Lettuce cultivation in hydroponic systems using the Nutrient Film Technique (NFT) is widely practiced globally, and it can be done under either natural light or LED light conditions. LED lights are commonly employed in plant factories or as supplemental lighting during periods of insufficient natural light, such as the winter season. To achieve optimal growth and quality of vegetables grown in NFT system, various factors need to be considered, including temperature, light intensity, humidity, and others. Our study aimed to investigate the yield and mineral content of lettuce cultivars grown under natural light and LED light conditions. The experiment was conducted at a greenhouse in USAMV. We observed that lettuce cultivated under natural light conditions exhibited higher fresh weight, dry matter, phosphorus, iron, and copper content. Conversely, lettuce grown under LED light conditions showed higher nitrate, potassium, calcium, magnesium, and zinc levels.
