Humidor Setup

A humidor puts controlled moisture into a bent, curved, or warped card so it can be pressed flat, then lets that moisture back out during drying. It is the safest of the three hydration levels (hydro pump and Humidity Storm are the other two): the card never touches liquid, it cannot be oversaturated, and the texture change it causes is far easier to manage than a storm. The trade-off is time. A humidor is slow.

This page covers choosing a humidor, setting it up, loading cards, how long to leave them, and what to do when the card comes out. The full process is humidify, prep, press, dry, check.
