I'm demonstrating the fact that an LED light with a high PAR rating doesn't mean it's a better grow light than a larger HPS with a lower PAR rating. That SHOULD indicate that PAR isn't as meaningful as you want to believe but you refuse to see it because you don't want to (or can't) admit that what you thought you knew is wrong and that somebody without a degree in botany is right.
Now you're trying to move the goal post. We're not talking about what LED lights might be one day, we're talking about what they are now. Even NOW, some smaller LED lights have a higher PAR reading than some larger HID lights but that doesn't mean jack.
Regardless, plants do USE UV even though you claimed they don't. Are you also saying that chlorophyll a doesn't use UV below 400nm? I'll tell you right now that it does, just not as much as some of the other spectra. BTW, CLW suggests UVB for the last 2-4 weeks, IIRC. Also cannabis trichomes are a form of protection from some insects too.
I'd like to teach you logic but I'm only human...
Hilarious...

And also to clarify, I CAN legally grow cannabis in my lovely state of Colorado...........
