Polyhouse Management Tips: Maintaining Ideal Temperature, Humidity and Light Levels

A polyhouse, or a greenhouse, is an enclosed structure designed to create an optimal plant-growing environment. It is typically made up of a metal or PVC frame covered with a transparent material, such as plastic film or glass, that allows sunlight to enter the structure. The primary purpose of a polyhouse is to protect plants from external environmental factors, such as wind, rain, and pests, and to provide a controlled environment for optimal plant growth and development. That is the reason Polyhouse management is essential for the successful operation of a polyhouse.

Polyhouses can grow various plants, including flowers, fruits, vegetables, and herbs. They are particularly useful for extending growing seasons in areas with short or unpredictable growing seasons and for growing plants that require a specific environment, such as tropical plants.

Polyhouses can also be used for research and experimentation in plant breeding and genetics and for producing plants for commercial sale. In addition, polyhouses can be used for educational purposes to teach students about the science of plant growth and environmental control.

Overall, the primary purpose of a polyhouse is to create an ideal environment for plant growth and development, which can result in higher yields, better quality crops, and an extended growing season.

Why proper management is important for a successful polyhouse:

Proper management is essential for the successful operation of a polyhouse. The environment within a polyhouse is highly controlled, and any variation in the environmental conditions can significantly impact plant growth and health. Here are some reasons why proper management is important for a successful polyhouse:

  1. Optimal plant growth: Proper management techniques, such as temperature and humidity control, irrigation, and fertilization, can help create the ideal growing conditions for plants, resulting in better growth and yield.
  2. Disease and pest prevention: Proper management techniques can help prevent the spread of diseases and pests that can easily thrive in the controlled environment of a polyhouse.
  3. Cost-effective operation: Proper management can help minimize unnecessary expenses, such as energy costs and plant replacement, which can result in cost
    savings and increased profitability.
  4. Compliance with regulations: Proper management can help ensure compliance with food safety regulations and environmental protection regulations.
  5. Efficient use of resources: Proper management techniques, such as efficient water and nutrient management, can help conserve resources and reduce waste.

Proper management is critical to a polyhouse and can result in healthier plants, higher yields, reduced costs, and increased profitability.

Factors to Consider when Planning a Polyhouse:

Here are some factors to consider when planning a polyhouse, described stepwise:

1: Determine the Purpose and Type of Polyhouse:

  1. Consider the purpose of the polyhouse, such as commercial production, research, or personal use
  2. Decide on the type of polyhouse needed based on the purpose, such as a freestanding, attached, or lean-to polyhouse

2: Choose the Location:

  1. Select a location with adequate sunlight, good drainage, and access to water and electricity
  2. Consider local zoning regulations and potential wind exposure in the location

3: Determine the Size and Shape of the Polyhouse:

  1. Consider the available space and the desired growing area when determining the size of the polyhouse
  2. Choose a shape that will best suit the growing needs and available space, such as a rectangular or circular shape

4: Select the Frame and Covering Materials:

  1. Choose a durable frame material, such as aluminum, galvanized steel, or PVC
  2. Choose a covering material that allows for proper light transmissions, such as glass, polycarbonate, or polyethylene film

5: Install Environmental Control Systems:

  1. Install systems for temperature control, ventilation, humidity control, and lighting
  2. Choose a system that is energy-efficient and reliable

6: Plan Irrigation and Fertilization Techniques:

  1. Determine the type of irrigation system needed, such as drip, overhead, or sub-surface irrigation
  2. Decide on the appropriate fertilization method and select a high-quality fertilizer

7: Implement Pest and Disease Control Measures:

  1. Develop a pest and disease management plan, including prevention and control measures
  2. Consider using organic and non-toxic methods when possible

8: Establish Crop Rotation and Succession Planning:

  1. Plan for crop rotation and succession to maintain soil health and prevent disease
  2. Determine the optimal planting and harvesting times for each crop

9: Consider Post-Harvest Management:

  1. Plan for efficient post-harvest handling and processing to maintain crop quality
  2. Ensure proper cleaning and disinfection to prevent contamination

By considering these factors when planning a polyhouse, you can ensure that it is properly designed and equipped for optimal plant growth and health.

Harvesting and post-harvest management:

Harvesting and post-harvest management are critical components of polyhouse management that determine the quality and value of the final product. Here are some tips for effective harvesting and post-harvest management in a polyhouse:

1-Timing of Harvest:

  1. Determine the optimal timing of harvest for each crop, which may vary depending on the type of crop, growing conditions, and intended use
  2. Use appropriate tools and techniques to harvest crops to minimize damage and maintain quality
  3. Harvest in the morning or evening when temperatures are cooler to reduce stress on plants

2-Cleaning and Disinfecting:

  1. Clean and disinfect all equipment, tools, and surfaces to prevent the spread of diseases and pests
  2. Use appropriate cleaning agents and methods to avoid damaging equipment and surfaces
  3. Implement regular cleaning and disinfection schedules to maintain a hygienic growing environment

Overall, effective harvesting and post-harvest management practices are essential for ensuring the quality and value of crops grown in a polyhouse. By carefully timing harvest, using appropriate methods for preserving crop quality, and implementing regular cleaning and disinfection practices, you can maintain a safe and healthy growing environment and maximize the value of your crop.


In conclusion, proper management is crucial for the success of a polyhouse. A well-managed polyhouse can provide optimal plant growth conditions, prevent the spread of diseases and pests, reduce costs, and increase profitability.

To achieve successful polyhouse management, it’s important to consider factors such as choosing the right location, selecting appropriate materials, installing environmental control systems, planning for irrigation and fertilization, and implementing pest and disease control measures.

Additionally, monitoring and regular maintenance are key components of successful management. Regular monitoring of environmental conditions, pest and disease outbreaks, and plant growth will help identify potential problems early and enable timely intervention.

Following these tips and incorporating proper management techniques can create an optimal plant-growing environment and achieve a successful and profitable polyhouse operation.
