I don't know. That was roughly the story I got from Coles but it was at least ten years ago and I may have gotten the details a bit mixed up. They do it outdoors and they don't do it in the winter.
They didn't seem all that anxious to do it either and they did say they wait til they have a bunch of them to do.
