Lighting
As plant producers, we think of ourselves as the original green industry. Ultimately, everything we do is, or was, driven by sunlight. Photosynthesis provides energy for our plants to grow now, and millions of years ago to grow plants to become the fuels we use for heat and to power vehicles. We could argue that we’re already a truly solar-powered industry!
Research at the University of Guelph shows that stationary lighting systems are more effective for plant growth than movable pulse lighting, a new approach to supplemental lighting.
A popular resource book shows how manipulating light levels can help growers produce consistent quality plant material through the year.


Well known for their commitment  to innovation, Alberta’s Doef’s Greenhouses installed two acres of lights last year, primarily for the winter cucumber crop. The results have been encouraging.
Lighting, and its effect on plant growth, was just one of several themes among student research initiatives at U of G last semester. 
Tomatoes can now be grown in greenhouses faster and year-round, thanks to a gene identified at the University of Guelph from natural germplasm. This gene will ultimately allow growers to take advantage of increased sales from year-round production, and get higher market value for their produce in the winter months.
