7. Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor Ventilation / Overheating | Roof vent closed; insufficient airflow. | Open or adjust the roof vent to allow more air circulation. Ensure sliding door is not fully sealed if more airflow is needed. |
| Water Accumulation on Roof | Clogged rain gutters or drainage ports. | Clear gutters and drainage ports of debris. Ensure the sloped roof is correctly installed. |
| Panels Seem Loose | Panels not fully seated in grooves; frame fasteners loose. | Ensure all panels are correctly slid into their grooves. Check and tighten all frame screws and fasteners. |
| Door Sticking / Hard to Slide | Debris in track; track needs lubrication. | Clean the door tracks thoroughly. Apply a silicone-based lubricant to the tracks if necessary. |
| Greenhouse Instability | Ground anchors not properly installed or loose. | Verify that all spiral ground anchors are fully inserted and secure. Ensure the greenhouse is on a level surface. |
