Deep Winter Greenhouse Open House

The UMN Regional Sustainable Development Partnerships, the Lake City Catholic Worker Farm, and the Sustainable Farming Association are excited to announce the next open house (and potluck) of our Deep Winter Greenhouse (DWG) campaign to help producers build passive solar greenhouses developed by the University of Minnesota Center for Sustainable Building Research.

This open house will occur on Saturday, May 5 from 4:00 to 7:00 pm at the Lake City Catholic Worker Farm, in Lake City, Minnesota. The Lake City Catholic Worker Farm is one of five producers and community organizations that was chosen to participate in the University of Minnesota Regional Sustainable Development Partnership’s campaign to spread awareness of this technology and to conduct research on the production and financial capacity of the system. Please see the attached flier for more information. 

DWGs use passive solar heat collected from the sun in the day which is stored in an underground rock bed. At night that heat dissipates into the enclosure above to allow cold tolerant crops to grow. This technology will help small- and mid-sized farms increase their revenue potential helping to keep small farmers on the land and increase access to fresh locally grown food. 

The University of Minnesota's Regional Sustainable Development Partnerships is proud to support our local producers and community groups that are experimenting with novel technology to enrich our communities. Attend this open house, learn about passive solar greenhouses, ask questions, and enjoy yourself!
This event is also a potluck.... so feel free to bring a dish to share and bring plates and utensils to cut down on waste.

See the flier for more details.
