Will infrared light cause problems during flower?

Ignorant to say that green light doesn't have any effect, sounding like a douche while doing so, however, is impressive. Did you even read the article you posted?? Good article, not sure where the quoted text came from..
Where did I say it has no effect?

Still wrong
... That's accurate info. Don't ask for help if you're going to disregard valid responses dude. I'm not usually such a dick and I am sorry about that but you're making it very easy for people to not want to respond to your questions. Just being honest.

Never once did I say green light has no effect. I was giving valid responses. And your telling me that the facts are wrong.
I have ran a green light through dark period. Plants went into bloom, they grew and I harvested them. No issues with having the green light on. Just needs to be the correct bulb. Actually green light not just coated.
Grower talent is hard to come by. I see a lot of misinformation on here.

How do plants use green light?
Do you know why plants are green?
Sounds like you're saying that plants don't use green lights while - where my like a douche statement came from - reflecting the light, hence why they're green.
Yeah cause all those LED companies are advertising how much green the have.

"Leaves appear green because they reflect green, while absorbing all other colors of light.
You then sarcasticly refer to the lack of green spectrum in led lights, which leads us to assume that you believe it's useless.

What you implied was that because plants are green that light is reflected and therefore not used or seen by the plant.

There are LED companies who have been in the plant lighting game since the beginning who use a fairly high ratio of green in their spectrum, they do so on the back of NASA research.

There are plenty of non dumbed down articles on green light and how its used for photosynthesis , although at a lesser degree then other parts of the spectrum.
There are also lots of articles about other uses like shade avoidance but the degree of stretch greatly depends on the presence or lack of other parts of the spectrum.
Plants have been grown in past studies using only green, only red and only blue. They grow just less efficiently.

You may well have grown with a green light in the background and ad no issue. Doesn't mean the next 50 strains you grow will go the same way.
Its just using best practice to minimise risk to not have constant light of any kind in the dark period.

Thanks for your two cents. Also for putting everything that I have already stated or is in the article I posted. I grow multiple strains at a time. I have done this to many different strains from different sources. Please show me some LED companies that say their light is better because of there green spectrum.

Back to the OP. I also had a temperature controller display red all through my first grow. It was right next to the plants. No issues. I have a humidity controller that is much brighter but green. Same thing no issues.
*This is just my experience over the years and am in no way telling anyone to do exactly what I say.*

HydroGrowLights have been doing it for decades and most of the lighting that followed were copies of their design, though its cheaper to emit the green. Also I do not endorse that company in fact I would say avoid at all costs but I think its about 17% green they use.
But you can also google the nasa published data on it.

I had the opposite experience having had to change out a power pack in my grow and forgetting to tape the red LED. Hermed the whole side of a plant and cost me 3 crops and several thousand pound.
Now I don't take chances when the other option is as simple as taping over a diode or not having them in the first place.

Anyhow the OPs point was about IR and that's an entirely different situation. That Can lead to spindling plants with longer internode spacing.

This is the most accurate response, as far as actual Intel goes. Plants use green light as a sort of tool, like a measuring tape, to see where the sun is hitting it to grow its branches accordingly. While it's effect on actual growth is minimal, it certainly does have an impact on how and where that growth occurs. Less green means more 'shade' to the plant, forcing it to stretch. Lollipop with only a few main colas? Probably no problem. Grow without training and you'll have all the small branches reaching for the light without adding any potential bud spots on the stem. More green essentially equals more growth spots.
Lollipop killed master kush yield 65%

You boys play nice, ya hear?!

To answer your original question (kind of) @newbie2323, IR light is prevalent naturally in late summer- a bit at sunrise, and a lot at sunset, and that tells me plants Love IR during flower, but not after lights out. The Leds on your lights are likely meaningless to the grow because of low intensity but covering them is a good idea.
My plants get an IR bath pre sunrise and post sunset. Does it work? Who knows.?! But I love sitting in the grow room when the IR light comes on 15 minutes before the big light goes out. And then it’s just IR for 15 minutes more. The most peaceful time in the garden

Keep at it and you’ll learn a lot. Enjoy your harvest.

But im guessing if I should cut the strech your seeing on one of those plants just to keep the canopy the same, im about 8 days into flower. I also have 5 smaller plants i decided to germinate, but I threw them into flower the same time as the larger plants. These are grown from seed and I was given them. I was to there autos but im doubting this. Indica strain and they're happy , smell great and look healthy. Im sure ill get a good yeld.
