Smell is low I can smell more of the nutz from the room until you touch it and it smells like lime and orange citrus smell. The extract I've read will give your medicine the flavor of the extract. Not sure if it will work since this is my first grow but I figured it was worth a shot . I got my auto BM from Nirvana not trying to advertise but if your looking you see this plant and the only real issue I've had was a pH problem but that's just my city water and was easy to fix with bottle water . I'm hoping for a good yield
