I've actually never have grown Querkle (although I just got HS's cut this weekend) so I can't really tell by the plant structure. However, from the turpine profile I would say that CK4 is definitely Querkle smelling. CK4 is my favorite so far as she has SUPER thick stems and awesome structure. CK2 just has a fruity smell that I can't really pinpoint yet. I can't wait!
I also just finished sexing the 303 Ski Patrol and I got 2 girls and 2 boys.
