compost thermometer is worth having
Since I got my compost thermometer I have been checking the big bin. I got it up to 140 yesterday afternoon after we had some sun. This morning it was back down to 120. I think the black plastic and sun created a differences of a full 120 degrees. I have to check again this afternoon and see if I got 140 again. It has only been in the high 60's to low 70's, but it we had a hot day of 90 which we not have very much, maybe I could get 150? I added Starbucks coffee and kellogs amend. I was lucky and got ground three times this week. The key thing is going to Starbucks in the morning. People drink more coffee in the morning and they have more grounds. The grounds were making the pile too wet, so I put the UCG on the ground to let them drain out before I put them in the bin. But, you can't let them sit out there very long or they will attract flies. The pile is still too wet and I should turn it, but there are no bugs in the pile. I may have time to turn it on Sunday, but I hate to lose all of this heat.
If I did not have the compost thermometer I would have missed this information. I can tell if it is hot or not, but not by how much by checking without a compost thermometer. There is a good deal on amazon, the one I bought and reviewed is doing great and not falling apart. But, you should read the reviews before buying some people claim they falling apart or the dial breaks.
