This review synthesized recent literature on the application of LED lighting (2012–2025) and other key environmental factors (2017–2025) in lettuce cultivation under controlled environments. The effects of LED light intensity, spectral quality, photoperiod, and light direction were critically evaluated alongside temperature, relative humidity, CO2 concentration, and air velocity.
