Bingo!
But, make sure the wood you buy is kiln dried. Try to buy it locally as a matter of quality control. You may also be able to get it planed and drum sanded as part of the purchase. Go with 1/4" solid Spanish cedar, NOT veneer over plywood or press/particle board.
The reason Spanish cedar is used, aside from imparting some fragrance and flavor, is that it resists mold in high humidity. other certain types of would can be used. i think one is from the mahogany family.
Spanish cedar dust is an irritant and may be either carcinogenic or cause pulmonary disease. Make certain to wear a mask and goggles when cutting and sanding it.
Rip out the shelves and replace them with slotted or drilled out shelves that will not impair air circulation.
Mount an electric outlet inside for you humidification device(s) and a fan or two, and possibly some illumination.
If the interior finish has any fragrance, I would consider sanding it off on the inside.
If the outside needs to be refinished, remove the finish manually, not with chemicals. If it needs to be stained or painted, use only water-based products,which have far less volatility. Consider food grade quality, if necessary.
You may wish to consider placing a simple, inexpensive vapor barrier behind the Spanish cedar lining to make the box very close to airtight.
How will you regulate the temperature?
I hope you love it!
