Hermi more then likely.  Why did the plant produce seeds? Was it genetic or environmental? If it's genetic it's probably a hermerfadite if its environmental they will probably be female. All the breeders do is treat what ever part of a female plant they want to make 🍌 's and pollen with collidol silver or some other environmental change. I changed from hps to all led about 2/3 through a flowering cycle and it made all 3 of those plants make a small amount of seeds. First it made 🍌 's then after it was dried I found some seeds.
