sure sure...What kind of bedding are you using?

Find a wal-mart and around the outdoor section (normally around the paint section), pick yourself up an acurite digital thermometer. It has a probe that you can put on the warm end, and then put the thermometer itself on the cool end. It also measures humidity....it's a great little product for like 12 bucks...I'd say 90% of ppl use them. They're excellent for a quick look to see how warm/cool/humid your tank is.
