Jack Flash grows into quite a tall plant unless vegged. for an extremely short time indoors before being put into flowering. There are two pheno-types; one is shorter and expresses more indica in its structure – this is a great choice for SoG. The other is more sativa in expression and grows taller with more stretch during flowering. Indoor-grown plants will finish in 60 – 70 days depending on the pheno-type with outdoor plants in warm climates being finished either towards the end of October or in early November. Such late finishing times mean that regions with the likelihood of an early frost or two should be avoided.
Jack Flash is a three-way marijuana hybrid created by crossing Sensi’s award-winning Jack Herer strain with Super Skunk and an Original Haze male. It is a versatile indica-dominant plant that is very easy-to-grow producing high yields.
Dried buds are quite big with medium density and have an aroma that mixes, lemon, pepper, Skunk and Haze. Its flavour is sweet/acrid with some spicy fruit along with Haze notes. The effect produced by Jack Flash is very typically sativa with an uplifting, cerebral high coupled with nice, cosy bodily feelings.
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.
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.
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.
Flowering: 60-70 days Height: 140-160 cm Yield: up to 125 gr
