Black Jack by Sweet Seeds genetics

Black Jack combines two genetics to create a hybrid of unique potency and aroma:

• Black Domina: Brings rapid flowering, a sweet aroma base and dense bud structure, offering a velvety touch to the profile.
• Jack Herer: Contributes Sativa vigour, the production of large branches and, most importantly, its distinctive and penetrating cathedral incense or Haze aroma.

The result is a robust and productive plant, ideal for those seeking cannabis seeds of high quality with a balanced effect.

What is the taste of Black Jack weed?

The organoleptic properties of Black Jack are its greatest hallmark. Its taste and aroma are intense and very complex:

• Dominant note: Aroma of cathedral incense Haze-type, penetrating and long-lasting, a direct heritage from Jack Herer.
• Base note: A touch of sweet and earthy aromas, from Black Domina, which round out and soften the Haze profile.

This combination makes cannabis Black Jack a strain with exquisite taste, highly appreciated by lovers of classic incense flavour.

What are the effects of Black Jack seeds

The effects of this cannabis variety are the result of its perfect genetic balance (50/50):

Black Jack by Sweet Seeds: customer reviews

Our customers have very positive opinions of this Black Jack seed variety. Here we reveal the strongest and highest-rated points:

• Distinctive taste: The cathedral incense Haze-type aroma and taste is the most praised feature. It's described as intense, pleasant and with sweet undertones that soften it.
• Perfect balance: Users love the mixed and very balanced effect (50/50): a cheerful, euphoric and psychoactive head high, combined with powerful physical relaxation thanks to Black Domina.
• Enormous plant: Outdoors, Black Jack becomes a "resinous and hairy monster" that can reach or exceed two metres in height if planted in soil.
• Easy: It's a robust and stable plant, tolerating beginner grower oversights well and has become the "most iconic variety" for some customers.
• High resin production: The buds are "full of resin" and even the leaves are covered, making it exceptional for powerful extractions.
• Strong smell: One point to consider is that the aroma during flowering is extremely strong and penetrating, noticeable "miles away", so it may require powerful ventilation systems and filters indoors.
