Wow how did you find that deal?SFV Kush broke ground too. 3 up / 3 to go. I did get the Saturn 4 to work the way I wanted. Had to re-read the manual because I thought it said you could use an exhaust fan for cooling. I ran the whole tent all day yesterday & fan & humidifier shut off & came on several times. I think the RH knob on it is off by 10% or my Accurite Temp / Humidity Monitor is... One of the 2 are off. I have to put the Saturn 4 on 80% to get a 70% RH reading on the Accurite. Not sure which is correct; but to play it safe I'll go with what I set the Saturn RH at. So I'll set the Saturn for 65 - 70% which should give me an Accurite reading of 55 - 60% which is good enough for me. The Saturn automatically increases the Humidity by 4 or 5 % above what you set it for before it shuts off & kicks on at 3% under what you set it for. The Exhaust fan works the same way by cooling it 5 degrees lower then what you set it for. These Saturn 4's are quite useful. You can use it as an Intake or Exhaust, Humidifier or Dehumidifier, Night Circulation Fan & Co2 Controller. Got 2 of these in a bin full of equipment for $50. This Bin had over a $1000 worth of equipment so it was a steal of a deal.
