David Llewellyn has been working in the horticulture industry for three decades. As a Research Associate at University of Guelph, his research has specialized in characterizing and optimizing the growing environment in greenhouse and indoor production systems. His aim is to serve the controlled environment horticulture industry by performing grower-relevant research that will improve crop quality and production efficiency while reducing the industry’s environmental footprint. Especially with the advent of modern horticultural LED technologies, crop lighting has become major research focus, including: intensity, spectrum, and photoperiodic manipulations. Recent scientific publications have included both indoor and greenhouse lighting studies conducted on cannabis, microgreens, and floriculture (potted and cut) commodities.
