i will do a normal veg and then use 12-5.5-1-5.5 to see if the hour does stop flower. if light doesn't destroy florigen as you say then the hour would surely not be enough to stop flower.

well, not to beleaguer the point, but again, i don't think florigen is destroyed. it's just the final, bioactive forms of it never form. the precursors still are formed, which alone, don't cause flowering as they aren't bioactive (there are no receptors for them). same result: prevention of flowering.

in any event, keep us posted if you try 12-1. i'll do the same.

thanks for the civilized debate ;)

I understand what you mean perfectly... i'm just having difficulty reasoning it out. maturity of the planty has to play a part too. i also did a bit of reading on senescence a while ago trying to understand flowering a little more. During the dark the plant begins the first stages of senescence as soon as the lights go down and a hormone called ethylene is more greatly produced. ethylene causes premature aging.... but must also have something to do with flower. I honestly at one time considered that maybe ethylene was somehow florigen. so there's another hormone in the mix that is probably the opposite to giberillins.
I suppose I just have to do it myself and see. I'll definitely report back with my results.

I will try and update this thread in the next couple of days but my Grandmother is in the hospital and not doing well so I may be leaving out of town at any time. My nephew will have to finish things out for me. Family first

Looking very nice dude.

Do you run hydro or soil?

The only thing I'm a little worried about is when I should start flushing my plants (not for awhile obviously) but if I base it off the breeders suggested finishing times, wont I be going a little to far? I grow is soil so its important for me to properly flush. I try to go for 10-12 days before they are supposed to finish, so I'm thinking....(not a wise thing) I should start flushing between weeks 6-7 (8-9 week strains mostly) but I'm not 100% sure yet, gonna have to see how it all pans out. Are those finishing sooner than they normally would?

Beautiful plants Lilsdad. Suffering under the 12-1, lol.

they are not under 12/1. Nobody, that i remember, said they would suffer under 12/1 anyway... just that it wasn't optimum as is claimed by the article in treating yourself magazine.

I run soil and don't ever base anything on what the breeders say. If you just go by looks you should be fine, and yes they are definitely finishing faster. I started flushing last week when it looked like they had a week or two to go.

lilbsdad,
just want to let you know, from your thread and also form a friend who runs this lightning schedule you have pushed me to running it myself. I grow mostly regular fem seeds but do often have some auto's in the mix, I am truely not worried about the auto's if it affects their yield but we will see, am excited to see the response of the others and hope mine end up as good as yours. i expect the 12-1 lighting to save me a bunch of money in util bills too!

Right now, I'm currently using the 12 - 1 Modified. My cycle is going 12 On - 5.5 Off - 1.5 On - 4.5 Off. I'm trying these cuz after a month in the 12 - 1 (original) I noticed two plants in my Veg. Tent are shooting Big White Hairs all over. I will give it two more weeks, but if I don't see those hairs disappear to the old 18/6 Light Schedule I'll be back.

It is funny to see how many guru's there are all with different ideas. IMHO > When everything we know is important voor Marijuana to grow is within normal and ideal circumstances the plant adapts and will turn out fine eventually and the results will mainly differ depending on which seeds you use. I have never seen big differences between plants of the same strain when it comes down to light hours as long as the light hours are between 13 and 24 hours a day. Soil, feed, temperature, air flow, water amount, ph, pot size, parasites etc have a greater impact on the well-being of the plants and thus impact on yield and quality at harvast time. After lots of experimenting I got to this as best result. I must say fortunately I have the possibilty of using the sun, that's is always better than any kind of artificial light even when the plants are behind glass.

The first four month sunlight and artificial light combined to get to the daily light hours.
- Januari 24 hrs
- Febuari 22 hrs
- March 20 hrs
- April 18 hrs
- May the plants move outside out of the pot into the soil of garden and enjoy 13/14 hrs of sunlight until the end of September
- October when 12 hrs a day they start flowering
- Decembre ready when there is only 10 hrs of sun left.

This is how I got the biggest tree after 11 month time, you want to grow quicker you cut out the days in comparison.
Have fun!

You are right ! lo But you get my point ! For some reason I'm not liking the 12 - 1, I got 5 Plants in the tent and two of them are showing Pistils like crazy, but the funny part is just two plants out 5. Coincidence or maybe is the strain ?

You are absolutely right, however we are talking here about that type of schedule help the indoor farmers with their electric bill, nothing more. Good to know you like the Power of the Sun, me however Love the Indoor cuz i can control everything from A to Z.

Plus you can beat the fact indoors you are constantly busy with Perpetual harvest in Outdoor not so much.

you are contradicting yourself. first you say cannabis is an outside plant and is best to mimic the natural light hours so you wont stress the plant, then you go and say try this unusual light schedule that is nowhere near natural light schedule (but somehow theres no stress). i have never experienced 12hours of light and 5.5 hours of darkness in real life nor 1 hour of light and 5.5 hours of darkness. ive always been open minded but there is no way i can try this as i have a job and a life and in order for me to try this i would have to have alot of time just to change the light schedule everyday
edit: also if your trying to mimic nature then do it right, theres 24hours in a day and that light schedule you posted is no where near natural

I'm with you how is 1 hour on natural? I like the flowering schedule though.


Edit**

I got this from somewhere earlier today.

Why would you have to change the light schedule every day?
Veg: ON 5am - OFF 5pm - ON 10:30pm - OFF 11:30pm -
Bloom you would change your light schedule 4x in 8 weeks by dropping 30 minutes each change starting at 11 hours of light.

The veg may not seem much to natural but the bloom schedule is closer to real time.... it makes perfect sense.

I have had a friend run this schedule for a couple years, and does very well with it... hence me changing my light schedule.

I've been worrying about my vegging plants a little, pistils show up, and go away..... show up and go away..... these were ran in 20/4 for the beginning of their lives and then I switched them over 18/6 right around when they matured, then to the 12-1 a few weeks before I flipped my big tent to 11/13. I'm at the point now that I need to get setup for my next grow and I am going back and forth on the idea of popping new beans and starting from scratch rather than setting up clones, or atleast going 50/50 new beans and clones from the genetics I have already... It sucks thinking about offing the genetics I have going, a nice pheno of jillybean, 3 sour d's, original amnesia, confidential cheese, 2 of the same querkle pheno, 4 of "the void", burmese kush, and a couple other I cant think of at the moment....Sucks....

maybe I'll just pop a couple just for backup.....any thoughts?

I'll post some pics tonight, my flowering tent is coming along nicely....

Chances are, changing your lighting schedule on them has caused some of the issues you are seeing. Think about it, you went from 20/4 to 18/6 then to 12-1... though the 12-1 is to trick them a little with the 1 hour on, you have lowered the daylight, almost to bloom schedule from a start of 20/5 - 18/6 etc... The plants should be fine though, plants are resiliant.
