This is a good pt. I didn't realize you're having to process with the lights on. That's an unfortunate scenario. But as far as the amount of chemistry is concerned, I process in troughs with the minimum amount of chemistry for a one-shot process. For a 40x60 fb print that's less than a gallon of working dektol. I can work with one tray, but prefer two. My trays (54" X 10" X 4") take up a lot less room than a 40" x whatever size plastic drum.
