we weren't talking about "true hermies" as i have never seen a true hjermie othr than in pics. we were talking about when a female plant puts out a few male flowers late in flowering. some strains seem to do this more than others. i think it is a self preservation instinct or more accurately a genetic preservation instinct. all living creatures have a natural compulsion to reproduce. a female plant senses that the end of it's life cycle is near and it has not been pollinated yet(virgin) so in a last effort to reproduce and pass on its genes to another generation it produces a few male flowers in the hopes of self pollination. some plants/strains seem to have this instinct to a greater extent than others. remember, these hermies can be caused by stress as well. everyone reading this must be aware that these are just my conclusions based on personal experience as well as alot of research over the years. although this theory makes perfect sense to me others may disagree.
