I always have. But I don't know why?
It is just that I have always had some one-gallon brown jugs around so I used'em.
My neighbor spray painted some clorox jugs and that is what he uses. but he uses other developers too, not just Diafine.
In all the years I have used Diafine, this question never really came up. Most everyone I knew that used it were photographers anyway and had brown jugs around.
