Sounds doable. Put the journals in a little sealed box with a tiny vent that lets some air out, but not all the moisture. Add a few silica gel packets – they’ll pull the dampness without drying the paper too much. If you want a bit more control, a low‑power dehumidifier set to a high‑humidity setting (around 50‑60%) works, but make sure it’s in a separate room so you don’t get a big draft in the box. Just keep an eye on the moisture level and replace the gel when it’s heavy. Easy to set up and won’t cost much.
