I guess you think I'm lying about vegging 14/10?Thats cool man I'm not here to try and convince anyone of anything,just to give my experiences not a write up from guy named Ed.It may be nonsense to you,but I guarantee I've said nothing false.

In 1954 two plant physiologists, H. A. Borthwick and W. J. Skully, were trying to find new
ways to improve crop yields and breeding techniques for cannabis. According to their
findings, when plants were exposed to daylengths of 16 to 20 hours, flowering was
incomplete and was greatly delayed. However, when they received daylengths of 18 hours and
were then switched to daylengths of 8 to 14 hours, flowering occurred in all plants. The
researchers found further that plants between three and five weeks old flowered within two
weeks after being changed over from 18-hour daylengths to 8- to 14-hour daylengths. The
five-week-old plants required fewer 8- to 14-hour daylengths than the three-week-old
plants to produce the same amount of flowering. One of the most interesting observations
related to photoperiodism was the occurrence of "intersexual" flowers on the
marijuana plant. They discovered that when plants were exposed to daylengths longer than
16 hours and then changed over to daylengths of 8 to 11 hours, the production of male
flowers on female plants ranged from 45 percent to 25 percent respectively for the shorter
daylengths. Also, the occurrence of male flowers on female plants that received daylengths
of 12 to 14 hours was greatly reduced or completely prevented. Another important
observation was that when the female flowers were pollinated from male flowers on the same
plant, only seeds that produced female plants resulted. Because of the female plants'
potency, this finding is quite valuable to growers.

OGOG OOGLE,I'm not even going to click that link if its just more shit written by somebody,DO IT YOURSELF,then call me a liar,I'm done.By the way,I started to read what you wroye until it turned into another "study".Studies dont interest me at all anymore lol,this is a do it yourself world bro,take whats written with a tiny grain of salt.ESPECIALLY when it comes to erb.I've seen the god himself Jorge say some of the dumbest shit I ever heard lol.I'm really done now bro,lets agree to disagree on how many hours a plant needs to flower indoors.

I will do that....
I may not go 14 -10 but Im willing to do my next batch of LUIs under 13-11.....
Experience only goes so far imo....
Ive known lots of people who have driven for 50 years and are clueless....
Once we are in a mind set there is nothing anyone can say to change that......
Have you ever watched the dog whisperer.....
his job is retraining thinking humans.....
Of some interest is that the two studies I posted they seemingly got two different results.....
The first was done in Brasil.... they stated they got no flowering from the sativas they used under 14 hours.....
the earlier study the most recently posted said all their plants flowered under 14 hours.....
I presume the difference is one of the strains used.....
no flowering for sativas under 14 hours makes sense based on its environment....
but to indicas.... 14 hours means winter is a coming......

Ceasar's my hero man,try 14/10 now I didnt say anything about 13 light 11 dark except I "think" the plants wont flower,they'll veg.I said I know from experience they'll veg at 14/10 that I do know.Maybe you should go 13/11.I say they'll veg they wont flower,not until you give them a full 12 hours of dark.

>>I dont see how a plant could possibly flower under 14/10 or even 13/11 for that matter
Waffeling??? LOL

Huh?Look man either we are mixing up light and dark or something,but your tone sucks dude.I dont think I want to talk with you anymore.I said what I said,umpteen times,I vegged under 14 light 10 dark and flowered the opposite,so WTF are you talking about??I dont see how a plant is going to flower under 14/10 or 13/11 only 12/12.Are you mixed up?Never mind man your taking me down to your level.You through the first barb long ago with that"I guess you've never grown outside shit.Like we were talking about growing outside or something.Then you come this morning with the sucky little attitude.I thought you were alright man,I thought wrong.And O yea your ooglebird wick cloner sucks ass too

Well, seems like I'll have to correct old Ed, just a bit. As Ed said, the flower cycle in a short day plant (Cannabis Sativa among other species) is determined by the lenght of the dark period. Most Cannabis strains originating in temperate zones will release their flowering hormones when the dark period goes above 10 hours (not 12), but this depends a little on the genetics.
Hormone levels within the plant do play an important part in flowering. For instance, if a seedling is put under 12/12 straight away, it will still vegetate for approximately 2 weeks before flowering, simply because the plant has not yet developed the right metabolism for flowering, and because flowering hormones are not yet present in the shoots.
Equally, plants can flower even if the dark period is below 10 hours. Some of you might have noticed that males can flower in late veg (the AK 47 is a good example of that), and females can also flower if they've been vegetating for a while. This is related to the build-up of flowering hormones in the plant.
12/12 is what a concensus of growers concider to be the best flowering period on a majority of Cannabis varieties, but some strains actually do better under 13/11. As said by some growers in this thread, 14/10 approaches the limits of flowering and should require extra time for most strains to finish, but it is possible.
Since the important thing with flowering Cannabis is the dark period (or so it was thought), some growers tried experimenting with prolonged light periods. For instance, I remember seeing a few reports from growers who went 24/12, in fact leaving out every second dark cycle, speculating that the plant can not make out the difference between a 12 hour light cycle and a 24 hour light cycle, and thereby gaining in light hours. I myself have tried 16/12 in one grow. The result of this was that in the first two weeks of flower everything seemed to go fine, but in the third and fourth week stress symptomes started to appear, and the health of the plants deteriorated. The 24/12 growers reported the same thing, stress symptomes. It can therefore be assumed that the plant's biological clock ticks in a way that it somehow can make out if someone's fucking with the light period as well. It's a smart plant after all...

