If only there was a way
I think you misunderstood his point. Of course it would matter if you provided only 1 wavelength of light, but when it comes to broad spectrum emitters, intensity becomes the driving factor...just like with sunlight.
That is quickly falsified. Try growing some bud with 532nm lasers.
Of course spectrum matters!
Meh... I suppose it's possible. I'm looking at the detail, he's talking subjectively.
Not subjectively, more like conceptually. I have never referenced or supported an outrageous or completely contradictory to accepted spectrum. Just that whites as a base are the best in performance. White led's can supply more photons over the whole canopy while hitting major chlorophyll peaks and accessory pigments. With a little red enhancement to the chosen white base it produces the most successful match to sunlight growth from any led spectrum I have ever seen. That I base off multiple monochromatic and "full" spectrum white configurations spectrums, and years of outdoor growing.
Distinction without difference?
That is the part of your prior note which causes my antennae to go up.
The only information that he has to refute this is a bunch of bollocks and tardwinker.Distinction without difference?

Is there a difference between a red photon and a blue one according to your definition, for the purposes of photosynthesis?
If so, what are these superfluous photons doing? The fact of the matter is one can make white light from only two narrow-band sources, if needs dictate, so I don't understand this "white light photon" you are talking about and how there can be more.
Unless you are referring to the lumen:Watt ratio. But even then, dichromatic sources are more efficient IIRC, precluding something revolutionary happening in the last 6 months of which I am unaware .
Furthermore, what kind of white-LEDs are you referring to? Phosphors or Polychromatic blends?
Don't get me wrong, "white" LEDs are great as a supplemental catch-all, but I wouldn't call them essential in relation to the targeted frequencies. You're wasting lumen$...we're interested in chemical properties, not how make-up looks.
One thing I can say after ~15mths of experimentation, a red/blue exclusive-blend lacks in the back end of a plant cycle. The moment I implemented a different fixture which contained a single, green LED in the matrix (it's a 5x5 multichip) in lieu of one of the reds*, I perceived a positive change in the plant development. It also made the garden look more 'natural' (as the math dictates), but it certainly wasn't "white". One plant in particular which seemed to show a strong change was a parsley I have under it--but that's a different tale.
Unfortunately, it burned out after a week either due to the power supply being faulty (causing the prior LED to burn out, too) or a poor thermal contact during replacement (more likely). So data collection is halted, for now. I have another one and a spare power supply (I thought ahead when getting my original "warranty" part), but I am hesitant to toss them in the light in case it happens again because of some other factor, like the proximity of the power supplies to that chip causing heat issues. Yet it worked for over a year that way, so maybe it's not the design itself, just the cheapo-chinese ® components. In any event, they still have the other original MC keeping them alive while I ponder.
In conclusion, Green is an exotic spice.
Red & Blue are Meat & Potatoes.
White photons are rays-ist
*I could be wrong on the colour switched
If white LEDs were catch all, why is area 51 using reds too?
You think your the only one with good results /facepalm
Actually there's a whole bunch of us now asswipious maximus
yeah cumswapper, I have great results myself. I didn't say your results were bad but you love to be dick in everyones craw.
