Who Was Jack Herer?
With a name like Emperor of Hemp, you can imagine just how crucial Jack Herer was to the legalization of cannabis in the US. This legendary cannabis activist tirelessly pushed cannabis to be recognized for its medicinal and therapeutic benefits.
He was born on June 18, 1939, in New York City and lived a relatively ordinary American life until his first experience with cannabis in 1969, which he described as a “lightbulb moment” that sparked his lifelong mission to challenge its ban and grow the cannabis community.
This led him to co-found Help End Marijuana Prohibition (HEMP), an organization dedicated to advocacy and education, and he thoroughly studied every aspect of marijuana, from its industrial benefits to its medicinal and recreational uses.
His 1985 publication, The Emperor Wears No Clothes, often referred to as simply “The Emperor Wears,” made a lasting impact on society.
It provided an in-depth history of cannabis and exposed how political and corporate interests, such as the promotion of synthetic materials like nylon by DuPont, contributed to its prohibition.
One unexpected way Herer’s influence expanded was through the cannabis strain named in his honor. The Jack Herer strain was developed in his Sensi Seeds. It is a sativa-dominant hybrid believed to include genetics from Northern Lights, Haze, and Shiva Skunk.
This strain, celebrated for its uplifting clarity, and mental focus, as well the significant stamina it provides is a great reflection of Herer’s own endurance. It is a recognized medical grade strain that is distributed in Dutch pharmacies for therapeutic use.

How to Grow Jack Herer Seeds?
The next aspect of Jack Herer that we consider is just how easy it is to grow. Whether you are an indoor grower or an outdoor one, there are loads of useful tips in the sections that follow.
Indoor Growing

Indoor growers should also keep the humidity levels higher than with most cannabis plants at 60-70% during the vegetative phase and 40-50% during the flowering stage to reduce the risk of mold and mildew.

Harvest the plant when the trichomes are cloudy white, and pistils turn amber. After harvesting, the buds were dried in a dark, cool space, and cured in airtight containers.
Outdoor Growing
Jack Herer thrives outdoors in warm, sunny weather with daytime temperatures that range between 70-80°F (21-27°C). For the best results, these plants should be grown in well-draining soil with a pH of 6.0-7.0, and sunny spots that receive at least 8 hours of direct sunlight daily.
