Jack Herer is a sativa strain, named after the marijuana activist and author. Sensi Seeds developed this strain from hybrids of Haze, Nothern Lights, and Shiva Skunk. It smells like a spicy pine tree and tastes even earthier. With side effects like uplifted mood, increased energy, and improved focus, this strain has a reputation for being morning medicine. It has been used to crossbreed a variety of other Jacks. This medical strain is a popular wake and bake, but insomniacs should steer clear to avoid accidental all-nighters.
