This neat and tidy little fan controller from SMS monitors the temperature in either your grow room or tent and adjusts the running speed of your fan automatically to maintain the temp. selected on the control unit. You plug the unit into your power socket and then plug your exhaust fan into the unit, plug in the external temperature probe (sold separately) and place it in your grow space where it'll give you an average reading, then set the temperature you'd like to maintain in your room. It's that easy.
