Newbie Q? on fans

hey everyone ive never grown before but i am starting to get everything together to do one of these Rubbermaid Box grows. I will have it in an attic where there is a small wire screen opening to outside, that really isnt visible due to the shutter like wood panels shielding it. I was thinking that I could have both Intake and outtake fans going through the wired screen outside (by cutting a hole to fit the exhaust lines or whatever you may call them through the screens) and taking the air from outside in to give the plants air circulation, and having the outtake for removing the smell/ hot air and throwing it outside. They will both be separate lines. Please let me know if this would be fine (if you don't understand what im talking about please post and we can clear it up of what i want to do) Thanks and any advice/ help is greatly appriciated :thumbsup:

Sounds... good. :)

Give it a go... you will find that the more you actually "do", the more you come up with solutions.
So... yeah! Give it a go! :)
