Jack Flash Regular cannabis seeds
Jack Flash® Regular Seeds by Sensi Seeds. One of the best Jack Herer strains was crossed with just the right amount of Skunk and Haze, shortening the flowering time, and the plants' height is noticeably reduced, making them easier to grow. Its flavor and effects make it unique and it competes directly with Sensi Seeds' other two champion Sativas, Jack Herer and NL#5 x Haze.
Perfect seeds for indoor growing
Indoors, with good space, we can easily get 500 g per m² in about 70 days of flowering. If we grow our plants directly at 12/12, we will have a natural SOG, full of buds from this fantastic plant. Its production and quality are offered in specimens over 1 m tall. We emphasize its good adaptation indoors, taking into account providing it with good space for its proper development.
How to grow Jack Flash Regular outdoors
Outdoors, it grows very healthy and well-structured; good sunny weather will help generate large flowers that quickly turn into light, whitish buds. Our plants will be ready for harvest at the end of October, with an approximate yield of 600 g per plant under optimal growing conditions. The structure is stable and well-branched, giving us specimens with explosive flowering and a notable improvement in resistance to fungi and mold, as well as in the quality and final weight of the harvest.
Earthy and incense flavors
Jack Flash® is the best definition of potency, a cerebral and euphoric effect, with that earthy, incense-like flavor that strongly resembles the typical and legendary Haze flavor. It culminates in the formation of tight, stacked buds, very resinous and crown-shaped at each of its tips, covered in an extremely sticky resin.

I got several phenotypes, some extremely productive. The peppery and spicy aroma is its most notable feature. Did anyone get a phenotype with purple tones?

Good strain! It is vigorous and adapts well to the SOG method. Has anyone tried it in SCROG? I'm considering it for the next run.
