thats nature's way of tryin to make sure the plant's genes carry on..the plant recognizes the feminization attempt taking place and pushes some males forward for self preservation.
...or sumthin like that LoL
pce
Both yes and no. In nature, with pure strains, under certain conditions if females are not pollinated by a certain time if the right conditions occur a percentage of them can and will hermi and pollinate females. But not all females would or could do that, not in totally pure strains when it comes to pure female plants. Other females are not pure females and they will turn and they will pollinate and they will keep the species going.
There is such a thing as a pure female and even if they hermi, which is VERY rare, it is what is called a natural hermi and the pollen will be sterile. If you can take a female or females and switch them from veg to flower for two weeks and then back into veg for two weeks and then back into flower and not get hermis .. then you have a true female with no male genetics in it. Those are female plants that should be used to make feminized beans. If not you are not only passing on some male genetics but you are in some way causing it to surface more or intensify the tendency more.
Even going back just ten years ago you seldom found threads about plants turning hermi, but now hardly a day goes by without a tread or two, ore more, about someone's plants turning hermi showing up.
Ever wonder why that is?
Those are rather difficult to find these days because long before that was known crosses were made that had some male genetics in them and those old crosses turned out to be the basic building blocks that the modern strains of today relied on and have some percentage of them in them.
When I first began to grow you almost couldn't make a plant turn hermi but now with some strains you can do your very best to avoid it and it can still happen.
