Odor Control Filter

alright...this isnt urgent but as im not in flowering...but i have a closet grow with the nearest window approximately 6-7 feet away from the door...if i want to filter the smell out, how the hell do i go about doing this? i mean if i shut the door then i have no place at all that i could bring a tube out of there...is there anything that i could put in the doorway that would filter all the smell coming out? i know i sound like a retard but i am completely lost on hwo to do it if you dont have an active vent in the room, all i have is a fan running in there now...HELP

almost everything you need to know is in the Grow FAQ. Link is at the top of every page..... Do what I did read, read, and read some more.... Hope this helps/works. I posted the cheep way, assuming since you don't have any vent you wont want to buy a carbon filter.
