I saw a product called "humidipack" which is supposed to absorb and release moisture to keep a relative humidity of 45% inside a guitar case. it's claimed that this product is recommended by taylor. does it work? is there anything similar but better? it seems one major problem with this idea is that it can't release water if there is simply no more to release, and the opposite is true. Maintaining proper humidity is such a pain in the neck. and, maintaining 72 degrees at 45 relative humidity in the living area at all times is not an option. any thoughts? thanks.
