Dose-response of tomato fruit yield to far-red fraction in supplementary lighting

Supplementary LED lighting in greenhouse horticulture is typically rich in red light (R, 600 – 700 nm) while it lacks far-red light (FR, 700 – 800 nm), resulting in growing conditions with lower-than-solar far-red fractions (< 0.46; FR / (R + FR)). In these light environments, the addition of FR can…Original Article
