It will help if you mention where you live. Which continent? Latitude? Climate? What sort of relative humidity and temperatures are typical in the area in which you'd store your gear? Do you frequently bring cold (air conditioned, or chilled outside) gear into a humid environment that will condense moisture onto/into the gear?
Do tell! That will help with advice from folks who live in similar circumstances.
Me? I live in the US, in the mid-Atlantic region. Humid in the summer, but dry in the winter. Climate controlled residence. I've got camera gear that's decades old, and never a sign of fungus, corrosion, etc. My gear lives in the bag, or on the shelf, or sometimes in a Peli case, but never in a situation that's artificially dry. I do kee a sealed bag of dessicant packets for situations where I might need to throw gear into a case after using it in damp circumstances. But that's a very short-term measure.
