I was thinking more of lollipopping plants that vegged 5-7 weeks. In that case it seems the plant is being reduced to match the lighting, and therefore a waste of time growing it larger than the lights. That it would be better to veg less so the plant is sized to the lights, or add lights to make the most of the investment in growth.That being said in a SOG your plants are very young when you put them into flower
I don't know anything about SOG. Maybe it's justified.
