Take control over the air output in your grow room. The excellent SMS Fan controller allows you to manually set the speed of the fan to optimise the level of airflow. This will not only provide a better environment for your plants by controlling the humidity, but will also prolong the life of your fan and reduce your power consumption.
Simply Plug the fan into the Fan Controller and the Fan Controller into a power supply and you’re away, it really couldn’t be easier.
