Important Safety Information
Always anchor the greenhouse securely to the ground to prevent it from tipping over in high winds or collapsing under heavy snow. Wear protective clothing and eyewear when assembling or maintaining the greenhouse to avoid injury from sharp edges or heavy components. Be aware that the greenhouse provides UV protection, but prolonged exposure to UV rays can still be harmful to skin and eyes.

Setup and Assembly
Assembly requires careful attention to instructions and is best performed by two adults. It typically takes approximately 1-2 days to complete. Ensure all parts are accounted for before beginning assembly. Some users recommend laying out all parts in numerical order for easier identification.
Preparation:
- Foundation: A solid, level foundation is crucial. While ground stakes are provided, anchoring to a concrete slab or a robust wooden base is recommended for enhanced stability against wind and snow.
- Tools: Gather necessary tools as indicated in the assembly guide.
- Part Identification: Verify all components against the parts list. Some parts may have protective films that need to be removed before assembly.
Assembly Steps:
Follow the step-by-step assembly instructions provided in the product manual. Pay close attention to diagrams and ensure correct orientation of all pieces, especially corner posts and panel rails, to avoid reassembly.

Operating Instructions
Ventilation:
The greenhouse is equipped with 2 adjustable roof vents and lockable swing doors to manage internal temperature and humidity. Open the vents and doors as needed to maintain proper air circulation and prevent overheating, especially on sunny days.

Water Management:
The built-in gutter system collects rainwater from the roof. This water can be harvested for your plants or directed away from the greenhouse foundation to prevent water damage.
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 panels.
- Frame Inspection: Periodically check the aluminum frame for any signs of damage, loose bolts, or corrosion. Tighten any loose fasteners.
- Vent and Door Operation: Ensure that roof vents and swing doors open and close smoothly. Lubricate hinges if necessary.
- Gutter System: Keep the rain gutters clear of debris to ensure efficient water flow.
Troubleshooting
- Wind Stability: Ensure the greenhouse is properly anchored. If experiencing significant movement in high winds, consider additional anchoring methods beyond the provided stakes, such as embedding posts in concrete or using heavy-duty tie-downs.
- Water Leaks: Check all panel seams and connections. Apply silicone caulking if necessary to seal any gaps.
- Assembly Difficulties: If parts are bent or misaligned, carefully straighten them if possible. Double-check the instructions for correct orientation, as some pieces may fit in multiple ways but only one is correct.
- Missing Hardware: While extra supplies are often included, if critical hardware is missing, contact customer support.
