Why customers choose PatioZora Garden

Introducing the VIVOSUN T4 4-Inch Inline Duct Fan paired with the E42A+ WiFi Controller. This integrated system blends powerful airflow with smart, app-driven management to help you cultivate with confidence in tents, greenhouses, and other grow spaces.

Engineered for efficiency, the EC motor offers PWM control, delivering robust 210 CFM ventilation while staying quiet—down to about 28 dB. The mixed-flow design helps move air across larger distances, creating steadier air exchange without harsh noise or hotspots.

Smart climate monitoring at a glance

The included temperature and humidity probe streams real-time data to your GrowHub app. You can view inside and outside conditions, track humidity trends, and calculate Vapor Pressure Deficit (VPD) to better gauge plant needs. All data syncs to your dashboard for quick reference.

  • Unified Smart Control: Manage multiple compatible devices through GrowHub E42A+ for a simplified growth routine.
  • Real-time climate data: Temperature, humidity, and VPD insights accessible from the app.
  • Automated schedules: Seedling, vegetative, flowering stages with preset light, fan, and airflow settings.

Automation meets versatility

  • Smart auto-triggers react to temperature or humidity thresholds to optimize airflow.
  • Quiet, energy-efficient performance: 210 CFM with an EC motor and PWM control.
  • Versatile use: Ideal for tents, greenhouses, hydroponics, attics, and other ducted spaces.

Easy setup and ecosystem

  • Two integrated ring anchors support quick, secure hanging in multiple orientations.
  • Remote control via Wi-Fi enables monitoring and adjustments from anywhere.
  • Complete ecosystem: a reliable foundation for growers of all levels with compatible gear.

Note: This system is designed to help you manage environmental variables more effectively; outcomes depend on setup, space, and cultivation goals.
