1000W Vortex Thermostatic Fan Speed Controller - Automatic Climate Control
Best for: growers who want their extraction fan to respond automatically to temperature instead of running flat-out or needing constant manual adjustment.
Our thoughts
Running a fan at full speed around the clock is noisy and wastes energy when your tent doesn't actually need that much airflow. This does the thinking for you - set a temperature, plug your fan in, and it ramps up and down automatically. Performs consistently when you need it to.
The Vortex 1000W Thermostatic Fan Speed Controller takes manual guesswork out of grow room climate control. It monitors ambient temperature through a built-in probe and automatically adjusts your fan's speed to match - as the room heats up, the fan speeds up; as it cools down, the fan eases off, saving energy and cutting noise compared to running flat-out constantly.
It controls fans rated up to 1000W, which covers most mid-to-large inline extraction fans used in grow tents and grow rooms. It comes with a standard 3-pin plug and socket arrangement, so there's no need for extra adapters - you plug the controller into the mains, and plug your fan into the controller.
How it compares
Fan control generally means either a fixed-speed dimmer, a thermostat, or a combined unit like this one.
- Combines both thermostatic control and a dimmer function in one unit, rather than needing separate speed and temperature controllers
- Automatic temperature-based adjustment means less manual fiddling than a standalone dimmer, which only ever runs at whatever speed you last set it to
- 1000W rating covers the vast majority of mid-to-large inline fans, so it's a good match if you're not running an oversized commercial-scale extraction setup
A sensible, set-and-forget option if you want your fan responding to actual conditions rather than running at one fixed speed all day.
Usage guidance
Setup
Plug the controller into the mains, plug your fan into the controller's socket, and position the temperature probe somewhere representative of your growing area - not right next to the fan or a heat source.
Setting temperature
Turn the dial to your target temperature. The controller will hold the fan at a lower speed until the room approaches that point, then ramp up as needed.
Fine-tuning with the dimmer
Use the dimmer function to cap maximum fan speed if you need to control noise levels even during warmer periods, rather than letting the fan run at full pelt every time.
Checking fan compatibility
Confirm your fan's wattage is at or under 1000W before connecting - running a larger fan through this controller isn't supported.
Technical specifications
- Brand: Vortex
- Maximum fan load: 1000W
- Control type: thermostatic with dimmer function
- Temperature sensing: built-in probe
- Connection: standard 3-pin plug and socket, no adapters required
- Use case: grow tents and grow rooms, mid-to-large inline extraction fans
Who this is for
- Growers running a single inline extraction fan who want automatic, hands-off control
- Anyone trying to cut down on constant temperature-driven manual adjustments
- Growers wanting quieter running during cooler parts of the day or night
- Grow rooms and tents using fans rated up to 1000W
Our take
This is a straightforward way to take one more manual job off your plate. Set the temperature you want, plug your fan in, and let the controller handle the rest, with the dimmer there if you need extra control over noise or speed.
Worth picking up if you want equipment you can rely on.
