your plant produced seeds for ONLY one reason, it was 'pollinated' ... either another plant had male flowers, or your '100% female' produced some male flowers (hermaphrodite) ... that's the only way it happens ... I've never had a hermaphrodite, but seen plenty of them ... you can still smoke it, of course, but otherwise, I wouldn't use it for producing seeds, or breeding ... 'hermie' sex changes like that demonstrate weak genetics, (in MY opinion) ... you can use the "but, it may produce more females" argument, but (in MY opinion), you're just propagating more weak-genetic plants, something I would avoid ... again, that's just the way I see it ... good luck :thumbsup:
