Reply With QuoteActually I was talking about using an 18 hour day divided into 14 hours of light and 4 hours of dark. Then for flowering -- 6 hours of light and 12 hours of dark. I was wondering if I am the only one in the world doing this.
For alaska, yes ive seen them in person and on discover channel and nat geo and science channel. Look something up geez.
Heres a study from oxford university with various species of plants. Where in 24/0 one photosynthesis respirating increased dramatically while the others stayed at a constant.

Either way. More light , 6 hours more per day. So obviously it will grow faster and node spacing shorter. When lights go out. They stretch a little trying to reach light thats not there.

I've heard of people doing strange shit like that, so no, I don't think you're the only one, but, idk what it does, at all.Originally Posted by Glider
What would you be doing that? Would you save on electricity (I can't do the math, lol, shit starts getting weird).
Theres been other threads where people have done that. It does work. But since there are more dark periods. The plants finish much faster and much smaller yield. For example. If you just ran 11/13 instead of 12/12. It would finish a week earlier. So if you create more dark periods, especially more than one dark period per day. They will finish that much faster and smaller. I dont want to do the math to figure out precisely. For veg it would just grow slower. More continuous light in veg. The faster it grows. There are acceptions where some strains might react differently. I never seen that happen. In veg if they get 8 hours or mor of darkness, they will flower.

If u look in my threads, I messed around with light cycles. I done 7/12. Setting the timer was a nightmare but I got great results. Never finished quicker but ended up with plenty of bud
Hey super, what was the yield difference vs 12/12? Actually what did you do with the extra 5 hours? Did you mean 7/17?

Im doing 16/8 right now for my bubba kush. Time isnt a factor as its perpetual. I must say its slower but saves on high power consumption.
Thanks Super. It is a bitch setting the timer. I am doing 6 light/12 dark down. We'll see what happens. So far I am very happy with the size of the plants and their form
I took a plant biology in college and yes, plants do need darkness to grow.
The photosynthesis process itself, there is a reaction known as 'dark reaction' pathway or lately known as 'carbon reaction' pathway where the free energy of ATP and reducing power of NADPH, are used to fix and reduce CO2 to form carbohydrate. This is very important process to release Oxygen into the air. This happened in the dark or at night.
