Mamba Negra FBV delivers resin-heavy buds, a bold citrus-fruit aroma, and a deeply relaxing indica character on a fast flowering schedule. With 80% indica and 20% sativa genetics, it brings a calm, heavy finish and impressive yields in a compact growing window.
This fast-flowering variety comes from Mamba Negra crossed with a Secret Hybrid. Mamba Negra traces back to Critical Mass and Skunk, bringing sturdy growth and strong production to the mix. The result blends American and European genetics into a resilient plant with 15–19% THC.
The aroma opens with bright citrus and ripe fruit, then settles into a rich, woody finish. Expect dense, rock-hard flowers dressed in a thick coat of sparkling trichomes. Each draw carries that vivid fruit-and-wood character in a smooth, flavorful smoke.
Mamba Negra FBV offers a medium-THC experience with a pronounced indica feel. Calm, relaxed effects ease in gradually, with a sleepy finish that suits quiet evenings after a demanding day. Its balance of body-heavy comfort and clear-headed composure makes it a rewarding choice for winding down.
Myrcene lends the profile an earthy depth, while linalool adds a soft floral note and geraniol brightens the aroma with a citrus-floral lift. This terpene-rich variety suits evening sessions and growers seeking resin-packed flowers for concentrates. Its traditional use appeal includes relaxation and winding down before sleep.
These are fast-flowering seeds, not autoflowers. Plants typically finish flowering in 6–8 weeks, with many crops ready in about 6–7 weeks under suitable conditions. Mamba Negra FBV is beginner-friendly and grows indoors or outdoors. Every Grassfarmer seed comes with a germination guarantee.
Early growth rewards a clean, steady setup. Use quality soil or a well-draining coco-based medium, and keep young plants supplied with appropriate nutrients as they establish. Indoors, a ScrOG setup can help spread the canopy and give lower branches more access to light.
Plants grow to around 1.5 m and develop a sturdy central stem with productive side branches. Aim for consistent airflow and plenty of light. Temperate conditions suit this variety, with daytime temperatures around 70–80°F (21–27°C). Keep humidity controlled and lower it as flowering progresses to help protect dense buds.
At harvest, expect high yields and resin-rich flowers. Indoor growers can target 500–600 g/m², while outdoor plants can produce around 400–700 g each in favorable conditions. Outdoor harvest timing varies by location and season, so follow local growing rules and monitor plant maturity closely.
