Greenway Services:Polyhouse suppliers

There are several types of playhouses, each designed to meet different agricultural needs and environmental conditions. Here are some common

Types of Polyhouse We Offer

1. Net House

• Description: Made of shade nets, these structures provide protection against pests and harsh sunlight while allowing airflow.

• Uses: Ideal for growing shade-loving plants and for hardening seedlings.

2. Low Tunnel Polyhouse

• Description: These are low structures covered with plastic, often supported by hoops or arches.

• Uses: Suitable for extending the growing season for crops like vegetables and flowers in cooler climates.

3. High Tunnel Polyhouse

• Description: Taller than low tunnels, high tunnels are typically used to protect crops from extreme weather conditions while allowing some ventilation.

• Uses: Common for high-value crops like tomatoes, cucumbers, and berries.

4. Ventilated Polyhouse

• Description: Equipped with side walls that can be opened or closed to control temperature and humidity levels.

• Uses: Suitable for crops that require specific environmental conditions, such as orchids and leafy greens.

5. Climate-Controlled Polyhouse

• Description: Features advanced technology for monitoring and controlling temperature, humidity, and light levels.

• Uses: Ideal for high-value crops that need precise environmental management, such as medicinal plants and exotic flowers.

6. Hydroponic Polyhouse

• Description: Designed specifically for hydroponic systems, where plants are grown in nutrient-rich water rather than soil.

• Uses: Efficient for growing leafy greens and herbs with minimal water usage.

7. Multilayer Polyhouse

• Description: Incorporates multiple layers of plastic or shade netting to provide additional protection against weather and pests.

• Uses: Effective for growing delicate crops that require more controlled environments.

8. Double-Skinned Polyhouse

• Description: Features two layers of plastic with air in between, providing better insulation and energy efficiency.

• Uses: Beneficial for regions with extreme temperature variations, helping to maintain a stable internal climate.

9. Modular Polyhouse

• Description: Composed of modular sections that can be expanded or customized based on specific agricultural needs.

• Uses: Flexible for farmers who may want to scale their operations over time.

types of polyhouse cooling systems:

1. Evaporative Cooling System

• Description: This system uses the principle of evaporation to cool the air inside the polyhouse. Water is circulated through pads or misters, and as the water evaporates, it cools the surrounding air.

• Components: Water pumps, cooling pads or misting systems, fans for air circulation.

• Benefits: Effective in hot and dry climates; lowers temperature significantly while adding humidity.

2. Ventilation System

• Description: This system relies on natural or mechanical ventilation to cool the polyhouse. Hot air is expelled, and cooler air is drawn in.

• Components: Exhaust fans, inlet vents, and sidewalls that can be opened.

• Benefits: Provides fresh air circulation and helps control humidity levels; can be combined with evaporative cooling for enhanced effectiveness.

3. Shade Cloth

• Description: Shade cloth can be used to cover parts of the polyhouse, reducing direct sunlight and lowering temperatures inside.

• Components: Shade fabric with varying percentages of shading based on crop needs.

• Benefits: Simple and cost-effective; protects plants from excessive heat and UV radiation.

4. Misting System

• Description: A misting system sprays a fine mist of water into the air, which cools the surrounding environment through evaporation.

• Components: High-pressure pumps, misting nozzles, and water supply.

• Benefits: Quickly reduces temperature and increases humidity; ideal for sensitive crops requiring high moisture levels.

5. Fogging System

• Description: Similar to misting, fogging systems produce ultra-fine water droplets that evaporate quickly, cooling the air.

• Components: High-pressure pumps, fogging nozzles, and a water source.

• Benefits: Provides efficient cooling with minimal water usage; maintains high humidity levels suitable for certain crops.

6. Thermal Mass Cooling

• Description: This method uses materials with high thermal mass (like water barrels or concrete) to absorb heat during the day and release it at night.

• Components: Water containers, concrete walls, or flooring.

• Benefits: Passive cooling solution that helps stabilize temperature fluctuations; reduces energy consumption.

7. Soil Cooling

• Description: This technique involves maintaining cooler soil temperatures, which can help lower the overall temperature in the polyhouse.

• Components: Insulation materials, mulching, or the use of reflective ground covers.

• Benefits: Helps regulate root zone temperatures and improves plant health.

8. Air Conditioning Systems

• Description: For high-value crops that require precise temperature control, air conditioning units can be installed in polyhouses.

• Components: Central or split-system air conditioners, ducting, and thermostats.

• Benefits: Provides accurate temperature control; suitable for high-tech, climate-controlled polyhouse operations.
