Awesome preservation project! I've been kicking myself in the ass for not buying a pack of those USC Black Affie seeds back in the day. I remember those from way back in the Open Grow/Sannies Shop days. Cristalin has a lot of cool landrace stuff. I haven't followed what he's been up to lately though.
@Rozgreenburn If you end up having some of those to spare, I'd be happy to trade you some beans in return. I've done a lot of breedings and seed increases over the last 6 or 7 years, and would be happy to trade. If you're over at IG, my name is Ohwolfie84.
Have a Merry Christmas!
