It's not that the MCCree curve is wrong, it has been confirmed, with minor deviations, especially in the blue range... for many crops in recent more advanced measurements. However, RQE of a leaf does not provide a complete picture,
not even close. It also doesn't support 3500k, not at all.
You are so far off base with this comment that it is not even funny...
That sums up the entire dutch grow forum nowadays quite well... so far off base, it's not even funny. And me 'knows' he hasn't done enough growing, still trying to initiate flowering with P lol... Just one of the first who used cobs in the dutch forum, so people ask him questions, which made him believe he actually has the answers too. Classic one-eyed king scenario.
The Chlorophyl chart is in their datasheet ..... so ... ehm .... yeah I connected that "dot".
If only something would actually go to your head. Ah well, it's good to see you finally made the step from COB bashing to trying it for yourself. Now if you have some actual experience under your belt, perhaps you'll understand that spectrum means very little and photons are king.
McCree obviously also shows that blue and red are most readily used by the plants since chlorophyl is responsible for the bulk of the photosynthesis, so indeed it makes sense in a greenhouse to supplement with that. Moving a much lower red peak by a few Nm to the longer end of the spectrum is not going to overcome a huge deficit in quantum yield from CRI90.
Yeah, that sums me up so well lol...
Fucking delusional you are with your "experience under your belt" while growing with neither 2700k or 3500k... I've been growing a lot longer than you have kid. Touching a cob won't change its output or change what is an obvious more optimal spectrum. The "huge deficit" is not in the cri90 but in your level of intellectual honesty. Once something has gone to your head it will get stuck there forever, I've seen that over and over in the dutch forums. Like your true NFT nonsense... Problem is the same as usual, what you think you know isn't actually so. It's only what you wish to be true. Repeating your conjecture isn't going to make it any more accurate. The dog you have in this fight is that you just don't want to realize you're not all-knowing. That's just messed up, unlike Rhaz you are not even making money being so goddamn ignorant.
And I'm not "trying" cobs fool. That comment alone shows you are missing more than a few points. I never bashed high cri warm cobs either. I think you would get along well with Churchhaze, similar simplistic strawman logic.
"photons are king"... unfortunately for you it's not that simple. There's no black-and-white choice between spectrum and intensity, that's just bibled nonsense you are parroting. An artifact from people here trying to beat hps, like 3500K itself.
You guys just keep talking nonsense and shit and cherrypicking charts... pretending you understand shit about plants... will make 2700K 90 CRI (with a little extra red) harvest time even more enjoyable.
