Jamaican Blue MountainJamaican Lambsbread F4
F4 hybrid strain of two Jamaican varieties, Blue Mountain and Lambsbread.
Jamaican Blue Mountain x Jamaican Lambsbread Regular is an F4 version of a cross between two of Jamaica's most treasured weed varieties.
The scents of this strain are heavenly, being two smell profiles, sandalwood and spices, with the latter pheno. having variations of expression. The effect, from trial reports, is incredible. You feel it in your head burning and strapping your head. Also sensations of heat, very cerebral, and as it wears off evolving into a meditative high. The earlier the harvest gives plants that are less meditative and more of a racy sativa effect.
