I shoot for 60 degrees and 60% RH in my drying area. So iff the temperature drops to 55 and the RH drops to 55, is that good or bad? I have this theory that the sum of the temp and RH should be 120-130...just a dumb index idea. I know hot and dry is bad for hanging, but cold and dry? When it's cold, dry air is dryer than when it's warm, right? RELATIVE humidity? Does that accelerate drying? Somebody out there can science this one!
