The area farthest southward/front will receive the least amount of sunlight, thus a perfect place for a cold sink... especially if there is a slight downward slope towards it. I believe Mike had stated something about keeping rabbits? within the cold sink area (for the ongoing CO2), but that just seems cruel and messed up to me. I was thinking it would likely make a great area (inside the cold sink) to store onions, potatoes, etc.... or even some canned good jars, by making a pallet like raised walkway just above, made of small sections that could be removed to reach in for these as needed.
