Jack Flash®
How do you improve the best cannabis in the world? That was the big question when working on a new strain from the illustrious Jack Herer line. Since we’ve always had a particular love for Sativas, one thing Sensi breeders really wanted to change was the myth that delicious, cerebral, tropical strains were too difficult or low-yielding for the average indoor grower. Actions speak louder than words, so creating a Jack hybrid with all the growing advantages of a Skunk seemed the best way to prove our point.
Jack Herer’s sublime gene-pool has been refined, with desired traits reinforced largely through back-crossing. Over multiple generations, our favourite Herer mother was infused with a precise blend of Super Skunk and Haze, undergoing rigorous selection and testing at every stage.
Jack Flash is the triumphant outcome of that program — inbred with the bulk and vigour of her Afghani-Skunk ancestors without sacrificing any of Herer’s sumptuous Haze high. In isolating this particular balance of traits, the four common phenotypes of Jack Herer are reduced to two recurring forms in Jack Flash, representing the contrasting sides of her heritage. The Indica form is compact enough for SOG, with rapid and highly distinctive bud development. Calyxes swell to outrageous sizes, piling atop each other to form resin-saturated ropes which build into multi-point crowns on terminal buds.
The Sativa-dominant Jack Flash is astounding in every way. Growers with space for medium-to-large plants should select this phenotype as a mother,- her flavour, yield and mind-body potency are virtually unparalleled. Significant height gain in flowering, paired with the ability to completely fill out with solid, running, Skunk-Haze bud means that best results are seen when Jack Flash’s Sativa form is allowed to finish at 1m or taller.
While most members of the Sensi family rate Northern Lights#5 x Haze or Jack Herer as their all-time favourite ganja, Jack Flash is another serious contender for the title and is steadily gaining ground on the two world champion Sativas.

SENSI SEEDS PIONEERED THE CANNABIS INDUSTRY TO BECOME THE WORLD’S LARGEST SEED BANK PIONEERS OF THE CANNABIS SEED INDUSTRY
Sensi Seeds pioneered the cannabis seed industry in 1985. Today, the company is the world’s largest cannabis seedbank with over 500 varieties. These genetics and the brand name have become true classics in the cannabis community. The Dutch government chose Sensi Seeds genetics to develop the medicinal cannabis supplied by pharmacies.
Sensi Seeds aims for the normalization of cannabis use and recognition of the plant’s therapeutic and industrial benefits. This led the company to open the world’s first cannabis museum in 1985. The Hash Marihuana & Hemp Museum is now present in both Amsterdam and Barcelona and has welcomed over two million visitors.
Together with the museum, Sensi Seeds regularly hosts the Cannabis Culture Awards. This award celebrates those who have taken a stand for the acceptance of cannabis. Winners include Sir Richard Branson, and former Prime Minister of the Netherlands Dries van Agt.
Sensi Seeds opened its sister-company, HempFlax in 1993. The company developed new processing methods and purpose-built equipment for hemp cultivation. These innovations have since become the industry standard. They are now used by leading agricultural and construction equipment manufacturers, including John Deere.
HempFlax products are widely used in the textile, food, construction and body-care industries. The automotive industry has also adopted hemp, including brands like BMW, Mercedes and Bentley. Hemp is making a successful come-back and HempFlax is leading the way.
The world’s attitude towards cannabis is changing. Countries are now legalising cannabis for medicinal and recreational use. The possibilities for industrial, nutritional and pharmaceutical applications of hemp continue to surprise us. Sensi Seeds will play its part and remain at the forefront of these developments.
Sensi seeds strives for the acceptance of cannabis worldwide and believes that responsible consumption of cannabis can enrich one’s life.
With more than 30 years’ worth of experience in the field of cannabis, Sensi Seeds is fully aware of the crucial role that cannabis can play for humankind. The company is pleased to see the current increase in attention and recognition for the plant worldwide, not only as a medicine but also as a raw material.
Sensi Seeds is committed to preserving the genetic diversity and accessibility of the cannabis plant for future generations, and disseminating information and knowledge about the beneficial effects the plant can have when used appropriately.
Jack Flash was created by the cannabis breeder Sensi Seeds, which set out to improve on the legendary Jack Herer by creating a hybrid that combined these powerful genes with the highly sought-after growing attributes of a Skunk. In this case, the breeder mixed Jack Herer female with Sensi’s Super Skunk and Haze to produce trichome-rich buds, high THC, and low CBD, according to Amsterdam Seed Center.
The strain won third place for Best Cannabis in the 2004 High Times’ Cannabis Cup in Amsterdam.
