Greenhouse planting is an important branch of modern agriculture. One of the biggest challenges of greenhouse planting is to create and maintain a stable and consistent environment for plant growth. Without a reliable climate, the growth of plants is often unsatisfactory. Once losing control of the environment, plants will have more serious problems: powdery mildew and gray mold, commonly known as bud rot. Any of these problems can disrupt growth and lead to property losses. The three most important aspects of humidity control and dehumidification in greenhouse or hydroponic planting are the proper size, reasonable location, and airflow.
