6. Maintenance
- Tent Cleaning: Regularly wipe down the interior Mylar lining and the removable floor tray with a damp cloth to maintain reflectivity and hygiene.
- Carbon Filter: The carbon filter will eventually lose effectiveness. Replace the carbon filter sleeve or the entire filter unit as needed, typically every 6-12 months depending on usage.
- LED Light: Keep the LED light surface clean from dust and debris to ensure maximum light output. Use a soft, dry cloth.
- Grow Bags: After each grow cycle, clean and sterilize reusable grow bags or replace them to prevent disease transmission.
7. Troubleshooting
- Light Leaks: Ensure all zippers are fully closed and the tent fabric is taut. Check ducting ports for proper sealing.
- High Temperature: Increase inline fan speed, ensure exhaust is clear, or consider adding an oscillating fan inside the tent.
- High Humidity: Increase inline fan speed to exhaust more humid air. Ensure proper air circulation within the tent.
- Low Temperature/Humidity: Reduce inline fan speed, ensure intake ports are not excessively open, or consider using a small heater/humidifier if necessary.
- LED Light Not Working: Check power connections, ensure the timer is correctly set and functioning, and verify the dimmer is not set to off.
