This schedule would seem useful but only if the amount of CO2 (if any) and ferts (if any) are considered along with the light. So, for example, if you have "high light" as classified in that list, but no CO2 supplementation and no fert supplementation, then keeping the lights on at such intensity for 6 hours would not yield healthy, robust plant growth. That chart is handy, though, and if someone already has a certain level of lighting that would come into the "medium" or "high" catagories, and wants to grow a wide variety of plants, including maybe ones with redder coloring, then consideration should be put to CO2 and fert supplementation. If on the other hand, the lighting is there already, and CO2 supplementation and fert supplementation isn't possible or preferred for any reason, then cutting down on the lighting (photoperiod) and choosing "low light" plants is the best option.
