depending how far along it is, several plants wont start to stink until the 3rd or 4th week of flower.. some skunk strains stink 2 weeks from seed.. it just all depends on the plant.. being outdoors with good ventilation, i would think the smell would be minimal just because its getting aired out 24/7. some sativas i have seen don't stink ever rather have a bit of a fruity smell.. again i think it all depends on the strain.. skunk being the smelliest..
