If that was true ? Then why don't ALL plants do it ?
Some may be able to handle more UV than others most likely equatorial sativas can handle UV the most, or strains that originate in the mountains like PCK . I can tell you right now early amber is fried trics from UV, i did it when i first started using UV lights in my garden and ran them too long, fried a lot of the trics on my golden goat early. Shit was super sedative, too much CBN.

Sorry but nothing I grow is sedative, not even land race Indicas

Well that sucks, i love a good bed time smoke. Also sedative strains help with pain relief. If you need some strong indica let me know i got some strains i am working with that will put a rhino down. Just a fyi if you didnt know UV is harmful to plants and humans. It stresses your plants, and shouldnt be used until at least week 2 flower, 15 minutes per hour starting mid day. And that's a fact that was published by a university.

Not if I grew it 8)

If you say so lol

funny thing was when I stopped carin bout yields, my weed got way better

And I know you just spent a week gettin bashed over you curing tech brown buds (which I agreed with by the way) so bash away, doesn't bother me. I'll keep doin what I do and you do what you do
Well that's a good attitude anyway. Your weed, you can harvest early if you want. I don't believe the gaslight has any advantage over normal veg cycles, that's all. It might take a day or 2 off the time it takes to induce flowering, since long photoperiods are known to inhibit induction by a couple days and your cycle is actually a short photoperiod of 12 hours followed by an even shorter one of 1 hour. My 6/2 cycle accomplishes the same thing and I suspect produces more rapid growth than your 13 hours per day cycle. You never tried 6/2 so you wouldn't know. I don't know why you would chop before the most productive weeks though, after all that setup time that led up to it. Maybe you have too much weed or something.

is that 6 on 4 off 2 on? ill give that a shot if so.

Sure there's less stretch, because there's less growth. Faster finish? Get real. You can SAY I'm wrong, but where's the proof? Why has no article ever been published saying that anything ever grown in a greenhouse with the gaslight had it's finish sped up? I find it rather unlikely that you found an effect of night interruption that has never been noticed by any scientist before in the history of greenhouse horticulture.

He's written several articles over the years.
Julien turnois wrote a book about this very topic in 1910 called reaching for the sun.
Probably not long enough ago to be taken seriously I'm sure.

What a bummer! What lighting do you use? Could there of been any other factors that would of played a part do you think?
In short, yes. Lighting was 315w LEC/CMH. The plants were in aero, and the reason I switched to GLR was to keep heat down to help with getting root rot under control. However, while on GLR, I had a harder time than usual fighting off the rot, and the growth of the plant was noticeably different than when on 18/6. The plants were bursting with preflowers, internode spacing was very compact, all leaves were basically miniature versions of their 18/6 counterparts. Although the root rot didn't help with the vigor, those issues are not symptoms of root rot. After nearly two months of crap growth, the GLR was abandoned, plants moved to soil where they've been revegging.

Rooted cuttings headed into GLR.

The Turnois book merely mentions that an interruption in the middle of a 16 hour night prevents flowering, which is well known. I found an article abstract that says night interruption will reduce stem elongation and increase branching, so that much may be true. That's with sun grown plants though. The day extension or night interruption with electric light of with lower far red content than the sun will reduce stem length.

Since RM3 grows with fluorescents rather than sunlight I doubt there would be any difference from the night interruption. It's the exact same spectrum. And notice that it says the same effect is produced by extending the day with low far red light. So a longer day produces the same effect, like 18/6. It all only applies to greenhouse growing, where you have a short day problem in the winter months. I don't think it has an effect of speeding up flowering later when 12/12 is used though. And btw you could get the same effect as 12/5.5/1/5.5 by 1 minute of light in the middle instead of 1 hour. So you could use 13/11 with a one minute interruption in the middle of the 11. You don't even need an hour so what's the point? If more darkness increases growth then why would you not use 12/12 with 1 minute on in the middle of the night part? You'd get 59 more minutes of dark.

"Elongation of plant stems, flower stalks and leaf petioles, lateral branching, shoot and leaf orientation, and leaf pigmentation are influenced by both light quality and temperature. Morphological responses to light and temperature are referred to as photomorphogenesis and thermomorphogenesis, respectively. Red light (R) or light with a high R/FR ratio (e.g. fluorescent lamps) applied as day-extension or night-interruption (NI) suppresses stem elongation and promotes lateral branching. Far-red light (FR) or light with a low R/FR ratio (e.g. incandescent lamps) strongly enhances stem elongation and inhibits lateral branching. The DIFference between day temperature (DT) and night temperature (NT) defined as DT minus NT = DIF strongly influences internode length and plant height in a wide range of pot and bedding plants, while average daily temperature only slightly influences internode length. Plants grown with a positive DIF (DT>NT) are taller at maturity than plants grown with a negative DIF (DT<NT). The response to DIF is quantitative. For many morphological characteristics, thermomorphogenesis is similar to photomorphogenesis in the following manner: 1) R light (high R/FR ratio) = negative DIF, 2) FR light (low R/FR ratio) = positive DIF. In the long day plant (LDP) Campanula isophylla, DIF interacts with lamp types (high R versus high FR) which indicates that DT/NT alternations interfere with phytochrome mode of action. Leaf unfolding rate and flower development are not affected by DIF, but by average daily temperature. Incandescent (FR) and fluorescent (R) lamps are almost equally effective in promoting early flowering. in some LDP. Incandescent lamps, however, cannot be recommended as proper lamp type for photoperiodic lighting to induce flowering in LDP if compact, well-branching plants are desired. Lamp types with a high R/FR ratio should be used. Practical application of DT/NT treatments and light quality manipulations with different lamp types and time of applications, including elimination of twilight or selective screening of the daylight spectrum, will be discussed."
