6/12 bud

ok first where can i go that gets 18 hrs of sun and then suddenly one day switches to 12 hrs of sun.???????????????? nowhere. so all indoor growers are manipulating the light cycles of plants to begin with. i think what you are doing is good i just wish you would post pics and update this thread with how the plants are doing. since none of us have said weve tried this its all on you ... you will need to do two identical grows at the same time one with a traditional 12/12 and the other with your 6/12 to see the difference in yield , growth rate, and quality.

i think im moving soon within the next 2 months ill be tryin this but until then lets see somone else do it!

this is not my idea just something thats been thrown around by some people on here then i met some people at harvest fest in maine and we all talked about this their. so it not new. i am having hip replacment next week and i cant find the timmer i need so i had to go back to 12/12 untill i get better.

nobody will ever do this.

exactly what im saying if its not broke dont fix it!

This is a stoner website...

ok where to start...

nowhere on earth provides only 6-8 hours of light without freezing, around 30 lat. the shortest day is 10 hours and anything farther north occasionally has an early frost...

I dont believe the plant would adjust to an 18 hour day, no matter what...

I know that the light cycle in nature doesnt switch from 18/6 to 12/12 naturally, but its still a 24 hour cycle.

just look around at all the experiments done with plants in relation to their circadian rythyms and you'll realize this will never work anywhere near as well as a 24ish hour cycle

also I did read the entire topic, but was amazed no one brought up the plants internal clock...wtf?

i actualy am starting to think this might work. DJ short or wut ever has strains that are ment for 24/0 lighting so why cant you change it to a 18 hour day? and even if the plants clock is set to 24 hours if you keep doin this theoreticly wont each generation of the strain become more acustom to the 18 hour day?

ya...go for it

prove me wrong

but heres some info for ya

But we're aiming for the same thing they're exploring in that link.. The means by which the clock functions, and from that, how to compensatively adapt it.. Remember, the chemical mechanisms responsible often calibrate themselves to equilibriums we can shift..
I did a crop once on 21:36/12 (That makes 5 full plant days on a 7 day timer).. Probably wasn't worth it, but I did notice that my plants quickly learned when to expect lights out.. Just over 21h into a light cycle the leaves would relax, and just before lights on they'd perk back up again..

Wouldn't this be a pain if you wanna use a timer? I apologize if someone brought this up already.

12pm - 6pm light
6pm - 6am dark
6am - 12pm light
12pm - 12am dark
12am - 6am light
6am - 6pm dark
6pm - 12am light
12am-12pm dark
12am - 6am light
etcetera.

Fuck that. I understand how it's supposed to cut off the less productive end period of the light hours, but I'm not making a complicated system to turn my lights on and off. I also don't know if this wouldn't affect plants negatively or not. I'm pretty sure the plants would adapt to the new hours of light/dark, but this conflicts with a personal account from a friend of mine that swears by a 16/8 flowering day.

you can't discount evolution.

the timer thing is really the pain in the ass, as most are for 24 hour day, which means unless someone makes an 18 hour day timer, you just have to get an on/off cycle timer.

that one is 275 dollars in Australia


I think it'd be fascinating to watch a test grow with this 'theory' and figure out the whole grams per watt thing.

Humans force plants and animals to evolve constantly, quicker harvests are SO enticing! I really like the saving energy part though, as it's not cheap to run HPS lighting.

evolution happens over MILLIONS of years.

I was going to mention that the length of a day used to be as short as 6hrs, but that changes REALLY slowly..

Plants use a chemical system to tell time. The chemical is degrades during the day and it builds back up at night (maybe the other way around). By monitoring the levels of the chemical in accordance with other factors the plant feels, the plant can tell if its day or not, and how far into the day or night it is.

Even though, just like us, it would be a shock to start a new sleeping schedule the plant would eventually used to it. However, I do think that just like us, plants of different varieties (and even individuals) can have different needs for sleep. Humans need around 8 hours of sleep, and some people use much more or less based on their own needs. Although in this case with plants we're talking about hours of light and not dark hours, I think the same may apply. It may not apply. I'm not sure. Is 6 hours of light twice a day the same or better than one burst of 12 hrs? Some people say no. I tried sleeping for two groups of 4 hrs instead of 8 at once and it worked alright...

Let's say the plant gets used to the timing, I still don't want to spend the money on the timer or sleep weird times.

Granted humans can function on an altered sleep schedule, but its been proven that best physical and mental performance occurs on a stable early to bed, early to rise schedule..

I'm not saying that i'd advise it but there are those who would disagree - look up polyphasic sleep - there is a whole range of routines (uberman is one) I believe it is a bitch to adjust to, but some people (nutters mostly) swear by it. NASA has also experimented with this and i believe that it has been in use on the international space station..

All that said i think 12/12 suits plants best and sometimes myself!! Yawn!

well apparently marijuana at the LEAST understands what 12 hours of dark are. think about that for a while.

hey fdd you dont think this will work even if you keep the 12 hours of dark?? i think you can switch the cycle over a few generations...

no it won't wok. you could have grown a normal crop in the time we've all rattled on about this.

is this a race?
