Influence of Artificial Lighting on Plant Growth in Hydroponic Environments

Hydroponics, a soil-less technique of growing plants using nutrient-rich water, is revolutionizing modern agricultural ways for maximizing production per unit area. However, one of the vital challenges that lies inside hydroponic farming is the effective use of synthetic developed lighting fixtures, as the farming is majorly done indoors and in polyhouses environments. The present review explores the significance of lighting on crop dynamics and modern lighting technologies present with the growers. LEDs, fluorescent lamps, high-pressure sodium (HPS) lighting and rising technologies like plasma and induction lighting impart significant effects on plant growth, yield and nutrient uptake. The review also examines the key elements which include light spectrum, depth, and photoperiod, which have a direct impact on photosynthesis and photo-morphogenesis. The paper also highlights the significance of balancing red, blue and inexperienced wavelengths to optimize the plant morphology, biomass accumulation and even biochemical composition. Information on how various lighting conditions alter plant development and physiological responses, and therefore, growers can tune their systems accordingly for fetching maximum yield under hydroponic cultivation. This study emphasizes on importance of smart lighting techniques for enhancing not only crop production but also energy conservation and environmental sustainability.
