Seedsman tribute to Jack Herer
Now almost as renowned as its namesake, Jack Herer is a classic strain that combines the cerebral euphoria of a Sativa while maintaining the heavy resin production of an Indica. Jack Herer was created in the Netherlands in the mid-1990s where it was later distributed by Dutch pharmacies as a recognized medical-grade strain. Since then, the strain has taken home numerous awards for its quality and potency. This strain can be grown anywhere but indoor growers should wait 50 to 70 days for Jack Herer to flower.

Frequently asked questions
Is this strain suitable for my growing environment?

In theory most strains can be grown outdoors, indoors or in a greenhouse but how well they perform depends on the more exact environmental conditions. This is most important outdoors where climatic conditions can vary widely, so please check the strain information carefully. If your climate is more extreme or growing season shorter you should choose strain that is specifically adapted. Indoor and greenhouse environments can be controlled and made suitable for most strains although space can be a factor for strain that grow very large.

How difficult is this strain to grow?

Growing difficulty varies depending on a strain's resilience, structure and environmental needs. Some strains are more forgiving and better suited to beginners and a range of environmental conditions, while others may require closer control of factors such as light, humidity, temperature and feeding.

What can I expect in terms of cannabinoid content and yield?

Our product information and that provided by suppliers can be an indication of potential levels under optimal conditions, and it should not be assumed that results can be replicated in all conditions.

Is this strain suitable for beginners?

Strains described as beginner-friendly, easy to grow or resilient, in particular Autoflowering Feminised strains, are generally more manageable for less experienced growers. These varieties are often a more reliable starting point than more specialised genetics.
