Run it flat out and you strip heat and humidity even when the room is already cool, and live with the noise; wind it down manually and the room overheats the moment lights and outside temperatures climb. Either way plants sit through swings that slow growth. A thermostat keeps a floor of constant airflow through the canopy and adds extraction only when heat needs removing.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cp\u003ePlug your intake and extraction fans into the controller, then set the temperature threshold and minimum fan speed on the dials. Position the sensor at canopy height, away from the lamp and out of the intake stream, so it reads what the plants experience. Set the minimum speed just high enough to keep air constantly moving; the controller ramps up only when extra cooling is needed.\u003c\/p\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Fan speed controller with thermostat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Adjusts fan speed based on temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan control:\u003c\/strong\u003e Twin fan, intake and extraction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e Temperature dial and minimum speed dial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor:\u003c\/strong\u003e Remote temperature probe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Grow tents and grow rooms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Vortex","offers":[{"title":"Default Title","offer_id":53445792203018,"sku":null,"price":74.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/VortexTwinSpeedThermostaticFanSpeedController.webp?v=1785295008","url":"https:\/\/hydrocropshop.co.uk\/products\/vortex-twin-speed-thermostatic-fan-speed-controller","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
