Mamba Negra feminized seeds by Blimburn Seeds give you a high-yielding, award-winning cannabis experience with minimal effort. This 55% indica hybrid packs a flavorful punch and delivers a balanced, uplifting high—perfect for winding down or sparking creativity.
Struggling to find a strain that actually relaxes your body without locking you to the couch? You’ve tried indicas that knock you out, sativas that leave you anxious, and hybrids that just don’t deliver. The search ends here.
Most so-called relaxing strains either sedate you completely or fizzle out too fast. Ignore them, and you’ll keep battling stress, fatigue, and uninspired evenings. But Mamba Negra? It’s the Goldilocks of cannabis—just right.
With Mamba Negra feminized seeds, you get a perfectly balanced experience: deep physical relaxation paired with a clear-headed, euphoric buzz. No fog, no crash—just smooth, lasting calm and creative energy. It’s the strain that actually lets you unwind while still enjoying your night.
Yes. It’s forgiving, resistant to pests, and grows uniformly—perfect for first-time growers.
8–10 weeks indoors. Outdoors, harvest in late September to early October in the Northern Hemisphere.
Yes, it has a strong citrus-fruity aroma. Use a carbon filter like Advanced Hidtoponics Staters Kit to stay discreet.
It prefers warm, stable climates. In cooler zones, grow in a greenhouse or choose a shorter-season strain.
I grew Mamba Negra last season in my 1.2 x 1.2 m tent with a 600W LED. I used the SCROG method, and by week 6, the canopy was solid. The smell hit hard by week 3—citrus with a skunky edge. I had to run my carbon filter 24/7.
Harvest came at 9 weeks. I got 520 g/m²—dense, resinous buds with red hairs and a crystalline coat. The high? Smooth as hell. Body melt without mental fog. I shared some with friends after dinner, and everyone said it was the perfect 'chill but chat' strain.
Downsides? The buds are so heavy they need support. And don’t skip the flush—7 days minimum. But honestly, it’s one of the most reliable indicas I’ve grown. I’ll definitely be rotating it in every autumn cycle.
