What the sources say it wants
Each line shows the band, then the kind of source and the citation. "Published" means the number is printed on the cited page; "derived" means it was computed from published numbers with the formula recorded on the row; "external API" rows are refreshed nightly from a live source; "curated" rows are OAT's own working values from June 2026.

Keystone status
Partial. The KEEP rule asks for a growth stage and a band in each of light, air and root zone before a crop counts as complete; this plant is in the keystone with what its sources give so far.
Generated 2026-09-15 from the OAT plant keystone. Source types and citations are carried on every row; the keystone snapshot that the Library instruments read is plant-targets.json and its quality sheet is plant-targets.quality.json.
