Jack Flash (Regular Seeds)

How do you improve the best cannabis in the world? When working on a new strain from the illustrious Jack Herer line, that was the big question since we’ve always had a particular love for Sativas, one thing Sensi breeders wanted to change. The myth that delicious, cerebral, tropical strains were too difficult or low-yielding for the average indoor grower. 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 favorite we infused a  Herer mother with a precise blend of Super Skunk and Haze.

Jack Flash (Regular Seeds) is the triumphant outcome of that program. Inbred with the bulk and vigor of her Afghani-Skunk ancestors without sacrificing any of Herer’s sumptuous Haze high. 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 (Regular Seeds) is astounding in every way. Because her flavor, yield, and mind-body potency are virtually unparalleled. Growers with space for medium-to-large plants should select this phenotype as a mother.

While most members of the Sensi family rate Northern Lights#5 x Haze or Jack Herer as their all-time favorite ganja, Jack Flash is another serious contender for the title and is steadily gaining ground on the two world champions Sativas.
