★ This comment is connected to a BlackJack review! ★
Seed germinated easily via the paper towel method then inserted into a top-fed DWC hydroponics setup under a 600W light. Plant was topped 3 times in the vegetative stage, leaving 8 main colas. The BlackJack plant responded to training like a champ.
After changing light schedule to 12-12 for the flowering stage, the plant stretched quite a bit, though responded well to supercropping. She seems to be a slow starter in flowering. At first I was disappointed because the buds seemed to be very thin and forming slowly. By the end of flowering stage, I realized that they had fattened up considerably, and due to the stretch, the 8 main colas were nearly a foot long. The long colas had more fan leaves than normal, and at first they sort of hid how big the buds were getting.
She was sensitive to high levels of nutrients and got nute burned until I nearly halved my normal level of nutrients. Once given lower levels of nutrients, she started sparkling right up. Trichomes everywhere - all over the sugar leaves, under the leaves, and all along the stems. I»ve never seen a plant so frosty.
The buds are quite a bit thinner than some of the other big producing plants, but are consistent and well formed which made them easy to dry/cure. Buds have a very nice smell to them, almost flowery, not skunky at all, and buds were described as cerebral and anti-anxiety, no paranoia. Has been very popular as a day strain. Overall I«m very impressed, and would definitely grow this strain again.

In my opinion this strain is not very stable. Out of the 10 seeds I received, only 7 germinated. Out of those 7, 6 survived through vegetative. When flowered 5 of those 6 turned out to be male. The only one remaining showed pistils, however about 3 weeks in, male flowers developed as well. So out of 6 plants, 5 were male and one was a hermaphrodite. Very disappointed with this strain, I was expecting world class medicinal marijuana, and ended up with shoddy genetics. The hermaphrodite for the sake of having bud I grew out. The buds looked very much like Black Domina, however the potency was just not there. Knowing the plants parents, Black Domina and Jock Horror, I would say this plant has a lot of potential, but you may need more than 10 seeds to find that good mother.
