I have a large, south facing windowsill in my apartment that seems like a good location to grow a fairly wide variety of carnivorous plants. The apartment is heated to 68f , but I can achieve true "highland" conditions (ideal for the Nepenthes and rosetted sundews I want to grow) if I leave my window partially open overnight. While this will achieve an ideal ambient nighttime temp in the apartment (mid 50s-60f), I am concerned about drafts of very cold air damaging my plants in the winter. I live in a very cold climate and nighttime lows in the winter regularly drop below 0f. To get the desired amount of nighttime temp drop in winter, the window will only be left opened a crack overnight.
I am concerned that even if my "ambient" temps are ideal, sporadic blasts of (very)cold air could injure my plants. Any Nepenthes growing on the windowsill setup will be in a terrarium, which will provide an extra layer of insulation.
