PHOTONIC ENGINE SYSTEM FOR ACTUATING THE PHOTOSYNTHETIC ELECTRON TRANSPORT CHAIN
FIG5 is a graph showing amount of light absorbed by chlorophyll A, chlorophyll B and Carotenoids over a range of wavelengths
In general, most plants contain either Chlorophyll A, Chlorophyll B or Carotenoids, or some combination of the three. Specifically, Chlorophyll A, Chlorophyll B and Carotenoids are pigments responsible for photosynthesis within plants. FIG5 shows an exemplary plot 100 of light absorbed by Chlorophyll A, Chlorophyll B and Carotenoids, as a function of wavelength as shown in curves 105 (Chlorophyll A), 110 (Chlorophyll B) and 115 (Carotenoids).

['1. A horticulture system for growing plants under artificial lighting in an environment, the system comprising: at least one lighting device, the at least one lighting device having a first lighting element (32a) configured to emit light at a wavelength that is within 20 nanometers of a peak absorption of a pigment of a plant (14) positioned in spaced relation to the at least one lighting device to receive light emitted by the at least one lighting device, characterized in that the horticultural system is configured such that light from the first lighting element is pulsed with emission during first, second and third lighting intervals with a first dark interval provided between the first and second lighting intervals and a second dark interval provided between the second and third lighting intervals; and the horticulture system further comprises at least one further lighting element configured to emit a background light with an intensity lower than an intensity of the light emitted by the first lighting element during the first, second and third lighting interval.']
