I am a believer that there are good genetics to be found all over. I agree with napa that most of the time it's schwag because the people just threw down seeds and didn't bother to pick out males or manicure and cure it properly, not because it's bad weed. You never know what kind of genetics you could get out of a seedy bag but chances are if you took some seeds and did some breeding you could work out the genetic traits you like and create a very decent strain from the genetics you were given. That's a lot of work though when you could just find some already good genetics for close to same price as that ounce of schwag (it's twenty bucks out here last I heard)
