Yes I am saying that, at its most generic level as a red, 680 and the PSII should be the base building block. With respect to species you cannot ignore the eco history of plants and how they have evolved/hybridised. Plants from a tropical or arid history have differing stories with respect to...

I think its an interesting spectral juxtapostion, it resolves for lower eff of 730, you dont seem to get Pr to Pfr as sweet as 660, but does not get back conversion causing elongation, and you right it gets em stinky. I think its the goto red. Cant speak to performance when blended with UV but...

We have a tool we use internally for grow space design, decided to put on line for community use for those who still like to build. Its a PPFD Simulator, may be of interest to the tinkerers and searchers https://www.cutter.com.au/visualise-3030c-leds/

I only saw it on one of the comments by GML on his vid, I cant see a problem, reviewing a light take time and cost, but money = bias, sure Kim K dont push new lolly water for no money.

I think the answer is pretty simple, however I dont want mods all over me, I understand RIU is a business so cant promote such an option here. I will make the observation that these have a Samsung footprint so improves it chances, however given the fascination with even low eff parts like 281B...

Epistar are really a die manuf, package manufacturers buy their die and then sell as 'EPISTAR' leds. Epi do make nice RED die, however there is a world of difference between Power RED and 2835 Red, and this speaks to the general dumming down of grow panels, china copied the Quantum and over time...
