Grow facts

  1. AllBud (strain database) CBD and THC

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.

Source: CTU strain dataset (public strain listings and breeder info, checked by CTU), verified Oct 2026. Potency, flavor and effects vary by grower, batch and plant. Facts no source lists are left out.

About Jamaican

Jamaican is a sativa cannabis strain. Lineage on record: Jamaican Landrace.

How strong is Jamaican?

Reported THC for Jamaican is 10%. That puts it below most strains we track: its midpoint is higher than about 3% of all strains in our research dataset with a strain-specific THC figure. Potency varies by grower, batch and lab, so read these numbers as typical values, not guarantees.

Jamaican aroma, flavor and terpenes

Flavor notes reported for Jamaican: earthy, coffee and woody. The terpenes listed most often are pinene (pine), myrcene (earthy, musky) and terpinolene (fresh, herbal). Pinene is the lead terpene for about 4% of the high-confidence strains in our dataset, so it is a less common lead. Terpenes shape smell and taste; their levels change from batch to batch.
