I've got 4 288.2 Quantum Boards plus a 6-inch iPower fan to power which is for 2 4x2 tents. I'm growing the colas like lollypops in the 7 gallons (instead of topping to turn that single one into 4 or more) to cram them all in one tent. The other is a scrog that are cuttings from the lollypopping that just got a screen (tallest was 2 foot tall so it was time to smash it all down and start tucking) and will be flipped in 6 or more weeks (I want cuttings from it for when the colas are done and that tent needs plants).
Following is what the OP posted: " . . . . ‘rest’ after producing energy for 18 hours a day. Darkness is as important to the growth of most plants as light is! Your plant would get exhausted and burn out if you keep it under light all the time! "Im pretty grateful to be able to hear gunshots from all directions at night time, it’s actually very comforting while sitting out on the porch knowing what a deterrent it is to intruders. No crimes to report in our area really. Nor protests
on the original topic though. I don’t particularly believe more light will make a plant have more growth. And when referring to more light the question still hasn’t been defined of brighter light or longer on periods... When in reference to intensity, there is a point when you can actually give plants too much light and stress them out, in some instances even “bleaching” the plants white. Before playing with light intensity you should have all other variables optimized in your room first to reap the most benefits from it. Simply adding more light won’t determine more growth either, although it is a general rule that what spectrum of light is used doesn’t impact the plant as much as increasing the number of photons the plant receives, playing with uv-a and uv-b certainly does have an impact on bud quality and density.. When speaking in terms of length of time on, this topic has much debate to be had for many years to come. But in my opinion, different types of plants are going to react differently, in simple laymen’s terms, an auto flower plant is going to benefit greatly from a 24/0 light period compared to a plant that doesn’t have ruderalis genes. I personally have experienced from multiple runs with northern lights, higher yields from plants that were vegged under 20/4 than plants I had vegged under 24/0. However, I have also experienced the opposite with other strains like c99 which has genes from Jack Herer, a very vigorous strain. It certainly is a topic of much debate and research to be had. But one has to remember, there will always be soo many variables to consider that your almost certain to never receive the same results twice.

Thanks for that Elvin,Following is what the OP posted: " . . . . ‘rest’ after producing energy for 18 hours a day. Darkness is as important to the growth of most plants as light is! Your plant would get exhausted and burn out if you keep it under light all the time! "
And that is what I deemed as "weed forum myth"
I will repeat again, cannabis does not need "rest" because it is a C3.
If you do not believe Agronomy textbooks, how about Ed Rosenthal?
Certainly, you do not want to disagree with Ed, do you?

Marijuana plantes photosynthesize as long as they receive light as well as water, air, nutrients and suitable temperature. Photosynthesis is the process in which plants use the energy from light (primarily in the blue and red spectrums) to combine carbon dioxide (CO2) from the air and water (H2O) to make sugar while releasing oxygen to the air.
Plants use sugars continuously to fuel metabolic processes (living) as well as for tissue building. The plant combines nitrogen (N) with the sugar to make amino acids, the building blocks of proteins. They are the substance of plant tissue. When the light is off, the plant's metabolic processes, respiration and growth, continue.
The plant can photosynthesize continuously so it produces the most energy and growth when the light is on, continuously. Continuous light does not stress the plant, which reacts somewhat mechanistically to it.
Plants under an 18-6 light-dark regimen are producing sugar only three quarters of the time. They are thus growing at only 75% of their potential. Leaving the light on continuously will result in bigger plants, faster, which leads to higher yields.

Stretch is very dependent on darkness which is why you want some but weed does not sleep.
GG#4 that I bought, OG Kush and Amnesia that were freebie seeds and some Purple Kush that were replacements (Crop King had a bad batch with really bad cold germ at one time and they replaced a couple of years ago that I needed to pop before they died)
Ok,I guess I mis-read or mis-understood your lollipop method,which I recently read about how to,but absorbing the differences seemed easy.
Actually "lollypopping" is done because with light does not reach that first 2 or 3 feet of the plant so all those branches go. Then you bare the remaining side branches except for the ends.
9 bags at 7 gallons each is a lot of dirt (and my SCROG tent has a single 30+ gallon rectangle bag) even with perlite BTW. I'm glad it is from the ground not a bag because that would be costly.
Not going to be the "world's largest" by any stretch but I'm not wasting time by topping a couple of times.

Believe what you want, I do not care; I really don't.Well I never did specifically say I don’t believe in agronomy or Ed, however I do believe the question has too many variables to be able to adequately answer to be completely honest. I know it’s a big argument that plants photosynthesize as long as they have light, but if that’s the case, why have I had multiple crops that have yielded more weight with a 20/4 schedule than their sisters that came from the same mother, that were under 24/0, then flowered together in the same room after vegging the same exact time?. 10% average more roughly to be exact consistently over a 4 crop cycle. I’ve also had opposite results with another strain.. Genetics certainly play a big role, as with every other aspect of growing, the bottom line usually comes down to genetics from my personal experience. I know I’m no career gardener or scientist but I do have over 10 years of consistent growing under my belt, surely that counts for something other than an expensive hobby
I certainly believe and respect a lot of the research that people have done, and certainly no hard feelings, I can agree to disagree
Actually the question should have had more detail in it,but it was a good refresh for me,and I learned alot about artificial light and how cannabis responds.
