My darkroom is in my basement, and at this time of year the temperature is about 62� F. I find that if I start at 68�, the temp will drop to about 66� after eight mminutes or so. So I start at 69� and finish at 67�. I think ambient temp has a lot more to do with changes in developer temp than does any chemical reaction. How warm is your darkroom? Paul
