Advice on my setup for ventilation.

[GRoot]

I have a 20 cubic foot suncast utility shed that I will be converting into a grow cab. I will be using 5 68watt cfls for lighting. My question is will a 171 hurricane inline fan attached to a phresh 200 cfm filter be enough to completely stop all smell from coming out of the closet I will be putting the suncast shed in? I plan on 2 Cinderella99's and 2 orange buds going in their. I will have guests over at my house and would like complete lack of smell. Any advice?
Thanks

I would hazard an educated guess that you should be ok with it, as long as your cab is air tight with a fresh air intake and exhaust you should eradicate pretty much all the smell. remember you have to open the door from time to time tho
