- Zipper and Buckle Functionality: Ensure zippers and buckles operate smoothly. Lubricate zippers if they become stiff.
6. Troubleshooting
This section addresses common issues you might encounter with your greenhouse.
- Greenhouse Instability: If the greenhouse feels unstable, re-check all anchoring points. Ensure the base is properly weighted down or buried, and all ropes are taut. Consider adding additional ground pegs in very windy areas.
- Excessive Humidity: Increase ventilation by opening the mesh door and all roll-up windows. Ensure adequate air circulation around plants.
- Insufficient Warmth: Ensure the PE cover door and all windows are securely closed. Check for any gaps in the cover installation.
