I'm a little compulsive, but here's how I harvest seed:
I remove the seeds from the pods, making sure there aren't any little pieces of placenta stuck to them and tossing them into a fine mesh strainer. I rinse them thoroughly, then tap the strainer out onto a large paper plate labelled with a sharpie. They then go on my dining room table (can't tell you how much the missus loves this part of the arrangement) under a ceiling fan at warp speed. I turn them a few times while they dry; I usually let them dry for at least three days, but usually more like a week. The temperature is somewhere between 70 and 72 degrees. It's also important to store them at a temperature that's pretty cool; heat and humidity are the enemy here.
Did I mention that she also loves the various mashes all over the place?
