4. Assembly Instructions

Follow these steps carefully to assemble your GOWE Walk-in Tunnel Greenhouse. It is recommended to have at least two people for assembly.

This diagram illustrates the internal metal frame of the greenhouse, emphasizing key structural enhancements such as V-shaped diagonal braces for wall reinforcement, top reinforcement braces for stability, and a reinforced door frame.

1. Prepare the Site: Clear the chosen area of debris and ensure the ground is level.
2. Assemble the Base Frame: Connect the base poles according to the diagram, ensuring all connections are secure.
3. Install Arch Supports: Attach the arched poles to the base frame, forming the tunnel shape.
4. Reinforce Structure: Install the V-braces to reinforce the walls, the four rods to reinforce the door frame, and the six diagonal braces to hold the top steady. Ensure all bolts are tightened.
5. Attach the Cover: Carefully drape the 140 GSM PE cover over the assembled frame. Ensure the cover is centered and evenly distributed.
6. Secure the Cover: Fasten the cover to the frame using the provided ties or clips. Bury the extended edges of the cover into the soil around the perimeter of the greenhouse to prevent wind from lifting it.
7. Install Door and Windows: Ensure the zippered roll-up door and mesh windows are properly aligned and functional.
8. Anchor the Greenhouse: Use the provided ground stakes and guy ropes to firmly anchor the greenhouse to the ground. Pull the guy ropes tightly from the ground stakes to reduce wind obstruction.

5. Operating Instructions

• Ventilation: Utilize the eight mesh windows and the roll-up door to control heat and humidity inside the greenhouse. Open them during warm periods to allow airflow and prevent excessive temperatures.
• Access: The large zippered roll-up door provides easy access for walking in tools and tending to plants. Ensure the zipper is fully closed when not in use to maintain internal conditions and deter pests.
• Sunlight: The heavy-duty cover allows approximately 85% of nourishing sunlight to pass through while stopping harmful UV scorching, creating an optimal growing environment.

6. Maintenance

• Regular Inspection: Periodically check all frame connections, bolts, and anchors to ensure they remain tight and secure.
• Cover Care: Clean the greenhouse cover gently with mild soap and water as needed. Avoid abrasive cleaners or tools that could damage the PE material.
• Wind Protection: Regularly inspect the ground stakes and guy ropes, especially after strong winds, to ensure the greenhouse remains firmly anchored. Re-bury the extended cover edges if they become exposed.
• Snow Removal: The sloped roof design helps shed rain and snow. However, in areas with heavy snowfall, it is advisable to gently remove excessive snow accumulation from the roof to prevent structural stress.
• Zipper Maintenance: Keep the door zipper clean and lubricated if necessary to ensure smooth operation.

7. Troubleshooting

• Greenhouse Instability: Ensure all frame connections are tightened. Verify that ground stakes are fully inserted and guy ropes are taut. Confirm the cover edges are buried in the soil.
• Excessive Heat/Humidity: Open the roll-up door and multiple mesh windows to increase ventilation. Consider adding a small fan for improved air circulation if needed.
• Water Accumulation on Roof: While the roof is sloped, ensure no debris is obstructing water runoff. In heavy rain, check for any sagging areas that might collect water and adjust the cover tension if possible.
• Damaged Cover: For minor tears, use a greenhouse repair tape. For significant damage, contact customer support for replacement options.
