Black Mamba Auto CBD by Blimburn Seeds – High-CBD Autoflowering Strain for Balanced Effects

Black Mamba Auto CBD by Blimburn Seeds is a premium high-CBD autoflowering strain engineered for therapeutic use and effortless cultivation. With a balanced 80% indica / 20% sativa dominance and a rapid 8–10 week life cycle, it delivers consistent, non-intoxicating relief with a refreshing citrus and fruity flavor profile.

Are you struggling to find a strain that calms your mind without clouding it?

Most high-THC varieties leave you too zoned out to function, while weak CBD options barely make a dent in stress or discomfort. You want something reliable, fast, and effective—without the legal gray area or psychoactive side effects.

That daily grind, the muscle tension, the restless nights—they wear you down. You need a solution that fits into your routine, not one that disrupts it. Waiting months for harvest or dealing with finicky plants only adds stress, not relief.

Meet Black Mamba Auto CBD: the no-nonsense, fast-flowering strain designed for real life. With up to 12% CBD and less than 0.3% THC, it offers a clear-headed, uplifting experience that eases tension without sedation. Its autoflowering nature means you go from seed to harvest in just 8–10 weeks—no light schedule changes needed. Grow it indoors under 18–20 hours of light or outdoors in full sun, and enjoy dense, trichome-rich buds with a zesty citrus punch. It’s the smart choice for medical users, beginners, and anyone who values discretion and consistency.

Before growing Black Mamba Auto CBD

Before you start, you’ll want to set up a simple, stable environment. This strain thrives with minimal fuss, but a solid foundation ensures maximum resin and CBD production. Choose a spot with consistent light and good airflow—whether it’s a small indoor tent or a sunny balcony. Since it’s autoflowering, you won’t need to switch light cycles, but you will need to plan for its final size.

• Start with a final pot of 18–27 L (5–7 gal) to support root development
• Use well-draining soil or coco with added perlite for aeration
• Germinate seeds between moist paper towels at 22–25°C (71–77°F)
• Keep humidity high (60–70%) during the first week
• Choose a stable location—autoflowers hate being moved

During cultivation: watch it thrive

Black Mamba Auto CBD grows fast and steady, with a bushy, medium-height structure that responds well to light training. You’ll notice vigorous growth in the first few weeks, followed by a smooth transition into flowering—no stress, no guesswork. The plant develops dense, resinous buds with a strong citrus and fruity aroma, especially in the final stretch.

Keep daytime temperatures between 22–26°C (71–79°F) and nighttime temps 2–3°C (3–5°F) cooler. Reduce humidity to 50–60% during vegetative growth, then drop to 40–50% in flowering to prevent mold. Water when the top inch of soil feels dry, and avoid overfeeding—this strain prefers a light hand with nutrients. For stronger roots and better nutrient uptake, consider adding Root Juice BioBizz early in the cycle.

While it doesn’t need topping, gentle low-stress training (LST) can improve light exposure and yield. Avoid aggressive pruning—autoflowers don’t recover well. If you’re growing indoors, a quality LED like those in our grow shop ensures optimal canopy penetration and resin production.

After harvest: enjoy the results

Once harvested, you’ll be greeted with rock-hard, trichome-covered buds that smell like fresh tangerine and sweet skunk. Indoor yields reach up to 500 g/m² (1.64 oz/ft²), while outdoor plants can produce 600–700 g (21–24 oz) per plant under ideal conditions. The slow, careful drying and curing process—lasting at least four weeks—preserves the terpenes and enhances the smooth, flavorful smoke.

After curing, store your buds in airtight jars in a cool, dark place to maintain freshness and potency. Minimal maintenance is required—just clean your tools and sterilize your grow space to prevent pests and mold in future cycles.

Frequently Asked Questions

Is Black Mamba Auto CBD legal to grow?

Yes, in regions where high-CBD, low-THC cannabis is permitted. Always check your local laws before cultivation.

Can I grow this strain outdoors in colder climates?

Yes, but for best results, grow it in spring or early summer when temperatures are consistently above 15°C (59°F). Use a greenhouse or cloche for added protection.

How do I maximize CBD content in my harvest?

Allow the plant to fully mature—harvest when trichomes are milky-white. Avoid early harvesting and ensure a slow, dark curing process of at least four weeks.

Does this strain require special nutrients?

No, but it benefits from a balanced, mild nutrient regimen. Overfeeding can reduce terpene production. Consider using organic supplements like Top Max BioBizz during flowering for enhanced resin and flavor.

Is it suitable for making extracts?

Absolutely. Its high resin production and rich terpene profile make it ideal for CBD oils, edibles, and concentrates.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown dozens of CBD strains, but Black Mamba Auto CBD stands out for its reliability and flavor. I started with six seeds in 20L pots using a coco-perlite mix—no fuss, no failures. I kept the light cycle at 20/4 and used Root Juice BioBizz from day one, which gave me strong, white roots by week two.

The stretch was moderate, and by week four, I did a light LST to open up the canopy. No topping—autoflowers don’t forgive mistakes. I switched to bloom nutrients at week five and added Top Max BioBizz in the final three weeks. The smell was intense—like citrus peel and tropical fruit—so I ran a carbon filter.

Harvested at nine weeks with fully milky trichomes. After a 14-day dry and four-week cure, the buds were dense, frosty, and smooth to smoke. The effect? Clear, calm, and focused—perfect for evening wind-down without drowsiness. If you want a no-stress, high-CBD grow that actually delivers, this is your strain.
