“Jack Herer” Feminized Cannabis Seeds – Sensi Seeds

Jack Herer Feminized by Sensi Seeds: this legendary hybrid pays homage to his name. But be warned – try Jack once and you will probably never want to smoke anything else. Its effect is long lasting and perfectly balanced.

Officially recognized as one of the few medical cannabis strains in the Netherlands, Jack Herer Feminized is the prime example of an ultra potent strain with enormous levels of resin and THC.

Sensi Seeds’ Jack Herer Feminized is a THC-rich (50% sativa, 50% indica) hybrid strain for indoor growing. There are several phenotypes with different growth characteristics. The lasting effect is felt both in the mind and in the body.

Cultivation of Jack Herer Feminized

Most phenotypes exhibit distinct sativa growth behavior, along with resin production and the lush flowering of an indica. Growers should be aware that these plants grow vigorously during the flowering phase.

However, there is a rarer indica-dominant phenotype that doesn’t spread as much and is more compact overall.

You must see the buds of this variety – they are among the largest in existence. With sativa phenotypes, resin-coated calyxes form in several places, giving the plants a wild look.

Speaking of resin: carefully grown buds shine with a thick layer of THC-rich trichomes. As this diamond dusted look is retained in the dried buds, they are hugely popular with vendors and smokers.

If you examine a gem under a microscope, you will see that it is composed more of resin glands than of plant tissue.

Harvest and advice

Depending on the phenotype, Jack Herer Feminized is ready to harvest in around 10-12 weeks. Plants with a strong indica dominance can be harvested after as little as 8 weeks. Remember that this cannabis strain was developed for indoor cultivation.

Outdoor growing will only be successful in a warm climate with lots of sun.

In the right hands, Jack Herer Feminized cannabis seeds produce a lush yield that can be further increased with specific techniques such as Sea of ​​Green (SOG), Screen of Green (SCROG), Supercropping and Lollipopping.

Effect, flavor and scent of Jack Herer Feminized by Sensi Seeds

As varied as the growth behavior may be, in terms of effect, Jack Herer® is incredibly consistent. The high-energy cerebral high is accompanied by a breathtaking body buzz. So don’t be surprised to feel the earth shake beneath your feet as your mind hovers in the stratosphere.

If you like weed with a high CBD content and low psychoactive effects, you should look for a different variety.

When grown indoors, plants of this strain produce only a subtle scent, making them a great choice for discreet stealth growers. Only when they are dried do they develop their wonderful aromatic bouquet.

Most buds have a complex, sharp and savory hash tone that, depending on the phenotype, blends with Afghan tones and fruity skunk flavors.

Did you know?

Jack Herer Feminized by Sensi Seeds has won almost all of the current awards.

The original variety has dominated harvest festivals around the world for years. But Jack wouldn’t be Jack without taking it one step further. Jack Herer Regular was included in the official cannabis program of the Netherlands as a great example of a strain with a high THC content.
