Greetings, sorry to hear about the Hermie. Pretty sure at this point it's a genetic trait of any plant that is grown from those seeds, can be done but ya gotta clip the sacks. I put 6 seeds in the dome the other day and I know they Hermie, now this got me thinking about why did I. Those sacks pop out 5-6 th node level. Miss a couple, few seeds, miss a bunch plant is insta-reggie.
Think production costs. Honestly you really don't want to perpetuate a Hermie trait? But more power to ya if you want to try. I may Chuck those beans I planted now.
