It’s a simple question… Only for indoors
Why do we make the light cycles depend on 24 hours?
Is it the readily available timers?
Or the the plant herself?
would be interesting if someone tried to grow 48h a day. 8h dark 40h light😎??? Then switch her to 12/36
Would she still switch at 12h or would she switch at 24h???
Would she adapt over several generations?
Light such an interesting ting about indoor…
Last I checked there was only 24 hours in a day, so this would only work if the world was flat 
On another note… whatever you’re smoking, I really want some of that! 
I would venture to guess that if the plant started out on a consistent 48 hr cycle it would try to flower just almost right off due to the genetic need to flip on regular 24 hr schedule.
I do think you could manipulate it with certain strains that are extremely forgiving of stress (light wise).
I don’t know much about growing though so what do I know anyway? Lol
Wow… you got it good! We only have 24 hours in a day - with only one sunrise…
Always wanted to live on a planet with 2 suns… 
Yeah Matty! We have such great ideas in the circle. We should record some and listen to them later!

This would not work.
Short-day cannabis (as opposed to autoflowering cannabis) is scotoperiod sensitive. The day period and night period produce different hormones, and the hormone ratio blocks or initiates flowering.
12/36 would stress the plants out. And there’s no benefit to doing it, unless maybe you want to see if they’ll turn hermaphrodite due to abuse.
If you want to run your lights all the time, use autoflowering plants.
I was thinking about this a couple months back and posted about it. People here not fond of the idea . I almost want to play around with it but have other bad ideas with more merit to pursue first lol.
My thought was how far can we extend the light hours, while still giving the same 12 dark uninterrupted hours. Would they tolerate 14-12, 16-12, etc.? I’m not so sure it would definitely fail at 13-12. Or 14-12…plant would certainly bug out at some point but I also wonder how far you could push them. Why? I can’t justify it but one can ponder.
Move to another planet & call & tell us how its going
| Planet | Length of Day |
|---|---|
| Mercury | 58.6 Earth days |
| Venus | 243 Earth days |
| Earth | 23 hours, 56 minutes |
| Mars | 24 hours, 37 minutes |
| Jupiter | 9 hours, 55 minutes |
| Saturn | 10 hours, 33 minutes |
| Uranus | 17 hours, 14 minutes |
| Neptune | 15 hours, 57 minutes |
| Pluto | 6.4 Earth days |
Take your pick, bus leaves in an hour, an can I try some of your’s please?
Found this but it will take a while
As a point of reference, this rate of slowing means that it will take 25,000 years to add a half a second to the Earth’s day. A whole second will take 50,000 years.
how many hours a day?
It’s that new Chinese math there teaching.
Lol having a hard time to free your minds… Do you think thats air you’re breathing?..
A day goes from sunrise till sunrise, how long that is, is totally up to me… At least in indoor setting.
Has it been done? From the lack of answers It seems not…
The issue here is your plant.
She can only absorb so much light before she becomes exhausted, she can only draw so much co2 until she can’t absorb anymore. Then it becomes toxic
Without darkness she can’t off gas and she can’t finish the photosynthesis process she’s worked so hard in the daytime to accomplish.
Most people do like extending a 4 month process further, I say make a journal for it and tag me … I love watching weird crap
This is almost a question for NASA…
They probably asked them self how we going to grow on a planet with different cycles, how quickly would a plant adapt… To let’s say a 48h day… Or are we earth bound and our crop would never adapt to a new day night cycle. At least not in a timely manner so colonies could farm. Other planets…
Playing around with light timing is actually going the other direction. Using multiple shorter periods appears to have some merit. I know at my age a little nap works wonders.
Must be a generational thing with wanting to make things take longer then they need to.
I’ve always been raised to get things done, not extend the time it takes …
NASA already knew that there’s a saturation level for plants and light and knew that they would only need so many hours given to be able to produce their crops.
It’s not the twilight zone it’s basic biology
Can you link to an explanation of that dark period photorespiration process? That explanation conflicts with the description of CO2 utilization during photosynthesis in C3 plants (How Plants Work by Linda Chalker-Scott).
A plant can only utilize a certain amount of photons per second. There are 43,200 seconds per day, so there is a maximum amount of light a plant can use per 24 hour period, but that metric is misleading. If we exceed the amount of light a plant can handle per second, we hinder the photosynthetic processes.
I can imagine someone overdoing CO2 supplementation by omitting a solenoid regulator, but I’d imagine the CO2 would harm the root oxygen uptake before it harmed the RuBisCO process.
I answered your question…
It is obvious to me that seeds will not thrive in any environment that doesn’t mimik it’s origin.
I must have reading difficulties, because I only read an explanation of why no one would do it…
If i get nasa to fund me I’ll do it lol
