I see frequent references to humidity problems in various posts. I have a solution that has worked well for me. I use the New Zealand sphagnum moss that you see on some suppliers websites. Get one of those mesh bags that fruit or other things come in at the grocery store. Tie up a ball of the sphagnum moss in the mesh bag about the size of a tennis ball and wet it thoroughly. It will hold a lot of water and will maintain the humidity for three or four days. A lot easier than misting or whatever. I have used one of these for six months and have seen no signs of mold, but it would be simple to change the moss if mold occurred.
