Semillas espontáneas?

If you have seeds its usually pollinated so them seeds will also turn hermie on your if you use them best throwing them away and starting over if you have seeds in one plant check your others if in same place cos chances are they are all full of seeds its bad thing to happen mine never shown any male parts but lost all 28 of my plants. I had to clean everything filter fans lights tent with bleach and start over with new seeds again good luck sorry its happened

No, it is not possible for a NON pollinated female to produce viable seeds. In humans it would be known as "immaculate conception", however, as we all know, a woman can not produce babies all by herself. Cannabis is a "diploid" plant, meaning it needs male and female genetic material to produce viable seeds. If you find seeds on your plant, she must have come into contact with male pollen, there is absolutely no other way for a female plant to develop viable seeds. Hope this helps, Organoman.

If I germinate this new seed and it turns out to be female, would it be "a clone" of the mother?

yes it's possible, the plant "decides that it needs to reproduce" and "evolves hermaphrodite" , so there's many different ways it does this but it can "seed itself" , and those seeds can be viable. But like you said it will retain the same genetic as the "mother", but "the mother is also the father", so "the child has a high chance of being a hermaphrodite also" , and usually you do want to avoid this gene in your lineage. Hope this helps ! 🚀

If you use feminized seeds, it's not uncommon for some plants that haven't been pollinated to produce all these mini seeds in the buds. They can spoil the taste a bit and are a hassle to sort out. You can read more about it online. Also, it can happen that a female plant hermaphrodites and becomes male (e.g., if it gets too stressed) and then pollinates the female flowers of the other plants in the room.
