Maybe I need to let them so for a little longer. I practically plucked from plant and threw them in a cup of water. some cracked. It’s just the bandaid x (Mac x aaw) that I’m having that problem with so far. I’ll check more beans just to see and will let you know what I come up with. I also have some pollen stored of a few diff kinds. Few diff crosses and a whole shit ton of out door plants. I’m still leaning the ropes when it comes to chucking / breeding so I will keep trying to improve. The seeds seemed mature. What would make them not crack?
