Posted by Brooke Gilmore | Jan 20, 2021 Rocky Mountain Garlic (RMG) is building a passive solar greenhouse with an attached farm stand. Owners Tiffany and Mike Collette have started the new spring project to help ensure local food access for the community. This green house design is similar to the one being built by Rocky Mountain Garlic. Image courtesy of Tiffany Collette. The passive solar greenhouse will be 18 by 36 feet and features “smart” technology that will allow RMG to grow plant starts for their farm as well as other farmers. They will also use the space for growing through the winter. The greenhouse maintains a steady temperature without additional heat sources.
