If you’re looking for a sensual, cerebral, and sublime cannabis hybrid, Sensi Seeds’ Jack Flash is a perfect choice. Sensi started with Jack Herer’s gene pool to create Jack Flash and then crossed it with two more of their top strains: Super Skunk and Haze. It originated in the Netherlands as an Indica-dominant hybrid, but its ability to produce a high that lasts longer than most sedatives may prove useful to patients needing immediate symptom relief.

Many medical marijuana patients report that it relaxes the body, but some also find that the energetic effects help them focus on work tasks or even long-term projects. In addition, it can help patients cope with stress and anxiety, so many medical patients have found it a great choice for those dealing with depression and fatigue.

The adverse effects are few and include dry mouth or eyes, fatigue, and minor paranoia. The THC levels average between 14 and 17 percent, yet Jack Flash’s potency varies considerably according to the strain used to produce it. It offers an earthy citrus aroma perfect for its Jack Herer parent.

Jack Flash is a perfect choice for those looking to grow it indoors. It can produce a high in as little as 8 to 10 weeks but can be grown outdoors if you live in climates with cold winters and can cope with the fact that Jack Flash may not flower until late fall, although it will then develop quickly. It produces generous yields, has a fast flowering time, and has a strong cerebral effect reminiscent of her Haze father.
