Cold weather greenhouses are unique from regular greenhouses in their ability to retain heat during colder months. These are specifically designed to withstand freezing temperatures using features like double-layered walls, insulated panels, or thermal mass to reduce heat loss.
While regular greenhouses typically rely solely on ambient sunlight for warmth, cold weather greenhouses often use supplemental heating systems or passive solar techniques to ensure adequate temperatures for plant growth. They may also use specialized ventilations systems that minimize heat loss.
