Why build a rammed earth wall for a greenhouse? The main reason is to store heat and increase the growing season. The thickness of the rammed earth wall allows for solar energy to be absorbed and released slowly, this helps to increase the temperature at night as the heat is slowly released. During the spring and fall when the weather is cooler but the sun is still shining, it will raise the greenhouse temperature and help to increase the growing season. As you can see from the layering and pieces of marble, granite and slate we can use our creativity to create art as well!
