Man so close. But from what I see they are together.Like these ;
Adlite Series | UV, IR, and Deep Red Plant Grow Lights - Mars Hydro
Discover our Adlite Series Led grow lights. UV light plays a crucial role in stimulating the production of secondary metabolites in plants. IR light aids in photosynthesis and overall plant development. Deep Red light is crucial for the flowering and fruiting stages, promoting larger yields...www.mars-hydro.com
I meant to add more but I passed out lol.Yes it is important. I believe in Bruce bigbee work about it
What?? Just because op said the word infrared, look up the 730 nanometers the op is talking about and you see that's not really infrared but more far red or deep red, and has proven benefits in multiple studies.Viper,
Plants reflect all infrared radiation. The only benefit you might be able to rightfully claim is that your bulbs emitting infrared will help maintain temperature in a tent.
Zill.
Exactly, thank you. You said it, you can't say all "infrared" is the same because of how wide this band is.Interesting discussion.
This has nothing to do with the wavelengths plants can use, but all this talk of infrared = heat is wrong. SOME infrared is heat, but the infrared spectrum is very wide -- much wider than the visible spectrum. Near infrared light is not heat. Healthy, green vegetation tends to reflect a lot of it, and we use it in aerial imagery to track plant diseases and pests on a large scale.
400-700=PAR, 400-750=ePAR brotherregardless of what was said above, 730nm is Far Red and does have impact on the plants. You can get additional photosynthesis via the Emerson effect. You can change plant morphology as far red signals to the plant it is in shade. You can potentially have a higher DLI in flower using Far Red to put the plants to sleep faster.
When people hear iR they think light outside the par spectrum which is just heat. But 730nm is in the par range, just not the classic 400-700.
If I had far red built in to my primary light I would want separate control over that channel both intensity and on off time and be at least 60W in a 4x4 space or I would just use external lights anyhow. So make it useable or don’t add it. If it comes on with the main light and no other control is provided I see this as a big negative and would prevent me from buying the light.
you can grow with infra red? legendary.. but seriously though NASA funded research concluded far-red 730nm does help with enhanced cell expansion rate in lettuce, for cannabis it helps you grow taller plantsHello THC growers, ViparSpectra would like to take a quick easy survey with you, which will take only 30 seconds.
Q: Based on your experience, do you think infrared diodes, usually 730nm are necessary to include on LED grow light?
What's your answer? And why? Thank you.
Yeah, I think you were the first one to bring that to my attention a while ago. Yes, frustrating that manufactures use one label and growers use another term.Technically Far Red is not infra-red.
Far-red light is a range of light at the extreme red end of the visible spectrum, just before infra-red light. Usually regarded as the region between 700 and 750 nm wavelength, it is dimly visible to human eyes. It is largely reflected or transmitted by plants because of the absorbance spectrum of chlorophyll, and it is perceived by the plant photoreceptorphytochrome. However, some organisms can use it as a source of energy in photosynthesis.
Infrared is not visible to the human eye. Far red is to most people. It’s the buffer zone between viable and non visible spectrum.
A lot is reflected by healthy green cannabis which is why a healthy dose (60 Watts in a 4x4 space in my experience is the minimum effective amount to impact the entire 4x4 space) is needed to see effects in flower. As seedlings much less is needed.
But I see a lot of manufacturers use Infrared rather than Far Red to describe their 730nm leds. Maybe there is more than one definition of infrared depending on the continent you are standing on. That’s gotta be frustrating for new growers to understand all this minutia
They are separately controlled by a switch, but the sake of automation you just use one for one and another for the other?Man so close. But from what I see they are together.
I could see using them as far red in veg thru first couple weeks of flower then switch to uv for the back half of flower. Could work and you need less hardware in your grow space.They are separately controlled by a switch, but the sake of automation you just use one for one and another for the other?
It would take two fixtures to separately control them.
Extended par range now includes some uva too depending on who you ask.400-700=PAR, 400-750=ePAR brother
whats the benefit of far red in veg thoI could see using them as far red in veg thru first couple weeks of flower then switch to uv for the back half of flower. Could work and you need less hardware in your grow space.
Plant morphology primarily. Bigger bush starts at the first node.whats the benefit of far red in veg tho
You are wrong. https://youtu.be/sS7aAcacfgkGreenGalaxy,
At the very serious risk of being dipped into a cauldron of molten silver....
Infar red/red is not part of the photosynthetic action spectra. None of light harvesting pigments respond to anything longer than 700nm, see below. However, there are binary photoreceptors called phytochromes that exist in two forms depending on whether it received red or far-red light. It triggers changes in plants development. It has nothing to do with photosynthesis. And by the way if you dowse the plant with a reddish light won't you keep those phytochromes in one state only and totally screw up your precious cannabis plants?
