Improvements in and relating to controlling characteristics of photosynthetic organisms

摘要

Disclosed is a light dosing system (1a) configured to direct light onto a target area (2). The light dosing system includes one or more light emitters (4) positioned above the target area (2) and a means (6) for controlling one or more characteristics of the light emitted by the light emitters (4). A conveyor (5) alters the relative positions of the light emitters (4) and the target area (2) and a lighting controller (13) reads a media having a predefined dosage regime stored thereon. The lighting controller (13) alters one or more characteristics of the light emitted by the, or each, of the one or more light emitters (4) onto the target area (2) in accordance with the predefined dosage regime.
