Dr. Barry Micallef, University of Guelph
The topic: Strategies for Extending the Greenhouse Vegetable Growing Season in Ontario
The talk: Dr. Micallef’s lab has obtained much evidence showing that the poor response of greenhouse vegetables to supplemental lighting is linked to altered patterns of nitrate uptake during specific periods of the day under long photoperiods. A new time-of-day fertigation strategy will be presented that shows promise for improving the response of greenhouse vegetables to supplemental lighting, and some related research on low light tolerance will be discussed.

David Arkell, president and CEO of 360 Energy Inc.
The topic: Common Energy Saving Tips and Techniques
The talk: This presentation will cover common processes and technical solutions that can be used by greenhouses to help reduce energy consumption and lower energy costs. While most businesses recognize that energy is an significant cost, it is typically seen as either a fixed cost that cannot be helped, or a fixed cost that requires a large capital investment for it to be reduced. In fact, there are many ways that greenhouses can save money and energy through little to no capital investment.
