6/6/6/6 Light Schedule?

[Mader89]

I was told by a buddy I worked with way back that you can flower a plant with a 24 cycle being (6on 6off 6on 6off) for flowering. Any one ever tried or heard of this method. I don't have the room to experiment right now but soon.

why would you? that's stressful and = 12/12...

Since there isn't twelve hours of uninterrupted darkness, they won't flower.

It isn't stress in the classic sense, it's merely creating two summer day cycles in the same time span as one normally occurs. The plant won't care and in fact I intend to use this schedule for the last few weeks of my veg cycle to get the plants fully ready for bloom- and to accelerate the Calvin cycle in the quest for better roots.

Won't work. The hormone needs at least 2hours of darkness to become "active and then after becoming active, enough of it has to REMAIN active for a long period of time for flowering to be induced. Phytochrome is the hormone that cannabis uses to "tell time".

Flowering

Marijuana is a short-day plant. As the days get shorter, marijuana determines when to flower based on the number of hours it receives of uninterrupted darkness. It measures the length of the dark period using the hormone phytochrome, which has two states. The hormone’s inactive state, Pfr, occurs when it absorbs red spectrum of light at 666 nanometers. It also has a slight sensitivity to blue light. The hormone changes to its active form, Pr, over a period of two hours when the plant is in darkness. When the Pr flowering hormone levels remain high for a critical period of time over several days, the plant changes from vegetative growth and initiates flowering.

The number hours of darkness plants need to initiate flowering differs by variety. Sativas require a longer period of darkness than indicas because they developed near the equator, where the length of daylight is much more consistent than at northern latitudes, where indicas developed. Some sativas continue to grow vegetatively with 10 or 11 hours of darkness, which usually cues most plants to flower.

Many sativas initiate flowering only when the dark cycle increases to 12 hours or more, which occurs September 22 in the Northern Hemisphere.

By contrast, most indicas flower with 8 to 11 hours of uninterrupted darkness (13 to 15 hours of light). In southern tiers of Europe and the U.S., a few indica varieties flower as early as June 22, the shortest night of the year. For this reason, outdoor gardeners in these regions should consider sativa-indica hybrids and sativas. In the central and northern tiers, indica and indica-sativa hybrids usually start flowering in August and are ready to harvest in September through mid-October.

Some sativas and sativa hybrids require a longer dark period at the end of flowering to fully ripen their buds. Outdoors, this happens in due course as the nights lengthen in the fall. Indoors, change the lighting regime to 14 hours of darkness/10 hours of light to promote ripening. This is especially helpful in finishing low latitude varieties that don’t reach maturity in their native lands, where there is no winter, until the middle of the short-day season.

INDOOR FLOWERING

Flowering time of female marijuana plants is regulated by the length of the uninterrupted dark period, so gardens under lights can be forced to flower at any time

As ^^^ nailed it, why risk a room full of hermies just cause your buddy says...? Phytochrome needs to be established or else..!

This is almost exactly the same as 'gas lantern' timing techniques from the plant's perspective. The only difference is that it's arranged differently;

Gaslight theory would have us run twelve on, five or six off, thirty minutes to an hour on, and the balance in darkness, some five hours give or take.

This just rearranges things so they progress like short days. I see little risk of herm or lighting stress, certainly nothing like light leaks.

Green like money I've seen enough rude posts from you that don't have any insight to the thread. We are not here to put people down for their ideas, mistakes, or beliefs. Stay off of my threads from now on please I do not want help from you any more.

you have an ignore feature, so use it if you don't want to see his posts. but i advise you take his advice on this one. he isn't wrong.

Im not calling any body a liar or saying they are wrong I would just like to do it for my own personal experience ya know, assuming most people just have different views from what they have heard or read(why I asked in a thread to hear what they have heard). It's some thing I've thought about from time to time over the past 8 years an I wanna do it. I'm not gonna run an entire 1000w room to experiment that, I play on trying to make it a controlle. Seperated environments, t5s, one clone 12/12, one 6/6, and a seed(same plant) from 6/6. I check my plants daily so I hardly see a chance of some major contamination especially in there own little set ups. I'll do a journal when I do

Stupid is as stupid does. That's not advice

 

[cat of curiosity]

that would be fantastic. prove or disprove, good train of thought.

Thank you Cat, I wasn't calling the poster stupid, only the advice someone had given her. She has multiple posts tonight looking for additional answers to "tips" she has been given which are way out of line. Better to come here and get the truth than ruin a crop. Just sayin'. Find the ignore button.

i'm sorry mader, got the member/post mixed up. i was actually referring to vostok.

click on the member's avatar to the left, and you'll see working options, one of which is ignore. looks like he or someone else deleted that post, but, search his name, click the avatar, and click on ignore. you won't see any of his posts from then on unless you choose to deselect ignore in you user options (click your own name at the top of the screen)

that's true, and coming from me, it's going to sound crazy, but, ''you don't have to be a dick about it''...

unless it's deserved

i agree, it's like gas lantern. not ideal and unnecessary.

I'm not one to beat around the bush. You come looking for sound advice, sound advice is what you will get. If 6/6/6/6 was appropriate everyone would be doing it. No one is for a reason.

well stated and good advice.

This isn't logic, it's more like mob rule. Go where the science leads, and science has us try it and see what the results are.

My bet is that the plants won't flower, or if they express it won't go far. I'm thinking the plants will treat this just like gaslight.

Stupid is as stupid does. That's not advice

Well said and dripping with irony. Stupid is as stupid does perfectly describes this nonsense. Please stop calling these crazy ideas that go against hundreds of thousands of years of plants evolution "science" because it is not. Run this silly "experiment"yourself and then publish your results, don't speculate wildly about biological processes you know nothing about and then cry when people who know better chastise you. If you think you are alone in your despair, check out any defoliation thread.

 

[ttystikk]

My goodness, but people get cranky when you challenge their fondly held notions! Try it and see what you get.

I'll use it for veg, just like gaslight. I'll do it so I can run another room just like it on the flip and keep them both in veg/preflower.

It works or it doesn't, no gnashing of teeth or beseeching the heavens for mercy/permission required.
