Each method is different and not necessarily related or correlated to the other. It just depends on what you're trying to do. You may want to take the time to research each method, see why it's done and then decide what to do. Good luck.
I'm gonna supercrop because my canopy is only 7 feet tall and the lights take away another foot and a half so I need to shorten the height of the plants. So should I top before I supercrop or supercrop first, let the branches grow back upwards, and then top them?
