I only use reg seeds and one thing I found over the years was that starting seeds with a long-hour photoperiod will yield mostly males. Starting lights with 16 or 18 hr photoperiod is not natural. When I start with a 12/12 and extend weekly like in nature, I have a much higher ratio of females.
On the grow I'm on now, I used this method with 3 strains on 13 plants and got 12 female plants and 1 male.
