First pic is of new mother room with skylight. I will only be running my lights 10 hrs a day in here so no need to use 12-1. 2nd pic is AlphaDawg 34 days in and pic 3 is Jackberry X NYCD that looks like it is going to be one of the purple phenos. The final 3 pics are what I took down the last two days at day 56. I really don't have the energy to start arguing with some troll from Canada that just hopped in but my point of this thread was just to show this does work eh. I am making a bunch of seed runs right now so I have no idea how it affects the yield and everything is pure speculation at this point. I never said this was the best way to grow weed, I was just giving it a try. I also do not claim to grow the biggest buds, have the best weed, or have the best equipment. I make due with what I have and wanted to try and save some electricity as well as lower heat during the day. I can tell you that there were NO hermies and everything finished about a week earlier. And I don't know why when I rotate my pics on my computer they turn back around when posted. Irritates the shit out of me
Finally something worth my attention. You really have a beautiful grow. I would love to see you plants first hand. Really nice.

Y aknow i respect Uncle Bens opinion most the time... but am disappointed in his response... 12-1 is very much documented and very simple instructions. how is it people are saying no one knows what they are doing, or this is some made up out of the blue BS method.

a specific search on google for "12-1 lighting schedule" it xcomes up with 2340 results, regular search of 12-1 lighting schedule comes up with 75M results.
If you want to go with popular thought (in spite of the fact that the first poster contradicts your claims regarding Google search yields) then go ahead. Doesn't mean it's correct or the best way to go. If you're hard up for energy and can't pay for it, then you need to get out of the business. If you like playing up cannabis to something other than what it really is, a weed, then go ahead too.

It's all about photosynthesis as it relates to a plant's light saturation point and how phytochrome plays into the equation. Phytochrome, a hormone controls a plant's growing response depending on the amount found in the tissue. This isn't my opinion, it's botanical fact. Do your homework. Mel Frank explains it well.

these look beauitful, proof it does infact work. will be interested in final weight and your opinion as to wether it did reduce yield, your opinion will count for so much more as you have had the balls to try it.
also im sorry to hear for your loss brother.

I not in a business. I would think a significant number of people here are not in a business. But are trying to grow marijuana discreetly and efficiently. I like the size plant come out of veg, within the time frame I have. Everything I grow is for me, I don't sell it. Every expense counts for my medicine.
The plants are healthy and seem to show flowering faster. I will look at speed, quality and quantity when finished.

Lot's of things "work".

We discussed the lighting thingie on a solid botanical basis here. http://riddlem3.com/index.php/topic,3291.msg68825.html#msg68825

Let's look carefully at the presentation based on a solid foundation of botany. A plant requires a certain amount of light to produce enough simple and complex carbos to carry it thru to senesce. If you want to extend that time period out with weird lighting regiments, fine. http://www.theweedblog.com/how-to-use-the-121-lighting-method-for-efficient-marijuana-cultivation/

*****************************************
By Dennis Ford
......In a standard lighting scheme, we have all come to believe in basically one or two camps. I won’t get into who’s behind the whole “conspiracy” of keeping 12/1 out of the masses, but if you want to hear some good shit please see John P. RN (you know who!) or Joseph Pietri on Facebook.
Ah oh, bad start. We have a conspiracy, so they say.

I’ve found that for veg growth there are the two camps of 18/6 and 24/0 (18 hours of light
And then there's me that compromises both camps with a 20/4 during veg. And gawd does it "work" - https://www.rollitup.org/general-marijuana-growing/9114-spin-out-chemical-root-pruning.html

The fact is that all plants need a darkness period to process the days energy into food and growth. Therefore your doing yourself absolutely no favors using a 24/0 for anything other than cloning.
Wait minute. A cutting is a plant part with a unit (leaves) that produce carbos. I thought you said night time processes "energy" into growth? A plant is a plant, cloning or otherwise.

18/6 works on the other hand, but the truth is your wasting light. Its time to wake up! Its time to trick nature again!
No you're not. You're extending the food making process. Again, it's an issue of "at what point do we have a light saturation point?" and how quickly do you want to finish a plant maintaining the highest degree of cultural potential.

Truth is you really only need to break up the photosynthesis dark period with an hour of light to maintain veg, and in doing so you give the little lady a massive darkness processing/growth period. 12/1 is simply 12 hours on, 5.5 hours off, 1 hour on, and 5.5 hours off. Then repeat through your entire veg period.
Truth is you're restriking the lamp (HID's) so often you're reducing its life expectancy. The said light schedule (i.e. 1 hour on 5.5 hours off) will not produce the maximum amount of carbos a plant is capable of, so, you just extended the time of vegetation compared to someone doing a "more normal" 20/4.
Again!
12 hours ON, 5.5 hours OFF, 1 hour ON, and 5.5 hours OFF for each 24 hour period.
This is only for VEGETATIVE PERIOD, we have another simple process to follow for flowering.
Got it.

