12/1 lighting--Any truth or banana in the tail pipe?

[CocoNut 420]

More light ime = more bud but with a time penalty.

10/14 or 13/11 offers faster into full flowering mode therfore quicker.

Yes definitely very interesting. To try
Could we consider 12-1 for autoflower?

If you grow garbage, hemp-polypoly-hybrids... does it really matter? Will you even be able to tell a difference? I dont think so. If you cant tell good weed from hempy-junk, I would not be confident you can tell the difference in 12-1 lighting and the zombie grower light schedules. This is not some personal attack either. You're just another victim of cannabis disinformation, created by people that seek to exploit you. But a little light leaked in, and you found 12-1. That's a start... but dont think it ends there. The seeds you are growing are just as bullshit as the light schedules you used to believe in. There is no special cannabis botany. There is only botany. You want to learn how to grow plants, study horticulture, not some corporate shill on youtube wearing a high times hat promoting polyhybrid inbred selfed feminized GMO seeds with their genetic marker. They even make fake seeds now through tissue culture with an optional fake shell.

Fuck all those GMO seeds.

Give me mother nature dude. Just the same as our relationship with this plant has been for hundreds of thousands of years. I dont eat GMO foods, why would I smoke it?

It does matter because less light usually equals less growth and less yield. So unless you are growing equatorial longflowering NLD sativa's it matters.

That's why in horticulture greenhouses are added extra lights here in the north, to increase the light hours in winter, to still have a descent harvest of cucumbers or tomato's.

This also means if you veg with 13 hours (which 12/1 basically is), it takes longer for the plant to develop to the same size then with 16-18 hours light.

So what's the use of 12/1 then? You don't spare energy as vegging just takes longer to get to the same size?

Or when you just reduce yields with non-photoperiod autoflowers due to a lower ammount of light?

Ofcourse 12/1 works, I just don't see the use for it, as it doesn't provide much advantage to the traditional methods.

If nature is your guide - a philosophy I can support - then 12/1 also doesn't make sense. No country in the world it gets 1 hour sunny in the middle of the night. Nothing natural about it...

You dont realize how boring this subject is to me but I'll briefly answer anyway. Nature... Just like in the picture I provided has intense light for about 8 hours. Adding an hour of light in the dark period is called "photoperiodic control" this is not nature, but a technique to keep plants in veg. That's artificial, not natural. Generally, nature gives plants in good situations 8 hours of intense light. The plant has spent millions of years being in harmony with this. Now you want to use 2 suns out of pure greed. A lot of people tear leaves off the plant out of greed too. Like rats clawing at it. Thinking that removing the stored energy in that leaf results in more bud. That makes a lot of sense. The plant puts effort and energy into making that leaf as storage for energy that it uses up to make flowers. It's a known fact that marijuana grown with 12-1 in veg and 8 -16 for Sativas, 6-18 for indicas yield more and are more resinous. The plants are happier, healthier. They are getting what they are used getting to for millions of years. Only in seedling stage would I use 16 hours of light. Any greenhouse that is using 12-1, 8-16 is going to stay in business while everyone else who traded horticultural science for a belief system loses their ass on electricity, fertilizers, more water is evaporating into the air, air conditioning, pest control etc. I see where people think more light is better but it's a misconception that cannabis like light.

Cannabis loves the DARKNESS
It only needs the light to survive. Just like you going to work, the plant is working in the light in the sun, but it wants to tank up, then relax and chill...not work all day. Imagine you have to work 16 hours a day. Would you be giving your best? Not at all bro. Stand under a high intensity light for 24 hours and see how you feel.

Here is the thing. Under 8 hours of intense light, the plant is full, it's done. Photosynthesis stops even if the light is still there, the plant goes into photoperiodic protection. C02 is no longer being converted.

If you got some plants on 16 hours of light, use your damn eyes and look at it.

When the light comes on its leaves are held up ready for light. At hour 13,14 some plants will visibly droop, not all. Their branches are gummy flexible, leaves hanging down a little, its passed out doing nothing. What is the point of blasting it with light when it's doing nothing? It's a waste of energy and resources. Some plants dont droop, but it doesnt mean photoprotection has not taken place. Test it. See if there is any photosynthesis goin on at hour 14. If you got the proper amount of light, at hour 14 your plant is snoozing and you are pounding it with light for no reason.

