I came across this blog today. How To Use The 12/1 Lighting Method For Efficient Marijuana Cultivation | The Weed Blog I was wondering if any of our growers have tried this. It sounds too good to be true. So any of you "experts" using this method or at least tried?
Hmmmm I guess of the 400 plus people who viewed this no one has tried it. I guess I'll hold off for a while trying it as well :thumbsup:
This does have me intrigued and I see nothing wrong with the logic of using it in my veg tent. I have of course never tried it, but will soon. I have ordered a new X-10 computer based light timing system, and will soon be able to have much more control than one single simple on and off time.
There's another thread where someone is trying it. http://boards.cannabis.com/indoor-gr...roach-veg.htmlQuote:

I guess every question has been posted at one time or another ... guess it's time to close the board (just kidding) I didn't realize there was another discussion about it here silly me should have known better
My X10 system arrived yesterday. I now have an insane ability to manage my lights, fans, pumps... everything, via a home computer management system. This is totally awesome! Just as an example of how versatile this system could be, it would be a simple matter to have the computer exactly simulate the sun outside, automatically varying the length of days with the season... Not that we would ever do that in our tents, but just saying. :) For now, my living room lamp now knows to come on 15 minutes before sunset automatically. Way cool.
Anyway, today has been the first day of 13/5.5-1-5.5 in my veg tent. We shall know in a week or so how the plants are responding to it as I have several clones, one late veg bush and a batch of real edible strawberries in there. It is obvious that a lot less power is being used now compared to the 18/6 that this tent was on, and if this works, it will wonderful.
Let me know how this works for you . I want to save money as well.
OK... it has been enough time to make a decision regarding this 12-5.5-1-5.5 method. I have been using it for enough time to see if the plants would go into flowering mode from this odd lighting pattern, but I see no signs that this is the case. Quite the opposite actually, I am seeing aggressive vegetative growth in the tent now. Everything in the tent seems to be going nuts with growth and I see no problem with this method at all. I will let you all know if this changes in the future, but so far... this is a success and I am saving 5 hours of electricity every day. Nice.
awesome news emily I may have to try that with my white widow grow (starting the seeds soon)
DON;T fall for that crap man Cannabis uses C4 photosynthesis, so is not dependent upon a night cycle for carbon dioxide absorption. A cannabis plant in the vegetative growth phase of its life cycle can thrive under twenty-four hour daylight conditions, although some growers advocate a small rest period to avoid overstressing the plant. Flowering usually occurs when darkness exceeds eleven hours per day and can take up to six weeks.Quote:

Dr... no one was talking about ph. No one was talking about hydroponics.Quote:

So then in your attempts to sound erudite you mention that flowering can set in if darkness exceeds 11 hours per day and for anyone not paying attention you state that this flowering can take up to 6 weeks. This is the point that my pontification alarm went off.
Dr... first of all, most strains do go longer than 6 weeks... some of mine recently have gone as long as 9 or 10. This however is not why I stress as I write these words. The entire point of this thread was that we were attempting to trick the plants... to be able to give them a longer darkness period and save the money for lighting, WITHOUT PUTTING THEM INTO FLOWERING MODE. Please understand that we are not suggesting here that this is the proper way to grow cannabis... it is a trick... and experiment. Your comments did very little to further the dialog in this thread and thus has resulted in me being a bit testy in my response to you. I think it was the way you started the note that set me off... "Don't fall for that crap"... hmmm... was it my crap that was offending you sir?
first off messing with lighting schedules 99 percent of the time will cause stress , hermies, as well as poor growth rates, I think why people are thinking of going this route is to save a dime on there electricity bill and possibly heat issuesQuote:

you mention tricking the plants Ha i would really love you to explain how to trick a plant ?????
To Get best possible growth / yield you need a dialed in room running proper hrs for photosynthesis that is the building block of life period and yes marijuana is a dark period plant meaning darkness triggers hormones to flower some plant types use temperature to change to flower Wheat ETC
Bottom line to get best possible yield one must think and do like mother nature as fall approaches daylight lessons so in reality as you get into late stages of flower it is a good idea to to lower light periods from 12 /12 to 11 / 13 / 10 / 14 also reducing temps
6 weeks ? what planet are you growing this weed on? I'm at 6 weeks now with at least another 4 to goQuote:

HAHAHA please where does it say i mention weed finishes @ 6 weeks i never once even mention 6 weeks ??????Quote:

