After reading all of the replies, I still have one concern - if your grain is being purchased after already sitting in a humid climate such as the Gulf Coast, how do you dry out the grain enough to store it long-term in a Rubbermaid container or bucket? The house is kept below 70 (don't ask), so temp is not a problem, but humidity is over 80% here nearly all year round.
well, I live in South Florida, so my humidity is easily as bad as yours. I generally keep around 150-200lbs of grain inside the house(74-76df), under my stairs, at any given time, stored in bakery buckets and some Homer buckets, and a few dog food bins. I have never, ever had a problem, even using some specialty grains over a year after purchase.
the reason I was posting all the questions above is for the 500lbs of grain that is coming today, and storing that
in my in-laws garage...
