The pod started to crack open a tiny bit after 70 days, so I sowed it. The seed is good. I can see embryos with a hand lens. The pod was not completely ripe. Some of the seed was dark and loose, while some was green and still attached to the pod. Some interesting observations:
The seed develops from the base of the pod to the top. All the loose seed was in the bottom portion of the pod.
The seed chambers develop at different rates. The first seed chamber was about 1/3 loose seed and 2/3 green seed. the other two chambers were 2/3 loose seed to 1/3 green.
Thanks to Eliseo for posting information on which medium to use.
