Probe in Incubator

[Twisted Reptiles]

good question. Thats the main thing I want know. Cause don't you need the temp inside the box to be 88-90, and not the outside of the box?

As long as your incubator is well insulated and the heat is evenly distrubuted, there should be little or no variance between the ambient temps inside the incubator and within the egg box.

That being said, if you need reassurance, use multiple thermometers.
