5. Operating Instructions
Proper operation ensures optimal plant growth and greenhouse longevity.
- Ventilation: Utilize the two zippered roll-up doors to control airflow and temperature inside the greenhouse. Roll them up during warmer periods for ventilation and roll them down to retain heat.
- Humidity Control: To increase humidity, place a container of water inside the greenhouse. This is particularly beneficial for tropical plants or seedlings.

6. Maintenance
Regular maintenance will extend the life of your greenhouse.
- Cleaning: Periodically clean the PE cover with mild soap and water to ensure maximum light penetration. Avoid abrasive cleaners.
- Frame Inspection: Regularly check all pole connections and connectors for tightness and stability. Re-secure any loose parts.
- Cover Integrity: Inspect the PE cover for any tears or damage. Small tears can be repaired with greenhouse repair tape to prevent further damage.
- Anchoring: Ensure the ground stakes remain firmly in place and any additional weights are secure, especially after strong winds.

7. Troubleshooting
Here are solutions to common issues you might encounter:
- Greenhouse unstable in wind: Ensure all ground stakes are fully inserted. Place additional heavy objects (e.g., bricks, large stones) on the fabric skirt around the base. Consider using additional ropes or ties to secure the frame to a fixed structure.
- Zippers are stiff or stuck: Clean any dirt or debris from the zipper teeth. Apply a silicone-based lubricant or zipper wax to improve movement. Avoid forcing the zipper.
- Cover does not fit correctly: Double-check that the frame is assembled according to the instructions and that all poles are fully inserted into their connectors. Ensure the cover is oriented correctly before attempting to secure it.
- Insufficient heat retention: Ensure all doors are fully zipped down and secured. Check for any gaps or tears in the cover. Placing containers of water inside can help absorb heat during the day and release it slowly at night.
