I am in the final stages of setting up my incubator, a converted double door fridge.
I am about to install the two fans. One at the top rear right hand side, and one at the bottom front left hand side.
Now here is the question, do I set both to blow, or one to blow and one to suck.
I want the best possible air circulation.

Oh, I have cut away the partition between the top and bottom portions of the fridge.
So it is in effect one big fridge.
