Grow Gadgets Plug-In Fan Speed Controller Dimmer

Dial Your Extraction Up or Down in Seconds

A no-nonsense manual speed controller for growers running a single extractor fan. Plug the fan into the dimmer, the dimmer into the mains, then use the dial to set your airflow rate: no wiring, no menus, no controller box on the wall. In hot weather wind the speed up so warm air is pushed out with more urgency; in the colder months wind it back to hold heat in the space, or stop the airflow altogether. It handles a maximum load of 230V/300W and suits one small fan up to 8 inches (200mm). It is not responsive to environmental conditions, so it suits beginners and budget builds.

Key Benefits

• Manual dial control over extraction rate, adjustable in seconds
• 230V/300W maximum load, ample for a single tent extractor
• Suits fans up to 8in (200mm), the standard hobby grow room size
• Plug and play, no wiring or installation needed
• Summer and winter use: more airflow in the heat, less when holding warmth

Is Your Fan Stuck on Full Blast?

An extractor running flat out all year strips heat and humidity from the tent in winter and roars while it does it. Too little airflow gives stale, humid air, weak stems and slow growth; too much and the room dries out and temperatures crash overnight. Trimming the speed by hand lets you settle on airflow that keeps humidity sensible and the canopy moving.

How to Use

• Plug in: connect the fan into the dimmer, then the dimmer into a mains socket
• Check the load: keep total draw within 230V/300W and one fan of 8in/200mm or smaller
• Set by feel: turn the dial until the tent walls pull in slightly and temperature holds
• Warm weather: increase speed to shift heat faster
• Cold weather: reduce speed to retain warmth, watching humidity
