View Full Version : atmospheric controls in my dr120 darkroom

07-18-2008, 08:13 AM
I currently use one Speedster Fan Speed Controller(SFSC) to control the 6" vortex exhaust and another SFSC to control the 4" vortex intake fan. I have no interest in using co2 at the moment, only to control temp and humidity.

I would like to use a more automated solution without paying out the nose. Is the Green Air H/C 7 something that would help my situation?
