Lol, you would not know what to do after smoking his stuff.

YOU don't believe. But you've never tried, so...
Dude has a thread called "how a finish plant looks like" or smt like that. LOL.
I learned from that thread... after 2 y of growing.

I'm running a veg cycle of 12 on 3 off 6 on and 3 off, out of necessity and everything seems to be doing good.
It's a bit early for me to form an opinion, yet. I'll give it a few more weeks and report back.

Let me know how it works for you. I've found that it works better with good strong veg lighting than it does with barely adequate illumination.
So are we concluding that an unnatural lighting cycle is actually more benefitial for cannabis than just x amount of straight light, regardless of spectrum, intensity or "flower initiators"?
And if so, what does this mean? Is the 6/2 cycle an imitation of a location a land race grows? Or is it just a hormonal/metabolism thing within the plant, like rather than eating your days food at once for us humans, we seperate it into 3 square meals?

My guess- and that's all it is- is that plants like a little rest and grow fastest when they've had one. Some say this is a way to eliminate 'mid day depression', when growth slows. Maybe it's cooling the plants into thinking (hormonally speaking) the days are going by fast and that it needs to keep up.
I could go with that, I wish Id done a degree in horticulture and botany now! This stuff is so interesting.

They do fine as long as it's a cycle that coincides with 24 hours. Using odd ones that don't add up to 24 might cause problems, I don't know, never tried it, just read that somewhere. I can't say for sure if 6/2 works better than 18/6, I just figure that since plants elongate in darkness that short dark periods would be better for keeping stems short. Also, when changing to flower mode it may be better for them to go from 6 hours light per cycle to 12 than from 18 down to 12. Just a hunch.

No one is talking about DLI (daily light integral).
If you have bright lights exceeding your dli target in a straight 18 hour period, then 6/2 might offer real benefits.
How long does it take a plant to fall asleep and wake up? Transitional periods might cut into you light period.
Can we hasten the sleep/wake time with far red manipulation?

I was just thinking this.... maybe 2h isn't enough sleep? If I follow the leaves after light off, the drooping of leafs takes 30min+ ? Another 30min for them to go back up so we have just 1h of rest?

Do not confuse Day Light Integral with Critical Day Length. DLI is just a measurement of how much photosynthetic radiation falls upon a given area. It is usually measured in Moles per meter square per day. Depending on a number of variables (IE: Geographical location, weather conditions, season, and time day) DLI can be as high as 60 outdoors and 30 in green houses.
As it has been stated before in this thread and another thread.. Long day / short night plants like a tomato need longer days to flower. Short day / long night plants like cannabis need long nights to flower. The longer nights give cannabis and other "Short day plants" more time to produce flower clusters.

No confusion here (dont worry ill be confused again soon enough). Cumulative ppfd(which is per second) over a 24 hour period - How is this not relevant to a veg lighting discussion? Light intensity has barely been mentioned in this thread and its crucial to choosing light duration. Maybe DLI is outdated but can be useful.
1000ppfd over
16hrs - 58dli
18hrs - 65dli
20hrs - 72dli
1300ppfd over 18hrs is an 84dli.
How intense is the lighting. Are you exceeding reasonable DLI goals before your photoperiod is finished? If so then youre wasting electricity and risk photoinhibition.

Is this only used in flower or veg, and what are the hourly differences?

Just use a digital cycle timer. Plants can't tell time, cycles that don't square with 24 hours still work fine.
Why are you putting up guesswork as factual information? It's clear you don't know.

Oh, you're a fucking expert on plant science now are ya ddipstikk? Let's put it this way then, you COULD use cycles not totaling 24 hours but then you'd have to buy a special kind of timer, if you can even find one, and it's highly unlikely that it would be of any benefit anyway.

First, you've made an assumption that you've already admitted you know nothing about- so my comments about your habitually running your mouth about things you know nothing about stands.
Second, such cycle timers aren't hard to find and in fact I own one. The simplest one is a digital timer that can be set for weekly operation, these aren't expensive.
Finally, I know what I know- and I know what I don't. You clearly don't. Thus the credibility problem.
