Q: My exhaust fans never turn off?  Is there something wrong with my controller?

A: Absolutely not!  This problem plagues a lot of growers.  The number one issue is fan size.  Most situations require you to increase your exhaust fan size to accommodate your room size.  You should be able to 'turn' your air in 5 - 10 minutes.  This keeps cool fresh air on your plants and allows them to 'breath' properly.
