How to set up a SMS Pro Twin Fan Grow Room Speed Controller

After plugging in your intake and extractor fans, its play time! Setting up your SMS controller could not be easier but you do need to follow a few fundamental steps to get your set up right. Firstly lets cover come do's and dont's :

  • DO NOT cover the sensors with your hands, hot or cold water trying to make the controller change speed. This will only delay your controller adjusting to its new environment.
  • DO mount the sensors inside your grow room and leave them there
  • DO NOT mount your sensors near to high heat out puts light lights and electronic equipment.
  • DO mount your sensors in a sensible position near to your plants.
  • DO NOT make large adjustments to settings as this will take longer to trim.
  • DO set the temperature at 25 degrees, min speed at 30 and max speed at 80 to start (see below diagram). Make small adjustments over the next week to trim your system.

Please remember that setting up grow rooms is more of an art and not a science and getting it right for your setup will take some time. Environments change, seasons change and so will the demands of your plants.
