The Urban Farm Podcast With Greg Peterson

179: Penn Parmenter on Passive Solar Greenhouses. Designing greenhouses using the natural laws of nature as allies and resources. Since 1992 Penn and her husband Cord have been growing food just above the 8,000 feet level in the Wet Mountains of South Central Colorado. With many years of research and development, they founded Smart Greenhouses LLC and Miss Penn’s Mountain Seeds in 2013, Together they build smart greenhouses all over the Rocky Mountain West at even the highest elevations. Their greenhouses are 100% sustainable as they heat, cool and ventilate themselves without the use of fossil fuel. Penn and Cord are also co-instructors at the Denver Botanic Gardens teaching a slew of high-altitude growing classes there and around the region.  Their very popular day-long Sustainable Greenhouse Design class is held on their 43-acre property and at the Denver Botanic Gardens. IN THIS PODCAST: Greg connects again with Penn to talk about the greenhouse designs she and her husband create, sell and teach about. Pe
