Non climate controlled storage - the attics

[BeckyinTX]

With the high temps that can be reached during the summer, I'd be worried about a possible decrease in vitamins in the food. Anyone know the chances of that?
Have you considered adding a solar attic fan? The research that I've been doing shows a possible temp. difference of only 5-8 deg above the ambient temp. LCAS-271

That's the way I understand about the nutrients too & it makes sense. I was thinking more along the lines of storing things like salt & sugar up there. They have no nutrients to deplete. :) I wonder how things like corn syrup, pancake syrup, & cocoa would do? They also have no nutrients to be concerned about, only consistency & flavor. I may just have to stash some up there a few years & see how it does. The sugar is packed in mylar then in buckets & it's been up there for a couple of years. I spot checked it a couple weeks ago & so far it's dry with no flavor changes. So far, so good. :) We did store our onions up there on screens & they lasted 9 months. They would've been fine but we had a hard freeze & it froze the outside layer.

Our attics all have ridge vents as well as those whirly things that pull out the hot air but it's still Texas & it's still very hot. My guess would be the attic reaches temps of 120 deg. or more with nearly 100% humidity. A solar fan might be good to have for inside the house. Not having AC will be tough!

We store non food preps in the attic. One way we store our items is the wife added 4" pedestals under bed frame legs. This hikes the bed up a bit, and allows for canned storage under the beds. Thats an average of 500 square feet of storage for each room. That gives us an additional 2000 square feet of storage. Just a thought

Most food products say "store in a cool, dry place." If some of your preps are MREs, here is a url to a chart. . Heat drastically reduces the shelf life of MREs and, my mom says canned goods as well. I suppose dry goods are not as susceptible (sugar, dried beans, etc.). I have heard of many people using under-bead storage. Seems like a great idea to me. Fortunately, I have a subterranean basement in my primary home and my BOL, max 75 degrees in summer and 45 degrees in winter.
