Description

Pay homage to one of the most foundational and influential strains ever created. Jack Herer by Sensi Seeds is a world-renowned, multi-award-winning masterpiece developed to honor the memory of the legendary cannabis activist and author of The Emperor Wears No Clothes. Officially recognized as a medical-grade staple in Dutch pharmacies, this elite hybrid represents the absolute pinnacle of classic Amsterdam breeding.

By masterfully crossing a towering, pristine Haze with the robust, heavy-hitting forces of Northern Lights #5 and Shiva Skunk, Sensi Seeds locked in a spectacular genetic treasure trove. In the grow room, Jack Herer exhibits incredible vigor and structural variation depending on the phenotype selected. Sativa-leaning variations will stretch significantly during their flowering cycle, producing elongated, running colas that are completely smothered in a dense, shimmering glaze of high-quality resin glands. Because of its massive trichome production, it remains an absolute holy grail for old-school hash makers and concentrate connoisseurs alike.

What to expect? The aromatic bouquet of Jack Herer is complex, sophisticated, and instantly recognizable. It treats your senses to a dominant wave of crisp forest pine, earthy haze, and warm, spicy wood, beautifully cut by sharp tropical citrus and a hint of black pepper on the exhale. Boasting a high THC content, its effects offer a flawless duality of mind and body. It launches a soaring, energetic, and deeply euphoric cerebral high that sharpens focus and ignites creativity, which is perfectly balanced by a soothing, long-lasting physical body buzz that keeps you relaxed but fully functional.

Frequently Asked Questions

What are feminized cannabis seeds?
Feminized cannabis seeds are bred to produce almost exclusively female plants, typically around 99% of the time. Since only female plants produce the resin-rich buds growers want, feminized seeds remove the guesswork of sexing plants and growing out unwanted males.
How are feminized seeds made?
Breeders trigger a female plant to produce male pollen sacs, usually by spraying it with colloidal silver during early flowering, which disrupts the plant's hormone signaling. That pollen carries only female genetics, so pollinating another female with it produces seeds that grow into female plants.
What are the main advantages of growing feminized seeds?
Every seed has a strong chance of becoming a bud-producing female, so you don't waste time, space, lights, or nutrients raising males you'll have to discard. This makes planning your grow simpler and more space- and cost-efficient.
What's the difference between feminized and autoflower seeds?
Feminized (photoperiod) seeds need a light-cycle change to flower and generally take longer to mature (roughly 12-20 weeks), but tend to grow larger and yield more. Autoflowering seeds flower automatically based on age, finishing faster (about 7-12 weeks). Most modern autoflower seeds are also feminized.
What germination and success rates can I expect from feminized seeds?
Fresh, properly stored feminized seeds from a reputable seed bank typically germinate at a 90%+ rate and produce female plants around 99% of the time. Seeds usually sprout within 24-72 hours under warm, moist conditions.
Are feminized seeds good for beginners?
Yes, feminized seeds are one of the most beginner-friendly options because they remove the need to identify and cull male plants, leading to more predictable growth and fewer surprises.
Do feminized plants produce their own seeds?
Not usually, since there's no male plant present to pollinate them. However, significant stress (temperature swings, light leaks, physical damage, or nutrient problems) can trigger a female plant to develop hermaphroditic traits and self-pollinate.
How should feminized seeds be stored, and how long do they stay viable?
Store feminized seeds in a cool, dark, dry place, ideally in an airtight container in a refrigerator. Properly stored seeds commonly remain viable for 2-5 years, though germination rates gradually decline the longer they're kept.

Schnell und zuverlässig. Jederzeit eine Überraschung mehr in der Packung. Jetzt bin ich auf die Ergebnisse gespannt. Die ersten waren schon mal super! Im vergleich zu anderen Anbietern keimt jeder Samen. Die Automatics sowie die Feminisierten haben sehr super Ergebnisse gebracht. Jetzt bin ich auch auf die Hybriden gespannt.

Hi! I recently purchased 3 seeds from you. 1 green gelato, 1 wedding gelato and 1 super kush. I have done many purchases from you in the past with no problem at all and I'm very satisfied with your products. Unfortunately, 1 seed, wedding gelato, didn't sprout at all, so I left with only two seeds to work with. There is no way I have done anything wrong since I every time have 100% success in the past with your seeds. If you have any ideas I would be really happy to hear that. As far it concerns the shipping I am very satisfied with it. Thank you very much.
