Jack Herer is one of the best-known sativas in the European catalogue and the reference Haze in our collection. At Trikoma Seeds it comes in two versions, feminized and autoflowering, which start from the same selection of mother plants but behave very differently: one needs the change in photoperiod and a long cycle, the other flowers by age. In this guide we compare the two using the data on their product pages, so you can see what changes from one to the other and which one best fits your collection.

A long-cycle Haze and its automatic version

The reference is the feminized Jack Herer, whose documented lineage combines Haze, Northern Lights #5 and Shiva Skunk. The Haze block accounts for its stature, long leaves and extended cycle; Northern Lights #5 and Shiva Skunk contribute the resin load and the denser, Afghan notes. The result is a 90% sativa, 10% indica genotype, one of the most markedly sativa in our catalogue. Our line comes from our own mother plants, selected and maintained in our seed bank in Barcelona.

Jack Herer Auto declares a Ruderalis × Jack Herer cross and was obtained from the feminized phenotype of our own Jack Herer, with very few differences between the two. The ruderalis contribution is what makes it autoflowering: the switch from growth to flowering depends on the plant’s age rather than on a change in photoperiod.

These are catalogue figures declared for the parent lines, useful for comparing strains with each other; they are not a measurement of every seed or a guarantee of results.

Feminized Jack Herer: the reference Haze

This is the version that defines the line and the one with the higher declared THC of the two, 20–25%. Its declared indoor flowering, 77 to 85 days, is the longest in our feminized collection, something typical of lines with a strong Haze load; outdoors, the product page places the harvest at the end of October in the northern hemisphere and the end of April in the southern hemisphere, with 1–2 kg per plant as a reference. Its aroma is one of the most distinctive in the catalogue: incense and hashish as the base, Afghan nuances, a fruity skunk and a light touch of lime that keeps it lively. The product page rates it as moderately difficult, somewhat more demanding than the indicas. It is the natural choice for anyone who wants the original Jack Herer and does not mind waiting.

Jack Herer Auto: Haze character without depending on photoperiod

The automatic version keeps the family’s aromatic register, which its product page sums up as unmistakable Haze: spicy, with an incense background and very persistent. In structure it keeps the stature of its line, with elongated spears that are somewhat airier than the dense flowers of the indicas. Like every autoflowering strain, it does not need a change in photoperiod to flower. In return, its declared THC (14–19%) sits several points below that of the feminized version, and its reference yield, 675–810 g/m², is calculated with about 20 plants per 600W LED. We compare it with the rest of the autoflowering strains in autoflowering strains: size, THC and aroma of the 12 in the catalogue.

Which one best fits your collection?

  • If you want the original Jack Herer, with the highest declared THC and the incense and hashish aroma: the feminized one.
  • If you want the Haze character in a plant that flowers by age: the Auto.
  • If you want to compare how the family behaves: both together. Formats can be mixed, and each version is available in packs of 6, 100 and 1,000 seeds of a single strain.
  • If you are interested in Jack Herer as part of an assortment: Super Mix Sativa includes three Jack Herer seeds, and Super Mix Auto three Jack Herer Auto seeds.

Jack Herer in other crosses in the catalogue

Our Jack Herer is also a parent of another strain: 69.G crosses it with Amnesia Haze, with 60% sativa, about 70 days of flowering and an intense, citrusy aroma. And if you are interested in the Haze register in an automatic, Wendy Auto is the other Haze autoflowering strain in the catalogue, with 15–20% declared THC.

We compare the four Haze sativas in the catalogue in sativas and Haze: Jack Herer, Wendy, 69.G and Boca Negra, and the differences between the seed types in feminized, autoflowering and fast version: what’s the difference. We have the same comparison guide for White Widow, AK-74, Critical Plus, Patagonia, Gorilla, Blueberry, Total Cheese, Wendy, Sweet Madness and The Palmar.

Frequently asked questions

Do the two versions come from the same genetics?

Yes. Jack Herer Auto was obtained from the feminized phenotype of our own Jack Herer, with a Haze × Northern Lights #5 × Shiva Skunk lineage, and there are very few differences between the two. The ruderalis contribution is what makes it autoflowering.

Which one has the higher declared THC?

The feminized one, with a range of 20–25%. The Auto declares 14–19%. These are catalogue ranges for the parent lines, not measurements of every seed.

Why does the feminized version have such a long cycle?

Because of its sativa and Haze load: it declares 77–85 days of indoor flowering, the longest in our feminized collection. The Auto does not depend on photoperiod and flowers by age, with no declared number of days on its product page.

Is there a Jack Herer Fast?

No. Jack Herer is available in two versions in the catalogue, the feminized one and the Auto. There is no fast version of this line.
