient enough to change the air in your room every minute....
(as you might know,cfm= cubic feet minute)

If you think you might upsize you room in the future,then go for the 180 cfm that way you'll save extra expenses down the road but if you stick with this size room buy the 160 its more than enough and you save cash now.

Hope this helps.
