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,the bud is really pretty good most of the time, i mean tons of people do grows with bagseed, it doesn't grow as a brick off the plant, it looks just like all pot plants, and if dried well and stored well could probably be decent bud if it didn't have many seeds. the problem is the third world farmers who grow it in bulk have so much of it to clean so fast they basicly have hundreds of workers around a big mountains of buds in the fall to clean it and get it ready for drying and bricking, and basicly they just stand by the piles shucking the buds and leaves off with there bare hands into baskets and such so the bud ends up leafy and stemmy some times.
Then the bud is 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 bud was trimmed well and very good buds before being bricked and spending 8 months in warehouses slowly moving accross the us in smaller and smaller bags till it reached you and dried up and stale smelling.
my theory on the seeds is, 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. there is bound to be lots of wild pot as well there and that could interfere as well...
