Yeah I just read where someone grew their plants on an 18-hour day schedule basically shortening the days by 6 hours.I was not aware of any non 24hr studies by Rosenthal and the like. Plenty of members have had success with non 12/12 cycles. And with far red supplementation it seems at least feasible to shift the norm.
I am dinking with 10/10, but I need to up my cloning game to get any kind of comparable data.
I second that..18 hours of continous light, no matter how many hours of darkness, will keep them in veg. Quit trying to reinvent the wheel and stick to a 12/12 schedule. If it would actually work people would have been doing it decades ago.
who knows what they do, its all fukkery. 18 to 24 hours on and 12 hours off, those are the only two schedules needing to be exploited today.Also, when people are giving more than 12 hours of light in flower for the purpose of adding weight are they compensating the lost hours with an elongated dark period in order to keep the plant flowering or are they essentially just re-vegging with veg hours???
Pretty narrow minded advice being given. If there isn't definitive fact about whether it helps or not, why not encourage the guy to test it out? New knowledge comes from testing against old knowledge. (And even if it is definitive fact, no harm in the guy experimenting)who knows what they do, its all fukkery. 18 to 24 hours on and 12 hours off, those are the only two schedules needing to be exploited today.
on the contrary, I've listed every resource I know off hand already, read those, all lighting has been tested, we've had electricity for some time now lol. Greenhouse, light deprivation tech is old news. yes, bigger plants with longer light because of more vegetative growth. thats it. if you're into vegetative growth in flower by all means try more than 12 hours of lightPretty narrow minded advice being given.

I do wonder if a plant is given 18 hours of daylight and 12 hours of night, if it flowers and stays that way without issues, or maybe crazy like 30 on 12 off. If it doesnt hermie, does it finish flowering faster? Maybe if you use a cmh with that schedule in flower it comes out different still from the extra hours of uv? Also curious if the inverse if correct (not optimal) of say 5 hours day and 5 hours night ends up with a plant in veg. So many answers could come from his little test
I mean you listed people you said have done it but even with looking I can't find anything actually documented. It is known that 12/12 works. But where has someone tried 18/12 or more? Those are the trials OP is looking for. I've read much from the famous names you've listed, listened to them in interviews, but never actually heard anything about trying a longer day schedule than 24hrs (day+night). Mostly, they all talk about replicating nature in what to do, not changing it (which adding additional hours to a day/night schedule would be doing). I'm curious like the OP and prefer documented failures or success over "he said he did this".

Ya but he said he'd use a clone and not be wasting space already set for a plant, so I'm assuming he has the time to spend on his experiment.I learned of alternative lighting schedules form those exact sources I listed. here are some more

light deprivation is all over google in the commercial growing fields, a great place to see hundreds using alternative schedules
I think he wants to grow great weed honestly, and was swayed by the thoughts of faster bigger weed maybe cheaper power usage etc. there are lighting sources that fade light in and out during the cycle and cut usage to 50 percent if thats your kind of thing, great for vegging not so much for flowering. 12/12 has been long determined to be the best overall considering timing and cash investment and returns quality risk etc.
That's your problem, why "think" or assume what I want when I CLEARLY stated what I wanted. I already know how and have been growing GREAT weed for many, many years now. As stated, I am at the stage where I simply want to experiment and try new things just for the fun of it as well as explore newer ways to grow, if possible.I think he wants to grow great weed honestly, and was swayed by the thoughts of faster bigger weed maybe cheaper power usage etc.
18 hours of light will continuously vegetate a plant no matter how many hours of darkness you give it. your trial will fail for this alone.I HAVE A QUESTION....
If so I'd like to mess around with a single plant and see how I can manipulate it to grow bigger buds if possible.. I'm talking about doing something crazy like giving a plant 18 hours of light in its bloom phase
.. Can someone please chime in with their opinions, theories, corrections, two-cents, or anything that'll give me some clarification on the subject before I go and hermie up a good plant, lol. Thanks fellas (and gals).
Of course the whole point of growing cannabis is to get product, but who grows with the intent of getting smaller buds??????? I specifically said that I came across some info pertaining to the dark schedule being the reasoning for flowering and it made me curious to see if a custom lighting schedule would work to grow bigger buds, not that I needed or even wanted bigger buds.18 hours of light will continuously vegetate a plant no matter how many hours of darkness you give it. your trial will fail for this alone.
jorge cervantes discusses this in the grow bibles, clarke too, in their books.
why do you want to do this? you say you were not swayed by bigger harvests? but you said this
you said "bigger buds"
dude, wtf, I just quoted you
By no means should my opinion or two cents sway you either way, carry on, read those books and see for yourself. if you want cited facts ask for that instead of opinions and two cents right?
peace
Experimentation is key to crafting your own favorite grow methods and techniques, I say more power to you. That being said with any experiment you have to have a hypothesis and mine is that the ideal ratio of light and dark has already been determined at 1:1 or 12 and 12. Good luck!And just for clarification I will quote my own words and say once again that "I have been growing for a long time now and simply want to have fun experimenting at this stage, you know just for the FUN of it". Did you read that part also?????????????????????????????????????
