    Fans - Not just blowing hot air!

    bronc how big of a space is that in? I have a 4x11x8 closet and was wondering what size fan to use for odor control and temp control. Im not sure at all what type of fan to get.

    Fans - Not just blowing hot air!

    I have a fully insulated,independant grow room that is 4X8X8-could someone give me an idea of the size of fans I need for intake and exhaust.I am using T5- 4 foot doubles one per side and one overhaed-and my temps are up around 90 to 100.My present fans are just two-4" and arent really working.Any input would be really helpfull-the plus side my plants are in crazy bloom-3rd week.

    1. fans require cooler fresh air to draw from and a place for the hot stale air to exhaust to.

    cfm listed above, one exhaust fan is usually enough in a sealed system
