Abstract
A horticultural system having lighting elements pulsed with an off time proportional to the turnover time of the photosynthetic electron transport chain of a plant. The lighting elements emit light at a wavelength within 20 nanometers (nm) of a peak absorption of the pigment of the plant and are controlled to provide light at predetermined intervals as needed by the plant cause photosynthesis and reduce excess unproductive light.
Claims12
A horticultural system for growing a plant under artificial lighting comprising:
- a lighting element positioned in spaced relation to a plant to emit a light onto the plant;
- said light comprising wavelengths that are within 20 nanometers (nm) of a peak absorption of a pigment of the plant;
- wherein said light from the lighting element is pulsed to provide predetermined intervals of light;
- said predetermined intervals of light comprising light that is evenly pulsed.
1 more element
A horticultural system for growing a plant under artificial lighting comprising:
- a first lighting element positioned in spaced relation to a plant to emit a first light onto the plant;
- said first light comprising wavelengths that are within 20 nanometers (nm) of a peak absorption of a pigment of the plant;
- a second lighting element positioned in spaced relation to a plant to emit a second light onto the plant;
- said second light comprising wavelengths that are within 20 nm of a peak absorption of a pigment of the plant;
- wherein the first light and the second light from the first lighting element and second lighting element are pulsed to provide predetermined intervals of light with an off time proportional to a turnover time of a photosynthetic electron transport chain;
- and
- wherein the first light has a greater radiometric intensity than the second light.
