True, a photo can be vegged even under a 24/0 light cycle. I believe most do 18/6 because it's cost-efficient (as you said, excess light is wasted).Not quite as cavalier as you might think, although I am tenacious.
It is my understanding that the cannabis plants do not require a dark period in veg. That plants can only take in and/or utilize so much light, what is in excess is wasted. What I am attempting to do is dial it in. I’m fairly confident I can get there utilizing the hours of light, % of power and distance to canopy. Enjoy the day.
I did not intend to question or place doubt on your method. I'm just here to watch and observe the magic!
I am just as confident as you are that you can pull this off. I'll be here.
