All Season Greenhouses

NOPRI is designing and building low-cost, energy efficient greenhouses for season extension and winter production in Northern Ontario.

Traditional glass or plastic film greenhouses are poorly insulated and typically heated in the cold seasons with fossil fuels at great expense. Modern technologies such as multi-wall polycarbonate glazing, in-ground thermal batteries, styrofoam insulation, and LED lighting can make greenhouses much more efficient, but are too expensive for large-scale adoption by agriculture. NOPRI is developing efficient AND cost effective winter greenhouses using innovative designs and material recycling.

Our goal is to enable local production of fresh food throughout all of Canada’s seasons – an achievement which would benefit food security and the environment. We also believe that local food production can nurture community resilience and health through better nutrition, enjoyment of gardening, and education.

We have constructed a prototype 100 square foot greenhouse optimized for the homestead scale. Next summer (2017) we will build a 1000 square foot small-scale production greenhouse. With knowledge gained from these projects we will pursue construction of community greenhouses in partnership with local municipalities.
