Introducing Jack Flash #5 Feminised Cannabis Seeds by Sensi Seeds

Get ready to experience the best of Jack Herer's direct descendant with Sensi Seeds' latest creation - Jack Flash #5 Feminised. This all-female version of Jack Herer has been refined through back-crossing and infused with a precise blend of Super Skunk and Haze to create a reliable, consistent, and feminised variation of the spectacular Jack Herer.


  • Flowering: 55 - 75 days
  • Yield: 125 g
  • Height: 140 - 160 cm
  • Type: Sativa / Indica

By isolating the perfect balance of traits, Jack Flash has reduced the four common phenotypes of Jack Herer to two recurring forms, representing the contrasting sides of her heritage. The Indica form is compact enough for SOG, with rapid and highly distinctive bud development. The Sativa-dominant Jack Flash is a truly world-class example of cannabis, with a flavour, yield, and mind-body potency that 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.
