ya, I topped all mine and then I lolly poped them. So each plant has 4 main cola's and everything below that is cut off. So the plant is shaped like a lollypop. It worked well. But I'm threw topping. It seems like they take longer and the yield isn't that different from a single cola plant. We'll see when I harvest. I just don't want to veg for that long anymore. It doesn't seem worth it. Plus I topped all but 2 and those 2 are looking the best.
So it's all experience and personal preferance.
