Yup, I tried that too a few times, but the rates were really low, I think it is in part due to these seeds being very old.

For the hard to germinate seeds what I had some success in is taking some sand paper and gently sanding the outer shell a little bit. It's hard to get right, but seeds will germinate extremely quick afterwards.

Maingrower, in your experience, how long does it take for the seeds to germinate.
