This seems like a great forum for wormers. I'm just getting started on having my pound or so of spineless employees make castings for me in a 18 gallon bin in my basement.
Does anyone collect empirical data from their bins and product? I've read that you ideally want a temperature between 60-70 degrees F, neutral PH and about 70% humidity. So, if you're compulsive, you want a thermometer and some other measuring tools. Its been a long time since high school, so what do you use to test PH? I remember using litmus paper in school. Where does one buy lutmus paper, or is there another device that can test the PH of your bin?
As far as humidity, I suppose a cigar store might have a barometer or something to test with.
What other data points would one want to collect to ensure you are running a good bin? Is there a tool that can test for carbon or nitrogen content?
