homegrown man, screw getting weed from Colombia, whats he thinking?
just find a homie you know that grows, so you can get it right from the grower, or a dealer that gets it straight from the grower.. you can usually tell if they do by the quality of there weed and how honest they are with you..
i get my weed from a few different growers... all very very potent good buds.

why dont you just get some mexican weed, and get some homegrown and just smoke them in person, you will find out whats better
