"Lollipopping" allows the plant to focus growing at the canopy, not necessarily the main colas. Main colas really only come off the top of the main stem. Primary and secondary colas would be a more accurate term. But the clarification was for the fact that the action takes place at the canopy. With some adequate side lighting, "lollipopping" would be a waste of time. It has been said adding side lighting (or any even lighting) is the best way to increase yields, rather than waste the energy and time the plant has spent growing. I personally top all of my plants and use LST a lot. Pipe Cleaners are my shit.
