What would you say to one that is the same spectrum and had switches for the different spectra?
You could then add or remove different nm however you wanted for a customized spectrum for whatever stage you are in.

Of course spectrum makes a difference, Hortilux has made a fortune from selling high price bulbs with very little added blue in HPS.
However, we have been through the monowave emitters years ago. The discreet mono emitters make a spectrum of a series of spikes, not a full white light, like the light all plants evolved in.
Been using most all white LEDs and COBs for years and have HPS CMH and Lumigrow and Magnum and a 300w Vipar and more under the house now.

No, not that crazy at all. Certainly spectrum has the potential to double yields . . . if you start from a low base (such as growing under blue monos, for example, if you want to get extreme).
Someone I know once compared growing to racing cars. It's the little bits that all add up that make you go faster. One small change on its own may be worth only an incremental improvement, but once you combine all the parts, it starts to add up.
I don't think we should ignore spectrum. Nor do I think we should place more importance on it than it deserves. But if there's something to learn from this experiment, then maybe we should keep our minds open?
I do find it interesting that the HLG white light is supplemented by red monos, so the RGB train - or at least the mono train - may be less of a wreck waiting to happen than another form of transport waiting to improve. It comes down to efficiencies of scale: if red light works, and there's a more efficient way to produce it (monos) then they have their place - as do other colours (UV, Far Red anyone?).
Likewise, we can also learn what to avoid. Maybe that extra stretch isn't so desirable? Maybe we can all make up our minds once the grow is finished.

That's what made me pay $200 for a viparspectra light when I first started :/

I'd argue that hype is what made you pay $200.
It‘s already available, from cutter, all the flavors you want...

Nah I legit didn't even know about weed growing sites or any grow lights, I knew street lamps could Grow plants though

My old A51 75w R/W and SGS 160 have white and red diodes. Sometimes I use those with just white diodes on. Cree did not make deep red diodes back then and these are about 620nm if memory works. Everything else is white 3500k to 4500k mostly.
But just red, no supplemental blue diodes, or green.
It was also difficult to get COBs under 3500k back then. Newest is 3 years old.

Nice to see you posting in here Prawn Connery. There is still a voice of reason and scientific curiosity left on RIUNo, not that crazy at all.

I do believe you’re correct, 620-630nm
I have one too. CREE XPE reds
Whites should be 4000K XPG

Before de-fo.
Yes they are hungry but simply feeding them hasnt done the trick yet so phase 2.

My white listed are 4500k on the SGS, 5250k on R/W75, 4000k Vero 29 on W90 and3750 on XGS 190. Have at least 1 and usually a couple discreet panels remain idle.
Will update sometime but all are the next best thing to the latest.
