Is 12-1 lighting scheme worth it?

Here is an article I found several places online:

Grow Bigger and Better,Saving 30-50% on your energy cost!

By Joe Pietri

The biggest innovator in the history of cannabis in my generation is Reinhard Delp. Not only did he invent and holder of the patent for ice water extraction, he has been building flower forcers since 1992. His new solar powered Sun-gate is the leader of the industry. He was the first to feminize seeds and sell them in Europe in the late 90’s. His process was done naturally, without the use of any chemicals.

No one is more copied but seldom matched than Mr. Delp, who to me is the top grower of our generation.

The first time he impressed me he showed me 2 plants, planted next to one another, 1 completely covered in powdery mildew, the other completely clean and beautiful.
He was developing mildew and mold resistant genetics.

In the late 90’s Reinhard brought back the gas lantern routine that you find in any college grade horticulture book, and applied it to cannabis. Cannabis needs only 13 hours to stay in growth state. The 18-6 lighting in growth pattern, actually stress your plants, that never get that much light in one-day outdoors. Cannabis is an outdoor plant. Growing indoors you should copy how it grows outdoors.

No Cannabis growing in Afghanistan gets 18 hours of light in growth pattern. Most strains today have some part Indica in their genetic pool. Even equatorial strains don’t get 18 hours of sun a day.

12-1 lighting is as follows: 12 hours lights on, 5.5 lights off, 1-hour lights on, 5.5 lights off, and repeat schedule. The 1 hour on in between off period fools the plants that stay in growth state!

Your immediate savings is 5 hours in energy costs daily, as well as your bulbs and equipment lasting longer. But how do the plants react to this lighting schedule?

You see immediate growth response from your plants, they are happy from the added rest time. By day 14 the plants tripled in size. The plants are bushy with twice as many bud sites without topping or bending, In fact, when you top and stretch your plants out, you get many more bud sites than you would have had under 18-6 using same procedure of topping and stretching plant, your growing bigger and better and faster.

So you're saving 5 hours daily in energy costs, as well as your accelerated growth pattern which also saves you time and energy and equipment use.

In the growth cycle, never use 12-12, start your flowering period at 11 hours on 13 hours off. When your are growing outdoors each day you get less and less sun light, you should copy the way the sun acts naturally in your indoor grow. So first 2 weeks of flower you go 11 on 13 off, the next 2 weeks you go down to 10.5 on 13.5 off, next 2 weeks 10 on 14 off, next two weeks 9.5 on 14.5 off and the last weeks of flower you should be at 9 hours on and 15 hours off. You’ll get bigger and better buds by copying the way the sun light works on cannabis outdoors.

Cannabis is an outdoor plant and you should copy the way it grows outdoors indoors. The only thing that 18-6, and then 12-12 do is make the energy companies rich as well as the people who sell lights and equipment, the more you use the more you spend. 12-1 is a more natural way to grow indoors and you well have the best results you have ever had and save as much as 50% in energy costs.

Something to think about for sure but would only work if you are doing your flowering plants in batches. Many growers do, so anyone want to try this and get back to us?

Might be good for folks who have smart meters hooked up. Not so likely to flag suspicious energy usage patterns and if it saves a buck so much the better.

Is this even real? Is it better for my plants? I see the obvious savings in electricity, but I've invested almost $3000 in a new grow...do I want to mess with this, or should I just continue as planned with 18/6 and 11.5/12.5 respectively.

I use 12/1 to veg with but primarily for the savings. It does have an interesting effect on cannabis, (bushiness), but some strains like it more than others, i.e. my Blue Cheese requires more time in the veg cab than my Super Lemon Haze does to get a decent yield. If I were you I would stick to 18/6 for now then try it after a grow or two to see the difference.

Take Care and Happy Growing!

Edit never ming this is dumb.. Dude is like in nature pants never get 18 hrs light.....the sun don't come on for an hr at night either....

No where in nature will you find "12-1 lighting" and most certainly not on a repeating diminishing schedule.
absolutely amazing what will be published just to make a buck.

what i have seen of this method is for triggering flowering in tough to flower sativa's
in the more common hybrids/indica's, i'd think it's a hermie formula

Something like this is actually used in the greenhouse\horticulture industry to simulate longer days to prevent the flowering of short-day plants. Poinsettias, for example, are [typically] short day plants just like Cannabis, and a technique like this would be used to control exactly when the plants bloom in the greenhouses so they will be ready for the Christmas season. It is called night-interruption.

Of course, there is nothing really 'natural' about it and from my understanding the interruption period is usually a bit longer than an hour, but night-interruption is in practice in the real world.

^^^One could probably cut that hour in half or less if you use Far Red spotlights that contain plenty of 730nm light. I've been led to believe that the light on period is just converting all the PFR to PR to keep the plant from flowering so 730nm should accelerate that process, though I've never wanted to mess up a grow to find out :).

I find all this fascinating. It seems credible based on some examples you all cited. I'm nervous about testing this. What I should do is take a few CFLs in a box in the closet and test it on a plant or two for nerdy fun. I doubt I would subject my 20 plants to something other than tried and true lighting patterns.

actually thats backwards. the Far red at end of light cycle is to allow for a shorter dark length, to promote flowering. ie so you can use a 14/10 instead of 12/12 for flowering.

What Nullis says is correct, The 12/1 is an interruption of the dark cycle to simulate long days without providing light for the whole long day period. Its really designed for large greenhouse operations where profit margins don't allow for extensive artificial lighting. Personally I would rather veg 24/0 or 20/4 and grow faster.

Greenhouse is the only kind of operation that comes to mind where something such as this would be practical. With Cannabis it does seem to me the plants would stretch more\grow slower.

There is nothing "natural" about growing un-pollinated female only plants to harvest the trichome covered false seed pods in order to ingest them and get high.

I would argue it is more natural than not for the sake of the fact that you can't grow unpollinated female plants to harvest under water, or in a vacuum.

the hight of the summer where I live is about a 15 hr. day so thats like 15/8 v.s 18.6 hmmmm 18/6 seems more natural than 12/1/5.5/15.5
