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

    Doman Singh –

    I had ordered some seeds from the dispensarie in my hometown unfortunately, only one pack of the two strains I purchased only germinated. I was ready to go buy some new ones when a friend told me to contact you guys. I have to be honest I didnt expect any help or like most customer services lines they would have told me I was out of luck. The young woman i spoke to sad that I didnt get her name she was unbelievably helpful and want to say that the customer service was BEYOND helpful and I am very appreciative of the companys help. THANKS SO MUCH AGAIN

    I grew one of these Jack auto flower. It was 11 weeks from popping out of the soil until harvest. Awesome smoke. One of the best strains I have had. Crop King is the way to go.

    I germinated two Jack Herer’s and put them in DWC in my tent with LED mars hydro 700W . These things are launching out of the buckets and its only week three. Can’t wait to see the results, thanks CK.

  4. Avatar for Happy Jack

    Happy Jack –

    These Jack Herer auto fems are amazing! First, they STINK early on so be prepared. Ran 18 straight, 4 months. Took one of four and produced pollen colloidal silver. very pretty pink male flowers. Crossed back with sibling resulted in regular photo with a bit less reak and more sativa traits, longer finish time. Can’t say enough good about the strain, the energetic effect and CropKingSeeds. There’s a lot of options these days, I’d plan on running more of these sweet babies. Very compact yet massive too

    Jer –

    Just finishing growing 4 Jacks in DWC. The fastest one took 17weeks from pop. The biggest one of the four went 19 weeks and was 4.5′ tall. This plant overgrew the other 3 taking most of my small 3’x3′ tent. Yielded 6oz off that one plant and probably about the same off the other 3 combined. Two I still have yet to chop, 135 days and counting… Gotta take a point off for the way longer than advertised schedule, but the smoke is great, smell is excellent and high is focused and creative.
