Original Abstract
LED arrays emitting at 720nm activated chlorophyll f-based photosynthesis in lettuce, extending usable light spectrum by 15%. Combined with standard PAR LEDs, total biomass increased 28% with only 8% more energy input. Results demonstrate the commercial potential of far-red supplementation in controlled environments.

Species Mentioned
Lettuce is an annual plant of the family Asteraceae mostly grown as a leaf vegetable. The leaves are most often used raw in green salads, although lettuce is also seen in other kinds of food, such as sandwiches, wraps and soups; it can also be grilled. Its stem and seeds are sometimes used; celtu...
