Jack Herer auto seeds are suitable for indoor as well as outdoor and greenhouse growing. When grown outdoors, Jack Herer Auto prefers a temperate, Mediterranean and dry climate. 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.

Thanks to her height of 80 cm to 100 cm, the auto Jack Herer feminised 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 5 to 7 weeks! This means that you can expect to be able to harvest surprisingly quickly. Often the plants are ready for harvest within 10 weeks!

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

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

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 as an industrial fiber and as a crucial 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 a lot of attention over the years, just like her namesake.
