Thunder Kat, pick yourself up a digital humidity & temp gauge. What's really popular is the Acu-Rite digital thermometer and hygrometer from Wal-mart. they're around 12 or 13 dollars right now, found in the home improvement section

Depending on your ambient humidity, you may or may not have to increase the humidity. I used to use a tank and struggled with humidity every day, and I would put a damp towel over the top of the screen.
