yea, just look at it like this, when you top your plant however many fan leaves you have below that cut, let's just say six fan leaves, has the potential to grow a side branch. and with the top cut off, those side branches have the ability to grow up towards the light creating six individual colas. so it just depends on how many nodes, or colas you want. but remember this, the more colas you have the smaller they will be.
now the reason hardroc tops at the third node, and correct me if im wrong hardroc, is because the plant will be able to put all its energy into those six colas, which equals bigger colas. instead of having to share that energy between eight, ten, or twelve colas that will be significantly smaller, and probably less weight than those six colas. me personally, i do four to six at the "MOST".
P.S. i gonna hold true to hardroc's wishes, "BUBBA KUSH ONLY" in this thread, but if you've had that super lemon haze, send me a private msg. and let me know how it is . thanks.
PEACE!!!
