Hi All, My name is Daniel, I have a small farm in NW Washington. I was at a conference with Elaine Ingham yesterday.
She said you can get an oxygen sensor from Grainger for $400. I think her E-zine also lists a source for a less expensive one. Elaine also indicated that if the oxygen levels in tea are kept above 6 parts per million and you are using good compost and a good brewer that you should always have good tea and no pathogen problems. They are going to be doing more testing with the oxygen levels but it looks promising that people will be able to test their tea by monitoring oxygen levels. Does anyone have expierence cleaning bio-film from a flow form after making compost tea or preps?
