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 18.76% THC, 0.10% CBD, and 0.28% CBN. 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.

According to Green House, White Widow grows short with light green leaves and white, crystal resin-covered buds in a 56-63 day flowering period. The seed bank also recommends letting the plant flower for the full 63 days to get its full spectrum of cannabinoids and terpenes. Green House also reports that White Widow grows well indoors — especially under the Screen of Green (SCROG) method — and outdoors in mild, temperate climates.
