Key Lime Jack is a sativa bred by Happy Dreams Genetics in Humboldt County, California, from a cross of Bling Cheesecake and Jack Herer. Maven Genetics grows it indoors as part of a partnership with Happy Dreams and files it among the sativas in its strain library.
The cultivar pairs a modern Happy Dreams cheesecake line with Jack Herer, the award-winning Dutch sativa from Sensi Seeds. Leafly lists Maven's flower at 30% THC.
Happy Dreams bred it in Humboldt
Happy Dreams Genetics is a Humboldt County breeder that calls itself a sustainable, award-winning legacy grower. Its catalog runs past 50 cultivars, from Glazed Lemon Thai and Miracle Grapefruit to Ajo Blanco, Blueberry MAC and cheesecake cultivars such as Lime Cheesecake and Vanilla Cheesecake.
The breeder lists Key Lime Jack as a sativa that flowers in 63–70 days. Outdoors, Happy Dreams puts harvest between October 15 and October 25. Its top terpenes are terpinolene, limonene and caryophyllene.
Bling Cheesecake meets Jack Herer
Bling Cheesecake comes from The Bling crossed with Mac and Cheese, and The Bling itself sits in the Happy Dreams catalog. Leafly lists Bling Cheesecake as a 50/50 hybrid at 23% THC with limonene as its dominant terpene, and reviewers describe the effect as mostly energizing.
Jack Herer is the older half. Sensi Seeds created it in the Netherlands in the mid-1990s from a Haze hybrid, Northern Lights #5 and Shiva Skunk, and named it after the cannabis activist and author. Leafly lists it as 55% sativa at 18% THC, with a 4.4 rating across 5,159 reviews.
Jack Herer also brings terpinolene as its dominant terpene, the same compound that leads Key Lime Jack. Leafly records four Jack Herer phenotypes, three sativa-dominant and one with more indica-like traits.
Maven's indoor sativa lineup
Maven is a California brand focused on premium indoor flower, rare genetics and concentrates, built on what it calls meticulous phenotyping and precision cultivation. The company runs a Connoisseur Club membership, a Feed The Muse program and its own retail location.
Maven's strain library places Key Lime Jack among its sativas, next to Orange Bellini, Chrome Dome, Zuzu Berry, Sour Sangria, Orange Sapphire, Lemon Cherry Tropicana and Pineapple Biscotti.
Weedmaps lists the Maven flower as a sativa-leaning hybrid developed with Happy Dreams, high in limonene and terpinolene. Listed prices at Columbus-area dispensaries run $24.49–$34.99.
Sungrown in Humboldt, washed for hash
Key Lime Jack also grows outside Maven's rooms. Full Moon Farms, an original Humboldt County family operation, grows it outdoors under organic, sungrown methods. Nasha Hash carries that Full Moon Farms harvest in its hash library, credited to Happy Dreams as breeder.
Nasha lists the Full Moon Farms expression as an evenly balanced hybrid with terpinolene, limonene and beta-caryophyllene on top. Its hash shows up as unpressed material with a light caramel color.
Leafly gives Key Lime Jack a 4.3 rating across 13 reviews. Reviewers most often report feeling energetic, creative and euphoric, uplifted without much sedation. On flavor, they point to lime and citrus over an earthy base.
