Hmmm, I have seen that seed chart somewhere else awhile back. I once sprouted 15 seeds and all 15 turned out to be males...wished I had seen this before I wasted all that time n money. I am mostly cloning lately (because of that fiasco), but next time I crack some beans, I am going to examine this very carefully and see how accurate this method is. I'm sure I won't be the only one either! 100% accurate? Let's just say I'm skeptical, but anything close to 100% accuracy would be very nice indeed! It would be very nice to be able to identify a female seed every time. Thanks for posting that Rainhaze!
