My research has taught me thus far, that Female and Feminized are not the same thing.
A feminized seed is one that’s been created by forcing a female to produce male flower parts. Usually with something like colloidal silver, or silver thiosulfate. When this feminized pollen pollinates with a female plant, the lack of any male chromosomes produces female plants.
This is basically the same path an environmentally (similar to chemically) stressed hermie takes, so all seeds will be female. There are no male chromosomes in the process. Now we all know that “nature finds a way”, so it’s only 99%, and an occasional male will still be produced. The uncontrolled (unknown?) nature of an environmental stressor can also have more uncontrolled results I’d imagine.
If the plant hermies from genetics however (a “true” hermie) then there can be males and females, and yes, more hermies.
