Longer photoperiods with the same DLI increase plant growth and photosynthesis

Research Updates

• Simulated improvements in lettuce light use efficiency by extending the photoperiod
• Influence of far-red intensity during the seedling stage of hydroponic lettuce
• Lighting strategy based on sunlight prediction reduces supplemental lighting
• Far-red light increases early light interception and final yield of lettuce
• Researchers should better report key light ratios used during their plant lighting experiments
