Smell-first impressions from this one lean citrus-forward with a skunk backbone that sharpens late in flower — not a delicate nose, but a memorable one. Mamba Negra CBD Auto from Blimburn Seeds sits in a useful middle range: THC tests consistently at 20–25%, which is high enough to feel substantial, yet the autoflowering structure keeps the grow manageable without demanding expert-level dialing. Plants wrap up in 8–10 weeks from seed, and indoor growers running a solid setup regularly pull 400–500g/m² without heroic effort.

The moderate difficulty rating is honest — you'll want some basic feeding discipline, but there are no notoriously fussy phenotypes to sort through. The compact autoflower frame makes it workable in smaller tents or mixed outdoor spaces where headroom is limited. Best suited to growers who want meaningful THC output in a fast turnaround without committing to a long photoperiod cycle.

Growing Mamba Negra CBD Auto

Mamba Negra CBD Auto 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 8-10 weeks with yields of 400-500g/m2. Plants typically reach 60-100cm indoors.
