HELP AND SUGGESTIONS

[Litch]

Im making a homemade cabinet incubator but I'm confused about where to position the fan to fully circulate air with heat around the areas in the incubator..please help, any suggestions on where to position the fan??

the commercial ones have the fan at the back at the top of the incubator. Heat rises... so that will help circulate the air constantly so you do not have any layers of different temperatures.
