Setup Instructions
Follow these steps carefully to assemble your greenhouse:
- Step 1: Assemble the Base Frame.
Connect two 1A poles with two 1B poles using four A-connectors to form two long side frames. Then, connect these two long side frames with two 4A poles and two 4B poles to create the rectangular base. - Step 2: Erect the Vertical Supports.
Insert the 3A and 3B vertical poles into the A-connectors on the base frame to raise the structure. - Step 3: Install the Roof Structure.
Attach the F and G top corner connectors to the top of the vertical poles. Then, connect the 2 crossbar poles and 5 roof support poles to complete the roof frame. - Step 4: Place the Greenhouse Cover.
Carefully drape the greenhouse cover (Part 6) over the assembled frame, ensuring it fits snugly. Secure the cover to the frame using the built-in straps and buckles. - Step 5: Secure the Greenhouse.
Use the provided wind ropes and metal stakes (Part 7) to secure the greenhouse to the ground. Place sand, soil, rocks, or weight bags into the unique bottom sandbag pockets along the sides of the cover to prevent wobbling or movement in windy conditions.

Operating Instructions
- Access: The greenhouse is equipped with two zippered doors located at the front and back. Unzip completely to open for easy walk-through access.
- Ventilation: Two mesh side windows ensure proper ventilation and airflow. Roll up the window flaps and secure them to allow air circulation and prevent overheating.
- Temperature Control: Close the doors and windows to retain heat and protect plants from cold. Open them to release excess heat and provide fresh air.
- Stability: Ensure the bottom sandbag pockets are filled with sufficient weight (sand, soil, or rocks) and the ground stakes are firmly in place to maintain stability against wind.

Maintenance
- Cleaning: Clean the polyethylene (PE) cover with mild soap and water. Avoid harsh chemicals that could damage the material.
- Inspection: Periodically check the frame for rust or damage and the cover for tears or holes. Repair any damage promptly to extend the life of the greenhouse.
- Storage: For long-term storage or during severe weather, disassemble the greenhouse and store it in a dry, protected area to prevent damage.
Troubleshooting
- Greenhouse unstable in wind: Ensure sandbag pockets are filled and ground stakes are fully inserted. Check that all frame connections are tight.
- Poor ventilation/overheating: Open both zippered doors and roll up the side windows to increase airflow.
- Water accumulation on roof: The gothic arch design is intended to shed water and snow. Ensure the cover is taut and properly secured to prevent sagging.
