4. Setup Instructions
Assembly of this greenhouse requires the participation of 1 to 2 people. Detailed step-by-step instructions with diagrams are typically included in the product packaging. Please refer to those for precise assembly. The general steps involve:
- Unpack Components: Carefully unpack all parts and verify against the component list provided in your product's specific manual.
- Assemble Steel Frame: Connect the steel poles and connectors according to the provided diagrams to form the arched structure. Ensure all connections are secure.
- Drape PE Cover: Carefully place the transparent PE cover over the assembled steel frame. Ensure it is correctly aligned and covers the entire structure.
- Secure to Ground: Utilize the extra-long flap of the cover by burying it or weighing it down with soil/rocks to enhance stability. Use the 12 ground stakes to firmly anchor the greenhouse to the ground.
- Attach Guy Ropes: For additional stability, especially in windy conditions, attach the 4 guy ropes to designated points on the frame and secure them to the ground using additional stakes (if not already included or if stronger anchoring is desired).
5. Operating Instructions
5.1 Access and Ventilation
- Roll-up Door: The front of the greenhouse features a roll-up door (113 cm W x 178 cm H) for easy access. Unzip and roll up the door, securing it at the top to keep it open when entering, exiting, or performing tasks inside.
- Mesh Windows: The greenhouse is equipped with mesh windows (65 cm W x 55 cm H) to facilitate air circulation. Open these windows as needed to provide adequate ventilation, regulate temperature, and prevent excessive humidity, while keeping insects out.


5.2 Environmental Control
- Sunlight: The transparent PE cover is designed to maximize sunlight penetration, crucial for photosynthesis.
- Protection: The cover protects plants from cold, rain, wind, and UV radiation, creating a stable growing environment. The PE cover is bird-proof, UV resistant, tear-proof, and aids in heat preservation.

6. Maintenance
- Cleaning the Cover: Regularly clean the PE cover with mild soap and water to remove dirt and debris, ensuring maximum light transmission. Avoid abrasive cleaners that could damage the material.
- Frame Inspection: Periodically check the steel frame for any signs of rust, damage, or loose connections. Tighten any loose bolts or replace damaged parts as necessary.
- Anchoring Check: Ensure that the ground stakes and guy ropes remain firmly secured, especially after strong winds or heavy rain. Re-anchor if needed to maintain stability.
- Ventilation System: Keep the zippers of the roll-up door and the mesh windows clean and functional. Lubricate zippers if they become stiff.
7. Troubleshooting
- Greenhouse Instability: If the greenhouse feels unstable, ensure all ground stakes are fully inserted and the guy ropes are taut and securely anchored. Verify that the extra-long cover flap is properly weighed down.
- Poor Air Circulation/High Humidity: Open the mesh windows and roll-up door to increase airflow. Consider using a small fan inside if natural ventilation is insufficient in very humid conditions.
- Water Accumulation on Roof: The arched roof is designed to prevent water pooling. If water accumulates, check for any sagging in the frame or cover that might be obstructing runoff. Ensure the frame is assembled correctly and taut.
- Cover Damage: For minor tears, repair kits for PE material may be available. For significant damage, consider replacing the cover to maintain optimal protection.
8. User Tips
No specific user tips from reviews or Q&A are available at this time. However, general tips for greenhouse use include:
- Site Selection: Choose a level, well-drained site that receives adequate sunlight throughout the day.
- Anchoring: Always ensure the greenhouse is securely anchored to the ground, especially in areas prone to strong winds.
- Temperature Monitoring: Use a thermometer inside the greenhouse to monitor temperatures and adjust ventilation as needed to prevent overheating or freezing.
- Pest Control: While mesh windows help, regularly inspect plants for pests and take appropriate measures.
