Regarding those two spectrums...not the same.
Look closely at red and blue spikes, the fluence light has more blue than red, gavita otherwise.
Basically it could be two identical designs, one using 3000K white leds, the other using 4000K white leds(or using 3000K + a few blue leds).


Cheers

i suppose both use 4000k + 660nm, the difference in spectrum is that fluence uses lm561c and gavita the lm301b, check the spectrum of those, the lm301b has more blue

only certain secondary metabolites are produced in a linear fashion in conjunction to nutrients and other work off reverse cues making the topic past the laws of minimums counter productive depending on what you are trying to improve production of

There is so much going on here..

I think the water penetration info isn't really showing a relationship between wavelength and depth penetration. It shows blue gets deeper than both longer and shorter waves. It's telling us something about water.


I have a big problem with the model taught to me. Perhaps I should air it.
Energy=massXspeed squared. Blue has more energy, so the mass X speed values have changed. We are told the speed is that of light so that didn't change. We are told a photon at rest has no mass. So it can't change. So how can the sum be balanced to allow the Energy to increase, while mass and speed and the function of squaring are fixed.

Perhaps I will walk away at this point. At 16 I was sent to work, to pay back my step farther for my upbringing. My physics teacher tracked down my mum because I showed such potential, but I deliver parcels now. I have missed the boat on this one, but it looks like it's sinking anyway.

So, like everything else in life, it's all interconnected. Still, it's interesting picking at this knotted ball of twine with a fork. lol

Which wavelengths, and combinations of wavelengths, are responsible for terpene and resin production?

Which wavelengths and combinations of same, are responsible for physical flower production with low leaf?

Which combinations of these will produce the maximum resin and terpenes the genetics allow, and what flower size can be accomplished along with these maximums?

So it's 2019 and we're just beginning to see a dim glow ahead. Got it. lol

Yeah, sorry for the typo, I was looking at these pictures in crop mode.

The important thing to focus on is the physiological responses of the plants/flower analysis results, and not the energy physics. The blue light ocean penetration post was to explain why the absorption peaks are higher/violet spectrum is more efficiently utilized (the first light source).

The study I linked in post #6 shows that the more UVA and blue used the more total cannabinoids and terpenes produced, the bud formation may not be as favorable (leafy) but it will be higher quality. Something else I try to rationalize also is whether the minimal increase in cannabinoids/terps (a few % tops) is worth reduced overall yield (as much of the energy is going towards leaf production).

Genetics are really the main factor to most aspects (calyx to leaf ratio, cannabinoids, terpenes).

Though genetics play a large part in how the end flower looks, I still believe there's an optimal balance to be reached for resin rich smoking flowers(Now I notice I did not include this in the title lol). There should be a general program of spectrum changes which will work with all genetics. Not necessarily ideal for all strains, but at least 'decent' enough of a place to start.

UVA and the Blues. Sounds like a band.

The blue light effect on cannabinoid study used 2 different LED, the broader spectrum one with UVA, 100% intensity blue and moderate green/yellow did have the highest totals compared to the LED with no UVA, 60% intensity blue almost no green/yellow and 100% intensity red.

Results said there was no significant difference between the 2 led systems used overall though indicating less than 60% intensity blue is probably plenty and the UVA is negligible for cannabinoids/terpenes. UVA could be working in synergy boosting photosynthesis ability of blue light similar to the emerson effect with 670nm red and 700nm red though so im not ready to discredit it usefulness yet.
