Are you sure buckwheat can't grow in your Ohio climate? Here in Ladakh, in the lower parts, which are probably zone 6, people harvest barley in the last week of July and follow it with buckwheat. Up where I am, which is only a little bit colder in winter and later in spring, they only grow a single round. Our summers are extremely sunny, but not very hot. For comparison, apples, apricots and pears do great up where I live, but down where they grow buckwheat as a second crop, they can also grow grapes and lame little peaches.
Maybe you could try a small garden bed of buckwheat just to see if it sets seed before fall. I use buckwheat as pancakes, with eggs and baking soda: I usually make them savory, with onions cooked in, and eaten with yogurt doctored up with herbs etc (not anybody's tradition, just my own).
