Jack Herer Autoflower Origins

The marijuana strain known as Jack Herer earned its name as an homage to the best-selling, world-famous author of The Emperor Wears No Clothes. Mr. Herer was also a legendary cannabis activist of his time.

Jack Herer was originally bred and cultivated by Sensi Seeds as a medical cannabis strain. It features superior genetics designed to trigger soothing feelings and happy thoughts after consuming it. Created in the mid-1990s in Holland, it’s gained a lot of fan fair throughout the years, much like its namesake.

Jack Herer hybrid is a combination of the following other strains of cannabis:

  • Haze Sativa
  • Shiva Indica
  • Skunk Indica
  • Northern Lights #5 Indica

Its rich genetic background led to multiple variations of the strain. Today, it’s now widely recognized as a medical-grade of marijuana by Dutch Pharmacies. The strain has won multiple awards for its quality and potency.

What are Jack Herer Autoflowers

Once upon a time we only knew cannabis indica and cannabis sativa plants. These are seasonal plants that start growing in Spring and are ready to be harvested when days turn shorter – so towards Fall.

Indoor growers learned to imitate nature by manipulating this light cycle.

In the early ’80s a third species, Ruderalis, was brought to Amsterdam. This plant is a cannabis relative that was discovered in Siberia. Breeders found that this Ruderalis plant would flower after just a few weeks, regardless of light differences. These ruderalis genes were combined with existing indica and sativa strains and the autoflower type was born.

Nowadays you can find autoflowering variants of all sorts of popular strains. They grow smaller plants but they’re easier to grow and you can harvest much sooner than with photosensitive plants. Great for new growers, growing in a small space or if you want multiple harvests per season!

We advise also reading our germination instructions for guaranteed results.
