I agree. The mexi brick is most likely old landrace sativa with high yield traits. Stabilized through season after season of open pollenation in huge fields of cartel ran grows, using same seed stock for many years. As natural as it gets. Shit. Some mexi comercial is pretty good as far as potency, yield, desiease resistance and so forth. It all tastes swaggy due to improper harvesting,drying,andcuring tecniques. Who knows. Breed it with some known killer genetics, and you may produce a mean hybrid! Good luck.
