The Silver Pearl marijuana strain parent comes from the U.S. where it was developed in the 1970s and added to Sensi's stable in the early days of the breeding program. A fast-finishing outdoor variety, Early Pearl was a sweet, mostly sativa strain with excellent mold resistance. Crossed with Northern Lights #5, one of the super Afghanis, has become a building block due to it's great uniformity and compact buds. Skunk 28.5 is a Skunk #1 backcross that is consistent and has a high calyx-to-leaf ratio.
