Even though the greenhouse is not as lush with green things as it is during the summertime, January has not been bad.  With the new thermal mass, inside temperatures have been twenty degrees higher than outside at night.

So much to the plants’ delight, with nighttime lows in the thirties, the interior temperature has stayed in the fifties.  The plants that survived the freeze in the greenhouse last month (before the thermal mass) and in fact are now thriving.  All the new plants are doing great.
