Black Domina ’98Jack Herer
A powerful strain, winner of numerous awards
We have crossed-bred our Black Domina with an exceptional Jack Herer of pleasing and intense aroma similar to the haze’s cathedral incense. The result is one of our most powerful and productive plant.
This variety produces long side branches and plenty of abundant resinous buds, giving the plant a shape similar to a sphere. This cross provides the plant a sweet aroma characteristic of Black Domina that softens the deep incense aroma of our Jack. It features the great vigor of a hybrid, totally adapted to indoor conditions. Planted outdoor directly in the ground and with enough sunlight it becomes a resinous and hairy monster of about 3 meters of height.
