I will be using a Versalab 11x14 print washer. My darkroom water heater is only 6 gallon, and currently the water is coming out in the low 50s here in Maine. I have a thermostatic mixer so I can probably get 68 degrees for a while, but I doubt I could maintain it for 30 minutes. Especially if I have to fill the washer first. Any idea how long I should extend a wash to compensate for the low temps?
