4. Setup and Assembly Instructions
Follow these steps carefully for proper assembly. It is recommended to have at least two people for this process.
- Prepare the Site: Choose a level, well-drained area for your greenhouse. Clear any debris or sharp objects.
- Assemble the Frame: Connect the galvanized steel pipes according to the diagram provided in your separate assembly guide. Ensure all connections are secure. The frame includes 4 slant bracing tubes, a front cross bar, and middle reinforced tubes for enhanced stability.
- Install the PE Cover: Carefully drape the PE plastic cover over the assembled frame. Ensure it is centered and evenly distributed. The cover is designed to protect plants while allowing nourishing sunlight to pass through.
- Secure the Cover: Attach the cover to the frame using the included tether balls and double-side tape. Ensure the cover is taut to prevent water pooling.
- Anchor the Greenhouse: The overlong edges of the cover should be deeply buried in the soil (approximately 30cm/11.75 inches) to provide a secure base. Additionally, use the 4 screw stakes and 4 rods to firmly anchor the greenhouse to the ground. Utilize the guy ropes and spiral ground stakes for extra stability, especially in areas prone to wind.

5. Operating Instructions
Proper operation ensures the best growing conditions for your plants.
- Using the Roll-Up Zippered Door: The large zippered roll-up door provides easy access to the interior. Unzip the door and roll it up, securing it at the top to keep it open. This allows for easy entry, exit, and movement of equipment.
- Utilizing Roll-Up Mesh Windows: The greenhouse features eight roll-up windows with netting. These windows are crucial for cross-ventilation and climate control. Roll them up to allow air circulation and prevent overheating, while the netting keeps birds and larger insects out.
- Climate Control: Monitor the internal temperature and humidity. Adjust the number of open windows and the door position to maintain optimal conditions for your specific plants.

6. Maintenance
Regular maintenance will prolong the life of your greenhouse.
- Cleaning the Cover: Periodically clean the PE plastic cover with mild soap and water to ensure maximum light transmission. Avoid abrasive cleaners or brushes that could damage the material.
- Frame Inspection: Regularly check the galvanized steel frame for any signs of rust, corrosion, or loose connections. Tighten bolts as needed.
- Anchoring Check: Inspect the ground anchors and buried cover edges periodically, especially after strong winds, to ensure the greenhouse remains securely fastened.
- Zipper Care: Handle the zippers gently. If they become stiff, apply a silicone-based lubricant to ensure smooth operation. Avoid forcing stuck zippers.
- Weather Preparedness: As noted in safety, remove the cover during heavy snow, strong winds, or heavy rain to prevent structural damage.

7. Troubleshooting
Refer to this section for common issues and their solutions.
- Problem: Greenhouse instability or movement in wind.
Solution: Ensure all frame connections are tight. Verify that the overlong cover edges are deeply buried and that all screw stakes, rods, guy ropes, and spiral ground stakes are properly installed and secured. Consider adding additional weight to the base if in a very windy area. - Problem: Excessive heat buildup inside the greenhouse.
Solution: Open the roll-up mesh windows and the zippered door to increase air circulation. Consider adding a shade cloth over the top during peak summer months if temperatures remain too high. - Problem: Zippers are difficult to operate or have broken.
Solution: Apply a silicone-based lubricant to the zipper teeth to improve movement. Avoid forcing zippers. If a zipper is broken, it may require repair or replacement of the cover. - Problem: Water pooling on the roof of the greenhouse.
Solution: Ensure the PE cover is installed tautly and evenly over the frame. Check for any sagging areas and adjust the cover tension if possible. Clear any debris (leaves, branches) that may accumulate on the roof.
