Besides, come to find out that the grow schedule is for a 1000 watt system. I have a Cobb 600 watt and two 180 watt ufo's. The roots are not really massing up, still trying to feed the microbes. I think that it grows better with a higher water level but the root mass must be inside the hydro ton. LED's are like lasers, they beam straight and the Cobb LED seems to spread the light more evenly.
