Trying to rehydrate

I moved about 7 months ago and the box containing my humidor was lost in the move. 2 weeks ago, it showed up on my doorstep. Needless to say, the cigars are pretty dry, but I would really like to salvage them as about a dozen of them were a gift from my grandfather before he passed.

The humidor is small, all wood. There are maybe 20 cigars in total. I purchased a new Drymistat Humidifier tube and a Caliber III Thermometer Hygrometer. It has been a week and I can't get the humidity above 62. The average temp in my home is 75, the high gets close to 80 during the day (in South Florida and running the A/C all day would make me go broke). I realize that I don't want to much humidity in there right now as I slowly rehydrate, but I figured the Drymistat would have raised the humidity close to 70 by now.

Any suggestions on the best next steps? Thanks in advance!
