6. Maintenance

• Cleaning: Clean polycarbonate panels regularly with mild soap and water to remove dirt and algae, ensuring maximum light transmission. Avoid abrasive cleaners.
• Frame Inspection: Periodically check all frame connections and fasteners. Tighten any loose bolts or screws to maintain structural integrity.
• Ventilation System: Ensure roof vents and sliding door mechanisms operate smoothly. Lubricate moving parts if necessary.
• Anchoring: Verify that the greenhouse remains securely anchored, especially after strong winds or heavy rainfall. Re-secure ground spikes or anchors if they become loose.
• Panel Integrity: Inspect polycarbonate panels for any cracks or damage. Replace damaged panels promptly to maintain insulation and protection. Year-round part replacements are available.

7. Troubleshooting

• Greenhouse Instability: If the greenhouse feels unstable, ensure all frame components are correctly assembled and all anchors are fully secured into the ground. Verify the ground surface is level.
• Excessive Condensation: Increase ventilation by opening the roof vents or the sliding door to reduce humidity and condensation buildup.
• Loose Panels: Check that all polycarbonate panels are properly seated in their channels and that retaining buckles are engaged. Re-install any panels that have come loose.
• Difficulty Sliding Door: Inspect the door track for debris and clean if necessary. Ensure the door is properly aligned on its rollers.
• Water Leaks: Check for gaps in panel installation or damaged seals. Apply silicone sealant if minor gaps are found.
