Lighting systems for providing supplemental light to plants to facilitate plant growth and/or to provide supplemental lighting in situations where sunlight is insufficient. Lighting systems may use LED technology to deliver specific wavelengths of light to maximize utilization of the supplemental light for photosynthesis. By delivering light having one or more specific wavelengths, it is possible to use a light that consumes relatively little power (e.g., about 10 watts or less) while providing sufficient supplemental light to facilitate healthy plant growth. Lighting systems may include a light-sensor to facilitate control of the amount of light provided. For example, a light-sensor may be used to automatically adjust the amount (e.g., intensity or duration) of light provided when the amount of ambient light available to the plant dips below a predetermined level. |
