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.
