Well, I will try my best to explain more of column B. The column A part, I had a hard time finding any information on this such as yourself.
In my experience:
14/10
12/12
10/14
6/6 x 3
I simply had to try it and see if I liked it. Personally, the 12/12 works best for me. What I noticed running the other schedules is, the 10/14 idea produced the smallest yields. Hands down. Something about the last 2 hours that makes a difference, it's sort of like the flowering cycle.. the last 2 weeks seem to be where some serious mass occurs. So I noticed the decline for sure using the 10/14. Were my conditions different? I wouldn't say they varied too much so I will say yes, I got consistently lower yields.
the 6/6 x 3, I had a rapid slowing of growth coming out of a strong veg cycle. Plants went from 2-3" per day to bearly moving at all. Transition was weaker. Flowering turned out nicely though. They also ate and drank water at rapid rates, so.. my PH and PPM were always bouncing and I was always having to keep mind that it was 6/6, so, for some people, it's a bit inconvenient at times to make corrections.
the 12/12 seems to have the best transition and overall quality though. the 6/6 might have been bigger than the 10/14, but the 12/12 gives me the best size AND quality.

well if you think about it 10/14 your cutting out 2 hours of light every day for 56 days based on a 8 week flowering time, that 112 hours of potential food making for the plant that its not revieving.

I agree. It was sort of like the defoliate or not subject. Some say yay, some nay. I just experimented and found out what worked best for me. Same with the lighting.

..if 4/4 worked better..im sure we would all be 4/4 by now and not 12/12 ....its 2013...we have autoflowering femnized seeds...and LED's that put out the same amount of light as an HID for the fraction of the electrical cost and high heat.....as far as light cycle.. i would imagine every possible combination has been eperimented with. ..dont waste time trying to re-invent the wheel lol....and i dont mean that in a negative way at all..without experimenting half of the huge leaps in marijuana cultivation that have taken place over the last 20 years would never have happend.....glad you started the discussion and hopefully someone will pop in here who has solid information or reasearch on this....just my opinion

when i first started out, i would go from 12/12 to 13/11 to 14/10. just trying to do what comes naturally as the days get shorter. then i read that it actually hurts yeilds and to just go for 12/12. which is what i do.
every few years someone does some wacky lighting trick. they usually make one thread and are never heard from again.
7 days in cloner.. but i digress...

Balzac you know what else I noticed that I just remembered..... The root development after the switch to lighting is huge too. When I run 12/12 my roots are packed full in a 5 gallon bucket. On a 10/14, the roots were lame. Lame to the point to where I knew ahead of time that I wasn't gonna get the same result as the 12/12

4 hours dark, 4 hours light repeated will hurt flowering.
In fact, your plant(s) should stay in veg.
Research the 12/1 light cycle.
It's used to keep plants in veg.
It's like 12/12 but the 12 hours of darkness is broken up by 1 hour of light.
That means 12 hours light, 5.5 hours dark, 1 hour light, 5.5 hours dark. Repeat.
If 1 hour of light in the middle of the dark period is enough to keep a plant in veg, it stands to reason that the plant will also stay in veg at 4 hours of light and only 4 hours of dark, repeated.
Try it, see what happens, and tell us.

So the 4 hours of darkness makes the plant think that it's really closer to the 18/6 than the 12/12 schedule? Interesting. Now you guys have me interested in the science of it all. I'll see if I can come up with some answers.
