no not a joke at all, afghan landrace and paki landraces are real, green crack is a clone only indica from old (like 90's?) sensi seeds skunk 1 stock like cheese and genius (genius is a parent in the cross of apollo11) most people take it earlier because it finishes fast and has a zippy sativa like high, so my question was just lining up letters in afpack , af=afghan ,p= paki, ack= green crack
