About Mamba Negra Seeds


Mamba Negra is one of the many products of Blimburn Seed Bank based out of Barcelona, Spain. The strain was made possible by advanced genetic engineering, breeding the award-winning Critical Mass with Red Haired Skunk. As a result, we are blessed with an incredible cultivar in Mamba Negra, a reference to a highly venomous snake from sub-Saharan Africa, which was also the inspiration by one of the greatest, fiercest competitors in NBA history, Kobe Bryant.

The strain has grown to incredible popularity in the United States thanks to its fruity flavor, resilient genetics, and high THC content. Mamba Negra is an excellent option for first-time growers, as it is resistant to pests and mold and will deliver in nearly all climates.

Growing Mamba Negra Seeds

Cultivating Mamba Negra is ideal indoors and outdoors. In addition, the strain will suit your growing abilities regardless of your experience level. Part of the reason the cultivar has become so popular is its low barrier to entry while still producing high yields and an impressive cannabinoid and terpene profile.

Mamba Negra’s popularity has caused the genetics to carry on to more advanced varieties, including:

  • Feminized Mamba Negra Seeds – The option is true to the genetics, but you won’t have to weed out the male plants.
  • Mamba Negra Autoflower Seeds – Auto seeds will flower in as little as two weeks, and you won’t have to worry about switching your lighting schedule.
  • Mamba Negra CBD and CBD Auto – The strain has been genetically modified to produce a high concentration of CBD.
  • Mamba Negra Fast Blooming – The original strain was crossed with a hybrid to expedite the flowering time.
  • Mamba Negra CBG – Experience the legendary strain with an impressive level of CBG content.

Grow Difficulty

Mamba Negra seeds are one of the best options to help you build your experience if you are just beginning your journey as a cultivator. The strain is highly resistant to pests and mold and can thrive in just about any environment.

While Mamba Negra cannabis plants are highly resilient, we recommend following several minor requirements if you want to maximize the strain’s potential. Keep our cultivation tips in mind when growing Mamba Negra, and you’ll easily produce an impressive harvest of oversized, cannabinoid-rich buds.

Optimal Growing Conditions and Climate

Like all premium cannabis varieties, Mamba Negra requires a controlled environment to reach its full potential. Because of its sturdy genetics, your margin of error is far greater than other, more difficult strains to cultivate; however, that doesn’t mean you should neglect the growing environment.

Keep your temperature between 75°F and 80°F, with the humidity around 40% once the plants reach the vegetative stage. We recommend slowly increasing the humidity as your plants mature, with the humidity levels hitting around 50% into late bloom.

Mamba Negra seeds naturally produce large buds, putting significant stress on the plant’s branches. Therefore, we recommend implementing the Screen of Green (ScrOG) method to mitigate a heavy flower.

How to Use the ScrOG Grow Method

The Screen of Green (ScrOG) method is a cannabis cultivation technique that uses a screen or mesh placed above the plants to train them to grow horizontally and fill in the entire screen area, creating a dense canopy. This allows for more even light distribution and can increase yields.

Here are the instructions on how to use the ScrOG method:

  • Obtain a screen or mesh that is the correct size for your grow space and plants. Nylon mesh is the most commonly used material, but other materials can also be used.
  • Place the screen above the plants at an early stage of growth, usually when the plants are around 2-4 inches tall.
  • Train the branches to grow through the mesh by gently bending and tying them down to the screen as they grow.
  • Make sure to keep the screen and plants clean, trimming any leaves that grow through the screen and removing any dead or yellowing leaves.
  • The plants should fill the screen as they grow, creating a dense canopy.
  • Once the plants reach maturity, carefully remove the screen to harvest your buds.

It’s important to note that this method demands consistent training, pruning, and maintenance throughout the growth cycle.

Feeding Mamba Negra Seeds

Growing Mamba Negra seeds is a relatively easy task if you understand the plant’s genetic profile. The combination of Critical Mass and Skunk makes it a highly nutrient-dependent variety in its early stages of development. To accommodate the plant’s hunger, we recommend a heavy feeding schedule immediately after your seeds are germinated.

Follow the instructions from your favorite NPK nutrient manufacturer but don’t be afraid to go a little on the heavy side with Mamba Negra. The plants need a nutrient-rich environment in veg to develop the strain’s signature massive buds.

If you want to keep your grow organic, here are some alternative, all-natural fertilizers for the primary nutrients.

Nitrogen – manure, blood meal, coffee grounds, worm castings
Phosphorus – rock dust, bone meal
Potassium – kelp meal, greensand, hardwood ashes

Many organic cannabis farmers also use dolomite lime for its high concentration of calcium and magnesium.

Flowering Time

Mamba Negra is known for its relatively short flowering time, typically taking 8-9 weeks to reach maturity. This makes it an excellent option for growers who want to harvest their buds quickly and those with limited growing space.

During the flowering stage, the plants will produce massive resinous buds packed with cannabis compounds. The buds will be large, dense, and sticky. We recommend adding branch supports to accommodate the oversized buds if you don’t plan on implementing the ScrOG method.


Mamba Negra plants will deliver high yields even if you are new to growing cannabis, with the potential to produce up to 450-500 grams per square meter when grown indoors and up to 600 grams per plant when grown outdoors. However, it’s important to note that yields depend on the work done during the growing process. A well-maintained and properly cared for Mamba Negra plant will yield more flower than a neglected plant.

Outdoor growing will generally deliver higher yields, but indoor grows will generate more cannabinoids and terpene production. This is because indoor growing allows for more control over the environment and the use of specialized equipment, such as LED lights, to enhance the growing process.


If you are looking to grow towering plants, Mamba Negra probably isn’t the best option. With heights around 4-5 feet, the variety isn’t being vertically gifted. As a result, the strain is a prime candidate for the ScrOG method.

Resistance to Pests and Mold

While Mamba Negra is a highly resilient strain had will naturally fend off most pests, mold, and mildew, we highly suggest taking the following precautions when growing outdoors.

  • Use diatomaceous soil, a powerful natural insecticide, to ward off pests.
  • Prevent Thrips by using foliar insecticide.

Strain Description and Properties

Mamba Negra is known for moderate to high THC content, with an average of around 20%, with the potential to hit 25%. While this isn’t as high as many of the designer cultivars in the modern cannabis industry, the total compounds produced by the strain’s flowers make it a highly sought-after variety.

Dominant Terpenes Found in Mamba Negra Seeds

Mamba Negra is rich in terpenes, particularly Limonene, Myrcene, and Caryophyllene, which contribute to the strain’s unique aroma and flavor. Below is a short description of the potential benefits of each of the popular aromatic oils found in the strain.

Effects of Mamba Negra

Mamba Negra is a potent strain that can produce strong, euphoric effects. While the combination of the award-winning Critical Mass and Skunk undoubtedly birthed an indica-dominant phenotype, the high is balanced in relation to the entire experience.
