Access
Use the heavy-duty zippers on the front and back doors for convenient entry and exit. Ensure zippers are fully closed when not in use to maintain the internal environment.
Maintenance
- Cleaning: Periodically clean the PE cover with mild soap and water to remove dirt and debris, ensuring maximum light penetration. Avoid abrasive cleaners.
- Inspection: Regularly check the frame poles, connectors, zippers, and cover for any signs of wear, damage, or loose connections. Address any issues promptly to prevent further damage.
- Seasonal Storage: The greenhouse is lightweight and portable. For prolonged periods of non-use or during severe weather, it is recommended to disassemble and store the greenhouse in a dry, protected area.
- Winter Use: The gothic arch design helps snow and rain slide off, preventing accumulation. However, in heavy snowfall, it is advisable to gently clear snow from the cover to prevent excessive weight.
Troubleshooting
- Greenhouse Instability: Ensure side pouches are filled with sufficient weight (sand, soil, or water bottles). Verify that windproof ropes are taut and ground pegs are securely inserted into the ground. Consider additional anchoring in very windy conditions.
- Poor Ventilation: Ensure both zipper doors and side mesh windows are open when ventilation is desired. Check for any obstructions blocking airflow.
- Zipper Malfunction: If zippers become stiff, apply a silicone-based lubricant. If a zipper is damaged, contact customer support for replacement parts.
- Water Accumulation: The gothic arch design is intended to shed water. If water accumulates, check for any sags in the cover and ensure the frame is correctly assembled and taut.
