how important to you is this plant? do you have others going as well or are all your eggs in that one basket? If it is important (even if not, it never hurts to have the stuff all ready to go right away when you need it in case of emergencies.) to you their is a product that will kill male flowers and stop them from forming more-it cant undo a plant being pollinated sadly though. its called dutchmasters reverse and you need to use it with a product called dutchmasters saturater or penetrator(they are the same thing, for some reason they recently changed the name to saturater from penetrator).
Lol I still have a bottle of "Saturator"..But anyway, darkdestruction had the best answer for you. If you want to save seed stock count on the Hermie trait to be passed along to much of the offspring..The plant is healthy and happy from what I can tell, and unless it's undergone severe stress of some kind before the onset of flowering you can count on it being genetic hermaphroditism.
It's not that important, just messin' around with some bagseed. I wanna maybe start breeding. Just wondering if this hermie's mother is worth keeping. It's a good phenotype, grows fast, shows early. Anyway, like I said, just wondering if it's worth keeping...?
