Jack Flash 5: Potent Modern Version Of Jack Herer


Sensi Seeds didn't rest on the success of their famous Jack Herer and further fused it with Super Skunk and Haze. This resulted in a remarkable strain that produces two phenotypes and is a great plant for indoor growers who want that special sativa effect with indica growth characteristics. Jack Flash 5 is an award-winnig cultivar with sativa-dominant genetics (65% sativa, 35% indica). She combines great aroma and effect with an ease of growing that is usually associated with the Skunk family.


Jack Flash 5 can develop two phenotypes - one is more sativa-leaning, the other shows more indica traits. The sativa phenotype grows tall with slender lateral branches that become covered in dense buds. The indica phenotype is more compact, stocky and well-suited for SOG. The calyxes on this one are super fat, almost abnormal. Depending on the phenotype, flowering will finish between 55-75 days. Jack Flash 5 is a heavy yielder that will satisfy every grower. Experienced gardeners can push her to the limit but the strain can also be grown by amateurs. Outdoors, she likes a sunny and Mediterranean climate and can be harvested around the mid/end of October.


Flavourwise, Jack Flash 5 has all the classic earthy, skunky and spicy notes of Jack Herer, with the addition of fruity apricot and orange. The well-cured buds also have a lemony fragrance and when they are smoked, fresh hints of mint and pine are noticeable. Some even compare the aroma to Earl Grey tea because of its pleasant mandarin orange and bergamot tones. When it comes to the effect, you can expect happy relaxation combined with an energetic buzz, really good for creativity and inspiration. But beware, the uplifting and rushing high is not for the inexperienced tokers! It is not so much psychedelic, more buoyant, cerebral, bouncy, social and talkative. Patients use it for tension relief and to treat anxiety, depression and stress.
