First of all, a big thank you to Dell, Steve and all the donors who make the seed exchange happen. Kathleen's comments about winnowing seed brought back a funny memory for me. I've been winnowing seed for decades, and I usually step out onto the front porch to do it. My method is as simple as it gets: I spread a portion of the chaffy seed on a sheet of typing paper, cup and pinch one end of the paper, and then blow across the sheet from narrow end to broad, open end.Once, a neighbor passing by saw me doing this, stopped and stared awhile and finally asked me "is that marijuana?" It wasn't, and at the time I didn't really understand why he might think it was.Some time later, I got the probable connection: back in the day, viable marijuana seeds were sometimes a component of parrot feed. If you wanted to grow marijuana, you bought parrot seed and then winnowed it to separate the marijuana seeds. There's more to this story, but this is enough for now.
