what effect if any would a yellow bug light have on my grow? I know for bugs great but is it a useful light in growing? i dont know what spectrum it is but found this online "The yellow pigment used to coat the GE Bug Light, filters out any light below 490 nanometers making the light it transmits non-existent to insects" what does 490 nanometers mean? someone got that light graph or something?
