yer i agree
but i think we have a problem how we talk about "blue" light in an led reference frame, 99 times out of 100 we are talking about a very narrow but quite intense band of blue right at 450nm. but all the surrounding "blue"nm are barely represented, massive gap at around 470,480,490nm and very little bellow 450nm you get a touch of 440 then it drops of a cliff, forget about anything around 400nm and bellow.
these missing blue nm are present in other grow lights in varying quantitys - cmh, metal hialide, t5 flourescents the sun ect...but none in standard led spectrums...we are missing a trick.
most white led diodes are based on the 450nm pump because its the most efficiant way of producing light... but im not sure its the best way for
