I just got a new super large safe and I have it in my garage that is not temperature controlled. I have two golden rods installed in the bottom back wall and I put two Eva-Dry E-500 Dehumidifer on the top shelve. Do you think this is enough I live in central Texas and we have humid days. What should I do in the winter do you think I should do something to keep the temperature up inside the safe? and what would I use?
