High-Performance Greenhouse Complex

Université Laval, Québec, Québec
What the facility does

Greenhouse growing, irrigation, sustainable development, confinement, biopesticides

Areas of expertise

The high-performance greenhouse complex is a reference in terms of research infrastructure. Its facilities are among the most sophisticated in Canada and North America. Recognized for their energy efficiency, they enable highly precise, automated control of the greenhouse climate and considerably reduce environmental emissions. The infrastructure contributes to cutting-edge research in the fields of greenhouse production (cropping systems and greenhouse environments, peat growing substrates, phytoprotection, agri-environment), genomics (tree genomics and forest pathogen genomics) and biotechnology (plant biotechnology and crop genomics). The confinement greenhouses enable Plant Pest Containment Level 2 (PPC-2) tests. The greenhouses and related equipment are used by both university and private researchers.

Research services

Greenhouse growing tests (market-garden and ornamental plants), phytoprotection tests, development of sustainable development technology, development of new horticultural products.
