A spectrum of light with wavelengths between 700 and 800 nanometers, which is slightly beyond visible red light. In cannabis cultivation, far red light is used to influence the photoperiod and growth cycle of plants, particularly by accelerating the transition between growth phases. Far red light can encourage stem elongation, faster flowering onset, and increased yield potential, making it a valuable tool in controlled growing environments.
