Was in a rush, what I was getting at is that most all plants that require pollination / Male/female plants , have a way of self pollinating themselves in a last effort to survive / reproduce itself. Being if you induce by stress or it naturally comes by season or lack of harvesting. I after research , now think bananas , nanners , are not a true Hermie but maybe just a sensitive plant, to spikes of all , if lightsleaks , ph , and temps or any inconstancy. And are just doing what it can and does.
And the whole identify the seed by the shape , all the seeds ive pulled recently investigating have the most perfect volcano shape pit.
Stress. well said.
