SMS Pro 4.5a Twin Fan Controller

The SMS Pro 4.5a Twin Fan controller is the perfect addition to your grow room. Unlike other controllers that shut off a fan when the desired temperature is reached, the SMS Pro Twin will calculate the required running speed of the fan to maintain the temperature set. The SMS Pro Twin Fan controller functions in the same way as the original SMS Twin, however it has the added benefit of removing excess humidity form the grow room during the lights off period.
