Vortex Thermostatic Fan Speed Controller for Tents

Set Your Temperature and Let the Fan Sort Itself Out

The Vortex Thermostatic Fan Speed Controller is the no-fuss way to regulate grow room airflow. Designed to work with Vortex twin-speed fans, it switches automatically between low and high speed based on the temperature it reads in your space. Dial in the room temperature you want, the built-in probe monitors your space, and the fan steps up to high when things warm past your target and drops back to low once they settle. The housing is wall-mountable for a tidy install with the dial within reach.

Key Benefits

• Thermostatic control that switches fan speed automatically from a temperature reading
• Set and forget, dial in your ideal temperature and leave the controller to manage it
• Plugs straight into Vortex twin-speed fans with no adapters or rewiring
• Smoother, quieter operation with less noise and less wear on the fan over time

Temperature Swings and Constant Fan Fiddling

Running a fan at one fixed speed means picking your problem. Leave it on high and the room is noisy and colder than you want overnight, with humidity dropping away; leave it on low and daytime temperatures climb past the point where growth slows. Neither gives the consistency plants need, and flicking the switch twice a day is not a plan. Thermostatic control keeps airflow constant and lifts to high only when the heat is genuinely there.

How to Use

Plug your Vortex twin-speed fan into the controller and mount the unit on the wall outside the tent. Set your target room temperature with the rotary dial, then position the probe at canopy height for the most accurate reading. Keep it clear of the lamp and the intake stream so it is not reading a hot spot or a draught, then adjust the dial a degree at a time until the room holds steady.
