yea basically because you could keep a mother plant or two and have a continuos supply of female clones opposed to purchasing seeds everytime you started a new grow of afs or take the time to weed out your male and female plants from the seeds that your af produces. of course clones grow alot quicker than when you start fom seeds. not to mention ive seen way bigger yields from regular plants used in the sog method than a large cluster of afs but thats just from my own personal experience
