i dont think that has been proven to be true.some say higher par equals faster growth.some say higher kelvin equals better color.i think water quality is the most important factor for growth and color.but some very low par bulbs seem to produce a more spindally growth in sps .i have not seen an appreciable difference between 12 k and 10 k reeflux bulbs in color or growth
