I'm developing 4x5 film in a Paterson System 4 tank with Caffenol CL(CS) doing a cold start at 59F, stand development. How concerned should I be about temperature drift? Currently, the ambient temp in my darkroom is about 66F and after 10 mins of stand development, the coffee mixture was 61F. During the summer months (which is much of the year where I live), the ambient temp in the darkroom hovers around 82F. It seems logical that the caffenol temp over the course of a stand development duration will rise faster and to a warmer temp during the hot months of the year. During the hot months, should I use a water bath to keep the caffenol temp close to what I'm seeing now?
