Here's an idea for your humidity problem... I just did this with my humidore the other day, b/c out in CO, it's so stinking dry that everything made of wood cracks. If your box is made out of wood, wipe down all the wood with a sopping wet sponge and make sure your box is sealed well. Your humidifier is probably working overtime to bring up the humidity and can't. Once you bring the humidity up by wetting everything down, the humidifier should easily be able to sustain it, just like a humidore.
