Setup and Assembly
Carefully unpack all components and verify against the packing list. Assembly typically involves constructing the frame, attaching the tent cover, and integrating the humidity and air exchange systems.
- Frame Assembly: Assemble the metal frame according to the included diagrams. Ensure all poles are securely connected.
- Tent Cover Installation: Carefully slide the clear vinyl tent cover over the assembled frame. Exercise caution to avoid tearing the material.
- Shelf Installation: Place the 5 reinforced racks onto the frame at desired heights.
- Humidifier Placement: Position the Myco-Mister II humidifier outside the tent, ensuring it is on a stable, level surface.
- Duct Connection: Connect the humidifier's output duct to the designated port on the tent cover. Secure the connection to prevent humidity leaks.
- FAE Fan Setup: Install the Fresh Air Exchange (FAE) fan. Connect its ducting to the appropriate tent port.
- Spore Floor Tray: Place the "Spore Floor" bottom tray inside the tent to collect any runoff.

Operating Instructions
The BoomRoom II is designed for automated environmental control. Proper operation involves setting the humidity and managing fresh air exchange.
Humidity Control (Myco-Mister II)
- Fill the Myco-Mister II reservoir with distilled water.
- Connect the humidifier to a power source.
- Adjust the dial on the humidifier to achieve the desired relative humidity (RH) level, typically 90%+ for mushroom pinning. Monitor the RH inside the tent using a hygrometer (not included).
Fresh Air Exchange (FAE)
- Connect the FAE fan to a power source.
- The FAE fan cycles out stale CO2, which is crucial for proper mushroom development. Operate the fan periodically or continuously as required by your specific mushroom species.
- The system is designed to run with negative pressure, helping to filter spores and maintain a clean environment.

- Humidifier Cleaning: Clean the Myco-Mister II regularly to prevent mineral buildup and ensure efficient operation. Follow the humidifier's specific cleaning instructions.
- Tent Cleaning: Wipe down the interior and exterior of the tent cover with a mild disinfectant solution as needed to prevent contamination.
- Spore Floor Tray: Empty and clean the "Spore Floor" bottom tray regularly to manage runoff and prevent spore accumulation.
- Filter Replacement: Check and replace any air filters associated with the FAE system as recommended by the manufacturer.
Troubleshooting
This section addresses common issues you might encounter with your BoomRoom II.
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Humidity in Tent | Humidifier reservoir empty, humidifier malfunction, duct not sealed, FAE fan running too frequently. | Refill humidifier. Check humidifier operation. Ensure all duct connections are secure. Adjust FAE fan timer/frequency. |
| Excessive Condensation | Insufficient FAE, humidifier setting too high, ambient temperature fluctuations. | Increase FAE fan frequency or duration. Lower humidifier setting slightly. Ensure stable room temperature. |
| Poor Mushroom Growth / Leggy Stems | Insufficient fresh air exchange (high CO2 levels). | Increase FAE fan operation. Ensure FAE fan is functioning correctly. |
| Tent Cover Damage (e.g., tear) | Improper handling during assembly or relocation. | Use a durable repair kit for vinyl or contact North Spore support for replacement parts. Handle with care during assembly. |
