A Qatari customer purchased our 3,000-square-meter film greenhouse. The length of the greenhouse is 64 meters and the width is 54 meters. Height 6 meters, used for hydroponic lettuce. This greenhouse is equipped with an internal and external sunshade system, a fan wet curtain cooling system, a top-opening window ventilation system, and a circulation extension circulation system. This greenhouse was built in 2020 and has been in use for 5 years. Everything is running well.

A customer in Uruguay purchased more than 12,000 square meters of film greenhouses. There are fan and water curtain cooling systems, and internal sunshade system. This ordinary multi-span film greenhouse is easy to build and can be put into use quickly. The cost is much lower than that of solar panel greenhouses and glass greenhouses. The only disadvantage is that the service life of the film is 5 years. Generally, after customers use it for 3 years, the customer will replace the film with a new one due to the decrease in light transmittance affecting crop growth. For crops that do not require high light, the film can be used for 5 years or even longer. This greenhouse will be put into operation in 2021 and is currently in good condition.

Greenhouses have come a long way since their humble beginnings, evolving from simple structures to sophisticated technological marvels. This journey reflects the ever-changing needs of agriculture, horticulture, and our quest for a sustainable future. In ancient times, the concept of a controlled environment for plant growth can be traced back to the Roman Empire. The Romans built rudimentary structures known as "specularia," which were used to grow exotic plants. These early greenhouses were essentially large rooms with transparent materials, such as mica or oiled cloth, to allow sunlight to enter. However, they were mainly used for the pleasure of the wealthy and did not have the advanced features we associate with modern greenhouses. During the Middle Ages, the art of growing plants in controlled environments was largely forgotten. It wasn't until the Renaissance that interest in horticulture was rekindled. Wealthy nobles and scholars began to build small gardens with glass-covered enclosures to protect delicate plants from the harsh elements. These early glasshouses were still relatively simple in design but marked the beginning of a new era in plant cultivation. Today, greenhouses are an integral part of modern agriculture and horticulture. They come in a wide variety of sizes and designs, from small backyard hobby greenhouses to large commercial operations. Advanced technologies such as computerized climate control, LED lighting, and hydroponics are being used to optimize plant growth and maximize yields. Greenhouses are also playing an important role in sustainable agriculture by reducing water consumption, minimizing pesticide use, and enabling year-round production in areas with harsh climates.

Natural ventilation systems for different greenhouse types.

In order to achieve natural ventilation, ventilation windows such as roof windows and side windows are set up in the greenhouse to form a greenhouse natural ventilation system. According to the different characteristics of each type of greenhouse, different ventilation window settings and ventilation window opening and closing types are adopted to determine sufficient wind window area to form different types of natural ventilation systems.
