Yesterday on The Garage Gardeners Radio Show we spoke with Rob Avis from Verge Permaculture about passive solar greenhouses. It was a great show. Rob helped us dig into things to consider when planning a passive solar greenhouse--bringing together biology, thermal dynamics, and building. We talked about glazing, orientation, insulation, ventilation, soil, irrigation, and thermal mass. Click here to listen.
Rob and his wife, Michelle, have a new book about rainwater harvesting coming out this fall. Find out more about Essential Rainwater Harvesting. It's a manual for designing, building, and maintaining a water harvesting system.
