OK. I have an interesting theory. So Mexicans have been growing marijuana for decades... They are probably responsible for most of the marijuana that has circulated through the United States over the past 60 years. Not to mention they MASS PRODUCE that shit. So after all this growing and growing... You'd think that they must have learned some shit. So basically what I'm saying is that they must be growing the plants they grow for a reason. Time is the most important factor for them, they need it fast. So they probably use pretty fast growing strains. Not to mention they are outside, so they would need a plant that has good resistance to disease and other environmental factors. I've also heard Mexican weed is hybrid, so they can keep the plants smaller and get larger yields, and some other stuff. I think that Mexican weed like "Mexican Dirt Weed," "Red Hair," and others are the strongest and fastest growing plants. I also have a little bit of proof from a friend: My friend had Northern Lights seeds Mexican Dirt weed seeds. He started growing them at the same time, but the Mexican Dirt weed was like twice as large and healthy looking than the Northern Lights, which were seeds from a Seedbank in Amsterdam. What do you think?
