That's what quadlining is; one topping above the 4th node and the LST'ing the kept branches. You control the width with the LST part.Question on quadlining....does it make the width footprint of the plants any wider than just topping and some LST? I'd like to quadline one in my new grow, but typically 4 plants with topping after 5th node and LST fill up my 4x4.
My quads flower 2 at a time, side by side, in a 1m x 0.5m (36" x 18") space so each one gets approximately 1.5 square feet.
