Jack Flash Regular Cannabis Seeds by Sensi Seeds

Are you ready to experience the best cannabis in the world? Sensi Seeds has taken the illustrious Jack Herer line to new heights with their latest creation, Jack Flash Regular. With a particular love for Sativas, Sensi breeders wanted to dispel the myth that cerebral, tropical strains were too difficult or low-yielding for indoor growers.

Through rigorous selection and testing, Jack Herer's sublime gene-pool has been refined and infused with a precise blend of Super Skunk and Haze, resulting in the triumphant outcome of Jack Flash Regular. This strain combines the bulk and vigour of her Afghani-Skunk ancestors with the sumptuous Haze high of Jack Herer.


Jack Flash Regular represents the contrasting sides of her heritage with two recurring forms. 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 phenotype is astounding in every way, with significant height gain in flowering and the ability to completely fill out with solid, running, Skunk-Haze bud. Growers with space for medium-to-large plants should select this phenotype as a mother for its flavour, yield, and mind-body potency.


  • Flowering: 60-70 days
  • Height: 140-160 cm
  • Yield: up to 125 gr
  • Awards: 3rd Place 2004 - 17th High Times Cannabis Cup - Overall Winner

While Northern Lights#5 x Haze and Jack Herer are Sensi Seeds' all-time favourite ganja, Jack Flash Regular is quickly becoming a serious contender for the title. Try it for yourself and experience the burst of flavour, cerebral high, and impressive yield that this strain has to offer.
