Black Jack


By crossbreeding Black Domina’98 and an exceptional Jack Herer that has a very pleasant and intense bouquet, the breeders at Sweetseeds obtained this new variety. Black Jack Cannabis Seeds from Sweet Seeds! Available now at the HollandsHigh Seedstore!

You can count on Black Jack® to be one of the most potent and productive strains in the entire range.
Her great hybrid vigor makes her fully suitable for indoor growing. Planted outdoors, in open soil and, with sufficient sunlight, this sturdy lady becomes a hairy resinous monster that can reach up to three meters in height. If you feel like bragging about a giant plant, then Black Jack is definitely suitable.

Growing Black Jack

Black Jack won more than ten prizes and was even awarded the main prize three times. With her 1:1 genes of Indica and Sativa, this lady has inherited the best qualities of both and it shows in the shape and position of the leaves. If you don’t top the plant at the beginning of the growth phase, she will develop one huge main cola and numerous sturdy side branches.

Flowering Black Jack

During flowering she will produce 16 to 21% THC and 1% CBD in her buds, which is quite high. You can expect a harvest of 5 to 600 gr/m² indoors and if you have the plants in open soil, you can easily count on 500 to 700 gr/plant.

Flavours of Black Jack

This strain is a delight to smoke and her aromas and flavors are distinctly good for people who like citrus. And, even though this taste is subordinate to the woody and earthy flavors, citrus still completes the pallet.

Effects of Black Jack

The high THC content will not deter users of Black Jack from smoking or vaping her during the day as it is a type of weed that has a stimulating effect. Both physically and mentally, BJ won’t throw you on the couch or make you buzzy and you can easily get through the day. Beginners should be careful if they are not used to using a THC-rich strain.
