Jack Herer

Description

Characteristics at a glance

Yield and difficulty figures are growing references for this line, drawn from strain databases and growing guides; they are not a guarantee of results or an indication for use, but catalog data for comparing varieties.

Who is this strain for?

Jack Herer suits anyone looking for a classic, long-cycle sativa (77–85 days), with a distinctive incense and hashish aroma, who doesn’t mind a somewhat more demanding grow than an indica’s.

Parentage and genetic origin

Jack Herer takes its name from the American activist and writer Jack Herer, and is one of the most recognized sativas in the European catalog. It emerged on the scene in the nineties and quickly became a reference point for describing the Haze character: long flowering, a slender plant and an aroma unlike almost anything else around. As happens with widely spread genetics, there are now numerous versions under the same name, worked on by different seed banks.

The documented lineage in this listing combines Haze, Northern Lights #5 and Shiva Skunk. Each parent contributes something different: the Haze block explains the stature, the long leaf and the extended cycle; Northern Lights #5 and Shiva Skunk introduce the resinous load and the denser, more Afghan notes of the profile. The resulting split is 90% sativa and 10% indica, one of the most markedly sativa-dominant in the catalog.

That context belongs to the Jack Herer strain in general, not to this particular line. The Trikoma Seeds version comes from our own mother plants, selected and maintained at our bank in Barcelona, and every format in this listing comes from that same selection. We do not distribute third-party material or resell genetics from other seed banks.

THC and CBD profile

The stated range is 20–25% THC across the parent lines. This is catalog data, not a measurement of each individual seed. CBD is low and not quantified in this listing.

Effects

• Cerebral and euphoric, very characteristic of the Haze line
• Energetic and stimulating, favors activity
• Creative, clear-headed
• Elevated effect without sedation, consistent with its sativa load

These are effects commonly described for this strain; they vary by person and do not constitute an indication for use.

Aroma and flavor

Jack Herer’s aromatic profile is among the most distinctive found in a seed listing. The description starts from two notes that don’t usually coexist: incense and hashish. The incense brings a resinous, dry register, almost like burnt wood, while the hashish adds a dark, dense layer that recalls pressed resin more than fresh flower.

On top of that base come Afghan nuances, which reinforce the earthy, heavy side of the whole, and a fruity skunk that breaks the seriousness of the profile with something meatier and sweeter. The slight hint of lime that closes out the description works as a counterpoint: a minimal, citrusy, sharp note that sits at the edge of the aroma and keeps it alive.

The structure reflects the stated 90% sativa. These are tall, slender plants, with long, narrow leaves and elongated buds heavily loaded with resin, visibly set apart from the compact silhouette of indicas. The stated indoor flowering of 77 to 85 days is the longest in the feminized catalog, characteristic of Haze-leaning lines.

Dominant terpenes

Indoor growing

Flowering of 77–85 days, the longest in the feminized catalog. Yield between 750 and 900 g/m² with 600W LED, according to strain databases. Moderate difficulty: somewhat more demanding than the indicas in the catalog, but it rewards careful cultivation.

Outdoor growing

Harvest in late October in the northern hemisphere and late April in the southern hemisphere. Yield of 1–2 kg per plant, according to strain databases.

How it fits into the catalog

• Boca Negra is the other great sativa in the catalog, at 75% sativa and 25% indica. Against Jack Herer’s incense and hashish register, its stated profile is clearly citrusy, of orange blossom and ripe orange.
• 69.G incorporates Jack Herer directly into its cross, alongside Amnesia, and serves as a point of comparison within the same lineage.
• Malquerida sits at the opposite end: 70% indica and a stated indoor flowering of 45–50 days, versus Jack Herer’s 77–85 days.

Other versions of Jack Herer

Jack Herer is also available in an autoflowering version: Jack Herer Auto, starting from the same selection of mother plants.

About the large formats

The 100 and 1,000-seed packs are single-strain packs. They are not mixes or assorted batches: they contain only Jack Herer and come from exactly the same selection of mother plants as the small pack, with no batches separated by format.

What changes is the price per seed. In the small pack it comes to €3.33, in the 100-seed pack it drops to €2.40, and in the 1,000-seed pack it stays at €1.20. You can check the rest of the strains available in large format at bulk seeds.

Frequently asked questions about Jack Herer

Why is it called Jack Herer?

The name comes from the American activist and writer Jack Herer, a well-known figure in cannabis history. It’s a name inherited from the strain in general, not from this particular line.

What genotype and THC does the listing state?

The stated genotype is 90% sativa and 10% indica, and the stated THC range is 20–25%. Both are catalog figures referring to the parent lines, not a measurement of each individual seed.

How much does Jack Herer yield?

As a growing reference for this line: between 750 and 900 g/m² indoors with 600W LED, and 1–2 kg per plant outdoors. These are catalog figures, not a guarantee.

Why is its stated flowering time so long?

The 77–85 days of indoor flowering stated on the listing are consistent with its Haze load, the highest in the feminized catalog. It’s the figure that sets it furthest apart from the indica-dominant strains, which state notably shorter cycles.

What other strains share its lineage?

Within the catalog, 69.G includes Jack Herer in its documented cross alongside Amnesia. It’s the most direct point of comparison if this lineage interests you.
