Description
Black Jack Feminised from Sweet Seeds brings together two pillars of cannabis genetics: the dense, resinous structure of Black Domina '98 and the legendary, spirited character of Jack Herer. The result is an indica-sativa hybrid carrying THC levels of 16 to 24%, with an aroma built around pine, warm spice, and dry wood. Effects lean into that hybrid balance, offering both presence and clarity in a single session.
In the garden, Black Jack is a photoperiod feminised strain that rewards growers who give it room to perform. Plants stretch large, so vertical space is worth planning for, whether in a tent or a greenhouse bay. Indoors, expect yields of 450 to 600 g/m2 across a 9 to 11 week flowering window, a timeline that suits most indoor schedules without demanding a rushed finish. Outdoor plants are genuinely productive, capable of reaching 450 to 750 g per plant under a generous season. This is a straightforward, high-return cultivar from Sweet Seeds that repays attentive growing with a substantial, quality harvest.

FAQ
All you need to know
about this product
Black Jack Feminised from Sweet Seeds combines legendary Black Domina and Jack Herer genetics, delivering resinous, high-yield harvests ready for growers who take their craft seriously.
Black Jack sits in genuine hybrid territory, blending the grounded weight of Black Domina with the uplifting clarity Jack Herer is known for. The result is a well-rounded session that carries both relaxation and a sense of presence without tipping too far in either direction. THC runs between 16 and 24%, so the experience has real potency behind it.
The aroma is built around pine, dry wood, and a layer of warm spice that becomes more pronounced as flowering progresses. It's a classic, resinous scent profile that reflects the depth of its Black Domina heritage rather than anything sweet or fruity. Expect that character to carry through to the finished product.
Black Jack is rated moderate to advanced, so it's best suited to growers who already have a few successful grows behind them. The plants stretch large and need thoughtful management of vertical space and canopy, which can challenge those still learning the basics. Intermediate growers willing to plan carefully will find it very rewarding.
Indoors, Black Jack consistently delivers 450 to 600 grams per square metre, with outdoor plants capable of 450 to 750 grams each given sufficient space and light. The 5+2 pack from Sweet Seeds means you receive seven feminised seeds at the five-seed price, giving you two extra plants to work with or keep as backups — solid value for a strain at this performance level.
