Evaluation of growth and nutritional value of Brassica microgreens grown under red, blue and green LEDs combinations.

Microgreens are rich functional crops with valuable nutritional elements that have health benefits when used as food supplements. Growth characterization, nutritional composition profile of 21 varieties representing five species of the Brassica genus as microgreens were assessed under light-emitting diodes (LEDs) conditions. Microgreens were grown under four different LEDs ratios (%); red:blue 80:20 and 20:80 (R :B and R :B ), or red:green:blue 70:10:20 and 20:10:70 (R :G :B and R :G :B ).
