FAQs
What size grow tent is this 4" kit suitable for?
This 4" kit is ideal for smaller grow tents, typically up to a 3' x 3' tent. It ensures sufficient air exchange to maintain an optimal environment for your plants.
How does the Controller 69 automate my ventilation?
The Controller 69 includes a sensor probe to monitor temperature and humidity. You can set target levels, and the controller will automatically adjust the fan's speed to maintain your desired climate, ramp up during lights on, or turn off when not needed.
How often should I replace the carbon filter?
For optimal performance, we recommend replacing the carbon filter every 12-18 months, depending on usage and the level of odors. The filter flange is reversible to extend its lifespan.
Can I use this kit for air intake instead of exhaust?
Yes, absolutely. The entire system is versatile and can be configured to pull fresh air into your grow space or exhaust stale, hot air out, depending on your specific ventilation needs.
Is the fan noisy?
No, the CLOUDLINE fan is engineered for quiet operation. It uses an energy-efficient EC motor mounted with dual ball bearings, producing only 29 dBA at full speed, which is comparable to a soft whisper.
How do I get the best results with this kit?
Proper installation is key. Ensure all connections are airtight using the included clamps. For a comprehensive overview and tips, check out our in-depth guide on AC Infinity kits to maximize your setup's efficiency.
