I think the guy in Midnight Express was smuggling something stronger than weed,  but laws in other countries kind of freak me out. You probably hear really bad things about getting caught with weed in the US but it is getting better. 

I have not grown either of those strains from Nirvana but they do have very good Kush strains and I do love a Kush, never had a bad one. 

How many plants are you thinking about growing in your tent? I have never heard a single grower complain that their tent was too big.
