The taste is a complex mix of earthy floral notes accented by lemon, pine, spice, and woody undertones, making for a flavorful smoke that’s both bright and rich in aroma.

Growing Information

This strain is notably easy to grow and perfect for novices. It finishes in around 9–10 weeks without requiring light schedule changes, thanks to its autoflower genetics.

Indoor yields of 300–400 g/m² and outdoor yields of around 150 g/plant are typical under reasonable conditions. It can be harvested multiple times throughout the year given its autoflower nature.

Quick Grow Tips

  • Lighting: Provide 18–24 hours of light daily, no dark‑period triggering required.
  • Nutrients: Use light feeding; avoid overfeeding, particularly early in flower.
  • Watering: Maintain consistent moisture; avoid overwatering to prevent root stress.
  • Environment: Keep stable temperatures and moderate humidity; indoor height remains small for discreet setups.

"I am glad to be one of many visitors on this great site (:, thanks for putting up."

"Had several Jack seeds from an order a few years ago, but all germinated, and all grew to completion. Plants were about 2 ft tall, and each one yielded a couple of ounces. So - not the highest yield I've had, but pretty good. Almost all of the regular leaves yellowed and fell off by the end, but the buds just kept on growing, and everything turned out great. It has a really nice high - strong, but not so much that you can't do whatever you need to. Very energizing and clear. Highly recommended."
– Ombudman
⭐️⭐️⭐️⭐️⭐️
"Due of its odd earthy taste, I don't think I could ever grow to like Jack Herer. Although it seems to be present in all marijuana, this particular strain is too potent for my taste. I enjoyed the results but disliked the flavor. Would advise you to give it a shot and judge for yourself because, on the whole, the strain is good."
– Yohan A.
⭐️⭐️⭐️⭐️⭐️
"Still my favorite strain. I took the head bud, ground it let it dry over night and smoked it the next day. No curing. When I smoked the first joint of this beautiful 6' tall and 6' round plant in my basement. I got so high I used the tv remote like an imaginary seat belt before changing the radio channel. I'll be taken better care of this years and following the steps to see if I can grow it even bigger then the last Jack Herer auto crop king seeds I grew. Pictures and videos to come. I'll have it involved with my cannabis art website. Also a help from crop king seeds, massive crop = massive joint art. www.tharonscannabisart.com"

"Has a significant impact on concentration skills and appears to keep the same zen-focused energy for about two hours. While smoking other potent sativas, a buzz can be felt as a warm sensation in the stomach as opposed to a full-body buzz."
– Ali Pablo

    Just got my “present” in the mail, ordered 5, got 7!!!!!!!!!! so far 6/7 have popped after 1 day in a moistened papertowel. (funny, 30 years ago when I was kid I heard this was the best way to germinate). About to start in soil……Foxfire Farms Ocean Blend, I use Their Liquid Organic fertilizers, with great success on seeds I get here and there, I run 2 MARS 900 LEDs and 2x 315W CHL. So far so good, they have exceeeded my expectations so far……..Stay Tuned!

    Entering my 9th week from sprouting in an outdoor grow. Growing a little shorter (33 inches) but bushy. So many leaves when compared to the heavy Sativa Lambs Breath it grows next to but great density. I don’t weigh things but should get 2 qt jars of dried/cured bud per plant. More than happy with 2 jars after 10 weeks. Bio buzz soil with lots of perlite and 20% Cocoa. Big fan of AN for nutes.

    BudzzT1 –

    Great grow, very rugged to the elements. Slow start, but they grew about two feet tall and busy AF. Took about 13 weeks Got 78g if dense nugs off one, and 130g off the other. Very happy with the genetics. Would definitely grow again!
