Worms and castings.We know that indoor bins do better at a higher temperature, 80 degrees F is recommended.  Worms are after all cold-blooded and will naturally be more active when they’re warm.  Keeping your bin warm helps to promote breeding and also keeps any white worm populations in check.  Here in Manitoba keeping your house warm during winter let alone a worm bin presents quite a challenge.  There are a few little things you can do to at least keep the temperature steady, if not way up to 80 degrees F. Place your bin in a position where it will benefit from radiant heat, a table on top of a heat vent for example.  The table top will retain that heat longer than the air.  Anything retains heat longer than air, especially water.  If you coil up a closed section of hose filled with water and put your bin on top of that, you can double your heat retention.  Keeping your bin near to a heat source can be a bit tricky so be careful, you don’t want uneven warmth.  One hot area of the bin is not as effective as keeping the whole area at a steady temperature.  Worms will flee a hostile environment so if one little spot is too hot they won’t hang around it anyway.  An example of this would be a heat lamp, if placed to close it will only work on certain areas, this is why we vote for the radiant heat method.  As always, vermicomposting can be as complex or simple as you chose to make it, we know of amazing systems that run off hot water tanks and little ones that work just fine with the heat vent.  The most important part is that you are a worm farmer, saving the world one kitchen scrap at a time.
