Why do grow lights have red diodes?

#shorts
660nm deep red diodes are added to LED grow lights because they are photosynthetically efficient and electrically efficient. However they are also relatively expensive compared to white LEDs so only some are added to boost the overall system efficiency but not raise the cost of the fixture too much.
660nm deep red does not effect plant shape or cause flowering to occur. Red photons are not generally photomorphogenic which means the proportion of them in the overall spectrum does not effect plant shape.

Awesome content as always! Would love for it to get to more people so myths are defunded and doubts cleared.

Red and blue being most productive. Since we have these new hyper blues and reds why not build a light with mainly 430 460 630 and 660 with just enough good 35 or 4K for visibility and fill in the gap for needed spectrum. Extra driver for dimming the blues and reds when needed. Evo mints are a nice bonus to! See there starting to float around and being used for the lower spectrum.

Solid info as always. Much appreciated.
More red early as seedlings. Progressively more blue during veg. Back to predominantly red for the final weeks.

This formula works well for me especially with cuttings, as they don’t have a taproot and you’ll need to ensure they have a solid root system before vegetative growths

Far red, deep red, IR!
Great explanation always informative 👌

What about adding a red gel in front of a light? Rosco gel or Lee gels used
for video to change the color of a light. Can be cut into strips and just cover part of a light. Or the whole light. For a few bucks.

Christmas tree grow light. Bring the light//energy to the plant or in the canopy to increase yields and reduce plant problem issues like bugs and mold. I could see it being a problem if used at 100% rate so it would be interesting to ramp up the light at intervals as needed.

Everyone’s uv diodes are burning out but photo bio leds .may as well just run leds with power veg t5 bulbs and it makes a difference

Thanks for sharing this! There's always something to learn.

we"ve come along aay since blurple, thankfully

I still think Shawn could take both of Gallagher brothers. I love these videos & I have learned so so much from them.

red light is indeed is effective but is doesnt mean that plants needs MORE red. Sunlight doesnt contain as much red light as there are in growlights. Thats probably why I never got great results with growlights on carnivorous plants compared to sunlight. I dont doubt that growlights are efficient with crops but then the main goal is production & profitability . I would love to find a growlight wich has the same % of blue, red, fard red and green as sunlight but so far noone has tested that.

Thanks for the quick explanation ☺️🤠🌮👍🤯

Can I add deep red light bars between my HPS

[ManagerGreatClips]

Does that chart represent 10$ per chip or 10$ worth of red chips per light. Cuz Cree royal blue chips are pretty expensive. Mote so then red by far..

[droidnick]

Think hecmeant to say at the end "far red does not effect plant growth "

[timpage]

Simply just to boost system efficiency.

Hi Shane! If I can choose only from luminus cxm-32 gen 4 or Chinese quantum bar with lm 301h with random bins on one plate, what’s would be perfect for this situation?

[tacosforus]

So would a blue and red only diode fixture be the most long term efficient and also upfront expensive?

[PeterKKraus]

What if all of a light's LED are 90 cri? Does supplemental red matter?

[thecsslife]

How are blue LEDs 30x more expensive than white LEDs, when a white LED is a blue LED with a phosphor coating?
