the smell

So I'm planning on growing maybe something around 6-8 plants in my closet. I was just wondering how bad the smell gets.
Just trying to get a feel on this issue for whether i decide to build a filtered/ventilated grow box in my closet, or just build a garden without such containment.

The closet is like a separate room, attached to my room.

it's gonna stink... your growing Marijuana.. what do u think ??

i grew a lowryder one of the 3 i planted came out female.. and that one plant stunk my room .. and u going to be having 6-8 pants... u best get a carbon filter

gotcha, thanks for the input
