LED Light Types, Kelvin Rating, and Color

[MacGyverStoner]

So, why the perceived color difference? Why is mine with twice the watts growing the same?

I’m not entirely sure what you are asking. In an thread from a couple of years ago, I address why some white light in LEDs can be good and why Red and Blue LEDs are more efficient at growing than only or all white LEDs, watt per watt.

Experience with LED marijuana grow lights?

Some other things to think about, in the video he is using a 25% blue to red ratio. 1 blue 450 nm light and 3 red 650 nm is obviously 25%. However as I said, red is more efficient or “productive” if you will, and you only need a minimum of 20% 450 nm blue, 1 blue to 4 red would work, then you could arrange the blue in the center of the 4 red in a pattern similar to the number 5 side of a pair of dice, for even distribution of both spectra. Then add groups of 5,000 K to 6,500 K full spectrum LED…

Have a read and maybe it will answer some of your questions, or maybe help you clarify your own ideas on the matter and you will come up with new questions, which I’d be happy to answer as you reply here.

happy growing,
