co2 at 1800 ppm doesn't happen in nature either. Give it a shot if it doesn't work or plants start going retarded you can always change the schedule

yea i agree with wut he said

well i dont do it with co2 or keep up with a ppm just the ph and and the air im my grow room
o btw if u do use that type of light schedule and then switch it u cause a lot of stress onto the plant
ya but 12 on 16 off is pointless people do do things like 8/12 to speed up flowering by a couple of days or 16/12 to extend it and improve the yield slightly but cannabis is short-day flowering and the chemical signals which induce flowering are produced during the night cycle so you want to have the night 12 hrs and the day length variable.
I'm not so sure changing the light cycle in that way would stress em all that much if you keep the length of night time constant.

if the plants go retarded or hermie the light schedule is the stress changing it back to 12/12 would relieve that stress

yes but it take 7 day to relive it of its stress and if it goes hermi then u cant unherm it

It's possible. Using Earth measurements, I think planet Ito experiences 21:29 hrs of sunlight and 12:07 hrs of nocturne totaling 33:36 hours a day, 5 days per week. You're going to need bring lots of nutes/fertilizers and expect a massive harvest for just enough for your return trip back to planaet Earth.

This would stress out the plants I think. Nature doesn't provide different lightings everyday so why should you.

Screw the naysayers man...nature doesn't provide marijuana with a 24 hour "on" light schedule for veg either, but lots of people still do it. I never saw marijuana growing aeroponically in nature either. Come to think of it, I never knew nature to intentionally provide plants with the perfect ph or amount of nutrients either. I could honestly go on all day.
My point is, if people didn't try anything but what others have already done, we wouldn't be seeing the awesome results that we see today. It may work well, it may not work worth a shit but hey......you tried. Experimentation is the only way to achieve a better result.
I'm growing bored with people that are SO SURE that their way is the best way.

Hilarious...... There is never a "right" and a "wrong" way to do things. Guess it depends on your definition of right and wrong. That seems to vary alot around here

nice quote... shit lot of people tell me something wont work but i try it anyway ... cuz nothing is perfected the first time... even if it didnt work for one person that doesnt mean that the next person wont think of something slightly different..

In my opinion I think 12 on 16 off would be better then the opposite because wouldn't the plant maybe try to reveg with 16 hours of light a day? I have seen veg times say to use in between 16-24 hours of light a day. This is more of a question then an answer

this guy presents the perfect point here... every piece of literature i've read states that cannabis needs at least 12 hrs of darkness per day to initiate flowering, leaving a maximum of 12hrs for light per day;... but that is assuming that EVERYTHING operates on a 24hr cycle..... which it probably does, considering the sun has a fairly consistent cycle at about 23.5 hrs per day (from sunrise/sunset times).....
i think an experiment between these two extreme light cycles, (12/16 $ 16/12) would be a great idea..... we've gotten into the debate here before (back when the "advanced cultivation" was fun and full of ideas
) about when the bud actually grows.... some say the bud grows during the light cycle/photosynthesis, while others argued that the plant actually stores the energy from the day somehow and the bud itself grows at night.... both sides presented valid arguments with backup...... this experiment ^^, assuming the plant would still bud correctly under both light cycles, would IMO prove at least which cycle is more crucial to yield.....sorry for the rant, I'm catching a good one

I've wondered about it myself. I know research must have been done on the effects on agriculture using different day lengths. NASA does alot of ag research and this would be something they surely have looked at by now. I am actually more curious as to the effects on yields if one were to use a decreasing light cycle as seen in nature during flowering. If a particular strain begins flowering at 13/11 would using a sunrise/sunset schedule that corresponded to nature effect yield?
