Another incredible hybrid with roots in the Jack Herer breeding program, this next-generation Sativa is one of Sensi’s more recent creations. Upon release, Mother’s Finest was an instant hit, winning first place for Sativa at the 2002 Cannabis Cup just a few months later. Mother’s Finest is more a Hazey offshoot of the Herer line than a direct Jack-descendant. However, just like Jack Flash, Mother’s Finest is best understood as a purposeful fine-tuning of Jack Herer’s multi-faceted gene pool.

Jack Herer sits right on the cusp of the Sativa-Indica divide, Jack Flash is a Skunk-heavy variant and our gorgeous Mother’s Finest – with her sweet-sour flavour rush and ecstatic cerebral high – represents the Haze-dominant side of the family Naturally, the most Sativa-leaning examples of Mother’s Finest will require the full flowering time, though this is still a considerably shorter period than comparable Haze hybrids. Less frequent phenotypes with a stronger Indica influence can mature in eight weeks. Mother’s Finest gains height quickly when blooming, even in her more Indica form, so growers with limited upward space should flower early. Like other mostly-Sativa hybrids, this strain can be put into 12/12 as rooted clones or small seedlings.

The divine sight and smell of Mother’s Finest in full flower will delight any lover of cannabis, right up to the most dedicated Sativa worshiper. Her conical bud formation takes shape early in flowering as profuse sprays of long-haired calyxes sprint along the stem and branches to join up the clusters at each internode. In later weeks, the spear-shaped colas expand into impressive lime green stalactites of crystal-smothered bud. As her pistils darken, the calyxes of Mother’s Finest swell and harden, maximising the surface area available for resin glands to multiply. Some phenotypes display extra-vigorous production, forcing calyxes into miniature peaks at the top and sides of large buds, giving the main colas a wickedly horned look. Elements of musky, fruity skunk and earthy Afghanica are clearly detectable beneath the sharp pine-Haze aroma of Mother’s Finest buds.

Jack Herer’s sublime gene-pool has been refined, with desired traits reinforced largely through back-crossing. Over multiple generations, our favourite Herer mother was infused with a precise blend of Super Skunk and Haze, undergoing rigorous selection and testing at every stage.

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.

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.

Sensi’s champagne of strains is named in honour of Jack Herer, author of The Emperor Wears No Clothes. Through tireless activism and his landmark book, Jack Herer can take most of the credit for reminding the world that cannabis in all its forms has always been one of humankind’s most valuable resources, and that we can literally save the planet with hemp!

The sublime blend of tropical Sativa high and monstrous Indica resin production captured in Jack Herer must be seen and sampled to be believed. At their peak, buds are so thickly smothered with clear trichomes that they appear sugar-frosted or sparkling with dew-drops. This crystal-coating extends to spear-leaves, fan leaves and even to Jack’s stems and stalks.

Plants from seed show favourable variation, due to Jack Herer’s complex background and delicate balance right at the cusp of Sativa and Indica. Enhanced features from both sides of the family are strongly evident and are expressed in different combinations, allowing growers to select mother plants tailored to their circumstances and tastes.

Three of Jack’s four main phenotypes are heavily Sativa-influenced while the fourth has a growth pattern leaning towards Indica – fast-flowering and relatively compact with a dense, expansive, rounded bud structure that’s suited to cash-cropping. Jack’s Sativa phenotypes can also produce a good per-metre or per-plant yield when cultivated skilfully, though it is rare for these crops to be sold commercially. Most growers who have watched their succulent, super-sized calyxes swell and mature will be hesitant to sell such buds, and the best Jack Herer is often passed around a select circle of friends – an example of one of those things that money just can’t buy.

The trait common to all Jack Herer phenotypes is a dazzling double-edged potency – a stratospheric cerebral high underpinned by a breathtaking body-buzz with seismic power. Smokers should be prepared to feel the earth shake beneath their feet – which can be a very pleasant feeling when your head is firmly in the clouds.
