warm greenhouse

A warm greenhouse is a controlled environment designed to protect plants and facilitate their growth, maintaining nighttime temperatures between 10–13 °C (50–55 °F). These structures, typically made of glass or plastic, allow sunlight to enter for photosynthesis while regulating interior temperature and humidity.12

Warm greenhouses are suitable for plants like begonias, African violets, orchids, and roses. They are crucial in agriculture and horticulture for growing crops like tomatoes and ornamental plants, especially in climates where outdoor conditions are unfavorable. Unlike the atmospheric greenhouse effect, which involves gases trapping heat, a physical greenhouse uses its structure to manage temperature.123
