green light spectrum?

I am using logic in everything I say here. You seem to be twisting logic all around until it fits in to what you are trying to prove, and I still haven't heard exactly what that is.

Missing light is exactly that: an absence of light. What exactly is the missing spectrum that you're talking about? Is it UV/Near UV? UV is not entirely missing from the spectrum when an HPS is used in the flower room. It sure isn't missing from the spectrum my outdoor plants are getting. You were mentioning using a blue light source at night, but if you're talking black light, it doesn't exactly fall into the blue category. And what exactly is "true light"?

When photosynthesis isn't happening, the plant has other functions it can focus on. A lot is going on under the surface at night.

Maybe more people will be able to afford "high end lights" if you stop filling their heads with the idea that they need to line their grow rooms with black lighting instead.

first i did not say use a blacklight the entire time.just at lights off!true light is light with all the spectrums.and when the light is off how does it know that the lights are off? it has to be a spectrum if you can use any color but red!when the lights are off!shined on the plants and the flower period want change.again how does it know that it is dark?

What is the difference on whether or not you use it the entire time. And please, answer Why do you even run it at all? Is there any benefit to running it? Have you run a side by side trial with two clones to prove to yourself and others such as me that there is a benefit. Others have played with black lights since the dawn of indoor growing without getting any wonderful results.

The plant has receptors for light. When they sense light it is light, when they sense no light it is dark.

If you want to keep pressing the argument that any colour but red is OK during lights out then you should find a CFL with the coolest blue spectrum you can find and just leave it on at night to prove it. You keep dodging all of my questions and keep repeating what you've already claimed.

I'll check it out, I'm sure I'll feel enlightened and refreshed when I finish reading it.

It kind of points a finger back at yourself when you misspell Einstein in a sentence with no punctuation. Although when you do attempt the punctuation thing it seems to turn out like this:

it has to be a spectrum if you can use any color but red!when the lights are off!shined on the plants and the flower period want change.again how does it know that it is dark?

Brutal, man...your "new" thread is basically a copy of this thread with no new info or questions. Blatantly fishing for other people who will agree entirely with you, while labeling anyone who disagrees with your "logic" as still thinking the world is flat.

Here are two simple tests you can do to test to see if your main arguments are true:

-If only red spectrum light will disturb the flowering cycle, run a blue spectrum bulb during lights out to show that pot can't "tell the time" through blue light.

-If plants do any sort of effective photosynthesis under a black light, then use one for your veg cycle. Not at night, but as the main light source.

Plenty of people have flowered plants with metal halides without the plant's wristwatch grinding to a halt. Have you done a grow without the black lights that you can even compare it to? Are you going to try any tests to even determine whether or not you're spewing diarrhea from your wordhole? Are you going to answer a single question that I've asked with more than a one-liner that I need an Enigma machine to decode, only to find that it still contains no relevant information?

I've seen some pretty interesting debates on the topic of UV light, but why no cannabis grower has tested it out yet is beyond me.

... and this is why we need a controlled experiments section, so people would stop posting claims without evidence backing it up. The OP talks about using logic but isn't it common sense to have a control group when doing an experiment? Otherwise how do you know if it actually made any difference?

i have tested and still testing

I think the key word there was Controlled.

A few direct questions:

Why is red the only spectrum left?

What do you mean by "green light", incandescent party bulbs?

Why do plants not flower automatically when grown under only blue lights since they are also lacking red spectrum?

One more:

Are you trying to say that it's a lack of red light spectrum that induces flowering?

I think OP may be on to something but without correct testing no one will ever know.

my belief is that the plant flowers because each day it records the amount of light it receives in the pigments and compares it to the previous day. When that amount of light starts to decrease it will flower regardless of hours of dark.
This is just a hypothesis and I haven't setup a room to test it yet.

But I never thought about spectrums, just total light.

Yeah, this is kinda my thing. The claims seem to indirectly refute things I have read from top notch sources, however indirectly, so it's really hard to draw a conclusion. This is why in the absence of real scientific testing, I keep asking for some sort of source which might lead to logic that would extend to what we are all doing on this site. All I continue to hear are arguments which don't jive with what I know to be true, and testing using incredibly flawed methodology. I'll go take a look at your new post, perhaps you will address some of these questions using real science...

