As soon as I have more of some seed type than I want, I assume it is a glut in everyone's stash. And RisingCreek gave me a lifetime supply of radish seed after hitting some eBay site or year-end sale.
Once I get a few more NEW seeds split and labelled and made visible, I'll go dig out some radish seeds. If I was willing to just say "assorted small roundish radishes" I could probably list many pkts. But counting each type, recording on paper, then entering each name separately - the part Dave coded is easy to use, but digging and counting pkts takes time.
I used to have huge amounts of saved Daikon radish seed when one crop went to seed. But I think I gave most of that away.
