We use liquid tests and sometime test strips to measure pH, NO2, NO3, NH3, KH and GH, and Johan gave us a tester to measure EC. We have been scribbling it on notes, filling it in at google docs and emailing about it, but there is not much structure. So now we set up some feeds at Cosm and are finding ways to manually update them.

We really need to get our data collection structured. The data from our sensors is sent to Cosm, so we are trying to find a way to manually fill in the data we collect ourselves at that service too.
