I was looking at the photo-period graph in Marijuana Botany, and according to the graph, maximum THC production occurs with about 10 hours of day light. Doesn't that seem logical that when you are flowering, you should reduce the light period to 10 hours during the last 3-4 weeks for maximum effect?
