Nirvana Seeds comes under the arm with one of the most exciting new features of the last five years, Blackjack! In its birth, Black Domina and a Jock Horror have participated, achieving a genetic cocktail of the highest level that will surely leave every smoker who tries it stunned.

What does Blackjack cannabis plant look like?

These seeds produce sativa-dominant plants, with the typical columnar and branching structure that needs space to develop fully and if you neglect it can be a problem if you decide to grow it indoors. Its leaves are thin and serrated, standing out for its aromatic quality that invades the room from very early.

What does Blackjack variety taste like?

A true madness, this strain will leave your taste buds in a complete state of shock. Its nuances are sweet and citrus, with some earthy and pine touches that put the icing on the cake.

What effect does Blackjack have?

Its effect as a good sativa is enlightening, happy and causes a fun and uncontrollable verbiage. A great choice if you want to have a good time with friends and leave aside the bad vibes.

How to grow Blackjack variety?

Under the bulbs, it has to be controlled so that its growth does not spurt out and can be a problem. To do this, pass it soon to 12 hours of light, maximum at 20 days of growth, as in flowering can double its size. With pots of 2.4 US gal (9 liters) and 11 copies per 3x3ft (m2), you can cut between 15.8 and 19.4 oz per 3x3ft (450-500 grams per m2). To get the best performance, I recommend applying a SOG culture, taking full advantage of the large central tail that forms.

Under the sun, it is a plant that wants to be cultivated directly on the ground or in a big pot, minimum 13.2 US gal (50 liters) if you choose this last option. With a substrate with coconut fibre, you will contribute to a wider root development than supported with Roots Excelurator, you will see how the development of the plant is vigorous and the productivity can reach 22.9 oz (650 grams) per plant.

A smoke with Nirvana Seeds' Blackjack and... Hakuna Matata, live and be happy!