This is precisely what he is trying to say. Basically, boiled down, he is saying that you can provide as much light in any spectrum lower than 600nm and will induce flowering as well as increase the productivity of the plant by providing it all this extra light when normally it would be dark. Basically that he's discovered the secret to improving flowering that no one who has grown has ever written about or disseminated.

to boil it down using Mel Frank's and Ed Rosenthal's explanation of what causes flowering, the hormone which triggers flowering is ONLY degraded by light with a longer wavelength than ~620nm.

thank thank you thank finaly some one who understands my logic! yes the plant measure the light from yesterday and when it starts to get less light it flowers.but its the red that it measures.not the other spectrums i know this for a fact! because on my plants when I use a blue spectrum on them only when the lights are off,I can still make them flower.is that not light?why do they think its dark and flower anway?

Ok, we need proof then. The only Only ONLY thing you have is words coming out of your mouth.

A blacklight is not the 'blue' spectrum... Do you ever wonder why they make 2 types of grow lights. HPS and MH. One for veg and one of flower.
A HPS is more of the red end of the spectrum
A MH is more of the blue end of the spectrum

Why don't you try your expirament with the REALY blue spectrum. Where a plant can use the light.

I've already said this:
THE REASON YOU CAN MAKE THEM FLOWER WITH A BLACKLIGHT ON DURING THE 'DARK' PERIOD IS BECAUSE THE BLACKLIGHT PUTS OUT NO USEABLE LIGHT FOR THE PLANT! JUST LIKE YOU WERE TALKING ABOUT WITH THE GREEN LIGHT!

ricardezra said:

no marijuana does not use green spectrum that is why when lights are off you can use a green light and it wont effect the flower they are not harmed!

EXACTLY EXACTLY EXACTLY THE SAME AS A BLACKLIGHT. MARIJUANA DOES NOT USE THAT 'SPECTRUM' OF LIGHT.....


Here, go ckeck out this site (>>> http://www.kbcarstuff.com/HID-Kelvin-Temperature-FAQ-s/211.htm <<<) and read that small little paragraph.
I'll copy and paste the important part right under this.

"HID COLOR TEMPERATURE FAQ (Kelvin Rating)

Color Temperature is a measurement in Degrees Kelvin that indicates the hue of a specific type of light source. Many people believe the misconception that colour temperature is a rating of the brightness of the bulb or HID kit. This belief is completely false. The reality of the matter is that the higher the colour temperature, the less use able light output you will obtain. A perfect example would be a black light. This light has a colour temperature of approx 12,000k and has almost no useable light or lumens output."



A blacklight has a color temperature of 12,000 K..... Tell me, where would your blacklight fit on this chart?????

Unless you can show us PROOF instead of just word of mouth, this thread needs to be closed. You keep saying you have proof, yet nobody's seen anything of the sort. No more mis-informations needs to be running around. There's enough of that already.

Then how come seasonal flowering plants grown under only blue light (vegging) their whole life, do not flower until they get 12 hours of darkness? By your reasoning, this would tell them they are left in total (time telling) darkness. They are having an extreme lack of red light, yet do not flower. If lack of red light causes plants to flower, what's going on here?

If the blue light was just as safe, why don't you use them during the dark period instead of the black light? Of the same wattage, I guarantee that any blue spectrum bulb is going to put out way more lumens (likely enough to affect flowering, hint. hint. that's the key) than a thickly coated black light bulb.

It would only add further proof to your hypothesis. If you do things like this, you need to do the exact same thing to another plant, but without the extra light on in the darkness for a control. Ideally, you'd want to use clones from all the same mother, and the whole experiment in one cab or room with a light dividing wall (with no light leaks), and as near to the same temp., humidity, etc... All of that's really only necessary though, only if you want to be positive of your results and have a sound experiment that others can duplicate to prove your hypothesis, and have it accepted as a theory. It's not necessary for the purposes of fantasy, magic, voodoo, make-believe, or old wive's tales, though.

Proving that your plants can handle a weak black light during the dark period without receiving enough stress to go asexual, does not prove that red light is the only light that tells a plant when to flower. It may offer very little support to it, but to me all it says is that your plants were healthy and of hardy enough genetics, to handle a little light pollution like all plants are ideally supposed to be able to do.

Hell, by your theory, people could build greenhouses with red filtering sections or rooms and trick plants into harvesting year round, while staying in the sun.
