Sorry to say this guys!
Your both WRONG! In a way,,,,
No matter how a plant is forced to fem. There is NO guarantee of it doing 100% female seeds. Males do happen, and sometimes that male is the holy grail seed for breeders.
I've seen it happen! Just like ISK has, and recounted it here! It is DAMN rare, but does happen!
Science may say one thing but, Nature is a fickle bitch, and seems to have a sense of humor = Shit happens!
This from a breeder's explanation of feminized seeds.
"When I am making reversed lines, there is only one reason I do it. It is NOT to
make it easier for a person to produce an entirely female crop(I'll explain more
later on why this isn't a concern) - I do it to produce a pure line (IE:
Selfing) or if I want to cross a specific line to another and there are no
available males from one of the lines (IE - crossing 2 different clone-onlies).
Essentially I do it to keep lines as true to the clones and selections I've
made.
Why do I not think it's a concern in this situation to try to make an all female
line? Because it can't be guaranteed to always be female and not produce males.
Sexual expression is 50% determined by environment. I don't know how everyone's
grow room is that buys my gear...I don't know how they feed, I don't know what
temp it is, I don't know what medium, etc... There is no way to guarantee the
sexual expression of a plant when 50% of the determining variables are out of
our control. And it's not just us, it's any seed company that can't factor in
all of those variables. It really is as simple as that. there are certain
things you can do to increase the likelihood through chemicals after a flower is
blooming (in the case of cannabis, use ethephon or dutch master reverse -
ethylene is the opposite of gibberelins - kinda like how estrogen is the
opposite of testosterone)."
That help to get your head wrapped around the point?
