Black Jack Feminised Seeds

Black Jack is an exceptional plant with a very special Jack Herer pheno-type resulting from the cross of Black Domina.

It's a 50/50 sativa/indica plant. As well as being a very highly productive cannabis strain, it is very powerful.

Black Jack is a great plant for any indoor garden and any method or substrate, although, having said that, when supplied with sufficient sunlight, it also performs wonderfully well outdoors.

This rules out any region with a cooler climate than that of the Mediterranean type.

Although the height achieved by indoor plants will largely depend on the length of the vegetative growth period, those cultivated outdoors can reach a magnificent 300 cm. tall.

When presented with the opportunity, plants can really spread out and can resemble a spherical form with its plethora of side branches.

Indoor yields are very good and, in 9 weeks of flowering, growers can expect to harvest between 500 - 600 gr/m2.

Outdoor harvesting in the northern hemisphere will take place during the first two weeks of October, which in warm climate regions should not present a problem with adverse weather conditions and the yield per plant is expected to be between 500 and 700 gr.

Black Domina's sweet aromatic qualities serve to temper and soften the Jack Herer's scent of incense.

THC production is high to very high and has been measured with approximately 0.6 percent CBD at 16 percent - 21 percent.

For parties and other social occasions, the effect is euphoric and happy and is said to be a great selection.
