In other words, just how much do the phenotypes vary in feminized seeds?
Depends if the breeder has stabilized the strain. Inexperienced or lazy breeder...4 likely pheno's. (altho you might be hard-pressed to see a visual difference at first, growing them out shows all the differences) Experienced breeder with back-crossing (stabilizing the strains desirable characteristics thru selective back-crossing) usually just one, but a maximim of 2 phenotypes. This is my own experience, doing my own femming. (I've never purchased pre-femmed seeds)
