I'm doing my first swamp cooler method currently. I put the ale pale in an 18gal rubbermade bucket filled with water. I'm not adding ice, doing the tshirt, or blowing air at it though. My house temp stays around 70, and I ferment in the bathtub of one of my bathrooms. The temp doesn't get over 68 in there with the door close and exhaust fan running. The temp of the water is 65 so i think i'm good to go. I might try the tshirt and fan on the next batch, i imagine the temp would get down around 60 though. Isn't that getting to low?
