Abstract:This research aimed to investigate the effects of light intensity and the carbon dioxide (CO2) concentration on spinach’s growth during vegetative stage in plant factory (PF). Two experiments were conducted with different CO2 concentration in closed chamber (500 ppm and 800 ppm). In each experiment, plants were hydroponically grown under three light intensities of 115, 140 and 160 µmol.m-2s-1. Growth’s parameters were determined at different growth stages (T30, T37 and T44 respectively to 30, 37 and 44 days af… Show more
