 light for Cubes Cooldaylight VS Blue 460nm

In led technology what is better?
Cooldaylight 6000>K
or
blue 465nm

By Albert Hofmann :
Been cautious man, I though I would start with a smallest, smallest quantity. Namely I started with 0.25mg.....and my intention was to increase dosage to see if something will happened.
That very small dosage, the first dose of my experiments i planed, was very very strong.

Closest to full spectrum has shown best results across all species. There has been extensive tests by members here.
Aim for your 6000K.

Nothing personal but that's old news. 6000k to 7500k i used that, and it show nice results but I'm interested in that peaks 370, 440, and 460 nm.
Did someone come to conclusion what is better blue or cool white?
And is maybe both needed for best performance?

No sense in asking 6000K was worthwhile if according to you its "old news".
You might want to take a look at all the threads in the bottom of the page, your answer lies within there (specifically blue nm). They go back as far as 2000.

A very specific color would have a very specific wavelength.
In other words Kelvins is how hot it is .... i.e. blue daylight......
Nanometers is amount of waves per second that the light.
according to Wien's law, you take 3,000,000 / The # of Kelvin & get the Nanometers.
So,
3,000,000 / 6500 =
461.53 Nanometers which is what you are looking for 
Just get a shop floro bro its the same!
*This is also the same reason you need to wear one of those masks to weld shit with.
Really not advanced mycology.
Pretty simple physics actually.

Hi Hofmann1943; The whole 370, 440, and 460 nm light spectrum thing comes from E.R. Badham's Master's thesis that Paul Stamets uses in his “The Mushroom Cultivator” for the basic growth parameters of Psilocybe Cubensis. This has never been proven true with growing mushrooms by academic peer testing so it has become an anecdotal thing with many people. I would go with 6500k to 7500 Kelvin light spectrum white LEDs if you want to go with LEDs.
White light LEDs uses an UV emitter that pumps mixed phosphors much like a florescent tube uses with the UV emission from a mercury arc to pump its phosphor. The trouble they are having with white LEDs and its color rendering has been developing phosphors that have a high enough efficiency when pumped by the long wave UV that LEDs are capable of producing. What we have is mostly red and blue phosphors to use in white LEDs so it’s like the olden days when I was a kid (YOB 51) and you only had warm white or cool white tubes (today some of the reptile lights use up to five phosphors). There is great interest in developing a yellow/cyan phosphor that would help when used with the other phosphors to yield better color rendering with white LEDs for uses in back lighting LC displays like big screen TVs, ex.
The cheapest and simplest way to go is with 6500K florescent lighting. I hope this is of some help; Chee Wiz

No.
The blue you want is 460nm. You want the higher wavelength if possible.

Hi caradoc; I have already give the argument against putting too much stock in these old papers in another post. See: http://www.shroomery.org/forums/showflat.php/Number/13355429
Any thing that is based on simple observation that's not tested is anecdotal evidence. What we have been exposed to as being true has away in how we interrupt anecdotal evidence and this is exactly why we need to test it. In the end it's the peer review testing that will prove if it holds water or not to use a common term.

Well did someone on this forum test it?
If someone did please share your LED wisdom whit us 
I really think there is something with that blue led, and i'm willing to test it.

Hi; to the best of my knowledge no one has tested this. I have done work with night blooming plants that can be a bit hard to get to bloom at times. I've found that it does work with many plants but it takes two fluorescent tubes from Hagen (5%UV reptile & ocean water blue. This seems to work with P. Cubes but would be anecdotal proof again as I have never created a model to test it.

FUNGI ARE NOT IN THE PLANT KINGDOM
Hi; I think all of us know that little bit of truth already. So let us not digress, the spread of light energy that helps stimulate blooming in some plants is every close to the 370, 440, and 460 nm put out by Badham. So much so that I have to ask myself if Badham had taken this from botany.
Taken the fact that moon light is sun light that's reflected off the moon and is band-pass filtered because of the refraction cosed by this. It's heavily weight to the blue side having lost much of of the red going into yellow and most all of the short wave UV energy found in sun light.
It's a bit of a syllogism on Badham part that's playing on mushrooms growing during the night and moon light is found at night therefore you need moon light or simulated moon light in the 370, 440, and 460 nm spectrum to get mushrooms to grow.
I know some one that grows in an old freezer that's set up like a fully automated Marta with no lighting but for when the door is open and he gets flushes of mushrooms. I already have the lighting and have used it with growing mushrooms and feel it does help. But this could be just wishful thinking on my part because of my exposure to Badham papers in the early 80's when few would question his work and my knowledge is anecdotal at best.
I feel that RR is right for the most part in using 6500k day lighting. If some one was to ask me what lighting to buy knowing that they are starting new I would tell them to buy 6500K tri-phosphor high rendering index fluorescent Lighting (6500K Day Light) at this time. In time they will come out with 6500K tri-phosphor high rendering index white LEDs. I hope this has been of some help, the end; Chee Wiz

Yes that what i think. At least you can see your grow without any additional light.
Soooooo i'm thinking of trying this led 5500-6000K
and additional black light blue for lower wavelength like 370, 440.

Agreed. It's old news.
Those so-called 'peaks' at 460nm, etc., were wrong thirty years ago(concerning mushrooms, not plants) and they still are. Mushrooms benefit more from full spectrum daylight color than any single wavelength.
