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."
– tlover tonet

"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

    Brian Mills –

    I was impressed by this plant, in just a few hits I can find myself absolute relaxation, ending with a cool and refreshed mind and I have a bright disposition. Thanks to this wonderful and amazing Jack Herrer Autoflower. Crop King you’re such an amazing seed banks! Great Job! Looking forward to your new strain to come out.

  2. Avatar for Keegs

    Keegs –

    The estimated time of growth and size are way off. My plant took 18 weeks and was over 5 feet tall.

  3. Avatar for Australopithecus

    Australopithecus –

    I have a JH auto in week four of bud. Smells real sweet and spicy. Can’t wait to try it.

  4. Avatar for Jeffrey

    Jeffrey –

    Oh boy! Life is great with Crop King seeds. Started 3 Jacks June 12th and now Aug 10 counting the days to harvest. There in my tent with 3 White Widow Autos which will be ready for Chop in a week or so. The Jacks have a slightly longer flowering time. Great for me time between to dry and start a cure. All 6 plants have responded to all my newby grow solutions. Looking forwarded to a huge yield. Thx Crop King

  5. Avatar for RJ

    RJ –

    The biggest yielding auto I’ve grown so far. One plant under LEC 315 3100k 18/6 from pop to chop. Grown in 4 gal fabric pot HP Promix with AN Sensi line. No stress of any kind – just tucking and limited late defoliation if it was blocking light to a budsite. Plant vegged like a photo for almost 30 days always showing good preflower but not flowering like your typical auto. I almost decided to shift it into a photo tent but it finally kicked in solid and when it went to full bloom – it went wild. Beautiful internode spacing – 85cm tall – and huge colas on every tip and hard as rocks. Chopped at day 85 and after drying down to 58%RH this one plant yielded 240 grams with over 80g in LEGIT colas. I’ve grown just about every CK auto (and other autos) for the last two years and this baby was the PERFECT plant! All the stars aligned on this one. ALL HAIL THE KING!
