Spider Farmer 4 Inch (10cm) Inline Exhaust Fan – 205 CFM Quiet Grow Tent Ventilation with Speed ​​Controller & RJ12

The Spider Farmer 4-Inch (10cm) Inline Exhaust Fan – 205 CFM is a powerful, quiet, and energy-efficient ventilation solution for grow tents, indoor grow rooms, and hydroponic systems. This compact yet efficient inline fan provides stable air circulation, optimal temperature control, and effective odor control in small to medium-sized grow setups.

Thanks to the updated RJ12 port, this fan is compatible with Spider Farmer GGS controllers and power strip kits. This allows you to easily manage fan speed, timers, and climate data via the Spider Farmer app for complete automation of your growing environment.

Suitable for use with 4-inch carbon filters for maximum odor control in closed indoor spaces.

Powerful & Efficient Air Displacement

With a 3000 RPM motor and 205 CFM (Cubic Feet per Minute) of airflow, this 4-inch inline fan delivers reliable and consistent air exchange. It quickly removes warm air from LED grow lights and equipment, while fresh air is drawn in for a healthy and stable indoor growing environment.

Ideal for grow tents from 60×60 cm to 100×100 cm depending on configuration.

Optimal Temperature Control

By continuously discharging warm air, this fan helps prevent heat stress. This promotes a stable growth phase, prevents growth retardation, and protects plants from damage due to overheating.

Perfect for full spectrum LED setups and compact indoor grow spaces.

Humidity Control & Mold Prevention

Constant air circulation prevents moisture buildup and stagnant air. This minimizes the risk of:

• Mold formation
• Mildew
• Condensation problems
• Root rot at high RH

A stable airflow directly contributes to stronger plants and higher yields.

Smart Control via RJ12 & App

This updated version supports smart control via GGS systems and app control.

Four working modes available:

• Set start and stop times
  
• Adjust rotation and standby speeds
  
• CO₂ device on/off control
  
• Full control via Spider Farmer app

This creates a fully automated ventilation solution within your grow tent.
