If you encounter any issues with your greenhouse, refer to the following common troubleshooting tips:
- Water Leaks: If water leaks occur, re-inspect all panel seams and joints. Apply additional waterproof sealant where necessary. Ensure the roof vent and door are properly closed and sealed.
- Panel Instability: If panels feel loose, check the securing strips and ensure they are properly inserted and the frame is rigid. Verify all frame connections are tight.
- Door/Vent Sticking: Lubricate hinges and check for any obstructions. Ensure the frame is level, as an uneven base can cause alignment issues.
