Jack Herer
A foundational Dutch hybrid named for the renowned cannabis activist, Jack Herer is celebrated for its complex, classic terpene profile and a balanced, uplifting effect that has maintained its popularity for decades.
About Jack Herer
Sensi Seeds named this strain after cannabis activist and author Jack Herer, whose 1985 book, The Emperor Wears No Clothes, became a cornerstone of cannabis advocacy. While Sensi Seeds has not publicly disclosed the exact genetic recipe, the strain is widely traced to a combination of Northern Lights #5, Shiva Skunk, and Haze. This lineage produces a classic aroma profile characterized by pine and earthy herbs, followed by notes of citrus, wood, and a peppery streak of spice.
Jack Herer is a fixture of Dutch breeding culture and has served as breeding stock for a sprawling family of hybrids. Its reputation is supported by numerous competition wins, including the 1994 High Times Cannabis Cup and a first-place finish in the sativa category at the 1999 Cannabis Cup. Users frequently report an experience defined by a bright, clear-headed lift with an energetic and creative streak, followed by enough relaxation to maintain a balanced effect.
Plant characteristics
Jack Herer typically grows tall, with Sensi Seeds recognizing several distinct phenotypes within the line. Flowering generally runs 50–70 days, depending on the selection. Most plants produce dense, resin-heavy flowers and substantial yields, though growers should expect variation in structure, flowering time, and the balance between Haze-like and heavier indica traits.
