Buying Guide |
1. 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.
2. Thermostat Controller Series:
Perfect for users with constant temperature/humidity requirements. You can set automatic temperature and humidity triggers through the controller.
3. 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.
4. Size Guide:
Take a space with a height of around 1.8 meters (6 feet) as an example:
1)For a space around 80x80cm (2x2 feet) or smaller, using a 100mm (4'') inline duct fan should be sufficient.
2)For spaces like 120x60cm (2x4 feet) or 100x100cm (3x3 feet), either a 100mm (4'') or 150mm (6'') inline duct fan would work.
3)For spaces around 120x120cm (4x4 feet) or 150x150cm (5x5 feet), you’ll need to use a 150mm (6'') inline duct fan.
These are some common grow tent space dimensions. If your grow space is larger than 5x5 feet, you may need at least two inline duct fans to ensure adequate airflow. |
