Jack flash seeds
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.

Basic / Breeders Info

Jack Flash is an indica/sativa variety from Sensi Seeds and can be cultivated indoors (where the plants will need a flowering time of ±65 days ) . Sensi Seeds’ Jack Flash is/was never available as feminized seeds.

Sensi Seeds’ Jack Flash Description

Jack Flash is an easy to grow Jack Herer hybrid made by crossing our Award Winning Jack Herer with our best Super Skunk and the original Haze father.

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.

Average flowering period (60 – 70 days)
45% Sativa / 55% Indica
