14/10 Light Cycle

[High_Haze]

I am starting some seeds indoors to get a head start on the outdoor season. I tried to post this in the outdoor thread but apparently not too many people have indoor experience there.

Jorge Cervantes said that you can start growing your plants indoors while following the outdoor natural photoperiod. For example, if there are 14 hours of light per day, give your plants 14 hours of light per day as well.

Since I will be transplanting in May, the natural light cycle here in Colorado is 14/10. I see conflicting information from people on whether or not 14/10 will induce flowering. But if the seeds are raised in 14/10 from the time they sprout I don't think that they will flower.

Anyone here have experience with this schedule?

I've started plants and grew them for 2 months under 24/0 and then put them outside and they continue to veg just fine. So yeah 14 is fine as is 16 18 or whatever else above that

Thanks for the feedback Covert.

Unfortunately that is not always the case. Last year my seeds were seized and I had to get some clones last minute. One of the batches of clones I got started to flower a couple weeks after I put them outside. That was the first year that had happened to me. A lot of people get lucky but its not that cut and dry.

I am interested to see if anyone has had success with a 14/10 veg cycle inside then moved outside at about 4 ft tall.

You would have to plant when the light is increasing in time not decreasing in time. Which is around May 15th.

My hope is that a 4ft head start would allow the plant to grow into a monster by late August when flowering begins. But i've never seen anyone try it. Nor have I been able to try it myself.

Flowering begins in early August.

Yea that is the goal. I am going to Veg for a couple months and then move out around May 15th to May 25th which will be perfect timing when the light cycle is still increasing. Hopefully the 14/10 will avoid the early flowering.

No s#$%!! LOL

ttystikk,

Ill give you a quick cannabis 101 lesson..

Flowering is induced anytime the cannabis plant begins to sense a reduction in the amount of daylight hours. There are lots of people who have accidental early flowering outdoors by moving a plant at 18/6 or 24/0 outdoors where the hour are closer to 14/10. The plant senses a reduction in the hours of light and flowering is triggered. Doesn't matter if it is August or not. But yes for most people flowering starting in August is the goal, hence the reason for this discussion..

I am interested to see how it works out for you High_Haze!

 

[High_Haze]

I thought that the plant needed to receive just about 12 hours of darkness to start flowering outdoors. But maybe not?...

What your saying doesn't make since because if a plant flowered simply by reducing the number of daylight hours; then flowering would start after june 21....

That is roughly when it begins there are a few more factors like the genetics. And yes usually you want to avoid the plant receiving 10 hours or more of darkness to avoid flowering.. however, many people have early flowering by moving an 18/6 or 24/0 plant outdoors where the hours are significantly less. Some people in warmer climates take advantage of this by vegging indoors and moving outdoors when they are ready to flower. Remember flowering is more prolonged outdoors too.

"Indica dominated genes have to become sexually mature before they flower. That varies, but it is like 4-6 weeks. After that when the lighting starts to decrease in the day they will flower.

If you take a clone outside (already sexually mature) it will start to flower as soon as the light photo period reaches the level that makes that strain flower (14-12 hours of light per day)"

The hours here in Colorado never get above 15, so a drastic change, like 24/0 or 18/6 to 14 or 13/10 is enought to induce flowering for some strains.

Thanks boss I might start up a thread this grow. I have chocolope, holy grail kush, afghan kush, kali mist, ghost train haze og, and lemon og

 

[mean.green]

Awesome, I am also growing Ghost Train Haze!! Although mine is a hybrid (ghost train haze x cheese) and (Ghost train haze x Chemdawg) If you start a journal, I would definitely follow.

 

[High_Haze]

That sounds like some great hybrids! I grew the ghost train haze #9 a couple years ago so I wanted to try the OG this round. I almost got the moonshine cut but I decided to save that for another day. I followed your journal so ill check in on you. Happy growing brother!

Again that's exactly what I do except under 24 hours. I don't want to be one of these people who acts like I know everything but for me it has always been quite cut and dry. And I have never had one try to flower early.

Awesome Covert222! Are you using an auto flowering strain?

I hear you covert..

I have been growing for 5 years I don't know how long you have but last year was the first time that this happened to me.

And if you do a quick search it happens to people quite often. You have gotten lucky so far just like I did, but this is a very real concern and after going through it last year I wish to understand it better in an effort to avoid repeating the problem.

I would love to grow under 24/0 or 18/6 and get that extra veg time in but it's not worth the chance for me. And the information regarding 14/10 is debated among people that is why I was asking for some feedback from people who might have tried.

No but I have grown different strains every year and it works

Hey brother I'm not doubting anybody who says it happened to them for 100 percent . I believe you of course I'm just speaking from my experience and that's how it was for me. Also I don't harden off either and it's caused me no grief. I did have one plant die last year and I suppose that could be why

I'll give you a quick lesson. Cannabis most certainly does not begin to flower when it senses a reduction in light. Cannabis flowers when pjytochrome red turns to phytochrome far red and that happens based on the amount of darkness

LOL! What the hell are you smoking I want some of that. Reduction in the amount of light is the same thing as the analyzing the amount of darkness.. You just said exactly what I said but you tried to throw in some scientific jumbo that the average user won't understand.

The trigger for cannabis to switch to flowering is strictly in the photoperiod. The color or spectra of your lights or amount of radiance has no effect on this transition whatsoever.

When the sun goes down or the lights go out, the darkness gradually switches the PFR to PR. Because of this, PR levels gradually increase and the PFR gradually decrease during the dark period. The presence of PR is a neutral condition to the plants and essentially tells them nothing. When the light returns, or if a small amount of far red light interrupts the dark period, the PRimmediately switches back to PFR. If the plant is without light long enough, the PFR will decrease past a tipping point. This decreased level of PFR signals the plants that Fall is approaching; and the plant begins flowering.

You don't harden your plants off and you clearly don't understand the flowering process of cannabis. Please take your "knowledge" to another thread.

Hey dip shit by your rational if I went from 24/0 to 23/1 my plants would flower. Now you're trying to cover it up by saying that were saying the same thing which is why you're a dip shit
