It's great to see how physical activity is used alongside traditional forms of therapy like talking to a counsellor. Also, kudos for finding a way to continue growing things in the cold Calgary winters!
Don’t the polytunnel and the passive solar greenhouse serve the same purpose? Tomatoes grow well in both. Market gardeners find polytunnel tomatoes grown in them increases yields. They are even using them for winter growing. What are this sites plans for the polytunnel versus the solar passive greenhouse?
not really the same thing, poly tunnels are not frost free but do extend the growing season while the greenhouse is 4 seasons all year round growing, hot beds might also be helpful
