No smell!? WTF is this!?!?

early misty was the first strain i ever grew indoors , its a nice smoke , full of crystals , but yeah it didnt smell all that much during flowering , but it still turned out ok , i remember mine being slightly more sativa dominent and if i remember correctly it went 11-12 weeks flowering .
now if you really want a stinky strain , try big buddahs blue cheese , damn this strain stinks , ive got a fem on 12/12 from seed , its about 4 weeeks old now and it stinks allready , im gonna have to keep an eye on this one during the next few weeks coz if she gets to bad ill have to get rid , ....to many nosey neighbours around my new location .

I am thinking of buying a grow tent but before I do how does it hold up to the smell of a flowering plant? I will put an activated charcoal filter on the end of it will that be enough to catch the smell of one of the stronger smelling strains when flowering?
