Making a brand new humidor using a plastic air tight food container. It is about 19" tall and opens from the top. I have some ideas down the road to make some kind of shelving for easier management but for now I will just be using cigar boxes for storage. My wife asked me why I was putting the boxes in the humidor. I know the boxes can help the same way the cedar strips do but I was not able to explain about circulation when the boxes are closed. This makes me start to second guess myself. While the humidor will have the right rh the boxes insides the humidor will have enough flow to get to the right RH. Right?
