An interesting question for you all!

Okay so if you're flowering on 12/12 then you switch to say, 10/14, the buds will mature slightly faster right?

How much degradation of THC and bud swelling would happen if you did this? Any sources for people who have done this?

At what point would it be not be worth doing this?

Im thinking of doing this but worried its going to affect the final product drastically. Any input would be much appreciated,

I think if you went to an extreme, like 10/14, your production might suffer, but I am doing 11/13 right now, and am happy with the growth, BUT.......
I don't have another plant side by side with 12/12 to compare to.

yea, hard to say, even if you made a 12/12 and a 11/13 to compare I don't believe you would see much different, I done it before and did go 11/13 for a week or so and ended up with 10/14 last week, nice end product, dunno if I got less, but I doubt it would be much ..

You would think more light would be better 24/0 for a few days, here's why. CBD is secreted into the stalked capitated trichromes UVB from the light source synthesizes the CBD --> THC, it can't do this in the dark, over time more CBD is converted to THC, trichromes becoming a clear amber, to amber as this process peaks, also converting the THC (to) CBN, if you knew when the peak CBD secretion took place you might be able to convert more CBD to THC.
if you could say flower the plant the last week under 24/0, I believe you'd see better results than giving the plant less light. And who cares if it starts coming out of flower, its getting harvested anyway. Opions?

"opinions"

Don't think it would work.I would have thought it's the dark period when the magic happens ,no dark period - no magic.Just stress ,revegging and balls ..

ON the 10/14 issue .. i believe it does speed up the process .I read a method some people use is to add half an hour of dark every 2 weeks until harvest.I have also read people say that while it speeds things up ,it's the light that is collected that is converted to weight ,so you are sacrificing weight for a slightly quicker finish.But then who knows whats right or wrong ,i always take debates and advice about scientific grow methods from stoners with more than a pinch of salt ,unless they are a proven master grower.Then i read one guy say "12 /12 works ,if it aint broke ,why fix it" .That struck a chord with me.

it is
CBG -> THC -> CBN
CBG -> CBD

the basic version. there is much more to it.

This sounds like an idea or hypothesis that needs to be proven before I would attempt it. I read a lot and watch others` grows along with videos and though I can state the fact that there are tons of great info out there, I must also state that there are some ideas or so called "facts" quoted by some people that I completely disagree with. My advice to you would be to try it for yourself. Do so with the same strain, same age and once the flowering starts, separate and examine daily. I can hardly believe that the gain would be worth the attempt but I have never attempted anything such as this idea of more darkness, light or whatever. Then again, this is all kinda new to me anyway so.....
Basically, what I`m stating is , give it a try and post your results. You may be on to something and then again, you may not.

"CBD acid is the precursor to the THC acids, and, although CBD is only mildly psychoactive by itself, it may act with THC to modify the psychoactive effect of the THC in a sedative way."
"(Clarke, Marijuana Botany)"

"Conversion of CBD acid to THC acid is the single most important reaction with respect to psychoactivity in the entire pathway and the one about which we know the most."
"(Clarke, Marijuana Botany)"

"
These cannabinoid acids are formed through the progressive degradation of THC acids to CBN acid (cannabinolic acid) and other cannabinoid acids.
"(Clarke, Marijuana Botany)"

"
One study used the three main compounds. THC, CBD (the biosynthetic precursor to THC) and CBN (the immediate degradation product of THC).
"(Starke, Marijuana Chemistry)"

I have no idea where you got that information, as I stated below and referenced several times. The cannabinoid synthesis (that is of great concern to growers) is
CBD-->THC-->CBN
-----
I personally don't believe either method (a dark period or a light period) would gain you any thing. It's a stale mate, the light degrades THC to CBN, or with no light CBD is never converted to THC.

IME I have found that reducing the intensity of light for the final few weeks helps to ripen the plant a little quicker.

I used to run 600w the whole way through until the final 2 weeks, at which point I would dial down to 400w.

From what I've seen with the same strains etc it speeds up ripening by a very marginal amount. A few days.

Now that I use a 400w I just keep that sucker at 100% on 12/12.

IMO if you properly care for the plant and keep it green until harvest you will end up with big dense buds that smell delicious and smoke great.

heres one. http://smokereports.com/cannabinoidsynthesis/
here is another. http://www.biologie.uni-freiburg.de/data/bio2/schroeder/Cannabis_sativa.html
here is a third. http://www.projectcbd.com/Availability.html

i can keep finding more if you like.

the book you are using for reference is 20 years old. marijuana science has improved.
everything growing is of great concern to me, that is why I make sure I have my information correct.


suppose I can give my input and be of more use to the thread itself.
my opinion is stick to 12/12. i saw the whole 10/14 thing going around for a while, people making claims. but it was all the same photo.
I searched around to look for people who did it, but never found a full grow. im sure that you could find one now, but at the time, I couldnt, and I lost interest.
12/12 works. and if it aint broke, dont fix it.

all in all i think you would be "working in the wrong direction". we use 12/12 because 12 hours of darkness is the min you can safety keep them flowering. Less dark time and they will hermi, less light time and you get less growth. If i could flower at 24/0 i would but nature doesn't support that idea.

Decreasing light hours ea week or two DOES work..but like others have said, you sacrifice yield.
I reduced light by 15 min a week from flip of 12/12 (next time im going to start reducing after flowering officially starts) and finished two 11 week strains in 7.5 weeks. The trichomes were mature but the buds looked like they needed mo time to fill in. Chopped em when the trics started turning amber (~20% amber)
I should say that im still pretty new to this growin game and was havin a few issues thru flower that may have reduced yield along with a very quick (3 day on accident) dry. Ended up with fluffy buds that tasted hay like but got chu really high :)

We use 12/12 because anything will flower within that light schedule, from exotic sativa to indicas.

Generally speaking it's a waste of time to vary from 12/12
