Why no blue light in some LEDs?

Considering this budget one to add to my arsenal, but I think I'm not understanding why there's no blue light listed as part of their spectrum; isn't that a necessity for chlorophyll formation? https://www.viparspectra.com/products/xs-series-xs2000

I never recommend YouTube except to recommend Dr Bruce Bugbee. Not a pseudonym and an actual expert on hemp and light spectrum. An actual professor at Utah State University. Watch his first ones. I did after I got a batch of seedlings bleached whiter than ivory. Under a 105 watt little Bestva. Used the information to buy my large bar style LED.

The switchable blue 450Nm added on many newer quantum boards is just one of the recent 'improvements' but as mentioned above, the 5000K white light in the Vipar is considered more blue and the 3000k more red. Using 3000k + 5000k in equal basically equates to 4000k.

The 450 blue is said to be able to control stretch and penetrates deeper into the leaf than white light

The majority of old blurples used 470Nm blues and 630Nm reds. Mainly due to price, infomation and technology.

The 450 royal blues are the next step up from the voilet UVa's on the visible light spectrum. Not good for the eyes!

One can only imagine the precise growth control that may be available, with the next evolution of grow light tech. Light emitting diodes are ancient techology really. Only so much further to take it.

It seems inevitable that the majority of the 1st worlds food crops will grown indoors either under artificial light or with highly sophisticated enviroment filters/systems within the next 50-100 years. Led's will soon be replaced by even better tech. Plasma re-invented, Lasers?

No, i will not make out with you. You got Chlorophyll Man up there talking about God knows what and all you can talk about is making out with me? I'm here to learn, everybody, not to make out with you. Go on with the chlorophyll.
