Ah..., so that's why it's been such a mild winter! ;-)

Can someone recommend a good min/max thermometer for my greenhouse please?
I purchased one with 2 indicators that looked like pencil lead and a
button to press to "zero" them. It was hopeless, the indicators did not
always zero and on doing so tended to bounce back up. The only way to get
it to work was subjecting to centrifugal force by wind milling it with my
arm.
