Choose a level, well-drained area for your greenhouse. Ensure it receives adequate sunlight for your plants. Consider wind exposure and proximity to water sources.

Step 4: Secure the Greenhouse
The cover features an extra 4-inch edge designed to be buried in the soil. This helps to seal the greenhouse and increase its stability against wind. Bury this edge deeply into the surrounding soil. For additional stability, especially in windy areas, consider placing heavy objects like pavers on the bottom frame or using ground stakes (not included).

5. Operating Instructions
Ventilation
The greenhouse features three roll-up zippered doors. Open these doors to provide ventilation and allow fresh air to circulate, preventing excessive heat buildup and humidity. This is crucial for plant health, especially on warm days.

Plant Care
The clear PVC cover allows sunlight to reach your plants while blocking harmful UV rays. Monitor the temperature and humidity inside the greenhouse regularly. Water plants as needed, considering the reduced evaporation rate inside the enclosed space.

6. Maintenance
Cleaning
Clean the PVC cover periodically with a soft cloth and mild soapy water to ensure maximum light transmission. Avoid harsh chemicals or abrasive materials that could damage the cover.
Inspection
Regularly inspect the steel frame for any signs of rust or damage. Check the zippers and ties on the cover for wear and tear. Repair or replace damaged components promptly to maintain the greenhouse's integrity.
Seasonal Storage
If storing the greenhouse for the off-season, clean the cover and frame thoroughly. Disassemble the frame if desired for compact storage. Store the components in a dry, protected area away from direct sunlight to prolong their lifespan.
7. Troubleshooting
Greenhouse is unstable or blows away in wind.
- Solution: Ensure the 4-inch extended edges of the cover are deeply buried in the soil. Place heavy objects like pavers or sandbags on the bottom frame for added weight. Consider using additional ground stakes or anchors (not included) to secure the frame to the ground.
Cover does not fit properly or tears during assembly.
- Solution: Double-check that the frame is assembled correctly and all pipes are fully seated into their connectors. The cover should be stretched gently over the frame. If the cover is too tight, ensure the frame dimensions match the product specifications. Contact customer support if the cover is defective.
Zippers are not working smoothly or break.
- Solution: Apply a silicone-based lubricant to the zipper teeth to improve movement. Avoid forcing stuck zippers. If a zipper breaks, it may require repair or replacement of the cover.
