Abstract: Methods and systems for using UVI data in plant evaluation applications avail themselves of the correlation between PAR and UVI to estimate PAR based on UVI and apply the PAR estimate in a plant evaluation application, such as a plant selection or plant heath diagnostics application. A UVI-based PAR estimate may be used, for example, to dramatically reduce the time that an environmental probe must be deployed at a plant site by normalizing a sensor-based PAR estimate generated from short-term measurements taken by the environmental probe to produce a faster, more accurate and more reliable plant evaluation.

Abstract: Photobioreactors and systems for growth of a photosynthetic organism are provided herein. The systems and photobioreactors can comprise features and modifications in order to improve photosynthetic growth efficiency and light energy utilization. Also provided are methods and systems to improve the cost-effectiveness of a photobioreactor system for growth of a photosynthetic organism.
