Planning a garage

[k92]

I can keep the humidity to below 30% at any given time in my garage. I put down some plastic on the slab,then carpet over that. My walls have r-13 and ceiling r-19,both are drywalled.No fans or a/c and it's always much cooler inside that out during the summer.During the winter I have a Modine garage heater and keep the temp at 50 except when I'm out there.I have not had any flash rust issues and have had freshly blasted parts laying around for weeks at a time without any problems.
