If you’ve ever stared at your snow-covered backyard and thought, “Could I still grow food out there?”, you’re not alone. Edmonton’s outdoor growing season is short, but passive solar greenhouses can stretch it by months or even make it year-round.

In this 2-hour workshop, Kim Ross will show you the key concepts behind designing a four-season greenhouse that works with our cold, sunny climate. Whether you’re dreaming of winter kale or just tired of store-bought herbs, this session will help you rethink what’s possible.

• What makes a greenhouse “passive solar”, and why it works in Alberta
• How to keep plants warm at -30°C without a gas bill
• What glazing and materials perform best for our climate
• Simple design decisions that create big savings and better harvests
• How to grow greens, herbs, and veggies through all four seasons
• Why this approach is ideal for urban backyards and small-scale growers
