The key to the success of plastic greenhouse seedling cultivation is to control the temperature, humidity, light and ventilation. ‌ As a protected cultivation facility, the success of plastic greenhouses mainly depends on the precise management of these environmental factors.

Specifically, plastic greenhouses need to pay special attention to the following points:

‌Temperature control‌: Generally keep the temperature within 25℃～30℃ during the day, and the maximum temperature does not exceed 40℃.
‌Humidity management‌: Maintain appropriate humidity to avoid the impact of excessive or low humidity on crop growth.
‌Light regulation‌: Plastic film has good light transmittance, with a transmittance of 80%, ensuring sufficient light in the shed.
‌Ventilation control‌: Reasonable ventilation can regulate the temperature and humidity in the greenhouse, provide sufficient carbon dioxide, and promote crop growth.

In addition, it is also very important to choose the right building materials and design. For example, the use of high-density polyethylene covering materials has good thermal insulation and corrosion resistance. When designing, the orientation, size and building materials of the greenhouse should be considered to ensure the thermal insulation performance and service life of the greenhouse.
