- Page 3 Red and Far Red Light Plants sense the amount of light in the ranges around 660 na- nometers (red) and 730 nanometers (far red), and use the ratio between the two to direct growth. Though plants differ in the details of their reaction, in general a low Red / Far Red ratio results in elongation and lower leaf area compared to a higher ratio.
