Grow facts come from the breeder first, then seed banks and strain databases. With 2 sources we show the range and the middle; with 3 or more, the range and the median, after leaving out values far from the rest. The breeder's own value is the anchor, unless it is far from every other source (outside their range and more than 20% from their median); then we show the full range and the median of all of them. A fact from a single source is marked "1 source", and a fact no source lists is left out. Yields are converted to one unit: indoor per square meter, outdoor per plant.

CTU writes every profile from these facts; we do not copy other sites' descriptions. Values that are a generic default in the source data are left out. Last checked Oct 21, 2026.
