De Cloet delivers structures for Guelph tunnel research

In a 3-year research project at the University of Guelph, High tunnels (and their associated technologies) will be evaluated against traditional field production for season extension & increasing profits for organic production of high-value organic crops (e.g. bitter melon, tomato, pea shoots & pods etc.).

Specific objectives are:

1. Select, evaluate and develop protocols for using high tunnel technologies in harsh Canadian climates including:
a) screens to reduce insect and pathogen pressures
b) shading materials to reduce and diffuse high-intensity, direct light
during summer months,
c) plastic mulch (different colors) and drip tape to reduce weed pressure
and improve nutrient and water use efficiency;
2. Investigate microclimate conditions at different seasons under high tunnels;
3. Determine cost-benefit of using high tunnels in Canadian climates.


A multidisciplary research team is involved in this research project:
  • Dr. Youbin Zheng: Greenhouse organic crop production, plant nutrition Mr. Dave Llewellyn: High tunnel infrastructure and plant production Dr. Yun Kong: Vegetable production under controlled environments
  • Dr. Rene Van Acker: Weeds management
  • Dr. Ralph Martin: Sustainable food production
  • Dr. Mary Ruth McDonald: Integrated vegetable crop management Dr. W. David Lubitz: Engineering, microclimate
  • Ms. Martha Gay Scroggins: GCUOF co-ordinator
  • Mr. Evan Elford: New Crop Development Specialist (OMAFRA)

Six high tunnels are installed at the Guelph Centre for Urban Organic farming (GCUOF).

This project is supported by Agriculture and Agri-Food Canada’s Organic Cluster Research Program and managed by Organic Agriculture Centre of Canada. They thank De Cloet Greenhouse Manufacturing Ltd. for adapting their commercial tunnel technology to a research application & ongoing technical support.
