Geoff Weaver, PhD student in the crop physiology lab just published a paper titled ‘A photochemistry-based method for optimising greenhouse supplemental light intensity’ in BioSystems Engineering. The paper focuses on optimization of supplemental lighting in greenhouses using physiological concepts.

• Electricity use of greenhouse lights can be reduced using dimmable LEDs.
• An optimization problem is formulated to minimize electricity use for lighting.
• The problem is solved using a quick and computationally-simple algorithm.
• Lettuce lighting requirements are simulated using typical meteorological year data.
• Annual electricity costs can be reduced by an estimated 9.55% using this method.

The paper can be downloaded for free till early June using this link:
