When I'm drying my beans indoors, post harvest, I 'wick them' for a time, to speed and ensure dryness, by insulating the seeds with layers of paper products. I learnt that from my dad, who worked in the bush for many years, and often had wet boots in winter by days' end. All the men stuffed crumpled paper in their boots to pull the wet out through the night. They heated the cabins with fire, which I'm sure helped, but he said the boots were always dried by morning from the wicking action of the paper in them. But I've heard horror stories of people sealing up their seeds in jars and plastic containers, only to find mould on them thereafter. It's tricky, because sometimes a bean will look dry, but it really is not.
