20 degrees (68 F) makes a good film development temperature, in my opinion, primarily because it's room temperature and we as darkroom technicians are likely to be comfortable at that temperature. If the development time at 20 degrees is reasonable, it is a great time to use. It may be that in warmer areas of the world, 24 might be a more convenient temperature, in which case by all means use it. I use 20 because the basement darkroom that I use is near or at that temperature all the time.
