Heating Incubators?

I have been making an incubator. It will basically be a wooden box insulated with styrofoam inside. It is about 3ft high and 1 1/2 ft wide and 2 ft long. I would like it to be able to stay at a constant 87f. What should I heat it with: heat tape heat panels or...

Heat tape is the way to go. Heat panels do not heat the air only surfaces so they wouldn't work in an incubator.
