Step-by-Step Assembly:
- Assemble Arch Sections:
Connect the curved galvanized steel pipes to form the arch sections. Ensure the holes align for secure fastening. Use the provided bolts and nuts to secure each connection point. You will create multiple arch sections.

- Assemble Base Corner Supports:
Connect vertical pipes to horizontal base pipes to form the corner supports for the greenhouse base. Secure these connections with bolts and nuts.
- Connect Arches to Corner Supports:
Stand the assembled arch sections upright and connect them to the base corner supports. Ensure they are properly aligned and secured with fasteners.
- Assemble Main Base Frame:
Connect the base corner supports with additional straight horizontal pipes to complete the rectangular base frame. Secure all connections firmly.
- Install Horizontal Crossbars:
Attach the horizontal crossbars between the arch sections and vertical supports. These bars provide crucial structural integrity. Secure them firmly with the provided fasteners.
- Drape and Secure the PE Fabric Cover:
Carefully drape the PE fabric cover over the assembled frame. Ensure it is centered and evenly distributed. Fasten the cover to the frame using the integrated ties, straps, or clips. The bottom edge of the cover has an extension designed to be weighted down with stones or sandbags for added stability.

- Anchor the Greenhouse:
Utilize the provided ground pegs and ropes to anchor the greenhouse firmly to the ground. This is crucial for stability, especially in windy conditions. We highly advise installing all ground pegs. Place heavy objects like rocks or sandbags on the bottom skirt of the cover for additional security.

- Operate Doors and Windows:
Ensure the zipper doors operate smoothly and the window flaps can be rolled up and secured for ventilation. The fixed door crossbars should be in place to maintain door integrity.

5. Operating Instructions
Ventilation:
Your greenhouse is equipped with 16 double-screen windows. To regulate temperature and humidity, roll up the window flaps and secure them using the safety buckles. This allows for cross-ventilation while keeping pests out. Close windows during cooler temperatures or adverse weather.
Access:
The greenhouse features two zipper doors located at each end. Use the zippers to open and close the doors. For extended periods of access or to maximize airflow, the doors can be rolled up and secured at the top.

6. Maintenance
- Cleaning: Clean the PE fabric cover periodically with mild soap and water. Avoid harsh chemicals or abrasive cleaners that could damage the material.
- Frame Inspection: Regularly check all frame connections, bolts, and nuts for tightness. Tighten any loose fasteners to maintain structural integrity.
- Cover Inspection: Inspect the PE cover for any tears, punctures, or signs of wear. Small tears can often be repaired with specialized greenhouse repair tape to prevent further damage.
- Anchoring: Ensure ground pegs and ropes remain securely anchored, especially after strong winds or heavy rainfall. Re-secure or reinforce as needed.
- Snow Removal: In areas with heavy snowfall, gently remove accumulated snow from the roof to prevent excessive weight from damaging the structure.

7. Troubleshooting
- Greenhouse feels unstable: Ensure all frame connections are tightened. Verify that ground pegs are fully inserted and ropes are taut. Add additional weight to the bottom skirt (e.g., rocks, sandbags) as recommended.
- Water pooling on the roof: Check that the cover is stretched tightly and evenly over the frame. Ensure no structural components are bent or misaligned, which could create depressions.
- Excessive condensation inside: Increase ventilation by opening more windows or partially opening the doors. Ensure adequate airflow to reduce humidity.
- Zipper sticking: Apply a silicone-based lubricant to the zipper teeth. Ensure the fabric is not caught in the zipper mechanism.
