I have wonderful news; my wife is letting me move the flow through bin inside. It is currently in a cold porch and hasn't done much since autumn. The worms are still alive and the bin has been anywhere between partially frozen to cold for the last 4 months.
Ever since we moved to western PA to a one bedroom apt, we didn't have the room and she was weary about having the worms inside. Planting season is getting near and I have a dormant bin; something had to change. I convinced her to make it into a piece of corner furniture. covered in a table cloth and a table top in the living room with a plant and picture on top. I can't wait to see it come alive again when I bring it in.