One of the obvious first things you’ll see is a significant drop in your power bill. Who doesn’t love that? But also your doing one other thing, breaking up the light period to prevent a multi-year footprint that LEO might find matches footprints they are looking for.
I guess if you're running a real large garden, it might be advantageous to extend the growing period.
FOR FLOWERING!
Flowering is simple as well, but its important during this delicate period in a plants life cycle to follow as closely what the evolution of the plant is looking for. Veg is different, the plant just wants to grow as big and lovely as it can. During flowering the plant is following a very specific genetic code for its conduct to continue the propagation of its species. This is why we adjust our lighting every 2 weeks.
That specific genetic code regarding a flowering response is controlled by the amount of phytochrome that is produced by the plant. With cannabis, a certain point is reached whereby the phytochrome is destroyed due to an internal flag dictated by a longer night. With the typical mutt, that could be 14/10 that triggers the flowering response, the standard photoperiod being 12/12. Any other period that provides for more than that is meaningless as far as phytochrome plant process controlling is concerned.
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.
You haven't accomplished anything other than delaying harvest. This guy needs to learn something about botany and what makes a plant tick. This is about as lame as folks using bloom foods exclusively during the flowering response which induces leaf loss and then they wonder why they ended up with popcorn buds and lousy looking plants.

Trust me, have a look at some of the pics below. These plants were all grown, in the various stages you see here, using these methods.
Smoke n mirrors. Correct me if I'm wrong people but he cherry picked a garden of young plants and then posted the top of 4" cola without any source of where the photo came from.

The fact that he doesn't use closely placed reflecting panels around the garden speaks volumes too. There's a 30% light loss workin' fer ya regarding the photons the garden receives!

12/1 works people, save yourself some money, and maybe just save your ass!

Big thank you to John P. RN and Joseph Pietri!
My ass is just fine. Maybe a little big at my age but rock hard with muscle gained from farming. :mrgreen:

still cant see the point of your posts uncle ben other then creating conflict ... i use the 12-1 and im not going to change .. you have your opinion i have mine .. i like the way my plants grow and they are healthy .. so no matter how many cut and paste jobs you do im still going to use it .. as are other people ... i do respect your advice on other matters, but in this one i will trust what i see.

happy growin

im seeing his negatvity but nothing concrete, for arguments sake lets say our posts are a stoners idea, theres nothing to say that yours arent of similar value?
as said when my crop is finished i will be the judge on if this works for me or not,
irrespective of how many flaws or articles you can cunjure up against it.
if i can save even a light cost and maintain decent output it will be a good thing.
and as a plant earth lover i would have thought reducing your carbon footprint would be a good thing too.

not at all i see copy and paste is a huge part of your life.
i would rather try for myself than dismiss so easily.

well azman ... like i said to lilbsdad ... trolls will be trolls .. there will always be people shouting your wrong because your doing something different and when you pay them no mind, they resort to making condenceding remarks ... i guess it just makes them feel better ..

Out of curiousity regarding the feel of this thread, I decided to click on page 10 and read a few posts, and......

Not if you're not actually saving electricity.
if you use less light you will get less growth... plants do not grow as well in the dark as growth is not an important life process. the less light you give during the day the less the plant will do when you do turn the lights off completely. so placing a plant on 20/4 should see faster growth than on 18/6.
if you're saving electricity then logic says that you are also losing out on growth.

Not sure why greenhouses would need to use a 12/5.5/1/5.5 light cycle when they use the sun to grow. they do in my country anyway... in a greenhouse you grow using the sun, you only use lighting during the night if you want to prevent them from flowering.12/1 does not actually exist. 12/1 to me suggests 12 on and 1 off, 12 on and 1 off, over and over again. this method is actually 12/5.5/1/5.5. Not sure what commercial greenhouses you've visited, but they certainly don't do that here.

**edit** ah scratch that... you've actually READ about them. I'd be grateful of links to these commercial greenhouses so that i can see for myself. thanks.
Someone gets it.

yep they are looking very nice .. i tried lst this time .. tied the stalk down .. seeing what the effect it had on the branching and flowering .. trying to keep them bit lower too

you tied them down? Where in nature does this happen, this is completely unnatural.

I posted this back on page 30 but i think it was over looked

i have herd of the 18 hour light schedule 6 on 12 off and that basically takes advantage of the plant producing and using light best in the first 6 hours of the day.......... it saves 6 hours a day they say finishes 2 weeks sooner with only a slight decrease in yield............and it makes sence

They won't answer, because they don't know.
They're just doing this because it's "cannabis forum knowledge" and can't explain why it'd be any better save for a few kWh of electricity.
We've been through all of this yesterday :)
