What is Propylene Glycol?
What exactly is the 'special solution' I'm supposed to put in my humidor, and how often should I put it in?

It's a solution of 50 percent water, 50 percent propylene glycol. You should recharge your humidification device with it every three to six months.
Propylene glycol (PG) is hygroscopic to 70 percent relative humidity, meaning its presence will keep water from evaporating beyond 70 percent. You definitely don't need to use the solution every time you fill your humidification device, but you shouldn't wait longer than six months before adding it.
Several companies sell the distilled water/PG solution pre-mixed. Another option is to buy PG at a pharmacy for about $7 a quart, then mix it yourself.
(Note: While special solution can be used in most devices, some humidifiers, such as those by Diamond Crown, use only distilled water. Refer to the manufacturer's instructions on whether it should be added or not.)
