How to Grow Jack Herer Regular
Jack Herer Regular is the regular-seed version of one of the most celebrated sativa-leaning strains ever bred. It pairs a potent 20–22% THC with a citrus, fruity, orange flavour and a focused, happy, relaxed effect, on a vigorous, productive plant that breeders and purists reach for when they want to work with the genetics.
Built from Shiva Skunk crossed with Haze and Northern Lights, this is a 60% sativa, 40% indica strain that blends clear, cerebral haze energy with the resin and structure of its skunk and Northern Lights parents. The result is a flavourful, high-quality classic with a bright citrus-orange nose.

Climate and Where to Grow It
Jack Herer Regular does well in a temperate climate with mild, steady conditions and good light. Its hardy skunk and Northern Lights heritage makes it adaptable, so it performs both outdoors and in a controlled indoor tent, reaching a manageable 1.5 m.
Outdoors it finishes around October, and a single well-grown plant can bring in a generous 500–600 g in a good spot, with indoor plants producing a similar 550–600 g/m². Keep humidity in check as the resinous buds fill in to protect the bright citrus aroma.
Indoors, aim for daytime temperatures around 68–80°F (20–27°C) and keep steady airflow through the canopy. A tidy, well-lit space gets the most out of this productive classic.
Working with Regular Seeds
Because these are regular seeds, roughly half your plants will be male and half female. For a bud harvest you need the females, which show thin white pistils (hairs) at the nodes a couple of weeks into flowering. Males instead form small round pollen sacs, and you remove them before they open so they cannot pollinate the females.
If you want to breed or make your own seeds, this is exactly where regular genetics shine: keep a healthy male and let it pollinate a chosen female to preserve and work this legendary Jack Herer line. For most growers the plan is simple: identify the sexes early, cull the males, and let the females finish into resinous, seedless flowers.
Feeding Schedule (EC Guide)
This is a vigorous, productive plant with skunk heritage, so you can feed it steadily through bloom to support the heavy buds. Start low, build up as the plant asks for more, and taper off for the final flush so the citrus-orange flavour stays clean.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Build the frame, raise nitrogen gradually |
| Early flower | 1.2–1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4–1.6 | Peak bloom feed while the heavy buds swell |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Flowering and Harvest
Once you flip to 12/12, bloom runs about 8–10 weeks. The sativa lean shows in the structure: some flowering stretch early on, then long, resinous colas rather than squat indica nuggets, so a little early training keeps the canopy even.
Jack Herer Regular stacks frosty, citrus-scented flowers through the back half of bloom. Harvest when most trichomes have turned cloudy with a few amber for the fullest, most balanced expression, and run a short plain-water flush in the last week or two before you cut.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15–18°C) and 55–60% humidity for 7–14 days, until the thin stems snap rather than bend. A slow, even dry preserves the bright citrus-orange aroma and stops the resinous buds drying unevenly.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure brings the zesty orange and fruity character forward and smooths the smoke, which is exactly what this legendary strain deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Jack Herer Regular is a frosty, resinous plant, so the trim is excellent for dry sift, bubble hash or rosin, giving you a bonus run of citrusy concentrate from material most growers throw away.
Flavor and Terpenes
Jack Herer Regular leads with bright citrus and orange over a fruity base, the fresh, zesty profile that helped make the original such a classic. It is lively and uplifting rather than heavy or earthy, with just a hint of its skunk heritage underneath.
It carries a deep terpene stack. Six stand out: limonene drives the zesty citrus and orange note; terpinolene adds a fresh, lifted top note; myrcene anchors a soft, fruity base; pinene brings a clean, fresh edge; caryophyllene adds a peppery, lightly skunky warmth; and farnesene rounds in a soft, fruity note. A supporting cast of terpineol, carene, humulene and more fills in the herbal corners.
Effects and Best Use
With its 60% sativa base, Jack Herer Regular is reported as focused, happy and relaxed. It is a bright, clear-headed profile that leans toward daytime and creative or social use, with just enough body ease to keep it balanced rather than racy.
With a potent 20–22% THC it is strong but approachable, so it is easy to enjoy without being overwhelming. That focused, uplifting high, the zesty citrus-orange flavour and the legendary genetics are exactly why growers keep coming back to Jack Herer, especially in regular form for breeding.
Common Problems and Pro Tips
Jack Herer Regular is a rewarding but demanding grow listed for experienced growers, so plan for its regular genetics and haze stretch.
- Sort the males early: as a regular strain it produces both sexes, so check pre-flowers and pull the males early unless you are keeping one for breeding.
- Manage the haze stretch: its Haze side reaches up hard after the flip, so flip a little earlier, use a SCROG net or top the plant, and give it headroom.
- Feed and support through bloom: it is a high yielder with a longer, hungrier bloom, so feed it steadily and stake the colas before they lean under the weight.
Expert tip: this is a legendary line that rewards experience rather than shortcuts. The bright citrus-orange flavour holds up best with a slow dry and a patient cure in jars.
Frequently Asked Questions
Is Jack Herer Regular indica or sativa?
It is sativa-dominant, at 60% sativa and 40% indica, which gives it a focused, uplifting, clear-headed effect with a light body side. That sativa lean also means a real haze stretch after the flip, so train the tops and give it headroom to keep the canopy even and well lit.
How long does it take to flower?
About 8 to 10 weeks once you switch to a 12/12 light cycle, with outdoor plants finishing around October. As a haze-influenced sativa it uses the full window, so keep air moving through the canopy and start checking trichomes toward the end to catch it at your preferred ripeness.
Are these feminized seeds?
No. Jack Herer Regular are regular seeds, so they produce both male and female plants. Remove the males early if you only want buds, or keep one for breeding. Check the pre-flowers in early bloom so you catch the males before they open and pollinate the females you want to keep.
What does Jack Herer Regular taste like?
Expect a bright citrus and orange flavour over a fruity base, driven by its limonene, terpinolene, myrcene and pinene terpenes. Those citrus notes fade with heat, so dry slowly in a cool, dark space and cure in jars to keep that fresh, zesty character in the finished flower.
How much does it yield?
It is a strong producer: 1.8 to 1.97 oz/ft² (550 to 600 g/m²) indoors, and 17.64 to 21.16 oz (500 to 600 g) per plant outdoors in a good season. Training the haze stretch into an even canopy and supporting the colas helps the plant reach the top of that range.
Is it a good strain for breeding?
Yes. As regular seeds it produces males and females, so you can keep a male to pollinate a female and preserve or work this legendary Jack Herer line. That is exactly why breeders and purists seek out the regular format rather than a feminized version of a strain this iconic.
