soak the seeds in water for an hour, put them in a wet paper towel, seal the wet paper towel in an air tight container, wait 1-5 days. slight warmth on the bottom is also a good thing. not hot.
some seeds have a very thick shell and might take longer.
how long have you been germinating them?
and has it remained wet/moist the entire time?
please wait for more peoples responses to this as these beans sound magically expensive and i dont wanna waste your time or money
