Being in Colorado, we often think of passive solar greenhouses as great structures for growing in high altitude cold seasonal climate environments. After all a good passive solar greenhouse, like the ones designed by our partners at Ceres Greenhouse Solutions in Boulder, is an excellent way to grow year round with less energy resources than the typical inefficiencies of common greenhouse structures. However, when it comes to growing in Florida, or other traditionally hot and humid climates, the question of whether or not a highly insulated “cold climate” structure is necessary is certainly worth exploring. For a deeper understanding of actual energy utilization please visit the Ceres website to learn more about their greenhouses and energy calculations.
