Choosing seeds

Feminized seeds
When given less than 12 hours of light every day, feminized seeds bloom and produce weed. Gather either in the fall outside or indoors after around 15 to 20 weeks. Feminized strains are used by beginners & experienced growers and produce higher-quality buds than auto-flowering strains.

Automatic seeds
Easy to grow and simple plants can be cultivated from auto-flower seeds in just 10 to 14 weeks before they are ready to be picked. Fantastic for first-time cultivators, limited harvesting areas, and seasonal yields.

How to germinate

To ensure germination, immerse the seeds in a glass of water for at least 12-72 hours while keeping them in the dark at room temperature. When the whitetail appears, plant your seeds 1/2 inch deep in the soil or another medium that has been moistened. You should see a seedling emerge within 2 days after planting. Seedlings thrive in bright, sunny conditions (21°C to 23°C)

Mamba Negra won the 2014 ExpoGrow competition in the category of best Indica cannabis. One of the strains used to create this feminized, mostly Indica strain was Critical Mass. By selecting only the most potent Big Bud phenotypes, this strain has earned a well-deserved name in the cannabis industry. Red Haired Skunk was crossed with cannabis, known for generating incredibly huge blooms that can snap the branches in two, creating a hybrid with concrete in the flowery and fruity scent.

Growing Mamba Negra Seeds

This Skunk hybrid grows into a bushy strain that may reach a height of up to 3 meters while predominately an Indica strain. She may get too tall for her frame if raised in an enclosed space. Thus, she will need special training to prevent this. One large central cola and a few medium-length lateral branches emerge in Mamba Negra Feminized. The full size of her flowers and the appearance of brilliant orange hairs grouped in trichomes will take place around 8 to 9 weeks. Her fragrance is evocative of sugary confections, and she yields 500 g/m2 per square meter. As she reaches maturity, this female will display end-of-season hues, such as pinks and purples, with a THC content of 18%.

Mamba Negra Weed Flavor and Effect

The effects will be cerebral and corporeal, characteristic of a high-quality classic Skunk variety. Her 18% THC content is enough to offer you a cerebral boost for a fruitful brainstorming session or an in-depth conversation with pals. Perfect for daytime use because it won’t make you sleepy. You will enjoy walking, working out, making art, reading, and chatting with friends at local cafes.

The range of fruity and floral terpenes in Mamba Negra Feminized makes for a strain that is as sweet as it is potent. Patients suffering from depression, lethargy, lack of motivation or concentration, nausea, appetite loss, and anxiety may benefit from this Skunk hybrid strain of medicinal marijuana. If you enjoy exotic, fruity cultivars, you won’t find anything more pleasing than this one. Mamba Negra Feminized always delivers top-notch results, no matter the conditions.
