I've got a big 454g packet of Kodak HCA. I don't exactly have room for the 5\nUS gallons that it will produce. I've contemplated just weighing out 20 per\ncent and making 1 gallon. Is it possible to make the whole packet into a\nconcentrate similar to other manufacturers' (e.g. Agfa 4-in-1), then dilute\n1:31? Thx.
