It isn't funny but your comment sure makes it seem funny Lmao
Yes sometimes the difference between tragedy and comedy is a very thin line... or more like a grey area. Seeing several people blindly pick 1750ma drivers because wietefras decided that is best to do is funny but sad at the same time.
Riu is usually more entertaining. Like Jorge arguing pro-high blue because he read blue affects stomata regulation. That just cracks me up. Or even better, Rahz posting about morphology. Search the forums for user
@Rahz and search term "morphology", note the dates, then do the same for my username. Slapstick comical. It's a level below the level of P is flowering so more P is more flower...
Or how about gg referring to info from Heliospectra above who provide similar general indoor spectra like osram, philips, and like cree suggested.
the obvious way to go about indoor growing for any horticulturist (WR or WBR) unless one has a specific scientifically proven extra-ordinary best cannabis spectrum. Doesn't look much like cree 3500k 80cri to me.
I think its more a photon vs spectrum camp.
Funny fact the members of the photon camp have allot of real time hard data to present. Data about Weed!
While the spectrum camp is still figuring out what spectrum to choose and have allot of theory data. About tomato and Cucumis sativus(cucumber)
That's all just what the 3500k-datasheet-efficiency camp die-hards and some people projecting the illusion of knowledge want others to believe. Spectrum does not dictate photon output. High and efficient input and more optimal spectrum are not mutually exclusive. Rahz's commercial lights are not more efficient than my light is, neither is wietefras' setup of 3000k at 1750...
Apparently, you can have both and cooler 80 cri cobs won't make them more efficient by default. Apparently, they rather sacrifice spectrum to pretend that is efficient instead of at most economical, but then they don't buy the cheapest cobs either... They don't run maximum efficiency, they don't run maximum intensity, they don't endlessly wait for the next more efficient led. All their nonsense in this discussion is just one big fallacy. Letting efficiency dictate spectrum while it is influenced to a much larger extend by other factors is just foolish.
You know what else exists in theory? Gravity. Just like the influence of blue light on auxins and indirectly ethylene and thus flower production it's quite real in practice too. Same for anthocyanin production, blue being great to induce photoinhibition, green resulting in shade avoidance like FR but without the advantage of FR... which too goes further than what some self-proclaimed experts here read about emerson effect. Fyi most plants operate very much in the same way in many aspects, in theory and in practice...It's ironically the 3500k camp that cherrypicks specific spectrum theory to get to their numbers, claiming to know what's best for cannabis, while ignoring and defying all the other botany that would show how silly they are. Which doesn't even conflict with mccree curves, just with their own biased conclusion. In practice, there's just a lot more to it.
