Optimizing Light Use Efficiency and Quality of Indoor Organically Grown Leafy Greens by Using Different Lighting Strategies

“…Each tray was filled with 800 g of an organic peat-based substrate (Premier Tech, Rivière-du-Loup, QC, Canada) enriched with compost, pelleted poultry manure, feather meal, and potassium sulphate to fulfill the fertilization needs of the species studied, according to the Biogreenhouse Guide Research [27]. Based on the specific leafy green species and previous experiments [28], two levels of organic fertilization were selected: the 100% level (14.1 g N m −2 , 1.9 g P m −2 , 9.8 g K m −2 , 9.0 g Ca m −2 , and 1.3 g Mg m −2 ) for the lettuce cultivars, shiso, chicory, and basil, and the 150% level (21.1 g N m −2 , 2.9 g P m −2 , 14.8 g K m −2 , 13.6 g Ca m −2 , and 2.0 g Mg m −2 ) for the other species. Two harvests were conducted, with the initial harvest occurring on the 21st day after sowing (DAS) for early-growing species like spinach, Swiss chard, lettuce cv.…”
