Or you could place the towel on the
exterior of the bin on the offending side.
(Gee, I don't think you can think more outside the box than that!
)
I'd also try a second thermometer. It's hard believe that temperature could vary that much in a little veggie bin.
For plant materials, I actually like that my fridge is
a little inconsistent. All plants that use a cold dormancy system where natural temps go to freezing or below have some sort of antifreeze inherent in them. Species that have a tendency to start growing in the fridge when "their time is up" would benefit with 31F.
