I have a separate building to over winter the gang. I tried it in the house and in my workshop and the couldn't control the humidity enough. They come in in Oct and are heated to 75* till jan when the heaters are slowly turned down and then off by the end of March. This takes them down to low to mid 60*'s.
They'll go back out in about 2 weeks and the pond temp will be up to the holding tank temps...weather permiting.
