No prob FB.
A MJ plant showing sex at maturity is not the same as a MJ plant in bloom.
You can keep a Mom in the veg state as long as you want, with her showing pistils indicating she's a female, yet she's not in bloom until 12/12 is started.
You can do the same with a male plant, though more risky, which is why some breeders just clone their males over and over too.
A female from a good, stable strain can pretty much veg indefinitely on 18/6.
A male on 18/6 for too long will give up some stray pollen, and especially with less light (17/7 ; 16/8 ; 15/9 ; etc..) and may actually bloom b/c IMO they are more sensitive to ligt changes since they have to be able to pollinate early enough for the female to have enough time to make viable seeds.
MOST male strains show 1st under optimal conditions b/c they have to mature and do their job 1st (make & give viable pollen), so the female can then do her job afterwards (make & give viable seeds).
One such strain that is notorious for males showing sex 1st, IN VEG, is Cinderella 99 !!
hi flo, well that was a nicely detailed answer, thanks, that explained a lot more to me, ok so mommy was right... ask & yee shall learn....lol
