a hermy carries an extra chromosome, XXY.
you can't force a "pure" female to produce pollen unless you use a chemical agent. it is the only way to get true feminized seeds. any other method and you are working with a genetic defect.
what about light stress?? won't that produce hermified traits in a non hermi plant?
I really dont understand the point of scrog outdoors, i thought the purpose was to keep an even canopy because artifical light can only penetrate so deep.. but the sun can penetrate all the way to the grouund right? or no?
FDD, i hate to contradict you but you can make any plant hermie. or at least make it produce pollen sacks. by leaving it several weeks past its harvest date, for self preservation purposes, the plant will grow pollen sacks to self pollinate, if pollination has not already occurred. is you harvest this pollen, and pollinate another different female, this will make feminized seeds. other than using chemicals, i think it is one of the only natural ways to produce pollen from a female plant. like 14-16 weeks into flower it will produce pollen sacks.
also you are forgetting a very key thing in genetics. mutations. they happen all the time, this is why you can get a hermie from something that only has an XX or XY. a mutation can occur and form that XXY chromosome to make it hermie. this can happen to any chromosome or base pairs when sequencing TRNA for polypeptide chains, by switching a once paired A-T=G-C=G-C, to T-A=G-C=C-G. in animal or plant cells. mutations also cause cancer in cells.
Sounds like your searching for the holy grail and the fountain of youth at the same time.
Actually I wont touch feminized seeds, and I would never use them to breed with. But since your doing so well I wouldn't mind growing out some of your seeds I bet I could make them pure girls grow dicks.
but it isn't just people nature does it too pollen can carry on the wind as far as 200 yards or more. Do you think that all cannabis was dioecious before we started treating it with chemicals? Or was it a natural adaptation meant for survival of the specie?
