Jamaican sativa lines have a character of their own that gets lumped in with generic Caribbean genetics too often. Lambs Bread and related cuts tend toward a peppery, woody profile with a moderate stretch and a flowering time around eleven to thirteen weeks, which makes them more manageable than the Thai types. The regional page on https://hazesativaseeds.com separates the Jamaican lines from the Colombian and Mexican ones and notes which seed sources are actually working with island stock. A lot of what is sold under those names is a Skunk cross with a nice label.
