Jack Herer Strain Information

Jack Herer strain description

Jack Herer is a popular name amongst weed enthusiasts. Apart from writing the controversial “The Emperor wears no clothes,” he was also one of the most illustrious pro-cannabis activists in history.

Being a much-respected figure in the marijuana industry, it was only a matter of time before a strain got named after him.

In honor of its namesake, the weed strain Jack Herer is a sativa-dominant hybrid and one of the most highly-rewarded and popular ganja varieties in the world. Often referred to as the “perfect blend” by its multitude of fans, this ganja will provide you with an exceptionally appealing flavor that leads to a well-balanced kick.

Created by Sensi Seeds in the mid-’90s, the aim was for Jack Herer buds to capture both the sativa’s transcending elevation and the indica’s heavy resin production. 

Jack Herer strain effects

Jack Herer genetics gave rise to several different variations of the breed, each with its own unique effects and features. Overall, stoners typically describe this sativa-dominant hybrid as calming, euphoric, clear-headed, blissful, and creative. Besides its recreational properties, it’s also widely recognized as a medical-grade cannabis strain.

Jack Herer strain grow information

The Jack Herer weed strain is one of the most widely cultivated and beloved ganja variants globally. For growers, it’s a dream come true as it’s a no-fuss plant that will thrive with minimum TLC, even under less than perfect conditions.

The Jack Herer strain yields bulky, high-quality buds within an exceptionally reasonable flowering time. It’s also naturally resilient against disease, mildew, mold, and bugs. As a low maintenance breed, the plants can be grown either outdoors or inside, provided you give them enough space as they can reach over six feet tall.

Growing the Jack Herer marijuana strain indoors in a hydroponic setup works extraordinarily well. Especially in combination with the Screen of Green (SCROG) method. It’s crucial to keep your plants warm (68° to 80° Fahrenheit) and provide them with plenty of food. The crop will flower for eight to ten weeks, developing massive colas.

It may be necessary to install support to prevent the branches from breaking under excessive weight. When they’re ready to harvest, the Jack Herer will yield between 14 and 17 ounces of delectable, potent buds per square foot.

Cultivating the Jack Herer weed strain outdoors requires a sunny, dry, and balmy environment. Being allowed to grow freely, the plants will reach their full potential. In a Mediterranean climate, you should be able to harvest around mid-October, and you can expect a yield of roughly 17.6 ounces of divine ganja per shrub.

Strain reviews for Jack Herer

Seeds arrived quickly, and the first two I planted came right up. Currently, they are growing nicely. I cannot comment on quality until after harvest.



Popped 5, but only one made it past 4 days. I got replacements for next time. The one that made it is healthy and already in full flower by week 4 and pushing 2 plus feet from the soil. I need to do some more training, but it already has 12-14 tops reaching for the light! Keeping my ph at 6.4-6.7 close to 6.5. She has about 6 and a half weeks to go, and I’ll update on dry yield once I’m done. I’m really happy with the outcome so far.

I have not had some good Jack in a long time and took to ordering some as a first grow in a long time. It turned out superb. I personally loved it, and more so after my most veteran friends who grow gave it a grade “f*****g A+” I quote. After a few months curing, it is even more amazing.



I haven’t had one of these that hasn’t left a smile on my face. Full thick grow every time.



Would 10/10 recommend this strain to grow to anyone! This was my FIRST EVER photoperiod grow, and she was a seriously amazing plant to work with. She was quite the yielder too! Pulling 184.1 Grams dried / cured / trimmed in 105 days seed to harvest.
