Does supplemental lighting make sense for my crop?-empirical evaluations

Supplemental lighting is recommended when the DLI inside the greenhouse is not meeting the anecdotal cropspecific minimum DLI (typically 10-12 mol m-2 d-1). For example, a greenhouse with DLI of 8 mol m-2 d-1 requires 4 more moles DLI by supplemental lighting to meet the minimum recommendation for tomato of 12 mol m-2 d-1 (Dorais, 2004). However, while growers can assure acceptable production levels under these DLI, a question of whether use of electrical lighting (LEDs, HPS, etc.) can generate…
