Jack Herer Seeds Information

Bred in the Netherlands in the mid-1990s, Jack Herer seeds originate from a potent blend of Sativa Haze, Northern Lights #5, and Shiva Skunk. This combination has made a perfect Sativa-dominant strain that provides a creative, energizing, and uplifting high. Jack Herer is one of the most decorated cannabis strains out there, boasting numerous High Times Cannabis Cup wins since the '90s. With its robust yield of 400-500gr/m² and its low maintenance needs, it really is a cultivator's dream.

How to Grow Jack Herer Feminized Seeds

Jack Herer is a tall strain, reaching heights of over 220, and offering generous yields of 400-500gr/m². With a flowering time of 10-12 weeks, you will need to be patient, but you can be assured the wait will be more than worth it. Jack Herer thrives in warm, tropical, and sub-tropical climates and has a built-in mold-resistant nature. The plant structure is sprawling, with lush foliage that requires proper maintenance and defoliation to really thrive.

During the Vegetative Stage

In the vegetative phase, Jack Herer grows big fast, largely thanks to its Sativa-dominant genetics. Its structure is tall and lanky, with lots of stretching in the first half of the veg period. Training techniques such as low stress training, screen of green and topping can all be used to manage the plant's height and encourage more lateral growth. You should ideally start using these techniques at the start in the third week and continue to manipulate the structure of the plant as it grows, stopping before the flowering stage begins. During the veg stage give your plant a nutrient solution with plenty of nitrogen, building up slowly from the start and gradually tapering off before the flowering stage begins.

During the Flowering Stage

During the early flowering stage you will begin to see the preflowers form around the nodes. It will be a few more weeks until these develop into fully formed flowers. The buds will eventually develop a rich green hue, and become increasingly solid and dense as you come into weeks 6-10. You will start to notice the trichomes appearing around the third week, indicating the plant's readiness for nutrient transition. You can then switch to a more phosphorus and potassium-rich nutrient and taper this off in the final 1-2 weeks before flushing and harvest. Keep a close eye on the the trichome color from the 8th week onwards as this can help you gauge harvest time—amber for a more body-relaxing effect, milky for a cerebral high.
