Food Storage

So, after searching for a chart that I once had (it's of course missing), I know that my 3-gallon buckets will hold 48 cups of food, approximately 18 lbs. of any one item. It obviously varies. Also, apparently a year's supply of food for ONE person is 25 gallons of beans, rice, flour, etc. That is kinda crazy when you think about it. I can't imagine the storage for that much food! The question is: do I start hoarding now, and hiding it in my closet, or do I wait until we move and have proper storage?
