Mountain Tomatoes

Rocky Mountain Gardening Elective

We all know the tomato is the gate-way drug to gardening, the Holy Grail of the mountains is to grow a red tomato. Technically, the mountains and tomatoes don’t get along and this class explains why.

Learn about tomato varieties from around the world, especially those grown in high, cold places. Learn how to find and adapt seed, create night-time protection, prepare soil, fight disease and enjoy the fruits of your labor. The world of tomato seed swapping is also explored.

Penn comes armed with high-altitude tomato seeds, plants, demos and tips for reaching success with the tomato. Join the addiction! No more green tomatoes! (Unless it's Green Zebra, or Green Doctors or Evergreen).

Sustainable Greenhouse Design

Rocky Mountain Gardening Elective

Have you ever wondered if a greenhouse that needs NO supplemental heating or cooling could be made? The answer is yes!

No more over-heating and freezing in all-glazed greenhouses. The sustainable design balances the use of thermal mass, glazing, insulation and sun angles to achieve the stabilization needed in our extreme climate without the use of fossil fuels. Learn how to design a sustainable greenhouse from the ground up, using salvaged or new materials to achieve the look and performance you want. You can also use these techniques to improve an existing greenhouse.

This class is a comprehensive look at how passive solar greenhouses work and covers topics such as how to orient the building, basic principles of passive solar design including the use of stored water as thermal mass, simple math formulas to help guide your design, a materials list and drawings and calculations for a 13’ x 15’ greenhouse.

In 2000, the Parmenters built their first greenhouse out of 90% recycled materials on top of an 8,120 ft. elevation decomposed granite mountain. Since then, they have designed and built many more and are ready to share what they have learned about state-of-the-art materials and cost-saving strategies.
