Table 1.
Representative ratios of blue, green and red fluxes as a percentage of photosynthetic photon flux density (PPFD). Values from the three species and two intensities deviated less than 10% from the average and thus we present average values. RB refers to treatments comprised of red and blue LEDs and RBG refers to treatments comprised of red, blue and green LEDs.
