12-1 lighting schedule, has anyone actually tried this?

Off the should I or should I not use the 12-1, let me ask this....is anyone cloning with the veg. sch.? (wait a minute....) I am getting ready to take some cuts and I'm going back and forth. I know theres only one way to find out but just a little curious as to what others are doing.. I have a tent full of over grown nastiness that I need to shrink down and in the process setup for the next grow (which I've been doing for a good 2 weeks now)

Also, Octobers E-bill came, into the $470's down from $650+. Not exactly 75% but a couple hundred dollars is exactly that.

I do have to agree with UB and the others about newbs seeing this and jumping in, this isnt the only site I look around on and every other site has a new 12/1 thread because of the article in skunk. however...theres nothing you can do about it. They are going to F their crops up one way or another (I may even) so let them/me do it, and try not to make them feel too bad about it. If your advice isnt heeded, no need to start a pissing match over it.

Some pics from last night, day 29.

well its been a long day for me,
all my girls are now chopped and on the rack drying.
yield looks good tbh better than last time,
thank god for the spin-pro is all i can say lol.
my first time growing big bang 2 and christ are those buds dense and really heavy too.
ill update with pics and yield once dried.
also whitey these were clones started on the 12-1 from the get go.

Really nice. How far along are you?

I do not clone in 12-1. When I started trying 12-1 I had a Blue Cheese I was reveging. Which stayed dormant for 5 weeks. As soon as I moved it with my clones into 24-0 it started growing. So this being my second round. clones went from 10-14 days at 24-0. I then when to 18-6 until the where 3 weeks from cloning start and switched to 12-1. I'm now about 1 week at 12-1 and they are doing beautiful.

That is really nice azman. I may have to try 12-1 from the start.

Just so you know every time I see you name I think of the seinfeld Assman episode.

Now that UB has weighed in on this i wont be running 12-1 anymore. I was waiting for him to show up and give the facts. I heard about this on a radio show from a guy who said it was the "industry standard" for comercial grow houses....i thought he meant professional horticulturists and not pot growers, so i went with it after looking up a few grows using it.
Now, my plants looked healthy enough but what did i gain and what did i loose????

You tell us....did you gain or lose anything? if so what?

Thats my question also. If your doing it yourself you can see what you are getting with it or not.

Sorry I didnt give more detail about what i meant.
I have never run this strain before so i cant tell if they grew slower then they would have under a different schedule. I did save a little on electricity but Im now guessing that it took longer to veg.
My point is that i will always go with botany over MJ myth, and Uncle Ben brings the botany.
Im not dissing on anyone because i tried it myself...so please take no offense.

I love it when people jump when certain people say something.... you were testing this method for your own trials, but you were testing a never before strain, you stop your test in the middle and never get to see a true result.

Again i will state this: I have had a friend running this schedule 12-1 for veg and 11-13 for flower for over a year now, in a LARGE grow, his final numbers have consistently been higher yields (though not much) than 18/6 and saves a ton on util bills. We are talking 10 1000w lights in veg and 10 in flower.

Hell even on lemon haze auto's that I am running in my veg room have I seen huge difference in the 12-1 in the growth and now bud sites, these were plants i was expecting it to hinder. I grew this same strain before and average plant height was about 27 inches at harvest, my average right now is 31 inches and minimal to no stretching, honestly felt I had more top stretching in 18/6 on my auto's.

I don't get what people constantly complain about the 1 hour in between the 5.5's as its only purpose is to keep them in veg, sure they get alittle charge out of the hour but not much. Though it is not exact to nature, the 12 hours a day of light is much closer than 18/6 or 20/4.

In veg there is much more stress by many growers than a little light for an hour, and if 1 hour of light does major stress to a plant, then what do you think 20 hours of light does to the plant?

I respect Uncle ben's opinions, but as far as seen differences and actual trials done, and watching major grows using this, i cannot put this method down in any way shape or form. I am just sad I didnt pick up using this schedule well before now.

Maybe this has been explained and I missed it. But why is the 1 hour there? Why not just go 13/11 from the start? Its still 13 hours of light 11 hours of dark. Isnt that enough to keep it from flowering and doesnt double the start up? Then if you go there, well havent people been studying static light schedules for a long time and the opinion has been 18/6 get the best results?

If the only reason the 1 hour in the middle is there to keep it in flowering, just doesnt make sense not to just add that hour on to the original.

No,I didnt stop half way through ...i ran it all the way through and they are wonderful plants. I never intended to use the flower schedule, only the veg schedule.
As for jumping when certain people speak up...hmmmm, well Uncle Ben has changed everything about the way i grow and all for the better, I cant argue with the results, so yes when Uncle Ben speaks about MJ growing I listen.
I have looked for a scientific article about this method but havent found anything except MJ growers speculating...not sayng it doesnt exsist but i cant find one article that tells us in uncertain terms why it works.

Again...Im not dissing you or anyone else.

Ok I am going to ask again since its been covered up.

What is the difference in a 12/1 and a 13/11? you still get 13 hours of light to prevent flowering, 11 hours of dark and dont have double startups?

To be honest some strains may start to flower under 11 hours of continual darkness.

So you are stating that you ran the entire veg cycle at 12-1 and the plants are beautiful.... But because Uncle Ben says its a joke and you couldnt find scientific reference to it you are stopping....

Hmm you prove something works excellent, but you would rather pay higher electric bills. i am way confused.

Some strains will flower with 13 hours on 11 hours off. As I understanding placing hour of light in the middle of darkness interrupts the chemical response in the plant which begins flowering.

Not one of those sites are credible, scientific. (Where is Mel Frank and the U. of Miss. when you need them, hah!) If you're hard up for money, perhaps you could find a a window or grow outdoors......or, just get a job so you can pay for the electricity. Anyway you factor this all in, you're buying light. That's the issue, not electricity expenditures. The plant requires so many photons per light cycle to get to where you want it to go.

Folks, as I said before, you proponents who are cherry picking stoner sites to support your position are missing all of the science based factors I pointed out - phytochrome production/processes and a plant's light saturation point. Again, this biz is all about gimmicks. If it aint a snake oil, it's some off the wall light schedule. I've about seen it all.

thing is tho uncle ben, the veg side worked better for me than any other lighting schedule,
as for flowering time i have cut my girls and will know better once they have dried b ut on first looks, it was a good harvest.
kinda hard to dismiss as snakeoil when it has been done and worked for me
