I use one of them in each safe/gun cabinet and I keep my home around 35-40% humidity. So far so good. Temperature in warm weather is 70 degrees and winter about the same.So I'm running a Lockdown puck that keeps track of my safe opening, closing, temp and humidity and it got me thinking.
I'm usually at 30% humidity at 72 degrees inside. From. What I've read thats pretty good. Is there a downfall to getting the humidity lower by adding desiccant packs?
