Breeder: Nirvana Seeds
Blackjack is highly resilient to cold and wet weather, making it perfect for outdoor grows in locations with short summers.
Blackjack also has a low profile, making it ideal for those outdoor growers who need discretion and want a fast blooming strain.
Blackjack exhibits true hybrid vigour, with bold earthy and pungent flavours that produce an exhilarating high.
It is a fine blend of Indica and Sativa genetics that takes between 8 & 9 weeks to flower.
However, only growers with experience growing Sativas and other more challenging cultivars, are recommended to cultivate Blackjack.
It is a low profile plant that is perfect for those who take the time to train their plants.
