When you crop the tops instead of topping, the plant sends out growth hormones which benefit the entire plant, not just the bent over/damaged part it is attempting to repair. This causes the lowers to catch up to the main top, giving you a bush rather than the classic xmas tree shape. More tops, more weight. I generally crop the main top first, then later as a few lowers start to catch up, I pick a horizontal line across plant near top and crop all the tops above said line, giving more lowers a chance to catch up. Like mainlining or Uncle Ben's (I think that's what you call it) you're trying to redirect the majority of the hormones or auxins away from single cola dominance and redistribute it throughout all the tops. I utilize it throughout veg.
