Mango Jack is a feminized, mostly sativa strain from Dready Seeds. The breeder built it by crossing its own White Jack with Mango Kush. Dready describes a very tall, vigorous plant that yields well indoors and outdoors.
Its size is the headline. Seedfinder lists outdoor plants reaching up to 3.5 meters. Flowering runs 70–80 days, with an outdoor harvest at the end of October.
Dready Bob and a seed program running since 2008
Dready Seeds has bred cannabis seeds since 2008 and also extracts CBD products. Its breeder, Dready Bob, is the technical mind behind its strains. He has studied cannabis genetics for more than two decades.
Mango Jack sits in a catalog that GrowDiaries lists alongside Dready Berry, Blue Bubbleberry, Northern Cheese and Tangie Berry. Like those releases, it is sold as a feminized photoperiod seed. Growers trigger flowering with the light schedule.
White Jack brings two Dutch classics
White Jack is Dready's own cross of Jack Herer and White Widow. Seedfinder lists it as a sativa-dominant, feminized-only hybrid with a 60–70 day bloom, THC of 16–20% and good mold resistance. Outdoors it also reaches up to 3.5 meters and produces massive buds.
Jack Herer came from Sensi Seeds in the Netherlands in the mid-1990s. Leafly traces it to a Haze hybrid, Northern Lights #5 and Shiva Skunk. It is named after the activist who wrote The Emperor Wears No Clothes. Its line also runs through Sweet Seeds' Black Jack, a cross of Black Domina and Jack Herer.
White Widow is a 1990s release from Green House Seeds, also in the Netherlands. Leafly describes it as a Brazilian sativa landrace crossed with a resin-heavy South Indian indica, at roughly 60% sativa. The same breeder later made Super Lemon Haze, a two-time Cannabis Cup winner.
Mango Kush fills out the other side
Mango Kush supplies the indica weight. Leafly lists it as a Hindu Kush and Mango hybrid at about 21% THC. Its dense buds carry orange pistils and thick, shiny trichomes. Plants average 4–5 feet and flower in 9–11 weeks.
That parent has its own descendants, including Gorilla OG and Mango Sherbet. In Mango Jack, it pairs with White Jack's height and vigor to produce a plant that leans sativa in both structure and timing.
GrowDiaries traces the combined family back to sativa landraces from Thailand, Colombia, Mexico and India, plus indica lines from Afghanistan and the United States. That spread explains why the cross grows tall while still stacking good-sized buds.
Long bloom, big frame, late harvest
Seedfinder puts Mango Jack's flowering at 70–80 days, or roughly 10–11 weeks, with medium to high yields. Outdoor crops finish at the end of October, and plants prefer coco or organic soil with plenty of light.
THC lands between 15% and 20%, with low CBD. Dready also notes good bud size for a plant this tall. Dready calls the high very strong and uplifting, and the flavor follows a peppery citrus blend. For growers, the takeaway is space. This tall, sativa-leaning plant needs room overhead and a long season outdoors.
