Also known as Sour D and East Coast Sour Diesel (or ECSD,) Sour Diesel is a prolific strain with somewhat tumultuous origins. According to online sources, Sour Diesel gained prominence in New York in the mid-90s when breeder AJ (short for A**hole Joe,) accidentally pollinated a Chemdog 91 female with pollen from a Super Skunk he acquired during a trip to Amsterdam. The end result, Sour Diesel, was reportedly named for the way it soured business relationships as it spread through New York’s underground cannabis market, causing rifts as it changed hands among growers.

White Widow is a cross of two landrace strains, Brazilian and south Indian, from Green House Seed Company in Amsterdam. Green House breeder Arjan Roskam reports having developed White Widow in the early ’90s with fellow Netherlands breeder Ingemar. According to Arjan, the strain’s original name was Arnhem’s Wonder before he and Ingemar commercialized it in seed form and changed the name to White Widow. The winner of first place Bio at High Times Cannabis Cup in 1995, White Widow delivers a strong peppery cedar flavor and a complex, long-lasting high that starts with a relaxing haze and gives way to an explosive buzz, as reported by Green House. Green House has tested White Widow at 90.4% THC. The seed bank has also developed autoflowering and high-CBD autoflowering versions of the strain by hybridizing White Widow with Ruderalis and high-CBD strains, respectively. Green House Seed Co. carries all three versions of White Widow in feminized seed form.
