The development of Black Mamba #42 feminized seeds began with one specific intent: to find a phenotype unlike anything else on the market. Years of breeding and testing followed—one phenohunt after another—in search of the “black” phenotype we could lock into the plant’s DNA. Plant #42 was different. Out of the entire Black Mamba selection, it was #42 that carried what we were looking for: deep, near-total black pigmentation expressed consistently throughout every stage of growth, regardless of temperature. That plant became the foundation of everything that followed.

Two Recognizable Parents

To take Black Mamba #42 where it needed to go, the genetics had to be right from the start—and that meant working only with parents that had already proven themselves over time. The female parent was Morositax from Art Genetix. A cross of Gorilla Glue #4 and Platinum Cookies F2, it provided exactly what we were looking for: structural density, extreme resin production, a predisposition toward dark pigmentation, and a cookie-sweet terpene layer beneath the berries. Crossing Morositax with Blueberry by DJ Short—an anthocyanin-rich classic from the archive—made it possible to stabilize the black coloration as an inherited genetic trait while adding the signature fruit flavor that defines the profile.

Black Gem in Any Room

Many “dark” strains develop their color when temperatures drop during the final weeks. Black Mamba #42 carries it in its DNA. By day 30 of flowering, the foliage ranges from deeply dark to nearly black across the fan leaves, sugar leaves, and buds, with red and burgundy stems running through the canopy. That visual consistency is what makes Black Mamba #42 feminized seeds worth growing beyond the effect: the plant is genuinely striking. The plant is compact and well-branched, with multiple stacked bud sites along the main cola and lateral branches. It fills a tent efficiently without requiring unusual vertical space. Its dense bud structure and high resin production require careful attention to airflow and humidity during the final weeks of flowering—standard precautions for a dense, high-resin photoperiod plant. Yield runs 500–600 g/m² over 8–9 weeks of flowering. The growing difficulty is moderate—manageable for anyone with a few grows behind them, although the bud density deserves close attention.

Fingers Won’t Let Go

The resin load on Black Mamba #42 is the kind you notice the moment you touch a late-flowering bud: sticky, immediate, and heavy with terpenes. The fragrance combines blueberry and sweet berries with a cookie undertone. Tropical in character, it carries through to the taste and lingers. The flavor leans toward sweet berries and blueberry pie, staying on the palate long enough to make this strain particularly memorable for growers who prioritize taste.

Strikes Like a Mamba

Like its namesake, the effect arrives quickly: body-forward and decisive. It begins with euphoria and a creative lift, then settles into strong physical relaxation and calm. THC runs 20–25%, and the Indica dominance becomes clear in the second half. This is a late-evening strain that works best when there are no plans for the rest of the day.
