N2 - Many ornamental crops need a certain number of hours of light to bloom. With a higher daily light integral (DLI), this number decreases in various genera of bedding plants and perennials. However, this is not universally applicable. The DLI also affects sensitivity to the spectrum. At a low DLI, blue inhibits stem elongation. At a higher DLI, this happens much less. Furthermore, the temperature sum and light integral must be in balance for plants to flower at the desired time.
