It was a female, it is a female, but he said himself he interupted the 12 hour dark period, thus he stressed out the female plant, he confused it, he broke the dark period, so it turned hermi, it would have had small sacks at the bottom where his arrow is pointing, he never seen them, they opened and out came the pollen the white dust he is pointing out now that he has seen it.
So yes in life it was going through a female, not all plants do this but this one has turned hermi.
