I put my tobacco in a food storage container. I make a digit in the center, put in a 1oz container of distilled water uncovered. I put the cover on the container on a seed starter warming mat. I leave the mat on for short periods, one I see a little humidity inside. I check on the blend daily until it gets to my liking. Hope this helps.
Years ago, before bulk barns, we cured tobacco on sticks. After curing we had to open the barn doors during the night to let the leaves obtain some moisture and become pliable so they didn't crumble while unloading the barn and hauling to the pack house. That's how I handle dry pipe tobacco. I pour the crunchy tobacco into my wife's biscuit pan and place it on the porch overnight. By early next morning, if pinched between the fingers, it will hold together and be soft. I just place it in a mason jar and seal it up. This works because the tobacco will only absorb the moisture amount it needs and is never introduced to liquid All that's left is washing biscuit pan and slipping it back in the kitchen before she's any the wiser.
