Will infrared light cause problems during flower?

[newbie2323]

Hi folks - Just switched to flower on my first grow. I have an wireless IP camera in the grow tent that switches to night vision when the lights go off. It just occurred to me that the small infrared light used for the night vision could cause the plant to herm, not flower, or some other problem.

Anyone know if cannabis is sensitive to the IR spectrum?

No idea, but why?

No idea, but why?

Why do I have an IP camera in my tent? I travel for work for weeks at a time and like to be able to keep an eye on things while I'm away. Or do you mean "why night vision?" Because it came with the camera. I'll switch it off if it can cause problems. But I also just want to know.

Too much infrared light on it's own can be detrimental - plants can get a sunburn by excessive IR. But I doubt that the intensity of the IR on your security camera will affect growth. Others have asked this question on some of the other growing boards. Case and point - https://www.thcfarmer.com/threads/infrared-from-security-camera.49492/

I have seen others using the night cameras in their grows without issues so I guess it's not a problem. Commercial grows are required by the state to have them, at least out here.

Awesome. Thanks guys!

I'd put some black electrical tape over those LEDs on your monitors for sure.

Thanks. I've got translucent green tape on all lights that aren't already green

I'd never run green led's throughout the entire dark cycle. plants do use green light. I use a green headlamp if i need to do something in the room but not for long. my 2 cents

Thanks man - Better safe than sorry.

How do plants use green light?
Do you know why plants are green?

They use it for photosynthesis and shade avoidance for a start.

Botany for Dummies would be a good place for you to start. It's true that plants appear green because leaves reflect more green light than other visible wavelengths, but typically only around 5 to 10 percent of green light is reflected, and the rest is absorbed (roughly 85 percent) or transmitted (5 to 10 percent) through the leaf.

You should check out the HGL vs HLG thread where HGL uses RGB leds.

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. Think of the rainbow, what colors are there other than green? Well, there's red at one end of the spectrum and blue or violet at the other. A rainbow represents all the colors that the sun emits and that get through the Earth's atmosphere. What we perceive as white light is actually a mix of all the colors in the rainbow.

So all those colors are shining down on a plant's leaves and the plant is absorbing all but the green. Generally you can say that plants absorb primarily red (or red/orange) and blue light. It's within the chloroplasts that all this light absorbing happens."

Most green light bulbs are just coated bulbs. So the plant still can see the white light for the bulb.

This is a good article.

still wrong.

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..

lol. i thought he seemed a bit like an arrogant douche too hence the Botany for Dummies response from me.

maybe he'd understand a graph better?
as noted in the bottom left corner, the green does dip down significantly but still not below the threshold for stopping photsynthesis.

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.
