More out of interest than anything else, but perhaps it might come in genuinely useful over the course of this year. I chose a model with a 50cm probe which means it should be able to reach well into the middle of my heaps.
My compost heaps are completely exposed to the elements with no kind of covering to keep the rain off, and my new toy arrived at the tail end of January after five weeks of temperatures continuously below 5C. In the greenhouse that day temperatures did scrape up to a whole 7C.
Despite the rain and cold however, the middle of one of my compost heaps was a balmy 13C.
I can’t deny that I was more than a little surprised to find it so warm at this time of year. Once the current pile achieves a reasonable size I shall make an effort to keep track of the temperatures.
