Growing Jack Herer Autoflower (indoors and outdoors)

Regardless if you already have any experience under your belt, anyone can grow an exceptionally high-quality weed with the Jack Herer auto seeds. One of the main reasons for this is that the plants are highly resistant to mold, fungal diseases, and pests.

Therefore, growers describe her as a 'dream to grow' and guarantee she will not disappoint, especially when you provide your plant with the right amount of care and attention.

Jack Herer auto seeds are suitable for indoor and outdoor and greenhouse growing. Jack Herer Auto prefers a temperate, Mediterranean, and dry climate when grown outdoors. Are you not blessed with such a climate? Then grow indoors or in a greenhouse.

Her Sativa traits cause the plant to grow slightly taller than average. However, as a grower, you can only be pleased about that—the bigger the plant, the more yield.

Plant height

Thanks to her height of 80 cm to 100 cm, the auto Jack Herer feminized plant is very suitable for growing indoors. Grown outdoors, however, the Jack Herer Auto can reach a height of up to 120 cm.

Flowering time

Jack Herer autoflowering plants grow very fast and have a flowering time of only 8 to 9 weeks! This means that you can expect to be able to harvest surprisingly quickly. Often the plants are ready for harvest within 12 weeks!

Jack Herer autoflower yield

Indoors, you can harvest up to 400 grams per m². Outdoors, you can harvest up to 100 grams per plant.

You can maximize your harvest by applying SOG or SCROG.


Due to its Sativa dominant properties (50%) and a THC content that can reach up to 19%, this weed offers a robust, vivid, and euphoric high. Although the buzz is powerful, it is not too overpowering. Above all, prepare yourself for feelings of happiness with a relaxed body and soul.

Because of these effects, this weed is often used medicinally by people who suffer from nervous tension or want to relieve pain.

Side effects

There are a few non-serious side effects associated with Jack Herer Autoflower. Dry mouth, sometimes called "cottonmouth," is perhaps the most common side effect. Sufficient fluid intake will quickly remedy this. You may also experience dry eyes.

Smell and taste

The aroma of Jack Herer Auto is quite typical of Sativa strains. Sweet undertones are reminiscent of forest fruits with a slight hint of green citrus—a sublime taste with nuances of pine.

The smoke of Jack Herer Auto is thick and suppresses any urge to smoke anything else. You will most likely experience an urge to snack after consuming, though.


Jack Herer Autoflower is named after the internationally known author of a book entitled 'The Emperor Wears No Clothes,' which discusses the many uses of cannabis and hemp. Hemp is an industrial fiber and essential medicine. Jack Herer was also a leading cannabis activist in the fight for the legalization of marijuana.

The Jack Herer strain was first cultivated as a medical cannabis strain. It exhibits superior genetics specifically designed to induce calming feelings and euphoria. She was first developed in Holland in the mid-1990s and has attracted much attention, just like her namesake.

Its rich genetic heritage has also resulted in numerous crosses, with Jack Herer being the base. Meanwhile, the weed is also officially recognized as medicinal cannabis by Dutch pharmacies.

So far so good, she's growing beautifully. I haven't harvested yet but I'm at day 70 with what looks like another 2,3-4 weeks left didn't start flowering until about day 50 or so.
