Jamaica is a family of Jamaican varieties of cannabis and derived hybrids derived from them. Jamaican varieties are, as a rule, genetics with the prevailing Sativa . They grow quite fast, unlike the classic Sativa and are famous for their "high" effect, which acts more on the mind, rather than on the body. There is a theory that Jamaican varieties are obtained by crossing local Sativa with pure Indica, which was brought by Indian immigrants. Varieties have a high yield, for example Jamaica Sativa gives graver 500-700 gr per m2! A fairly resin-covered cones of this grade with a THC level of 24% give an unforgettable experience. The smell of Jamaican varieties is sweet and sour, floral.
