Black Mamba #42 feminized started with a specific intent: to find a phenotype unlike anything else on the market. Years of breeding and testing, phenohunt after another to find that «black» pheno that we can lock into the plant’s DNA.
Plant #42 was different. Out of the entire selection run for Black Mamba, it was #42 that carried what we were looking for — total, deep black pigmentation expressed consistently across all growth stages, independent of temperature. That plant became the foundation of everything that followed.
To get Black Mamba #42 to where it needed to be, the genetics had to be right from the start — and that meant working only with parents that had already proven themselves over time. The mother’s plant came from Art Genetix breeders: their strain Morositax. It’s a cross of Gorilla Glue #4 and Platinum Cookies F2 — was exactly what we were looking for: structural density, extreme resin output, dark pigmentation predisposition and the cookie-sweet terpene layer underneath the berries.
Crossing it with Blueberry (DJ Short) — one of the most anthocyanin-rich classics in the archive, made it possible to lock in the black coloring as a constitutive genetic trait and deliver the signature fruit flavor that defines the profile.
Most “dark” strains color up when temperatures drop in the final weeks. Black Mamba #42 feminized has it in its DNA. What you notice first in the garden is that this plant doesn’t look like the others. The foliage runs from deep dark to near-total black on 30 days of flowering across fan leaves, sugar leaves, and the buds themselves, with red and burgundy stems running through the canopy. That’s what makes Black Mamba #42 feminized worth growing beyond the effect: the visual is consistent and it’s genuinely striking.
The structure is compact and well-branched, with multiple stacked bud sites along the main cola and lateral branches — a plant that efficiently fills a tent without requiring unusual vertical space. The dense bud structure and high resin production require attention to airflow and humidity in the final weeks of flowering — standard precautions for any high-resin photoperiod plant. Yield runs 500–600 g/m² over 8–9 weeks of flowering.
The difficulty level of growing is medium — manageable for anyone with a few grows behind them, but the bud density is worth paying attention to.
The resin load on Black Mamba #42 feminized is the kind you notice the moment you touch a late-flowering bud — sticky, immediate, and heavy with terpenes. The fragrance is blueberry and sweet berries with a cookies undertone, tropical in character, and it carries into the taste with real persistence.
Sweet berries and blueberry pie, with enough flavor staying on the palate after the smoke, so that growers who prioritize taste tend to remember this one specifically.
The effect hits with the same character as the mamba — fast onset, body-forward, and definite. Strong physical relaxation paired with an initial euphoria and a creative lift that eventually gives way to calm. THC runs 20–25%, and at that level, the indica dominance becomes clear in the second half. Growers report using it for stress and pain relief, and as a sleep aid. This is a late-evening strain that works best when there are no plans for the rest of the day.
