Why this one matters: hybrid genetics with a 25% THC ceiling and pine/sweet-led terps. 7-9 weeks flowering, indoor or outdoor.

Smell-first: crack a dried bud and the room fills with sharp pine and a clean sweetness that lingers longer than you'd expect from a 7–9 week flowering window. Black Mamba from Amsterdam Seeds Company runs 60% indica dominant, and at 25% THC it hits firmly in the upper range without requiring exotic growing conditions to get there.

Indoors it tends to top out around 100–160 cm, so standard tent setups handle it without much canopy management. Yields sit at roughly 450 g/m² when environmental basics — VPD, light intensity, feed schedule — are dialed in. It's not a beginner strain; expect to manage moderate stretch during the first few weeks of flower and watch run-off EC if you're pushing nutrients. That said, it's not temperamental enough to punish growers who haven't hit master-level yet.

Best suited to intermediate cultivators who want a reliable photoperiod feminized plant and don't need to babysit every variable.

Genetics & Lineage

Black Mamba traces its genetics to 60% Indica/40% Sativa (Amsterdam Seeds Company). This hybrid-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Amsterdam Seeds Company, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 25%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Black Mamba delivers THC levels of 25%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing Black Mamba

Black Mamba is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 7-9 weeks with yields of 450g/m2. Plants typically reach 100-160cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Black Mamba features a pine, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Black Mamba is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
