Operating Instructions
Ventilation:
The greenhouse is equipped with an adjustable roof vent window to provide balanced ventilation. Open the vent during warmer periods to prevent overheating and ensure adequate airflow for your plants. Close the vent during colder weather or rain to maintain internal temperature and protect plants.
UV Protection:
The polycarbonate panels feature a UV coating on their surfaces. Ensure the correct side of the panels faces outward during installation to maximize sunlight exposure while protecting plants from harmful solar radiation. This balance supports healthy plant growth.

Maintenance
- Cleaning: Regularly clean the polycarbonate panels with mild soap and water to ensure maximum light transmission. Avoid abrasive cleaners or tools that could scratch the surface.
- Frame Inspection: Periodically check all frame connections and fasteners for tightness. Tighten any loose screws to maintain structural integrity.
- Panel Inspection: Inspect panels for any cracks or damage. Replace damaged panels promptly to maintain insulation and protection.
- Vent and Door: Ensure the roof vent and door mechanisms operate smoothly. Lubricate hinges if necessary.
