and possibly horrible genetics, and poor potency, you don't know and that's why people pay for Known good seeds from a reputable breeder, so you do know the genetics.
It's this simple, for people like myself, who spend up to a $500+ to set up a grow room, i'm not going to waste my time and money rasing a questionable plant, I am going to grow known genetics, a good strain, also I can choose a strain that fits my situation and the high I like.I look through strain guides and study the history of the strains I'm interested in, I read what other people have to say about the strain(like Jason King author of the Cannabible), when people buy good seeds they are not paying $ for the seeds, they are buying everything that goes with it, like the security of knowing you have a good chance of growing some killer weed as long as you do things right while rasing those beans.......
Plain and simple...
