Every customer would like to run their fan on a controller. Sometimes a fan has a built in controller, but most of the time they are sold separately. Many fans already have a built in speed switch, varying from 2 – 4 speeds. AC fans (and also AC controllers) are also Amperage dependant. In other words: the number of fans you can run is limited. In addition to this, you can’t exceed the maximum amperage stated on the controller.

This is not an ideal situation. You want to control the full spectrum from 0 to 100%, since no workspace is the same. Those variables demand extra control and settings so you have more flexibility. Day and night settings for example, or more control on the temperature and humidity; elements that help you optimize the growth and bloom. In short, a perfect end result.
