2. Setup and Assembly
Careful assembly is crucial for the stability and longevity of your Dancover Tunnel Greenhouse. Please ensure you have all components before beginning. It is recommended to assemble the greenhouse on a level surface and with the assistance of at least one other person.
2.1 Unpacking and Component Check
- Unpack all boxes and lay out the components.
- Verify all parts against the packing list provided with your product. Contact Dancover support immediately if any parts are missing or damaged.
2.2 Frame Assembly
The frame consists of galvanized steel tubes (25 x 0.6 mm). Follow the step-by-step instructions in the separate assembly guide included in your package. Ensure all connections are secure and tightened appropriately to form a rigid structure.
2.3 Cover Installation
Once the frame is fully assembled and secured, carefully drape the transparent film cover over the structure. Ensure the cover is centered and evenly distributed.

4.1 Seasonal Use and Storage
This greenhouse is designed for seasonal use, typically from early spring to late summer or early autumn, depending on local weather conditions. It is a lightweight structure and not designed to withstand heavy snow loads or strong winds typical of winter. For optimal longevity:
- Before Winter: Disassemble the greenhouse and store the frame and cover in a dry, protected area during the off-season.
- High Winds: In anticipation of strong winds, consider temporarily removing the cover or reinforcing the structure.
4.2 Cleaning
Clean the transparent cover periodically to ensure maximum light transmission. Use mild soap and water with a soft cloth or sponge. Avoid abrasive cleaners or brushes that could damage the film.
4.3 Frame Inspection
Regularly inspect the galvanized steel frame for any signs of rust, damage, or loose connections. Tighten any loose bolts and address any rust spots promptly to maintain structural integrity.
5. Troubleshooting
This section addresses common issues you might encounter with your Dancover Tunnel Greenhouse.
5.1 Excessive Heat Inside Greenhouse
- Cause: Insufficient ventilation.
- Solution: Ensure both end doors are fully open and all three mesh windows are rolled up during warm periods to maximize airflow.
5.2 Condensation Build-up
