Spectral distribution characteristics of white, red (R) and far red (FR) LEDs used for night break (NB) and different R:FR treatments. The black curve represent white LED light; the two red curves represent two R light intensity, 10 and 50 μmol·m− 2·s− 1; and the two blue curves represent supplemental FR light to make R:FR values were1.2 and 0.6
