Effects of five LED treatments (W, WDR61, WFR30, WDR61FR30, WDR122FR60) on the growth parameters, chlorophyll content, and nitrogen concentration of basil cultivar “Emily”. In each treatment, W refers to a broad-spectrum white LED, while DR and FR denote supplemental deep red and far-red light, respectively. The numbers indicate the photon flux densities (μmol·m−2·s−1) of the added DR or FR light.
