Complete Grow Room Climate Control System Upgrade your grow environment with a complete ventilation and climate management solution. The Mars Hydro iFresh Smart Ventilation Bundle combines a powerful 4" iFresh inline fan, refillable carbon filter, 6" clip fan, and iControl smart controller to deliver efficient airflow, advanced odor control, internal air circulation, and smart automation — all in one integrated system. Powerful Ventilation with Efficient Air Exchange Powered by an energy-efficient EC motor, the 4" iFresh inline fan delivers up to 205 CFM airflow to efficiently exchange air, remove excess heat and humidity, and help maintain a more stable grow room environment. Designed for reliable performance, its durable construction with an IP44-rated water-resistant housing ensures consistent operation in demanding indoor growing conditions. High-Efficiency Odor Filtration with Refillable Carbon Core The high-quality activated carbon filter effectively captures unwanted odors, smoke, and VOCs from your grow space, helping maintain cleaner and fresher air. Its refillable design allows you to replace the carbon core instead of the entire filter, extending filter lifespan and reducing long-term maintenance costs. Balanced Airflow with Smart Climate Automation The included 6" clip fan enhances internal air circulation, reducing stagnant zones and hot spots while promoting a more uniform growing environment. Connected with the iControl smart controller and MarsPro App, the ventilation system allows growers to monitor temperature, humidity, and lighting conditions, set schedules, and automatically adjust airflow based on real-time environmental changes. All-in-One Grow Room Air Management Solution Unlike traditional ventilation setups that require multiple separate components and manual adjustments, the Mars Hydro iFresh Smart Ventilation Bundle provides everything needed to manage your grow room atmosphere — from air exchange and odor filtration to circulation and intelligent climate control. Designed for growers seeking a cleaner, more stable, and easier-to-manage environment, this complete system helps maintain optimal airflow, improve climate consistency, and simplify daily grow room management.
