beautiful picture.! i really like how you pop open tge shell.
It was just a test to see if it would work. The shell is only there for physical protection. It's pretty easy though, I said scalp but it's more like scraping. If you scrape the edges off you can pop it open fairly easy.No shit? Never heard of doing that before.
You must have a steady hand.
But I was being sarcastic, seeds pop "despite" many of the methods used, not thanks to. When seeds really don't pop (even when the conditions are optimal), remain dormant, for example old ones, it's either the shell or the embryo. To exclude the former, you can damage the shell physically just a little (like putting it in matchbox with sandpaper and shake, or scrape off a little of the shell).
Good read on seed dormancy: http://5e.plantphys.net/article.php?id=8
Seeds pop when they reach a certain threshold of water contents, which obviously is done a little faster when soaking the seeds. Which I do because I got plenty of seeds and allows me to pick those that pop at the same rate (a few days difference is a lot especially on hydro...), otherwise I'd just put them directly in the medium.
