Basement temps are usually fairly steady all year. The worst is a fast change in temp. If you can control the humidity there should be no need to case the guitars. I havent cased my guitars in 2 years except for when going on vacation. The worst part is basements tend to be damp so the dehumidifier will need to be emptied constantly. Most of them can be connected to a hose that you can run into a sump pit. Alot of them can also pump if you need to get up and over i to a sink.
