18 HOUR (6on/12off) Light Cycle

Ok, so I was just introduced to this technique, and I was astonished.
I have spent the last 2 hours reading web threads and articles and would like to hear more.
There weren't that many people saying it worked, is this because most are commercial growers hoarding their great marijuana knowledge?
I'm skeptical still, the one garden I have seen in person using this technique was having reveg issues as far as i could tell. It was his first attempt at using the technique and could've been been caused by an unknown power outage or other numerous causes.
That doesn't mean it dosen't work, in fact, at this point in my research, I think it would work.
But why isn't there more documented grows, why isn't this common knowledge? This would clearly be the best way to grow hands down if it works.8 week strains magically are finished in 6! thats 2 more harvests a year!
Wouldn't this have its own sticky?
It's major! Time is the most valuable thing in every life. And I've just been told I can have 25% more, 25%! more return on your investment! In the world of reefer growing it is, in my opinion; earth shattering!
what am i missing here?

Wouldn't you have to flower under 6-12? or at least 9-9. The plant won't flower unless it has a long enough dark period for the correct hormones to build up and initiate flowering. Not to mention the fact that it is totally unnatural.

Edited title, for sake of comprehensibility.
Furthermore, apparently it has been said that the reefer plant does "most" of its photosynthesizing during the first 5-6 hours of lights on. Not sure how much credence I put in that, as I have grown with both morning direct sun & afternoon direct sun (ie along fences) to no major differences in result. Although, I would believe 5-6 hours of direct sun would supply a plant with "most" of it's energy cosumption for a given day.
It is also true, that manipulation of the light cycle for desired effect works, as indoor growers turn there lights on at night, yet the plant dosen't "know" its really night time outside.

apparantly my buddy was running 6 on /6 off-6 on/6off a while back, not sure why though..

Hello to every one.
This is my 1st post and strange that I would run across this question because this is what I was thinking about trying along these lines, any in put from you full time farmers would be greatly appreciated on this subject[FONT=arial, sans-serif].

I'm new to "indoor growing" I have grew a few out doors back 20 plus years ago.

So out doors I never had a plant get any more than 6 or so hours of full direct sun light and have grown some big plants. Here's what I was wondering due to cost in my medical grow at this point and time I only have 4, 4 foot 2 tube flouros for lighting so this limits what I can do.
I have 5 females that are flowering and looking good at this point and no way to buy any more lighting for awhile to come.
This is what I was thinking of trying.
I have now tryed to clone some lower limbs from the females and they all rooted on my 1st try so I'm thinking about the limited light space I have and how to get the most out of it.

So my lights cover a 2 foot by 4 foot place with the light that can go right to the plant tops and not hurt them so why not grow single clones up 6 inches to a foot tall and flower them in the SOG.
This way in the room I have I could put a clone every 6 inches, 4 per squ/foot and cover the space of 2' x 4' with 32 clones and give them 8 hours of light and rotate 3 settings of 32 plants every 8 hours in and out of the lights and never let them grow over 2 feet tall and get all bud and no stem under this setup with a light to keep a mother plant on the go with the clones under it too at 24/7 lights on.

I can't see it not being the best way to get the most out of my tiny setup, at 32 times 3 rotated at every 8 hours so they get 8 hours light and 12 to 16 hours of dark. You could let them just sit the other 4 hours in a room in indirect light like they would get in the wild in the shaded time of day if you grew them out side It's the dark that makes the bud and not the light, so if you had a tiny setup like this, would it not be the best way to get more buds pur room than just turning off the lights for 12 hours every day?

Thanks in advance to any input from you full time pros out there!

If the one garden that you have seen using this system is having re veg issues that should tell you what you need to know.

try this light schedule, 6on/18off, it sounds better .

how would this cut two weeks off of your harvest ?

The idea is to give the plant as much energy as possible while it still remains in flower
other than tropical sativas most strains will induce flower at 9.5 to 10 hours of darkness
so it would be possible to give plants 14 to 14.5 hours of light and they can still remain in flower
this could possibly result in more yield, it could also result in some plants becoming more leafy than usual

any photo period below 12 hours on is likely to reduce yield since the plant will receive less energy
overall photosynthesis will be reduced
it is important to remember that the plant requires around 10 hours of uninterrupted dark as has already been mentioned within each 24 hour period
in order to flower healthy this leaves little room to play around with the photo period

perhaps 11-13 would save you a tiny bit on electricity
from what i have read 10 on 14 off decreases yield over 12/12

if anything could improve things over 12/12 i would suggest after inducing flower , a 14 on 10 off flower period may help
reducing the hours is very unlikely to help the plants

I'd rather wait the extra two weeks.

Quit trying to trick plants with silly light schedules. It's 18/6-12/12. The only secrets commercial growers have are bad ones.
