Black Jack is an exceptional plant that resulted from a cross of Black Domina with a very special Jack Herer pheno-type. It is a 50/50 indica/sativa plant. It is both very powerful as well as being a very highly productive cannabis strain. Black Jack is a superb plant for any indoor garden and any method or substrate although, having said that, it also performs wonderfully well outdoors when supplied with sufficient sunlight. This rules out any climate region that is cooler than that of the Mediterranean type. While the height attained by indoor plants will depend largely on the length of the period of vegetative growth those which are cultivated outdoors can reach a magnificent 300 cm. tall. Plants can really spread out when presented with the opportunity and can resemble a spherical form with its plethora of side branches. Indoor yields are very good and growers can expect to harvest between 500 - 600 gr/m CBD in 9 weeks of flowering. Outdoors harvest in the northern hemisphere will be during the first two weeks of October, which should not present a problem with adverse weather conditions in warm climate regions and the yield per plant is likely to be between 500 - 700 gr. The sweet aromatic qualities of Black Domina serve to temper and soften the incense aroma of the Jack Herer. THC production is high to very high and has been measured at 16% - 21% with approximately 0.6% . The effect is euphoric and happy and is said to be a great selection for parties and other social occasions.
