A complete grow tent ventilation and air filtration kit that includes all the essential inline components needed to efficiently ventilate and control the environment inside your grow space. Designed to simplify your setup, this all-in-one package removes the hassle and guesswork of sourcing compatible ventilation parts separately, making it ideal for both beginner and experienced growers.
At the heart of the kit is the powerful CLOUDLINE inline duct fan, engineered to deliver high airflow performance with exceptionally quiet operation. The system is powered by an advanced AI smart controller, offering intelligent self-automating climate control with predictive environmental adjustments and precise fan speed output for optimal growing conditions.
Also included is a premium rust-resistant carbon filter with a sleek gunmetal finish, packed with high-quality Australian virgin activated charcoal to effectively eliminate odours and prevent unwanted smells from escaping your grow tent or grow room.
The ventilation system is connected using durable flexible ducting constructed with four protective layers for improved strength, longevity, and efficient airflow direction. Additional accessories such as duct clamps, prefilter cloths, rope clip hangers, and hanging straps are included for a complete and easy installation.
Part of the UIS™ smart growing platform, this grow tent ventilation kit is fully compatible with other UIS™ devices and controllers, allowing you to create a fully integrated and automated grow room environment.
Intelligent Programming
CONTROLLER AI+ observes your grow space, pairing with the inline fan to make environmental adjustments and ensure its stability. Going beyond on/off triggering and timer programming, it is always learning, analyzing previous results to avoid over or undershooting output levels and better optimize your climate. Connect this controller to the AC Infinity app to select between two AI inputs for quick AI-generated presets that adjust automatically or fine-tuned control for greater customization. You can also get access to helpful grow guides, recipes, articles, video tutorials, and chatbot assistance that will equip you with the knowledge to improve how you grow.
Quiet and Energy-Efficient Design
The included CLOUDLINE Series inline fan features a PWM-controlled EC motor, enabling smooth operation at low RPM speeds with no additional heat or noise. It achieves high-performance airflow fit for grow tents thanks to its mixed-flow design and its use of stator blades and hydrodynamic wind circles. Dual ball bearings give this inline fan a 67,000-hour lifespan, which is backed by its IP-44 sealing that resists dust and splashing liquids.
Premium Grade Carbon
The duct carbon filter effectively blocks unwanted odours and chemicals using its bed of premium Australian charcoal. Featuring a 1200+ IAV rating, the activated carbon supports clean airflow more efficiently, thanks to its increased adsorption rate and extended life rating. The filter’s durable steel mesh body is protected by a powder-coated gunmetal finish to defend against rust and corrosion in high-humidity growing environments.
