venting

[demk323]

I am going to start to grow in a 18fx10f area and I was wondering what kind of fans I need I have one Inline fan 740cfm. Inline fans are better to be used to blow air out correct? Also is there anything I can do so I wont need to put a carbon filter from outside for the smell? Thanks guys
