How far does scent Travel?

Looking to set up a 400w grow room in a urban* area with houses around 10 yards apart what am i lookin at ventalation wise
Any and all help is appreciated
-CooP-

My farts travel up to 15 feet with the right wind patterns

haha use should use a carbon filter for sure. Build you own, its worth spending a bit of money now before you have the po-po at the door

Carbon filters help with that in any grow room... And maybe alex needs one hooked up to his ass.LOL Happy Growing & Peace man

10 yards apart? are you sure you don't live in an urban area?

depending on the part of the house and vents and strain...

itll be in a closet with 2 windows in room both around 15 feet away from closet

AWESOME $15 plug-in activated carbon air filter! It's not ventilation but it helps on the smell. I found mine at sprawl-mart:
