Final answer:
An American greenhouse consists of a frame, glass or polycarbonate panels, insulation, heating and ventilation systems, irrigation system, shading and screening installations, and benching.
Step-by-step explanation:
An American greenhouse typically consists of the following components:
- Frame: The structure of the greenhouse made of materials like aluminum or galvanized steel.
- Glass or Polycarbonate Panels: The translucent walls and roof that allow sunlight to enter the greenhouse.
- Insulation: Materials such as bubble wrap or fiberglass used to retain heat inside the greenhouse.
- Heating and Ventilation: Systems to regulate temperature and airflow within the greenhouse.
- Irrigation System: Equipment and pipes used to provide water to the plants.
- Shading and Screening: Installations that control the amount of light and protect the plants from pests.
- Benching: Tables or racks used to hold the plants or containers.
These components are common in high-profile American greenhouses and help create the optimal conditions for plant growth.
