This is my mini fridge incubator that I am working on. I have a light in there not sure if I need it. It will turn on and off with a switch so it will not be on all the time. The wattage is low on it also as to not cause to much heat when on. How many of you have a light in their incubator's and use it? I also used 3 feet of 11" flexwatt to heat it. I was scared 2 ft would not be enough but I don't know if 3ft is too much. Thoughts on that? I also added a fan on the bottom. Do you think it is needed in such a small space? I figured it couldn't hurt to add one. The only thing I am worried about is the fan blowing all the heat out when I open the door. I figured I would shut it off before I open the door. Thoughts on the fan? The space next to the fan at the bottom of the incubator is for the bottled waters I am going to put in there. Thanks for the opinions
