Anyone had Expeirence with 14/12 Light Hours?

basicaly didnt remember to turn the light off (was 2 hours late) and read in a post the other day that plants only count the 12 hours of dark, therefore meaning the light hours have no detrimental value, is this true? i was thinking of turning the light on 2 hours late and keeping it that way? im off to get a timer 2morrow anyway so this wont be a problem in the future, Im 3-4 weeks in flowering so i have no idea how this will affect them, any input would be great, thankyou

once or twice messing up the light schedule won't harm a plant, it's more about light leaks and a week+ of wrong light times, generally speaking it seems 12hrs is just the magic number of light to dark time used to flower, its possible to flower in 15hrs of light sometimes, it just needs less and less to trigger this effect.

During the 12hours of darkness, the plant produces the substunces that needs for flowering.
If you keep a constant 14/12 it meens that you loose 12hrs of darkness every 6days....
This means that by the end of the month you will have lost 60 hrs of valuable darkness.. (correct me somebody please if wrong)

I had the same idea as you but i just figure those out and i dont think it will work finally. I like your way of thinking man. GO EXPERIMENTING!! Immitation sucks

peace

Well you say by the end of the month you will have lost 60 hrs of valuable darkness last time i checked the plants only get bigger in the light so i would say you have gained 60 hrs of valuable growth. I have some bud going now on a strict 13/11 shedule and the are doing great . i'm probably only a couple of weeks out to harvest. When i can get a timer that can handle 14/12 i am definitively going to try it it's just funny that there is no info on someone trying this or some journals with 14/12 light shedules .

you want to be carefull increasing the amount of light a plant gets during flower as you may cause it to revert back to vegatative stage and thus stop all bud growth. experiment with what you want, i enjoy a good experiment as well just be carefull dont want to do something you regret this close to smoke time :)

anything ever come of this? i know its a super old thread, but i was just wondering the same thing the other day. hence why i dug this old thing up.

does anyone out there have experience using a 14/12 or even 13/12 light cycle? no 13/11's i mean using days more than 24hrs in length.

12/12 is just a standard used to ensure all strains will flower regardless of their natural origin
only around 9.5 hours of darkness is required to trigger flowering and reach the point of critical darkness
i have flowered on 11, 12, 13 , 14 hours on 11 hours i noticed less yield, 12-14 from what i can tell there is very little difference if any that i could notice
some very long flowering 16-20weeks sativas will not enter flower on 12/12 for months and can be put on a 10/14 hour photo period to induce them quicker
if anything giving them more should increase yield due to an overall increase in photosynthesis, upto a point where they will start to try and re-veg or grow more leafy
as i said i noticed very little difference, overall i think it was a waste of the extra electricity ill stick with 12/12

peace
