“…151 A normal light intensity gets radiated or reflected in protected cultivation, vertical farming, and closed systems for soilless farming, but a high intensity of light reflects in open systems, soil affected regions, and stress areas in soilless farming. 152 Light intensity is the basis of and essential for photosynthesis, respiration, flowering stimulus, phytochrome enzymatic metabolism, plant growth hormone regulation, stress regulation, and gene regulation in crops for creating assimilatory products. 153 Agricultural and horticultural crops require distinct light duration (hours) per day for regulation of growth and physiological processes in open systems, closed systems, protected cultivation, vertical farming, soil affected areas, stress areas, and prone areas.…”
