Active Air Climate Control Products for Indoor Growing
Active Air is Hydrofarm’s line of indoor growing climate control equipment — fans, dehumidifiers, humidifiers, air conditioners, and CO2 devices designed to provide accessible, reliable environmental control for home and small commercial growing operations at practical price points.
Active Air Fans, Dehumidifiers & Humidifiers
The Active Air product range covers the core environmental control needs of most indoor growing setups. Active Air inline fans are available in 4-inch through 8-inch configurations for exhaust and intake ventilation in grow rooms and tents. Active Air wall mount and clip-on circulation fans provide canopy-level airflow in multiple sizes. Active Air dehumidifiers range from 30 to 60 pints per day — sized for hobby grow rooms and smaller commercial spaces where Quest or larger commercial units would be over-specified. Active Air humidifiers provide moisture addition during propagation and early vegetative growth when ambient humidity needs supplementation. Active Air CO2 systems include burners and controllers for grow room CO2 enrichment programs.
Active Air as a System
The Active Air product ecosystem is designed to work together — their fans, filters, controllers, and climate equipment are sized and specified to be compatible, making it straightforward to build a complete environmental control system from a single product family. This simplifies setup for growers who want everything to work together without compatibility research.
