Thinking About a Backyard Greenhouse?

A backyard greenhouse can completely transform the way you garden — extending your season, protecting tender crops, and even allowing you to grow food year-round. But success inside a greenhouse depends on understanding the unique dynamics of an enclosed solar environment.

Join Barbra Airriess, greenhouse grower and owner of a geodesic dome, as she shares firsthand experience growing food through all four Colorado seasons. Paired with Dave Falasco, owner of Dome Creations, LLC, this class blends real-world growing insight with structural and design expertise.

Together, they’ll cover:

• Managing solar gain and temperature swings
• Humidity control and air circulation
• Creating healthy growing conditions year-round

• Types of greenhouses (including domes, hobby houses, and custom builds)
• Glazing materials: pros, cons, and performance in Colorado
• Ventilation systems and airflow design
• Heating and cooling considerations for our climate

• Setting up your greenhouse based on what you want to grow
• Watering systems and irrigation options
• Soil management and fertility in enclosed spaces
• Integrated Pest Management (IPM) strategies specific to greenhouses
• Seasonal tips and crop timing for continuous production

Whether you’re considering your first small hobby house or planning a more permanent structure, this class will help you understand both the mechanics and the growing strategy required for success.

Bring your questions, both Barb and Dave will be available for a Q&A session.

Grow longer. Grow smarter. Grow year-round.
