the temperature was a constant 70 degrees.
That's pretty amazing. I am going to try it on a small scale here in FL. Because I know worm bins produce heat, every time I go to mess with mine the first thing I do is stick my hand in the middle of the bin. It is always quite warm to the touch. I can imagine if I made a really large pile, just how warm it would be during the winter compared to the outside.
