With out a cabinet, it depends on the temp. and humidity for the time of the year, where you live. You just have to watch it and boil, when it is time. It may only take a couple hours in the summer, and all day in the summer.

Last summer I needed no help in the garage in N. Carolina. Come fall and winter, I had to use the cabinet. To keep it from getting to extreme in there, I've placed a heating pad from the pharmacy on the floor of the locker, with a 9"x9" non-stick cake pan on top of it. Not to fast, not too aggressive, but a good healthy rusting nonetheless.
