The Active Grow Walden Grow Tent 6” Ventilation Kit provides growers with the right equipment to create a clean and healthy growing environment for their plants. The 6” Ventilation Kit comes complete with an inline fan, carbon filter, ducting, ducting clamps and hydroponic hangers. The 6” Inline Fan delivers 395 CFM airflow and comes with a corded multi-speed controller, allowing growers to manually adjust the fan speed. The 6” Carbon Filter can function as either an exhaust or intake filter and removes odor, spores, pollen, chemical irritants and other airborne particles from your grow space. Each carbon filter comes with a machine-washable pre-filter. To make installation simple, the 6” Ventilation Kit includes 25’ of high-quality aluminum ducting, three stainless steel ducting clamps and four 1/8” hydroponic hangers capable of supporting up to 150 lbs per pair. The 6” Ventilation Kit is recommended for use with Active Grow 4’x4’ Walden Tents but will also fit other 4’x4’ tents with similar dimensions and characteristics.
