temperature management

Seed Germination/Early Growth Chamber

We plugged the unit in on March 3, 2015. Some of the issues we have noticed in the first few days of operation are extremely high temperatures and humidity levels. When removing the old freezer hardware I left the thermostat wiring in place, I'm thinking I can use this wiring to set up a way for the unit to be self regulating, I'm just not sure how to do this. We started out with an aquarium pump in a pan of water to keep the heat/humidity up, but this proved to be too much. We took the aquarium heater/pan out and put a 60W incandescent bulb in the unit to provide the heat source.
