there are ways to influence the outcome a little. generally works for me, getting @ 80% females if conditions are right and not messed with during the first 5 weeks.
I have 7 in week 3-4 veg right now (2 more weeks before I clone em for sex) and some new beans I picked up from Centennial Seeds ('21' and Roughneck) will get started tonight (full moon, winter solstice .... should be some great beans poppin!!!)
oh yeah man just dissolve some birth control in the water that you germ your seeds with haha (this is total sarcasm in case it didnt come across in the text lol)
