OK. My new Rubbermaid bin has been working for a couple of weeks with no problems. This week my new garage addition will be completed. The worms will be going into the garage. The garage is heated, but the minimum thermostat setting will be based primarily on the needs of my worms. The worms are EFs. I realize there is a tradeoff here between worm activity and the cost of heating the space. If it were you, what would you consider to be a reasonable minimum temperature setting? I'm thinking around 60 deg F. is doable.
