I did notice something today though. I think my greenhouse thermometer is broken (yes I am writing a post about a thermometer, how exciting!). Obviously as a carnivorous plant collector and enthusiast, it helps to know the temperature and environment in which I am raising my plants. Its about 3 degrees celcius outside, and according to the thermometer in the greenhouse, its 16'c in there. Last time I checked, you aren't visibly able to see your breathe when you exhale in 16'c temperatures. Still, the thermometer itself is about 7 years old. So I ordered a new one which as digital and displays the humidity as well as the temperature; which should help for as and when I decide to get tropical carnivorous plants.