What kind of genetics are you people looking at anyway? Dutch treat? Inbred Poly-poly-hybrids chemically induced to hermaphroditism to make feminized seeds?

(Just take a second to look at that description again... does that seem like high quality to you?)

Anybody growing that junk has nothing relevant to say about results with actual marijuanna plants producing sensi. Nothing. They can talk GMO cannabis with other zombie growers, that's it.

Nonsense, as you cannot compare the two. Even on a clouded day the sun provides much more light intensity then most artificial lights. Depending on the season and location plants get more then 8 hours light of different intensities.

If you really want to grow in "natural harmony" then just don't use any artificial lights at all.

It's a known fact that marijuana grown with 12-1 in veg and 8 -16 for Sativas, 6-18 for indicas yield more and are more resinous. The plants are happier, healthier.

Known by whom? Can you provide any evidence to support this claim?

From personal observation 12/1 leads to pro-longed veg and pretty much the same yield after flowering as to expect for a certain strain. But this is by no means a scientific observation ofcourse.

It's an assumption you make, but provide no prove for it.

Only in seedling stage would I use 16 hours of light. Any greenhouse that is using 12-1, 8-16 is going to stay in business while everyone else who traded horticultural science for a belief system loses their ass on electricity, fertilizers, more water is evaporating into the air, air conditioning, pest control etc.

Farmers here are among the most efficient in the world. They are subject to all kind of regulations and need to make profit, so always try to find the best energy versus yield ratio. They would not use the extra lightning if this was not necesarry, as it cost them profits.

These are not growing cannabis ofcourse. But it does point out that more light, usually means more yield with most plants.

I see where people think more light is better but it's a misconception that cannabis like light.

Try growing a cannabis plant without light then.

It only needs the light to survive. Just like you going to work, the plant is working in the light in the sun, but it wants to tank up, then relax and chill...not work all day. Imagine you have to work 16 hours a day. Would you be giving your best? Not at all bro. Stand under a high intensity light for 24 hours and see how you feel.

I agree that it is probably better to have a dark period. But I doubt it matters for the plant if its a full 11 hours or 6 hours during veg.

The comparison makes as much sense as to say "go stand with bare feets in wet soil for 24h and see how you feel".

You could just aswell ask how you would like it if you sleep and they wake you up every time in the middle of the night for one hour. You probably wouldn't like that either and get stressed.

Partly I agree with you its better to have a dark period, but without any science to back it up it doesn't mean much.

Many cash croppers use 24h of light in veg and they also seem to have good results.

So I'm open for any evidence behind those claims. For me personally its not about being "in harmony with nature", but about efficiency: how to get the best yield/quality with the least energy input.

Test it. See if there is any photosynthesis goin on at hour 14.

I'm by no means a scientist or elite grower. I can only talk from my own observations.

In regard of 12/1 what I tried many times, it always seem to slow down the veg period.

Outside that I don't see much difference in the plants between the other light schedules; they look happy and healthy anyhow.

So that's why I don't see use for it anymore. It just makes the grow take longer, which summs up to the same energy costs. It doesn't make sense to me.

To a lot of other people it doesn't seem to make much sense either, else any cash cropper would use 12/1.

The traditional light schedules are probably used because they are the most effective, as they are growing pot indoors for decades now. So I guess people before us would have figured it out already if 12/1 would lead to monsteryields at less costs. But this doesn't seem to be the case.

What kind of genetics are you people looking at anyway? Dutch treat? Inbred Poly-poly-hybrids chemically induced to hermaphroditism to make feminized seeds?
(Just take a second to look at that description again... does that seem like high quality to you?)

I probably don't have acces to the elite genetics you are growing, but I don't like to limit myself if it comes to genetics.

Most fun I get on trying as much different things as possible: (poly)hybrids, oldschool Dutch strains, unworked landraces, equatorial sativa's, indica's and anything in between. Feminized and regular - it doesn't matter to me.

I share your dislike for autoflowers, but even those have their place for those who like it.

But all those strains have basically the same outcome in those light schedules.

The only thing I noticed with some genetics under 12/1, is that they get "confused" as they get extreme pre-flowering. Which indicates stress to a amateur hobbygrower like me. But most take it as any other light schedule...

To be clear: not trying to be a smart ass, just sharing my own experiences for those who want to listen.

Sembra interessante, risparmiare sulla corrente non mi dispiacerebbe, resto in attesa di notizie
