Commercial glass greenhouses are often high tech production facilities for vegetables or flowers.
A greenhouse is a structural building with different types of covering materials, such as a glass or plastic roof and frequently glass or plastic walls; it heats up because incoming visible sunshine is absorbed inside the structure.
