Yes I did read your quote and you asked how do we explain him not finding seeds,seeing white hairs AND finding the little green ball.And to tell you the truth none of the three means it's a hermie.If those little green balls are seeds then that would mean that one of the plants in his room has hermed out but not necessarily this one.
IMO this plant is not a hermaphrodite,he has taken photos of where the male flowers emerge and I couldn't find one in the pics.
Anyhow I'm not here to argue with you,just trying to help.
