SMS 6.5A Smart Controller

Single fan speed controller that can be used alone as a manual speed control, or add the temperature probe (available separately) to turn it into a temperature controlled version.

The temperature in your grow space will vary throughout the day/night and throughout the year, having a controller to maintain fan speed accordingly is the best way to control this.

The ideal temperature for your plants is 24-28 degrees celsius when the lights are on and a drop of around 5 degrees in the dark period, thats hard to maintain if your fans are still going full power when the lights are off and drops in temperature will occur leading to slow growth and poor yields.

Did you know temperature drops below 18 degrees during the dark period can slow the processes happening inside plant cells so much that it can take up to 48hr for them to return to normal? If your room is dropping cold night after night your plants will be permanent state of suspension which can seriously affect your growth rates to a near standstill and massively drop your yields.

Connect your ventilation fan to the sms controller and set your desired temperature, next set your minimum fan speed, we recommend a minimum fan speed of no less than 20-30% to ensure adequate air exchange still occurs. The controller will then turn your fan up once the temperature exceeds the set point.
