During the light cycle your plant produces a hormone that suppresses flowering. This hormone is slowly depleted during the night cycle. When it reaches a low enough level your plant starts to flower. By having a long dark cycle you remove the hormone faster and reduce the flowing time period needed for a finish product.

I've heard this and variations on it many times before. I'm curious if anyone has a legitimate scientific paper or research article to corroborate this in cannabis plants, though, because I've never seen it mentioned in any way other than anecdotally.

Aren't we trying to emulate nature in our rooms?

Pretty sure you want that hormone. Sounds like it helps regulate the growth allowing the plant to for lack of better terminology, mature where it needs to, so that it is ready for bloom on its own accord...

very interesting, do you know which hormone is in question?

damnit krunch, sure there is a buncha bullshit shenanigan shit-talkery going on in this thread, but u can't leave ur icmag peeps hanging like this.... wasup w that GDP tray?

bigups to you for showing the good the bad and the ugly in this thread, and most of all the learning experience...
hope all is goin well for you, and im just curious as to your progress/outcome on this project... are you going to continue w the tables?

I don't know the name of it sorry.

I am not trying to emulate nature in my rooms. I am trying to get the most production I can with what I have. The hormone stops the setting of flowers. When I place my plants into flower I want them to flower.

As for having a paper sitting it I do not have one. Maybe someone else does. I can only go with what I have seen in my own grow. And that is faster development of flowers.

I'm pretty sure you are referring to auxin. Auxin is suppressed by light, and root growth is the primary focus. Auxin increases in the dark cycle, suppresses root growth, and stimulates shoot and bud growth.

Get your facts straight grobro.

What a read

What a read

It took a while but I read the whole thread... Respect krunch for laying it all out there and enduring a shmeckling of shit n keeping going. I'm not going to try and give u technical advice or point out faults, I just wanted to give you props for putting up with the BS . I use an rdwc myself and have learned tons from Snype postings here, if your looking to replace the tables n like scrog growing make check em out. Only question I have its what's the next step moving forward? Grab them bootstraps n pull hard man, best of luck to you. I'll keep watching

72 hours jump starts flowering, but by how much? I get flowers starting in 9 days after 12/12, can you get flowers in 8 days or 7 after turning the lights back on? not being critical just trying to understand the logic.

Just curious what the standard is for bud set. Are u talking first view of pistils, or pinky size bud set. I always have the pinky size bud set In my mind when we talk about being able to see the start of flower.

I'm going to echo jobesb. I've seen flowers a week after going from 24/7 lighting to 12on/off... even with an Acapulco Gold cross.

I mean buds the size of my thumbnail. Or the size of a Nicole.

I get those tiny hairs but I don't mean them. I get them in veg.

Phytochrome, a light sensitive protein chain, not a hormone.
Pfr reverts back to Pr during night cycle. Florigen is the name given to what is believed to be a group of hormones/molecules that control/initiate flowering. Not to be confused with the name of what appears to be a snake oil product.

Idunno about the 72 hrs thingy IMO your saving 36 hrs of electricity, losing 36 hrs of photosynthesis ( growth )
lets face it plants are changing from veg to flower so the first week really its still growing at a rapid speed , as if it did in veg . and that is why many nutrient lines mention adding both bloom and veg in first week then backing off to straight bloom this also helps when most people see yellowing to quick 3 - 4 th week of flower cause plants used up all the N to quickly in the first 2 weeks lol
i can see leaving lights off to adjust to different 12 hr start time time???? i have left my lights off for just that . 18 /6 left them off for 12 hrs so lights went on 9 pm to 9 am colder night temps etc
but to each there own IMO leaving lights off for extended periods in later veg humidity becomes a issue least that is what i find when you got bigger plants 5 week veg + and in soil
I also think that leaving plants in the dark for extended period of time plant uses more of its stored energy so battery is slowly dieing out leave a plant in the dark for a while and it will die so your using its banks YOUR STARVING YOUR PLANT when lights come on plant is working over time to fill up them banks again for use in bud development I would think not stressing a plant at this stage would be better idea also feeding plant what it needs is rather important Carbs etc to help it along
THats my though lol da hel with auxins or what ever us weed growers are also becoming MAD scientists lmao let the plant do its thing just like it has for thousands of years

New research shows that to prevent starvation at night, plants perform accurate arithmetic division. The calculation allows them to use up their starch reserves at a constant rate so that they run out almost precisely at dawn.

“This is the first concrete example in a fundamental biological process of such a sophisticated arithmetic calculation.” said mathematical modeller Professor Martin Howard from the John Innes Centre.

Plants feed themselves during the day by using energy from the sun to convert carbon dioxide into sugars and starch. Once the sun has set, they must depend on a store of starch to prevent starvation.

In research to be published in the open access journal eLife, scientists at the John Innes Centre show that plants make precise adjustments to their rate of starch consumption. These adjustments ensure that the starch store lasts until dawn even if the night comes unexpectedly early or the size of the starch store varies.

Professors Martin Howard and Alison Smith Professors Martin Howard and Alison Smith

The John Innes Centre scientists show that to adjust their starch consumption so precisely they must be performing a mathematical calculation – arithmetic division.

“The capacity to perform arithmetic calculation is vital for plant growth and productivity,” said metabolic biologist Professor Alison Smith.

“Understanding how plants continue to grow in the dark could help unlock new ways to boost crop yield.”

During the night, mechanisms inside the leaf measure the size of the starch store and estimate the length of time until dawn. Information about time comes from an internal clock, similar to our own body clock. The size of the starch store is then divided by the length of time until dawn to set the correct rate of starch consumption, so that, by dawn, around 95% of starch is used up.

“The calculations are precise so that plants prevent starvation but also make the most efficient use of their food,” said Professor Smith.

“If the starch store is used too fast, plants will starve and stop growing during the night. If the store is used too slowly, some of it will be wasted.”

The scientists used mathematical modelling to investigate how such a division calculation can be carried out inside a plant. They proposed that information about the size of the starch store and the time until dawn is encoded in the concentrations of two kinds of molecules (called S for starch and T for time). If the S molecules stimulate starch consumption, while the T molecules prevent this from happening, then the rate of starch consumption is set by the ratio of S molecules to T molecules, in other words S divided by T.

How many plants in those thousands of years, dug themselves out of the ground, walked inside, cleaned off their roots and jumped in to a bath of nutrients?

I never understand why people banter that statement around as if it made sense or had merit. It was gibberish the first time someone blubbered it out and still is.

The article you posted is gold though, enjoyed reading it again.

(This text is Edd-Rosenthal )

One way in which plants are categorized is by the way they gather and handle carbon dioxide. Cannabis is a C3 plant. It uses the CO2 it gathers during the light period, when it is photosynthesizing. Plants designated C4 also gather CO2 during the dark period for use during the light period.

Many C3 plants, including cannabis, do not need a rest period. They continue to photosynthesize as long as they are receiving light.

The plant's photosynthetic rate determines its growth rate because the sugars are used by the plant to build tissue and for energy. Cannabis under continuous light will grow 33% faster than the same plants on an 18-6 light regime.
