Buying Guide
iFresh Smart Series: Ideal for users with remote control needs. It supports Bluetooth/WiFi connections to the app, allowing you to set timers and smart temperature and humidity strategies via the app, while also supporting manual speed control with a knob.
Thermostat Controller Series: Perfect for users with constant temperature/humidity requirements. You can set automatic temperature and humidity triggers through the controller.
Speed Controller Series: Suitable for most indoor growers with cooling or air purification needs. It offers high cost-performance, with simple yet stable functionality. The Duct Fan and Carbon Filter Combo is suitable for most users, but if you're a beginner or planning to expand into a completely new growing space, we highly recommend purchasing the Complete Fan Kit, which includes more accessories.
Size Guide:
For a space around 80x80cm (2x2 feet) or smaller, using a 100mm (4'') inline duct fan should be sufficient.
For spaces like 120x60cm (2x4 feet) or 100x100cm (3x3 feet), either a 100mm (4'') or 150mm (6'') inline duct fan would work.
For spaces around 120x120cm (4x4 feet) or 150x150cm (5x5 feet), you’ll need to use a 150mm (6'') inline duct fan.
If your grow space is larger than 5x5 feet, you may need at least two inline duct fans to ensure adequate airflow.
