like as in feminizes seeds?? if so then this means that the seed you plant is supose to be a female.. you dont have to go through the hassel of sexing.that they "should" all be fems.. usually you will either get fems or hermis..
my first experience with feminized seeds haz been great, i still have a cutting of the first seed i planted and harvested twice now.. with no hermies.. which is awsome.. (knock on wood) LH
