Do u know if 9/3 would have any increased growth rates too?
Yes that was my original experiment.

Hmm, I'm thinking 8 and 4 twice, or would six and six be better?
Aggressive vegging, lol Mine hit six feet BEFORE they hit the bloom trellis!
6 and 6 would give about the same veg speed as 18/6 IMHO with a power savings
Lmao gas lamp tech does not work very well. In fact it slows growth tremendously. Been there done that. . Best results come from mimicking nature. You will learn that the hard way

Where did you get that from? All normal diurnal photosynthesis cycles I saw showed peak photosynthesis in the middle of the day and less at the start and end.Plants photosynthesize most efficiently the first 6-8 hours of daylight.
GLT is drastically different in that it artificially splits a flowing length dark period while not reducing the daylight duration.
@Stephenj37826 has a solid and independently verified theory to support his approach. I intend to try it- and for what it's worth, I've also tried GLT and I agree with your assessment of it.
Gas Lantern Techniques' chief advantage is its ability to prevent full on flowering of photosensitive species in winter, so it's really more of a greenhouse technique than anything helpful from an indoor standpoint.
You'd have realized this yourself if you'd quit hating long enough to think clearly.
Yeah 6/2 is a good idea, or 5/3 to save more power. I'm going for maximum power savings with the 3/3 though. So far so good.I always like to run 6-2. Never really tried the other way though sounds interesting. A friend of mine had limited circuits so I told him to run a cfl on 18/6 and run his 400 mh 12 hours when his bloom lights where off. he said it worked out perfect.
I always used the same amount of daylight hours just split up. I've run 6 3 several cycles and in my experience is faster and closer internodal spacing. Gas lamp is different in that you aren't providing the same amount of light as 18/6 in a given 24 hr period. Also 18/6 isn't quite natural is it?
No, those charts are from experiments where they replicated a natural day, meaning starting with low PPFD and rising to a maximum in the middle (noon) and then declining. Good article though. Glad you posted it. Lots of good stuff in that one. For instance it shows how plants use all light between about 400-680 with just a slight dip in the mid 500s. It's not as concentrated in the blue and red spectrums as many believe.Where did you get that from?

I see this in the charts from the data logger of my own grows as well. The plants drink a lot more water in the middle of the "day" than at the start and end.
But IS it? Because what if Growmau5 were to veg his plants with a non-diurnal light cycle and found it was more energy efficient? Or what if he grew some autos? Those are both new territory for mau5.This autoflower/alternative day length discussion is really tedious.
Neeexxxxxtttt.
Growmau5 please save your thread from mediocrity with another compelling video.
That's not running the same amount of day light. That just makes the plants think it's shorter days. After 2 hours the plants goes into its phytochrome state. Which is full sleep mode. Like rem sleep for us. If using 730's the plants will go into phytochrome state in minutes.
That will work if you use very high PPFD levels, but if you stick with normal light intensity levels around a maximum of 800umol/s/m2 then you don't see this collapse in photosythesis.
I'm thinking about dimming and boosting the lights to create a light intensity curve like the sun would do in nature. ie less light in the "morning", most in the "afternoon" and then less again before "nightfall". The plants would get the same DLI, but I would vary the intensity over the day.
I would need to do that side-by-side though, because I doubt the differences would be big enough to be properly visual when done in sequential grows.
So can you use an arduino to control the dimming pot on a mean well driver?
