Hi, I've been looking at the Grizzly website to see if I can work out what this is... I believe it may be a "CG", rather than a "CF". If that's the case, it could be Connoisseur Genetics? I still can't quite work out the "KYU", but I suspect that perhaps it isn't "KYU" after all... my best guess is some sort of auto-Kush from Connoisseur Genetics. I hope that helps!
