What is the dj birdseed method? I have some Indian seed now and not that many of each strain.
He uses it "by applying pressure along the seam of the seed(...)", to be "assesssed for quality and maturity."

So if you or others fancy, what you might try is as easy as after a holding a single seed between your thumb and pointing finger, apply little but crescent pressure along the seam of any desired seed until you feel it pop. This seems easier to do after a soak, or some days on the towel, but anyways after the shell pop's it wants to start their journey, or so it seems in my case.
