Shoot FW and DW (A,D), root FW and DW (B,E), and shoot/root ratio FW and DW (C,F) of M. crystallinum grown under different combinations of red- and blue-LED lightings for 21 days. Values are means ± standard errors. Means with different letters are statistically different (P < 0.05; n = 6) as determined by Tukey’s multiple comparison test.
