Jack Herer Auto is for those who like their cannabis with a bit of pedigree and a lot of punch. Named after the legendary activist and author, this autoflowering version of the iconic Jack Herer lives up to its namesake with energy, clarity, and unmistakable character.
It’s the kind of strain that doesn’t just get the job done. It does it with style. Expect a creative, heady lift that slowly melts into a chilled, content body buzz. No heavy sedation. No racing heart. Just a smooth, balanced experience that’s a joy to grow and even better to smoke. And with that built-in Ruderalis kick, even beginners can pull off impressive results without micromanaging the light cycle.
If you enjoy dialing things in and maximizing every detail, the Jack Herer photoperiod version gives you more to work with.
Jack Herer Auto takes its lineage seriously. It blends three absolute classics: Haze, Northern Lights, and Skunk, and tops it off with Ruderalis to make it flower automatically. This mix didn’t happen by accident. It’s a deliberate blend of cerebral power, physical relaxation, and stability in the grow room. Originally bred in the Netherlands to capture Jack’s uplifting spirit in plant form, the strain became a worldwide hit for a reason. It works, and it works well.
Jack Herer Auto hits with a bright, euphoric uplift that clears mental fog like a breeze through an open window. It’s energizing, happy, and just creative enough to spark ideas without sending thoughts into overdrive. Great for daytime use or social settings where you want to stay sharp and relaxed at the same time.
The flavour? Classic Jack. That unmistakable spicy Haze sits up front, with sweet pine and a touch of citrus rounding things out. The smoke is smooth, and the aroma’s got that sharp, herbal zing that lets you know you’re dealing with a true sativa-forward hybrid.
With THC levels reaching 19%, Jack Herer Auto delivers a solid, satisfying potency that’ll please both casual and seasoned smokers. The 0.1% CBD content isn’t going to move the needle much medicinally, but the overall cannabinoid balance keeps things clear-headed and manageable.
This one’s got a diverse terpene spread. Nerolidol and its isomer Trans Nerolidol lend that fresh, floral twist, while Delta 3 Carene brings a mild citrusy tang. Terpinolene and Alpha Pinene give it that unmistakable Haze sharpness. Limonene adds a sweet, lemony lift, and Eugenol and Alpha Phellandrene round it off with warm spice and herbal depth. Throw in Cymene and Gamma Terpinene, and you’ve got a terp profile that’s as energetic as the high itself.
This is an easygoing strain with just enough personality to keep things interesting. Whether you're working with a tent in the corner of your flat or have a sunny greenhouse setup, Jack Herer Auto is forgiving, fast, and reliable. Perfect for beginners who want a bit more complexity without the drama.
Indoors, she stays neat and manageable, usually landing between 80 cm and 100 cm tall. Excellent for tight spaces or stealth setups. Outdoors, she stretches a bit more, typically growing between 100 cm and 120 cm, but still keeps a compact footprint. That Ruderalis heritage gives her solid resistance to pests and fungal issues, which means less stress for growers in variable climates.
She also doesn’t need a lot of babysitting when it comes to lighting. Just give her some decent soil, a stable environment, and let her run her course. No flipping schedules. No second-guessing.
Jack Herer Auto finishes flowering in about 56 to 63 days, making it one of the quicker sativas out there. Indoors, you’re looking at yields between 350 to 400 gram per m2, which is more than respectable for a compact auto. Outdoors, expect around 80 to 100 gram per plant if conditions are right.
Whether you're after a mental spark, an easygoing grow, or just want to try one of the most iconic names in cannabis history without the long wait or high maintenance, Jack Herer Auto ticks all the boxes. Fast, flavourful, and full of charm, it’s a modern take on a true classic in autoflowering form.
