Preparing a glasshouse climate log so a drawing does not fight the book
Glasshouse files are some of the cleanest we see and some of the most confusing. Clean, because a logger often sits still for months. Confusing, because irrigation is written in a paper book, vents are moved by hand, and the logger clock was last set in October.
Before you send a series, put three things in the same envelope or the same message:
- The channels as named on the logger (ridge, tray, soil, whatever you actually call them), with units.
- Irrigation and vent hours from the book, even if they are messy. We would rather hatch a Friday afternoon than invent one.
- Whether the logger follows winter time, and the date of the last clock set.
Missing Sundays are common when someone pulls the file and the logger pauses. Leave them missing. A drawn line that sails through a day nobody recorded will be quoted later as if the house had been watched.
If two houses share one export, split them. A paired figure of ridge against soil is useful. A paired figure of east house against west house, without a note that they do not share a vent gear, is a quarrel waiting for the owner.
