All about Mamba Negra
Mamba Negra developed by GB Seeds is a spectacular variety born from the spectacular cross between two legends in cannabis’ scene: Critical and Skunk. This genetic, winner in multiple Cannabis Cups, stands out for the huge amount of compact flowers, its citric and fruity aroma and as well as for its effects suitable for all consumers.
Mamba Negra effects
Mamba Negra offers a balanced experience starting with a psychoactive high that will little by little turn into an intense physical relaxation. Its therapeutic properties make this strain perfect to fight against stress and to improve sleep quality, consequently it is recommended to enjoy it late in the afternoon or just before going to bed.
The THC levels that Mamba Negra has ranges between 20-25%, being ideal for beginner consumers looking to increase their tolerance and for the more experienced ones searching for a moderate and balanced potency.
Mamba Negra flavor and aromas
Regarding its organoleptic characteristics, Mamba Negra pops out because of its strong citric flavor, mixed with fruity and sweet notes. The big amount of limonene and linalool generates stimulant properties.
On the other hand, it is necessary to emphasize its strong odor, so it will be necessary to install anti-odor filters or ozone generators to maintain caution and not to attract the attention of your neighborhood or third parties.
How to grow Mamba Negra indoors
Mamba Negra develops plants with vigorous growth, large branches and a larger internodal area than classic indica varieties due to its 40% sativa. For this reason, indoors it is advisable to carry out training such as SCROG to control its height and maximize production.
This variety, in optimal conditions, is an excellent producer. In fact, it is capable of generating between 400 and 500 grams per square meter to be harvested after 63-70 days of flowering.
How to grow Mamba Negra outdoors
Outdoors, Mamba Negra is capable of reaching heights of up to 2 meters with an imposing structure. Due to the large size of its flowers, it is recommended to use tutors to avoid branches from bvreaking. On the other hand, to reach its full potential, a quality soil, a quality fertilization program and a sunny location are required.
By following the above tips, and with the help of some training such as apical pruning, it is possible to obtain a kilogram of hard buds for each plant. Finally, you will be able to harvest your spectacular haul in mid/late October.

I have 3 outdoors and I have to say the smallest one is two meters tall!! It's amazing the strength with which they grow if you give them what they need, eagerly waiting for those rock-hard buds

Good strain?? I put 1 to test in an 11-litre pot and it turned out very good despite running low on nutrients due to limited root space, I already ordered more and now the next ones I'll set up properly in 46-litre buckets, they look like heavy yielders...
Translated from Spanish
Buena variedad?? puse 1 para probar en una maceta de 11 litros y salio muy buena a pesar de quedarse corta de nutrientes por el reducido espacio de las raices, ya pedi mas y ahora las siguientes ya las pondre bien en cubos de 46 litros, tienen pinta de ser buenas productoras...
