So, I have a lead on an old lab oven, which I thought could be converted to an incubator. It already has circulation, and I may be able to use the existing heating system. I would need to cut and install a window, put in a hygrometer and a humidity source. It's old, so it may need rewired. But, even if I have to redo the entire guts, I think for $30 it could still be a good deal. Does this seem doable? It's about 3 foot tall by around 2 foot wide (outside dimensions), and has 2 racks on it, which I would eventually like to replace with auto-turners.
