Some one correct me if I'm wrong, but I think that the CBD in the MJ is the chemical that smells. Therefore the more CBD, the stinker the plant. I am trying out a G-13 x SS, Just pop up. About another 4 months. Can't smell it yet, but think it will later. I do know that the more CBD mix with Thc, gives you more of a couch lock, or knock out. Good luck all, and happying growing.
