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

[wheezer]

Take a deeeep breath UB.....

Let's be clear, I don't give a rats ass what you do. My argument is with the guy that wrote this garbage. The typical noob will fall for every gimmick and snake oil that comes along....that's just what they do.

Having said that, if you can poke the author, get him over here. I feel feisty..... feel like it's time to open up a can of whup-ass on that boy. (botanically speaking of course)

all the knowledge you have isnt first hand tho is it, its knowledge you are qouting from some book or article or other.
it says typhoo on the side of the bus but you cant get a cup.

 

[tellno1]

wasnt ment for you lowrider2000 .. you posts do make a lot more sence then the others i was referring that too .. that said .. dont you think that since the plant only reaches full production the first 50-60% of the day using the dim schedule will have nearly the same effect as the 18 hr?

 

[lowrider2000]

it seems to chaotic for me that on off on off stuff.......................

 

[azman]

for a digi timer its adding the second prog foir veg coming on o5.5 hours in and going off 1 hour after,
for flower its knocking 30 mins off the off time once every 2 weeks.

i haven cut and pasted shit but fuck it this is for you

And it's wrong, again.

The Theory
The theory behind the 18 hour Day/Night cycle is that during a normal 24 hour light cycle plants will usually achieve high growth rates peaking at 100% capacity during the first 50 - 60% of the day. The growth rates will then diminish rapidly and the last 20 - 30% of the day achieves minimal growth. So by reducing the length of the day we are triggering an increased growth mode where the growth rates are at their peak for the majority of the day. This effectively achieves a very fast growth cycle with full yield potential.

Not accurate. A plant is capable of receiving only a certain amount of photos during the day, that is called a light saturation point. Any more photons over that amount is a hindrance and/or detrimental mainly due to a requirement for more C02, but I digress. A master gardener will find the saturation point for his particular crop and tweek all cultural factors to the max.

Having said that, it's true, a plant's photosynthetic efficiency is best while receiving morning sun, but then again that may be relative to what's received the entire day factoring in heat, etc.

NOTE: .....The recommended lighting is 600W per square meter.

False absolutes here. (Kinda kin to "true lies".) Depends on the other factors.

The Cycles
Vegetative Cycle - Lights ON 14 hours, Lights OFF 4 hours

What's the plant's light sat. pt.?

Flowering Cycle - Lights ON 6 hours, Lights OFF 12 hours

Highly limited food production due to limited photosynthesis compounded by excessive respiration rates which deplete carbos manufactured during the day. A double whammy against tissue production and maintenance.....just plain stupid.

The Benefits.....

Feels good.

i found the thing about digital timers is that you have to make sure the contact ratings will work for the lights .. some of them are very low amperage

 

[lowrider2000]

i think the vegg stuff is crazy you can almost give plant any schedule in vegg and they will grow......as far the receding light in flower it wouldn't harm them... i like the 12-6 on because if you think about it over a 24 hour period your giving the plant the same light you would in a 12 on 12 off schedule

 

[azman]

yes, i had a segment break on me ond vowed never to cheap out on timers again the one i run now is a contactor and timer running at 26 amps.
is enough to power 6x600's apparently.

props on the big words but answer my last post

 

[tellno1]

i see your point there about it being the same as 12/12 .. you use this timeing correct? for veg and flower?

 

[lowrider2000]

no i want to but no the most i have been doing is turning one of my two hps lights off after the first 6 hours of light...have done if for two harvest with a strain im familiar with and have not notice any loss in average harvest

i built a little relay box with higher contacts .. so my little digital contols it not the lights .. dont have to worry about it flaking out on me

 

[lowrider2000]

vegg i just put my clones in constant light for 2-3 weeks i dont really stress vegg tho

 

[tellno1]

i found with using the 12-1 my plants didnt stretch near as much when i put them in flower .. for me that was a positive

nice lookin plants lol looks really thick in there ..

happy growin

 

[reverof]

I will leave my comment at this, I know a guy who grows commercially, has grow for a few years now, quite a large setup, a little over a year ago he changed to 12-1 for vegging and flowers at 11-13. From his experience his yields were higher with the 12-1 in veg, not 30% but higher than previous, he stays on it steady and cut his utils down huge, he has roughly 20 1000w lights.

I'm happy to see that someone is trying out this 12-1 lighting method. I have read about this in plant biology reports, but I have been nervous to try it out myself in fear of ruining the plants or hermies developing. However, kudos for giving this a try and posting your results. In actuality it is the red light responsible for tricking the plant's into thinking that they only have a short night...and you could achieve the same results just running a red light for 15 seconds half way thru the dark period.....

Great post and forget all the haters and shiz talkers....without innovations and ideas being tried....we still would be cutting with stones and hunting with bow's and arrows.... Great job!!

 

[lowrider2000]

and its blue light that you can put in your box during the dark cycle and your plant will keep flowering also growing
