Grow facts
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.

In public strain data, Black Lime is classed as an indica credited to Aficionado Seeds. The parent strains on record are Northern Lights and Purple Kush.
Public listings give Black Lime a THC level of 16%, which is on the milder end. Compared with all strains in our research dataset that have their own THC figure, it is higher than roughly 12% of them. Potency varies by grower, batch and lab, so read these numbers as typical values, not guarantees.
People most often describe the flavor of Black Lime as pepper, citrus and earthy. Its top listed terpenes are myrcene (earthy, musky), caryophyllene (peppery, spicy) and pinene (pine). Myrcene is the lead terpene for about 44% of the high-confidence strains in our dataset, so it is a common profile. Terpenes shape smell and taste; their levels change from batch to batch.
People who have tried Black Lime most often report feeling relaxed, euphoric, sleepy, tingly and uplifted. These are user reports, not promises. Effects differ from person to person and depend on dose, setting and tolerance.
