Mamba Negra brings award-winning indica character to your grow. A 55% indica, 45% sativa blend, it pairs bold citrus-fruit flavor with resin-heavy flowers and a relaxing, uplifting experience. This ExpoGrow 2014 Best Indica winner delivers standout genetics in a dependable feminized seed.

Our breeders created Mamba Negra from Critical Mass × Skunk, drawing on sturdy, well-loved indica and Skunk heritage. The result is a balanced hybrid with a compact, robust structure and a celebrated European pedigree.

Expect a bright citrus opening followed by juicy, fruity notes. Dense buds develop a generous coating of aromatic resin, making this variety a flavorful choice for flower and a strong option for extract enthusiasts.

At around 18% THC, Mamba Negra offers a potent yet approachable profile. Its effects combine physical relaxation with a euphoric lift, an uplifted mood, and a spark of creativity. It suits a laid-back evening when you want to unwind and stay engaged.

Alpha- and beta-pinene, borneol, caryophyllene, geraniol, humulene, linalool, and myrcene shape its terpene profile. The citrus-forward aroma and soothing character make Mamba Negra a compelling pick for growers seeking expressive flavor and a relaxing finish.

These feminized seeds are bred to produce female plants for flower production. They’re suitable for growers at every experience level, with hardy genetics and a flexible indoor or outdoor grow. Germination is guaranteed, so you can start with confidence.

Give seedlings a quality, well-draining medium such as coco, peat, or a blend enriched with perlite. Provide steady light, balanced nutrition, and warm, stable conditions. Start with attentive pest prevention, then guide healthy growth with consistent care.

Mamba Negra adapts well to different growing methods and rewards a well-managed canopy. Indoors, a ScrOG setup can help spread growth evenly and bring light to lower sites. Maintain airflow and manage humidity as plants develop, especially once flowering begins.

Flowering takes approximately 8–10 weeks indoors, with yields reaching up to 500 g/m² in favorable conditions. Outdoors, plants can produce around 600–700 g each, with harvest typically in October. Expect dense, resin-rich flowers and a rewarding crop from this resilient variety.
