I am considering building a shelf type layout in my garage. It is an attached garage, approximately 25 feet by 20 feet. It is not climate controlled. I live in Houston, Texas. It doesn't get all that hot in the summer inside the garage, not that cold in the winter, but the area would definitely see some fairly large temperature variations through the year. I'm guessing it could get down to the mid 40s in the winter and maybe 90 degrees in the summer. does anyone have experience with something like this? Would there be problems with the temperatur range? Humidity? Any other thoughts?
