- Rootless internal grow logsRootless Farm workshop
EC/pH/yield logs from in-house grows. Raw CSV is linked from each individual experiment post; posts that lack raw data are not published (see /legal/editorial-standards).
Editorial standard
We prefer university extension publications and peer-reviewed studies over secondary aggregators. When a numerical range is contested across sources, we publish the conservative envelope and note the disagreement on the relevant page. Internal grow logs are clearly marked and dated; raw data is published alongside any claim we derive from them.
