This study aimed to evaluate the effect of four light intensities (90, 140, 190 and 240 μmol m-2 s-1) provided by red-blue LED light (spectrum ratio: R660/B450 = 4/1) on the growth and quality of hydroponic cultivated spinach. The results showed that when the light intensity increased, plant height,...
