... y u be likin the posts from the mean person ...
No one said you were mean - this isn't personal.

I simply disagreed with the theory the video espoused - from hands on experience.

I also disagreed that the theory espoused is a game changer - again, from hands on experience.

Please - grow with the 10/14 cycle if that's your desire. Good luck with your crops man.

this video is game changing for indoor growing wow. minute 17 is about the effects of different photo periods for flowering indoors. the scientist has all slides and pictures of his experiments and holy shmidokes, across three strains the 10 hour photo period flower was way better and with quicker finishing time, and only traded for a marginally smaller yield. some other paradigm shifting info on here also

Lol, I could of told you 10-14 will give you a faster finish with less yield 30 years ago. Dont know about more potency with the types most people are used to growing. Though the more sativa/tropical types types will defo give better bud ,beter results, beter finished flowers that are more potent under 10-14 as the flowering response is stronger. You can even veg them under 13-11. But if your talking about plants made for indoors more indica leaning types your beter off sticking to 12-12 for flower and 18-6 for veg, decades of experimentation from millions confirms this.
By the way did he test multiple of the same cuttings over and over in the same conditions bar the light hour change, cus if he did can someone put up the pics. I can just see one plant for each light hour diffrence , who knows if he picked the heaviest yielding one to make the results look as they did. By the way no13 isnt as ripe as no10, the plant hasnt reached the same stage as no10 so his experiment is flawed cus he probably dont understand this.

all good i was a bit amazed when i first watched maybe it was the live chat that added to the ferver(?) cheers

Fwiw, some guy in the "TGA by others" thread does 6 on/18 off for flower and says it works just fine...I don't think his flowering times are cut in half or even close to it, though. There was also a journal here a few years ago by someone running 8/16 for several cycles...
interesting nice

seems like it was a legit type of university and/or institutionally funded study. he talks about three strains overall in the different experiments but i think only uses examples of two of them (sunset and og) for the photoperiod studies since they did better at 10/14

assuming there is no intentional skewing going on, those pictures have me trying this on this next crop for sure i mean why not(!) this is a chart to summarize the overall findings

Good to know...thanks! (For context, this worked great with SSH and OGKush) I did the gradual half hour reduction every two weeks, after the stretch.

That chart dont make much sense, as it dont show were the finished ripe plants are more potent under 10-14 vs finished ripe plants under 12-12. It also dont show the yield of finished ripe bud under 10-14 vs finished ripe bud yeild under 12-12 wich are all the things that maters. An then in the pictures it dont show you the results of each individual plant of the same strain cutting of something like 30 plants vs each individual plants of the same strain cutting again 30 plants. This would then have to be repeated something like 10 times for a experiment and results to actually mean something. Another thing did they veg them all for the same time cus on that chart it looks odd. From the chart it looks like the tiger strain was the same at 12-12 and 10_14 but the other strains weren't, that would actually show that his experiment dont actually work as they are claiming. Maybe im reading it wrong, dont seem to be set out as a great chart at all.The science with cannabis is still in its infancy, the underground community as a whole and growing literally billions of plants over 50 years is far far ahead in getting the best yields out of cannabis and pushing the potency taliored for smoking and other human use. Ive seen some of these scientific grows and pharmaceutical grows, and some of them are bad much like the plants in the 70s flowering under florescent tube shop lights.
By the way I actually grow on 10-14 myself cus I grow mostly heavy sativas. But if I was growing more indica types I grown them on 13on and 11off as it gives slightly more yield, no change in quality and potency and takes a couple of days more to finish. But the plant ends up harvesting over the course of its flowering cycle a good few hours of more light power. But I do those things because I understand indicas and sativas and how they trigger different, and the points at wich semi reveg recurs and the flowering hormones peak trigger points and how to keep them at the critical point enough to proced flowering still all with out efecting potency. Even autos (depending on type) I grow under 24hr light on they flower longer and throw out more flowering waves so produce more and come out more potent too.

i am not about to go cross eyed so i'll just say that he did mention the finish time of sunset (8 weeks) and the pictures are at 6 weeks and he said anything higher than the 10 hours group would not be as quality a FINISHED PRODUCT

he concluded from all the testing that after all is harvested the bud quality is better within the 10 hour group with an exception for og which benefited in yeild from raising to 12/12 FOR THE "LAST".....4 WEEKS OF FLOWERING(!)

google says og finishes in 8 wks, and here is that picture again of the ogs at 8wks....

but sure, bro science before literal phd studies institutional science ur right

I have never tried a schedule other than 12/12 for flowering so am not going to throw in an opinion, but I do find it humorous that you talk about bro science and phd studies (which are very often flawed,) then throw out a google search result as fact. Now that’s scientific.

ok... googled og kush and scrolled the first 30 or so results and on average i would say the flowering time "ACCORDING TO GOOGLE" (ron burgundy voice)

is 8 weeks : )

Did he grow them 10/14 for the entire flowering stage? Does the study include info on bud dry weight as well as trichome quality and actives?

I have no doubt quality goes up under 10 hours. Less cumulative heat, less volatizing of terps. But to say yield loss is marginal is nonsense. Assuming growth is for 10 weeks, thats 140 light hours difference. Please dude.

I think @torontoke was doing some work like this, low daylight hours.

if so few google results reflected real og finishing times then it would be more likely the og tested was of the shorter flowering type also

the gist of it is like, if 10/14 etc has this effect across multiple strains then you would have to assume that the plants that are noticeably further along earlier will be a better finished product when all plants are harvested from all test groups

that is what he was saying was the general conclusion of the photoperiod variation study and again by the photos there is no logical reason to want for a higher flower period if flower quality is not of concern.

also he said that they found og benefited from going 10/14 for four weeks, then RAISED to 12/12 for the last 4+ to increase yield

i think marginal is not that far off to describe the yield loss overall though if going by the photos. a lot more stem and trim as the photoperiods go up also

The approach is called the 12-1 lighting method. I started a thread of it here ---> https://www.rollitup.org/t/the-12-1-lighting-method-not-your-18-6.1092464/

And it works.. On my third grow of OG Kush the flower density nearly doubled under 10 hours of flower on time. The general way to go about it is listed here..

"When we begin flowering, move everything to 11 hours on, and 13 hours off. You will keep this for 2 weeks, then drop the lighting period by 30 minutes, I.E. after two weeks you will switch to 10.5 hours on, and 13.5 hours off. Continue this 30 minute drop every 2 weeks until you reach 9 hours on/ 15 hours off. Finish your flowering at this lighting".

I didn't have the balls to try 9 hours but kept it at 10 hours for the last 4 weeks of flowering.
I'm running a 9 on 15 off I'm 4 weeks in my buds are fat, can they mature too quick

Yeah, that would be me :) when I started this, it was 6/18 for bud for a few weeks but I found the sweet spot to be 7 on, 17 off. I’ve been doing it for the past 14 months. From my experience, it cuts my bud time down 5-8 days. Buds are just as dank and the same yield if not more.

And for veg, I do Joe Pietri’s 12/1 veg.(it’s not gas lantering either). 12 hours on, 5.5 hours off, 1 hour on, 5.5 hours off, then repeat. The hour on in the middle night stops the plant from going into bud and tricks the plant into having 2 nights of rest. The plant gets bushier too.

I’ll never do 18/6 veg and 12/12 bud ever again. All you’re doing is wasting money.

Go to 36:00 where Joe goes into the lighting cycles.
