11 hours day 13 night ?

[DM101]

I was recently at the Hightimes Cannabis cup and had the great pleasure of meeting DJ Short from DJ Short Seed. He advised me to try a 11/13 when flowering instead of my usual 12/12. Has anyone tried this?

 

[charface]

Im on week 7 and see no difference.
Maybe his strains act differently.
I trust he sees something.

11/13 is what I use ...have done for years as its more convenient to me ..once you start stick to it or risk a herm ...is my thinking

 

[charface]

Dj mentioned different pheno expression.
And decreased electric bill.
I guess you cant argue with that aspect.

 

[StanlySpedowski]

I use 11/13. I didn't see any real difference between the two. So I stick with it really for the savings in electricity.

I tried this a few years ago after hearing DJ suggest it. I only did it for the last few weeks of flowering, hoping it would make the plants finish faster but I saw no noticeable difference.

I only grow landrace sativas so naturally I look for ways to harvest earlier. For my plants I've found below 8hrs of day,hairs receded and buds stopped developing.. ended up harvesting pretty much the same time doing 10-9 hrs as 11 but reduced yield and airy.. at 11 hr's my plants finished 1 week early. But I still harvested at 17 weeks soooo not too noticeable.....I would keep the quality and density up and not rush it
if i let my sats get root bound that speeds flowering by 1-2 weeks and yield is reduced slightly but bag appeal is still there

he has said certain things that i dont agree with

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 your 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 will have the best results you have ever had and save as much as 50% in energy costs.

I just started this light schedule as an experiment and I'm only in the veg stage right now and I will not start the flowering cycle for a few of more weeks. From what I can see so far I'm getting great results.

Now I've read from other growers with more experience with this lighting schedule and they say that using this method in the flowering stage there is very little to no stretch. From what I understand when growing 18-6 then going straight to 12-12 your plants experience light withdrawal and it's causing them to stretch trying to get closer to the light source. When using the 12-1 method your going from 13 hours a day in veg to 11 hours a day in flower which is only a 2 hour drop. So this means your plants aren't going through a drastic drop in light because they are use to the low light hours anyway and will not go through withdrawal and will not stretch much at all.


So only time will tell if this is going to be worth it but I'm willing to see this through till the end and come to my own conclusions.

Peace and keep em green.

I've had strains that flowered with 15 hours of light. Blue God, Kushage to name a few.

I know of a guy who changes spectrum
as he flowers to replicate more closely.
He runs a hydro store so he can afford it though.
Keep us posted on your progress if you get time.

ok so 12-5.5-1-5.5 compared to 24/7 under mh 400 i can see the difference that 24/7 just GROWS! i flower at 12/12 i will see how this new light cycle will do in the flower i gues depends what time i put em in, i wan thiking as soon as lights in flower tent go out throw em in so they get used to the shock of darkness for 12 straight hours and then light again and so forth.....

Can you tell us how long you have been doing this so far? I'm willing to give it a go, but I'm worried about early flowering. I have far to many plants in veg right now ready for outdoors this summer. I would hate to have to re-veg at risk of losing some.

 

[Dropastone]

My firs attempt. Just thought I'd pass on the info.

I think by doing a lighting schedual as this it would benefit with strains that carry color, like strains that are know for purple Buy having more off light time hence cooler temps for longer period of time , and if you have the means to add colder ambient temps during this longer off light time , I would bet you can get some really nice vivid colors on your bud .
