It could be that you were just unlucky on that plant. I honestly think that no matter the parents finding a hermi plant at some point would probably happen with any line and the fact that shantibaba is supplying probably in the ten of thousands of seeds that even if hermaphrodite only shows up 1 in 200 than and he's giving 18 or more seeds per pack than really 1 in 10 or 11 people will get a hermaphrodite plant. It just sucks if it was you and it does suck to have your plants accidentally pollinated. But you also have a one in 5 chance of finding a 1 in 100 keeper that would probably rival everything and be the new standard for other plants. It's numbers nature and luck you play with all three and I'm sure you'll find a winner. Good luck.
