Basil, cilantro, and sage seedlings grown under sole-source lighting with different blue (B; 400 to 499 nm), red (R; 600 to 699 nm), and far-red (FR; 700 to 750 nm) photon flux densities (PFDs), whereas values represent the photon flux density (in µmol·m−2·s−1) of B and FR wavebands.
Blue light and far-red radiation interact, sometimes in contrasting ways across species, to regulate stem length, leaf area, and biomass accumulation.
