Is dark period really full dark night?

[Lalalando]

So it solves my problem.
Lets say i have plants in a room with window. There is nothing else, just plants, lights (LEDs) for growing, no other light source (little led shining from wifi, table lamp, etc.).
If I set growing lights for 12/12 light schedule, and leave window uncovered (diffuse light from outside gets into room) - I should be okay? Since in coming months like September, cannabis normally flowers, because days are shorter right?

How diffuse light at 8pm could potentially be bad indoors, if its not bad outdoors? You got me?

As long as there are no street lights, or passing cars with headlights on, should be ok.

I give up.

This is 6th grade science class man.

You also said plants don't use green spectrum light, they do.

It's just that the majority of the light spectrum they reflect is green, thus plants look green.

Stop being offensive You just did understand my question after some time, then you answered on it. And im happy with your answer since it fits my plans. lul

Thats where comes my question. In nature, cannabis in outdoor does not have 12 hours of COMPLETE darkness, so why it needs to be COMPLETE darkness indoor?

What makes you think there is no complete darkness in nature? I don't see street lights covering mountains and desert where I live. If you are referring to moonlight and starlight, that isn't powerful enough to stop a plant from flowering. But a constant light leak or LED in your tent or in your room can be strong enough to alter your plant.

If it's reflected, they don't use it.......

I wasn't being offensive, it's the gods honest truth, it's 6th grade science, and in fact you insulted millions of children by claiming their education is subpar, when you are this ignorant.

I can't help that the truth hurts but that won't make me refrain from speaking it.

You only accept his answer because it fits your plans? Lol.

Cmon boys, you can do better. Read better. Every word i write has its meaning - at least i try.
I didnt say that there is no "complete darkness in nature", i said, that there is no 12 hours of complete darkness in nature. You can check link i posted here 2 times

Mate you were explaining / answering me something I didnt ask for. You didnt understand my question at the first, thats why we get where we are now. My fault not describing the issue better. Hopefully next time

i wanted to get rid of mad boy :/

6th grade science class. C'mon.

So feel free to be the expert, I am merely trying to explain to him so that HE can understand.

The whole green light spectrum thing is fucking irrelevant anyway as it's an entirely different conversation, since you know, we seen plants as green not because of the spectrum THEY use, but because of the spectrum WE SEE, so trying to troll up an argument is a fail.

No one's mad.... except you sitting here having a tantrum and calling our education system substandard because of something YOU don't understand.

Thank you for your input! Wish you good day!

It's not irrelevant. You stated plants don't use green spectrum light. You were wrong. I corrected you. Perfectly relevant. You're the only that brought it up.

I just explained it to you....

At twilight, the light that you see, is outside of the spectrum of blues and reds, or are too weak for the plant to recognize. Just because YOU see them, does not mean that they are strong enough or in the right spectrum for the plant to utilize.

think of Solar Panels, losing power as the sun goes down.


"Just stick to what the majority of people are telling you" - reminds me of kids being shaped by school system we have lol " <---- You mean like the school system that forgot to teach you what light spectrum is and how it effects plants?

This is 6th grade science class man.

I think you should go back to 6th grade and redo it because you’re just typing diarrhea at this point.

circadian rhythm -that’s why. Plants outside are different than indoors. We trick indoor plants. Outdoor with the changing of seasoning the plants are connected to the rythym. Check it out

Obviously there is still light in the sky, there is a transitional period...and the way your eyes utilize that light is different from how a plant does....once that light drops below a certain level (I'm sure you could research light threshold in cannabis plants and find out exactly), probably nautical twilight, the intensity is too weak and the plants can begin their dark period...then the opposite takes place in the morning. The whole point of switching to 12/12 is to quicken that transitional period in the plant artificially and immediately put it into darkness. Virtually everything in regards to growing inside is going to be different than nature. That is the point. To control every aspect. If you want to set your lights to do this gradual transitional change and prolong your grow, go right ahead. The hard 12/12 just eliminates this transition - but if you have LEDs in there, or it is near a window with street lights or light from under a door coming though, that intensity is too great for the plant, even though it looks weak to you....you can see evidence of this on this site all the time. Someone is always posting a pic of their plant in a tent with LEDs causing it to reveg.

Sunlight intensity outdoors is different from a desk lamp intensity indoors obviously, but just because twilight is weak for a plant does not mean a desk lamp is weak for a plant as well.
