I just back crossed the Green Crack. It's the same one they call Cecil's Cush or just Cush with a "C", the one that was also grown by bunz that snoop dog supposedly named Green Crack.
I started by crossing her with a male c99 quite a few years ago. We made f2'a nd now F3's with the C99xGC and we call it Apricot Cush. AC has an awesome tangy flavor with a nice long lived effect that ya don't ever get totally used to. It's quite popular locally and we never released a single clone but do have a couple friends growing it in Flint and Burton. Anyway we used a prime AC male onto the green crack clone to make the back cross. I'm quite sure it's going to be very nice. The seeds are still on the plant but will be harvested soon. Can't wait to try them out.
