Blackjack - Nirvana Seeds

Blackjack by Nirvana Seeds

Blackjack by Nirvana Seeds combines Black Domina with Jock Horror in a sativa-dominant hybrid with an unusually compact plant structure. The line remains considerably shorter than many traditional sativa varieties and develops short internodes with broad, bushy side branches.

After stretching, Blackjack reaches approximately 100 cm. The plants respond well to low-stress training and Screen of Green, allowing the vigorous side branches to be distributed evenly across the available area. Individual branches may also benefit from support when flower production becomes heavy.

Flowering takes approximately 8-9 weeks. Nirvana lists indoor yields of 400-500 g/m². Outdoors, plants may produce up to 650 g each under suitable conditions, with harvest expected around early October.

The aromatic profile combines earth and citrus with spices, lemon and a strongly pungent base. Nirvana identifies humulene, caryophyllene and pinene as the dominant terpenes. The resilient line is also described as resistant to changing weather, heat, mold and mildew.
