I'm guessing those are the 700nm diodes
Looks like one LED in each cube isn't lit..what's up with that or am I missing something ?
yes its the 700nm its inferred, we humans cant see it, farered is the 660nm
so what your saying, is that the 630nm is the "most" important/effectiv for flowering ?
I was in the believe it was the 640nm of course supported by 630 and even 620
and that the 660 (as I read, I believe, is fare red ?) is for the "Emerson" effect or sumthing a like
the 700nm was to mix in some inferred (was`t to sure about that one, knew I should have done even more research)
the 6500K was to both have some "true white" to hit all the spectrum and to make up for the lack of blue`s, had to skip two to get one more 640 and one more 660 in to the mixture and since I veg with T5HO in 6500K it also make sense to use, as fare as I know 6500K is also more "effective" then other whites (etc. warm white/2700k)
what would be your mixture if you should put 120x3W together and you had a box full of all the chips/LEDs you could imagine![]()

Several White LEDs available for the last couple years provide as much PAR as B/Rs.
The problem (of false science) stems from R/Bs were the first diodes made and some idiot (with pseudo authority) sold the mj lighting industry the idea that the only spectrums mmj needs are the R/B peaks, AND, the rest are a waste, including that Green was not important.
I showed you where the important flowering spectrum is 630. And since WW can produce ample 630, well, the spectrum beyond it is not the be-all-end-all. In fact there are several completed grows using only CREE WWs, which coincidentally have a broad 630
Undoing that early programming has been difficult, but the winds are changing.
I think it's possible. I'm working on LED panels. Next LED project will be mostly whites with red/blue in lower ratio like 10 white:4 red:2 blue. I like having more white in a spectrum than red/blue.Fonzarelli- Do you think it's possible to mimic your results with only LED's? Have you ever tried in the past?
ETA: Have you ever tried supplementing the sun itself with LED light?
Reboot your computer (aka, brain). Due to HUGE advancements in white diodes,
What huge advancement? AFAIK white LEDs still only contain 1 single blue peak and mostly yellow/green wavelengths, except for a few WW and NW that peak at 630nm. What advancements have they made since XML or XTE?
