I would ignore that debacco guy. I don't see people growing with enough blue since blurples got "cash for clunkered" (convinced someone demonized then bought up all those good blurple spectrums). Everyone is under 3-3500K led which suck and don't let the plant transpire, so..
Heat isn't the issue. Most white leds lack usable red. Heat is a bandaid to get P flowing because it falls on the IR spectrum, but much higher than 630-830 which the plant actually wants.

17% 660 diodes. With 5K chips for blue. Next year's model will have even less white/green/yellow and dedicated 460nm. One step closer to acceptable. Closer to blurple lol.
Waiting on science? Yeah, that's why Oak Island had a billion episodes lol. Fuck the led industry. The first brand to put a decent spectrum out with a veg/bloom switch must have been threatened by the led mafia. There's no reason for all these useless 3000K lights with no red and no blue.
