How warm is it?
The only way to find out is to measure it, the human body is useless for monitoring temperature.
During cold weather, have you every come into the house and thought it was lovely and warm. Then only a few hours later you start fiddling with the thermostat, as you start to feel cold. But its still the same temperature you have just got used to it.
Much better is a wireless option, you check on your plants from your house, it is worth paying a bit more for one that stores the history.
