Chris,

Birch is a wood that is relatively non-acidic so it would be a safer
choice than oak (highly acidic). Allowing for ventilation would help
prevent the buildup of volatile organic compounds such as formic and
acetic acids. The silica gel would help absorb excess moisture thereby
lessening the risk of Bynesian Decay. Don't forget that silica gel can
become "saturated" with water and needs to be replaced or regenerated
periodically. Not sure where the sodium bicarbonate comes into play except
possibly as a deodorizer. Sounds like you have a nice set-up.
