I'm kind of interested in a FTSS to control my ferm temps. I currently roll my conical into a ferm chamber I built and cool with a window unit. I'm at the point where I need to built it better (and make it look nicer) or do something different. One thing that's always bothered me about the FTSS was the coil and adding another thing to clean with a lot of nooks and crannies. Has it been a problem for anyone?