Rosy when you say 13/11 do you mean 13 hours dark,ii light or the other way around?I take it as 13 dark,I wouldnt try and flower a plant with less dark hours than light.Sativa's do well under 13/11 thats 13 dark 11 light,I dont know of any strains that would flower well at 13 light 11 dark.So are we confused enough now lol?I normally go light hours first like 18/6 but with flowering I do dark hours first and maybe thats where the confusion is coming in.14/10 is a veg cycle to me,I never use it 15 /9 is the farthest I'll go if I'm trying to slow vegging plants,but my first grow indoors before I discovered the forums was 14 light 10 dark for veg then I just reversed it.I think if you gave a plant 13 light 11 dark,it would still veg until you gave it a full 12 hours dark in a 24 hour period,this is what I think I've never vegged 13/11,but I have at 14/10 and I know you cant get any plants to flower under that photoperiod.I'm not talking about preflowering AK's either,I know what you mean about that and its true genetics will play a part,but try flowering a plant with 11 hours darkness every day and tell me if it works.If it does then I'm just plain wrong.
No, 13 hours of light, 11 hours of dark. Light comes first, dark second, as in 18/6.

I have a little different way that I see the light dark cycle and flowering hormones....
I believe there are flowering hormones created in the dark and they are destroyed in the light.....
so once the plants are mature flowering hormones are created at night and they are destroyed in the light.....
However as the dark extends more flowering hormones are made and less are destroyed.... then at some tipping point the plant flowers.....
This is why I think 18 -12 doesnt work..... (or 24-12)
with 6 or 12 extra hours to undo the flowering hormones it tips away from flowering.....
In the same way as the folks who think they are cutting down the flowering by reducing the number of days by using 6-12
Whats really happening is by shortening the light cycle you are changing the ratio of these two balancing flowering/unflowering hormones....

In summary can the following conclusions be drawn (A. LANG, MSU-DOE Plant Research Laboratory, East Lansing, 1984):
In the leaves of plants is a hormone-like substance (florigen) produced, maybe also a complex of substances, that is conducted to the shoot meristems in order to stimulate them to pass from vegetative growth to flower formation.
The florigen is not species-specific. It can be transferred to members of the same species, to members of one genus and to members of different genera. The transferability seems to be limited only by the acceptability of the graft. A good connection between the phloem of the two partners seems to be important. Grafting of monocots are very difficult to do and a florigen transfer by grafting has not been successful, but it could be shown with other techniques that it is required in monocots, too.
Florigen is physiologically not specific. It can without difficulty be exchanged between short-day, long-day and day-neutral plants. It is very likely that it is identical in all plants. The main difference between short-day and long-day plants is that the florigen production occurs only under a certain (inductive) light program, that differs in the two types.
It seems that a likewise transferable substance exists in several long-day plants that is produced under short-day conditions and suppresses flower formation. It is called antiflorigen. The reaction is weak and cannot be detected in all combinations. Florigen and antiflorigen appear to be antagonists. The flower formation is mainly based on the ratio of the two substances.

Its hurts too much,I can't see the plant hormones even with my reading glasses lol.Just kidding folks I'm just going to stick with good ole 12/12 always leaning about 15 minutes extra dark,I'd never give more light than dark it makes me uncomfortable lol.If anyone gets a plant to flower and finish with a 13/11 photoperiod,please post the results.I want to see that it'll be an unusual strain I would think,if anyone can get a pl;ant to flower and finish at 14/10,I'll come over to your house and sign over pink slips to all my worldly belongings,for you will have to be a god in my eyes to pull that one off lol.

Are we or WERE we talking about growing inside?WTF is this dumbass thread being brought back for lol?OK bermyboy,flower me a plant indoors at 14/10 would you please?Then bring back this nonsensical thread when your done.You know,I've already said a dozen times on this piece of shit thread I've VEGEED on a 14/10 photoperiod,try flowering with one,either I'm not being believed in which case why do I fuckin come here every morning?This whole thing has gotten ridiculous.Are we talking about growing erb indoors or wTF will flower at the 8900FFT fuckin parlallel!
