Today is graph day!
This week I have been thinking about temperatures. If you remember back to when I set up the temperature probes there would be thousands of temperature readings. All that data in a giant, overwhelming spreadsheet taunting me because I am not so sure how to use it all. While figuring that out I've been looking at just a few days at a time. Kind of like snapshots.
The greenhouse temperature itself is a good place to start.

I realized after I made the above chart that I had used soil temperature data instead of air temperature. See what having oodles of numbers in a huge spreadsheet does to me?
Below I graphed soil and air temperatures together. You can see the treads I highlighted in the soil temperature graph can also be seen in the air. The major difference is air temperatures are much more volatile. They seem to jump up or down a few degrees each hour. This could be due to cloud cover, or air movement from the fans.

* This data represents five days in the greenhouse I am working in.
Other greenhouses or high tunnels may have similar temperature trends but they will not be identical. *
