I think giving them more light towards the end would confuse the plants and make them grow longer. In nature, the days get shorter and shorter as they get closer to maturing, so I would think that adding more daylight would just take them longer to finish. You might get some more growth but you could also add more stress and add time to the growing process. I have heard giving them the 48 hours of dark before harvest increases resin production, but I'm still a newb so I have no clue as to whether or not it really works. Good luck! :thumbsup:
