Bests & Worsts Reviews from Amazon

I love this setup! I use it for my exhaust in a 4x4x8 grow tent. The noise is almost nonexistent. At times, like after watering, the humidity climbs fairly high. I turn the fan on and within seconds, the number drops. It is powerful enough to clear the air in my tent within 4 seconds, and thats only on level 3! The controls are handy and the sensor is very accurate. Its very helpful to be able to set an alarm or to schedule the fan to automatically turn on when the temp or the humidity gets to a certain level. When growing sensitive plants that grow mold or burn, being able to set it and forget it, is a lifesaver. I, also, purchased the carbon filter. Installation is super easy. The way you face the arrows, will determine whether its an intake or outtake fan. I needed to buy some flexible ducting tubes and some tape, as they are not included.
