Setup and Assembly
Proper preparation is crucial for a smooth assembly process. Ensure you have a level site for installation and organize all parts before beginning. The BILT app provides interactive 3D instructions to guide you through each step.

Assembly Tips:
- Site Preparation: Select a level area for your greenhouse. An uneven foundation can lead to alignment issues during assembly.
- Part Organization: Unpack and organize all components, including hardware, by their labels. This will significantly reduce assembly time.
- Follow Instructions: Adhere strictly to the provided instructions, especially regarding pilot holes and component orientation. Double-check each step to avoid deconstruction.
- Squaring the Base: Ensure the base is perfectly square and maintain its squareness as you build upwards. This is critical for proper panel fitment.
- Roof Assembly: While instructions may suggest two people for lifting the roof structure, some users have found it possible to assemble the roof directly on the structure by adjusting the sequence of steps.
- Sealant Application: If applying a protective clear coat or sealant to the cedar, do so before assembly to ensure even coverage and avoid covering part labels.

Operation
Ventilation:
The greenhouse features both active and passive ventilation systems to maintain optimal growing conditions. The integrated temperature-activated exhaust fan automatically regulates internal temperature by expelling hot air when needed. Additionally, two easy-open windows allow for manual control of airflow and natural cross-pollination.

Watering System:
For convenient watering, the greenhouse includes both exterior and interior hose hook-ups. An interior hose is provided to simplify the process of watering plants from seedlings to maturity.
PowerPort:
The patented PowerPort offers three electrical outlets and three USB ports. This allows you to power various gardening accessories such as grow lights, additional fans, or other electronic tools. Ensure a suitable power source is connected to the PowerPort.

Maintenance
To ensure the longevity and optimal performance of your greenhouse, regular maintenance is recommended.
- Wood Care: The cedar wood is naturally resistant to decay. However, applying a wood sealant annually can further protect it from weathering and extend its lifespan.
- Panel Cleaning: Clean the polycarbonate panels periodically with mild soap and water to remove dirt and algae, ensuring maximum light transmission. Avoid abrasive cleaners or tools that could scratch the panels.
- Ventilation System: Regularly check the exhaust fan for debris and ensure it operates freely. Keep the windows clear of obstructions.
- Structural Integrity: Periodically inspect all fasteners and connections to ensure they remain tight. Verify that the greenhouse remains properly anchored, especially in areas prone to high winds or heavy snow.

Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Greenhouse interior is too hot/cold. | Ventilation system not operating correctly; windows closed; fan malfunction. | Check if the temperature-activated exhaust fan is powered and functioning. Ensure windows are open for passive ventilation. Clear any obstructions from the fan or window mechanisms. |
| Water leakage from roof or panels. | Improper panel installation; damaged sealant; loose connections. | Inspect panel edges and seams for gaps. Reapply silicone caulk where necessary. Ensure all screws and bolts are tightened. |
| PowerPort not functioning. | No power supply; tripped breaker; faulty connection. | Verify that the PowerPort is connected to a live electrical source. Check your home's circuit breaker. Inspect the PowerPort's wiring for any visible damage. |
| Doors or windows do not close properly. | Misalignment during assembly; warped wood; debris in tracks. | Check the squareness of the greenhouse frame. Clear any debris from door/window tracks. Adjust hinges or sliding mechanisms if possible. |
