I live in PA, and my darkroom is in my basement, so this time of year it is about 60 degrees down there. When I process my film I warm the solutions up to 68 degrees, but by the end of development they are usually a degree or two cooler. How important is constant temperature? Should I buy a karosine heater to warm my darkroom up to around 70 when I know I'm gonna be down there? That way the solutions won't cool during use. Same for printing. Thanks
