I've wondered what can be done about this. Convection needs height to
really get going so I wonder if some less permeable layer laid
horizontally between the layers of bales might reduce it some.
Obviously you don't want it totally impermeable to water vapour or
liquid, and you want it cheap. So for a completely off the wall idea,
how does laying sheets of old newspaper on top of each row of bales
sound? They'll get holed a bit but that shouldn't matter too much.
