Continuing the tradition of Sensi Seeds improving on their best work, Sensi Seeds is delighted to present Jack Flash – an all-female version of Jack Herer´s direct descendant!

To create Jack Flash, Herer´s sublime gene-pool was refined, reinforcing desired traits 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. By altering this program only slightly and adding a unique ‘father´ plant to the mix in the final stage, we have been able to produce Jack Flash #5 – a reliable, consistent, feminised variation on Sensi Seeds spectacular Jack Flash. Jack Flash has 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 a truly world-class example of cannabis. 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 in 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.

There is no other seed bank in the world that has been coveted with more awards than Sensi Seeds. From the Highlife Cup to the Cannabis Cup, Sensi have achieved unrivalled legendary status in the seed bank world.

At the end of the seventies, Ben found out that cannabis seeds did not fall under the cannabis prohibition; it was only the plant that was prohibited and not the seeds. As it was not illegal to sell seeds, Ben reasoned that the production process should not be illegal either. He started his seed company after a lawyer confirmed this insight and in 1985 the Sensi Seed Club, also known as the Sensi Connoisseurs’ Club, came into being. Ben took over a company called the Seed Bank in 1991 and the gene libraries were merged to create the Sensi Seed Bank as we know it today.

Sensi Seeds search for cannabis genetics has never ceased in the last 30 years. Their dedication towards genetic preservation has also never diminished. To this day, Sensi are true to their roots and are now, more than ever, aware that the future of cannabis genetic research lies in its past, in the genetics that started it all.

Sensi genetics offer not only the high yield and range of effects people search for, they actually represent a part of Cannabis’ history.
