GAS lantern Schedule & Diminished light

Just noticed this; There is much to consider when discussing "yield", prolonged veg does nothing but decrease said "yield". This is from a "net annual" perspective. Again, from experience, point of diminishing returns.
I agree but some individuals prefer the technique. It was just my theoryism ha

So if we are to assume there are "diminishing returns" when it comes to veg time:yield, how do we work out what optimum veg time is? Is that strain dependant? And obviously variable dependant, eg plant stress and vigorous growth. But hypothetically, if all things controlled what is ideal?

been usin it for years and know several others usin it as well. No one I know that has tried it has gone back as the pros far outweigh the cons
just switched my current crop to flowering and trying 5.5/1/5.5/12 lighting for the first time. what effect does this have on yield?what are the pros and cons of this style?

For flowering...If you set your timer for : 5.5 on/ 1 off/ 5.5on/ 12 off... you are essentially giving your plants a total of 11 hour days and 13 hour nights or one long day a short night and then a short day followed by a long night.

As it has been stated a number of times already... Longer nights will allow "Short Day" plants, like cannabis, more time to produce flower clusters. More flower clusters means your overall dry weight will be heavier.

Is this only used in flower or veg, and what are the hourly differences?
(Gas Lantern Schedule: This keeps plants from going into a flowering mode during the night time. This also used my numerous large scale, commercial, greenhouses)
12 on/ 5.5off/ 1on/ 5.5off is for the vegetative phase.

(Diminished Light: Mimics what happens in nature... Unless you live on the equator. In the fall/winter seasons have you ever wondered why the sunsets gradually earlier)
Flowering starts at 11on/ 13off and gradually the night gets longer as the days get shorter.

I've been running 6 hours on, 2 off three times a day for a month or two now and I think the ladies like it. They stay in veg and grow vigorously.

The biggest is it reduces the stretch and in turn plants finish faster

It's effective in my veg space right now. I am running high light intensity in my veg, without which I don't think it would work nearly so well.

Having related this a couple times, it occurs to me to ask where the idea of low light levels in veg got started, anyway? I sure don't like the results compared to higher intensity!
What hours do you guys use in veg vs flower? How many of what hour intervals? Thanks

I now veg with 3/1 and flower with 11.5 hours light the first week, 13 for weeks 2-8 and 12 for weeks 9-10. 12 is more of a ripening cycle than an active growth cycle. 13 produces "rapid formation of new florets" according to this from a David Potter article. Whether or not the floret formation would be the same with 12 hours at the same growth stage I don't know. It looks similar from the table, since the indoor was on 12 hours the whole time. I just figure more light = more growth. It looks like even 13.5 could be used, but I don't want to push it that far.


This from the same article shows that the day length is 13 hours in Mazar on Sept 1, so should be good for flowering most Indicas and hybrids.

Those look exactly like normal 7 week buds, except the hairs got browned, probably from low humidity or the UV all the time. You barely even see hairs when a plant is really done, because they retract into the calyxes. Those are a bunch of hairy underinflated calyxes. There's more leaf than calyx. .
BIG Thanks man. This quote answered so many questions for me.

What I posted earlier earlier about using 13 hours, my last buds did come out pretty fluffy. I don't know if that was why or not, possible though. I think I better just stick with 12. I did read on some site that growers found that 13 hours made buds fluffier and leafier. Probably true, at least in many strains. My plants did get pretty damn leafy.

@ttystikk I'm going to try that 6/2×3 for veg on my next run.
I'm always "trying" new and different things..
I'm currently flowering under 9.25/14.75 on/Off. And it seems like the indica and indica doms like it, some loss in structure but are packing on some tight almost fist size buds at week five'ish.
The sativas/sativa doms don't like it.. Tiny nugs spaced far apart ( Crystally as hell though.. ) I'm flowering under both mh. And h.p.s. 600's

I have indeed seen that outside, sure. I've seen some plants finish in August already. (My mind still struggles with that one.)

Inside I've just always started 11.5/12.5 or 11/13.
12/12 corresponds with Sept 21, easily a month into an outdoor flowering schedule. Running even shorter day cycle just reduces DLI and chips away at total yield potential. At least, that's my experience.

You sure those August finishers weren't autos?
