| Abstract | This study aimed to investigate the effects of light duration on the growth of butterhead lettuce (Lactuca sativa var. capitata) cultivated in a three-tier vertical hydroponic system. A total of 131 plants were grown: 47 in the first tier and 42 each in the second and third tiers, over a 74-day cultivation period including the seedling stage. The first and second tiers received 12 h of artificial light daily, while the third tier initially received 10 h, later increased to 12–14 h to correct leaf elongation. Environmental factors such as light intensity (105–126 lux), nutrient temperature (22–25 °C), relative humidity (64–81%), pH (6.8–7.5), and EC (1.0–1.15 mS/cm) were continuously monitored. Results showed that longer light exposure enhanced plant growth in terms of leaf number, leaf size, plant height, and overall biomass. |