Your just looking for trouble doing something like that ??? looking at electrical savings what are you actually saving here ??? are you trying to tell us that going this light schedule your going to gain in yield ????? i beg to differ only people doing this is probably closet growers worried there mama is going to see a difference in the power bil

We are not advocating using this weird lighting method in flowering... only in veg. Most everything you have said here has absolutely nothing to do with what we are talking about. Your interruptions in our conversation are annoying at best, and I wish that you could not only stay on point, but I also wish that you would not attempt to denigrate and insult those unlucky enough to happen upon this thread with comments such as "their mama" and "don't fall for that crap". My goodness dear Doc... smoke some of the ganja and mellow out dude. Why are you insisting on fighting about this?
Not getting into the thread argument here, as I feel its moot and should be dropped, but here are two bits of advice following the current topics:
60 day wonder is 60 days from seed to harvest, its a mid level, but it still produces quickly.
I wanted to touch on the lighting gear as well, the brinks computerized timers run from 9 to 14 USD and can be set for 6 different cycles, I currently only use 18/6 veg lighting, but have the ability to do 12/1 etc
very cool! Thanks for the info on the brinks timers. I have one that I was not very impressed with however. It has the ability to change state every 15 minutes, but sadly broke shortly after turning it on. I will have to take another look at their line however after reading what you have said here.Quote:

I am not trying to be a prick just bringing in some common sense ???? In nature, cannabis plants (excluding ruderalis) begin to flower in the late Summer and early Fall. When the days start to become shorter and the nights longer, flowering signals are triggered by photoperiodism, beginning the flowering process. The increasing hours of darkness signal to the plant that Fall is just around the corner. The female marijuana plant shifts its energy from vegetative growth into flowering, in order to attract pollen and produce seeds. By manipulating the hours of darkness, indoor and outdoor growers can delay flowering indefinitely or begin flowering whenever desired. yea under stand ??? so by playing with light schedule what are you really playing with plant hormones ??? the plant doesn;t know whats going on so what are you really doing ??? other then stressing a plant out.
I really hope you under stand a healthy plant is what you want in order to get maximum yield out of it that is what its really about Right ???
Cannabis plants are referred to as long night or short day plants, because they require a long period of darkness to trigger the hormones that tell the plant to switch from vegetative growth to flowering. These light receptors are color pigments in the leaves called Phytochrome Red (PR) and Phytochrome Far Red (PFR). These pigments get their names from the types of light they absorb. PR absorbs red light between 660 and 760 nm and PFR absorbs far red light between 760 and 800 nm. These two pigments chemically react to the light, and trigger the plant to flower or not.
This is where it gets a little confusing.
In cannabis plants, the normal presence of PFR switches off the flowering signal. The level of PFR is what you can manipulate by adjusting the photoperiod. PFR is quickly produced when plants are exposed to light that contains far red wavelengths. When there is light, the PFR and PR maintain a balance. When the sun goes down or the lights go out, the darkness gradually switches the PFR to PR. Because of this, PR levels gradually increase and the PFR gradually decrease during the dark period. The presence of PR is a neutral condition to the plants and essentially tells them nothing. When the light returns, or if a small amount of far red light interrupts the dark period, the PR immediately switches back to PFR. If the plant is without light long enough, the PFR will decrease past a tipping point. This decreased level of PFR signals the plants that Fall is approaching; and the plant begins flowering.
In short, the presence of PFR due to long hours of light and short hours of darkness keep the plants in the vegetative phase. If the plant experiences enough hours of darkness, most of the PFR turns to PR ; and the low level of PFR signals the plant hormones to begin flowering.
On closing note *** would love to see 5 week veg girls with that light schedule bottom line there not going to be that great here 5 week vegged girls from a 3" clone would you look at the stalks on them girls going into 6 weeks ???
Aynways Good luck there emilya i am not here to dictate how you or anyone else grows , just here to help growers achieve better results , You have to sit back for a moment and think of this ok
Some clown comes up with a crazy light schedule scheme not knowing really anything about Botanic's and how actual plants work???? and Yes some people fall for it.
Hey its understandable were only human Jones town ring a bell ???? but anyways obviously working on a Dime expense
Then on the other side of the spectrum you got experienced growers well known Cervantes, Heath, Soma ,, you name it guys with actual experience and knowledge you would think after years and years of growing they would of caught on with this scheme ???? and somewhere wrote in there books which many call the MJ bible But its not there and for good reason
Anyways looking forward to your updates if you got any ???
