Managing Nighttime Greenhouse Light Emissions
Author: Ontario Ministry of Agriculture, Food, and Rural Affairs (OMAFRA)
An increase in the use of supplemental lighting in greenhouses has been accompanied with an increase in the amount of light emitted from greenhouses at night during fall and winter months. Without proper management strategies, light emitted from greenhouses during nighttime hours can potentially be disruptive to neighbouring residents. As a result, the objective of this document is to outline the latest research in greenhouse light management for producers and to provide information on managing nuisance complaints should they arise.Continue reading “Managing Nighttime Greenhouse Light Emissions”
