A light harvester or collector collects solar radiation from an unshaded location adjacent a growing plant. The light harvester can be either imaging (e.g., parabolic reflectors) or non-imaging (e.g., compound parabolic concentrator). The concentrated solar radiation is projected into a light transmitter that conducts the light through the plant's outer canopy and into the inner canopy to a diffuser which disperses and reradiates the light into the inner canopy. The diffused light transforms a non-productive, potentially leafless zone of the plant into a productive zone so that more fruit can be produced per volume of land surface. The system can prevent transmission of infrared into the inner canopy so that the inner canopy zone is not heated and the amount of water lost to transpiration is reduced. The system can also modify other spectral components to affect plant development and to control pests and diseases.
