OK- so about 5 years ago I germed an original pack of Bros Grim 99's. I had them on ice for about seven years. I was really surprised to get 8 of them to grow. I think I ended up with 2 males and 4 females after losing 2 young ones along the way to mutancy. Well I made thousands of F2's because even back then that filial gen was very rare. Well today, I can't get a damn one of them to germ. My deep freezer kicked out when I was on vacation a few years ago. I've even tried gib acid on a 20-30 cross section. They're still on ice, but it just kills me that I can't get these to pop.
