why would somone who has acres of comercial pot growing in columbia or mexico or africa or wherever use anything but the best seeds? if you are on that scale you must know what your doing and want the most yield and highest potency so you get a better price for your crop, just like any normal farmer would when dealing with corn or wheat...
I don't know anything about how the swaag market works really, ive always wanted to know, but ive got some theoreys based on some things i have read. i figure, so much of the stuff is leafy and stemmy because the workers have huge mountains of buds in the fall to clean and basicly just stand by the piles stripping the buds and leaves off with there bare hands into baskets and such and possibly bricked while still wet, causeing the weed to ferment a bit and turn that "brown frown" color and smell funny. a lot of the but was trimmed well and very good buds before being bricked and spending 8 months slowly moving accross the us in smaller and smaller bags till it reached you and its dried up and stale smelling.
the seeds i figure, when your growing that much pot, and your neighbors are too, a few hermies and missed males are bound to apear every once in a while, and the pollen will be everywhere. I heard jamaka was like that, so much pollen you couldn't grow weed anywhere without a few seeds in your bud.
