Are these seeds any good?

The white on the sides are on the shells and they are from different mothers, same father. They are 4 weeks from fertilization and the plants are 6 weeks into flower.

no your seed is split exposing the young calyx you can always try them to see as some seeds can go through a lot. i would just look for better seed that normal

Try em and see...

Did these come out of some flower? How mature was the flower? Unfortunately, to me these do not look like they are mature. I could be wrong, however. I guess there's only one way to tell. Try and germinate them.
