Introduction

Genetics and Lineage

Jack Herer is a hybrid strain, typically characterized as a 50% Sativa and 50% Indica, although some cultivators may list it as a Sativa-dominant hybrid. The strain was developed in the 1990s by Sensi Seeds in the Netherlands and is a cross between three key genetic strains:

  • Haze: A classic Sativa known for its uplifting effects.
  • Northern Lights #5: An Indica known for its relaxing properties and resinous buds.

This carefully curated lineage contributes to Jack Herer’s striking characteristics, making it versatile in both adult-use contexts.
