Growing Black Jack (indoors and outdoors)
Black Jack is suitable for virtually any grower and is classified as relatively easy to grow. In addition, our Black Jack feminized cannabis seeds are suitable for indoor and outdoor cultivation and respond well to training methods such as SOG and SCROG.
Sufficient light and warmth are essential for good results. Due to this, a little extra help from a greenhouse can be a good idea if you live somewhere with cool, short summers.
Black Jack feminized cannabis seeds will grow into beautiful large roundish marijuana plants with a fine stature and bright green leaves during the growth phase. When the flowering stage arrives, you will see that the plant quickly transitions to developing buds that overflow with resin over time.
Flowering time
Black Jack has a relatively short flowering time that lasts a minimum of 8 and a maximum of 9 weeks (56 to 63 days). Grown outdoors in the Northern Hemisphere, your plant will be ready for harvest in October.
Plant height
Her 50% Indica to 50% Sativa ratio results in a cannabis plant with a very manageable height, making her perfect for indoor growing, as she will grow between 130 and 170 cm. Outdoors, however, the marijuana plant can grow quite large. If she were a human, she could easily play in the NBA, as she grows between 180 and 270 cm (!). Keep that in mind.
Black Jack yield
You can increase your chances of an optimal harvest by carefully applying nutrients during the vegetative phase and using the Sea of Green method. The maximum yield of Black Jack cannabis seeds, when grown indoors, is between 400-500 grams per square meter. Outdoor yields are usually better, and growers can harvest up to 500-700 grams per plant.
Effects of Black Jack
With its perfect ratio of 50% Sativa and 50% Indica genetics, the highs of Black Jack are extraordinary. The mix produces an ideal effect on the mind, body, mood, and appetite.
Black Jack is a potent weed and has a high THC content that can reach up to 21%. Its CBD content is usually around 0.6%.
The effect of the weed is anything but sleep-inducing, however she will make you feel relaxed. At the same time, you will experience euphoric effects, become talkative and get motivated. The high lasts quite long and is therefore ideal for daytime or evening. Moreover, this weed is often used medicinally to relieve stress, anxiety, and depressive feelings.
Side effects
Prepare yourself for serious "munchies"! It is advisable to stock up on snacks before taking a gamble with Black Jack (or hide all your snacks if you are trying to watch your calorie intake). Other side effects include dry mouth and eyes. We recommend novice cannabis users take it easy since the weed can be a bit overwhelming.
Smell and taste
Black Jack is always a pleasant smoke. You'll experience a sharp but pleasant pepper flavor with an aromatic flowery scent. Other features include a strong earthy flavor. The smoke is rich and so thick. It looks a bit like incense used in a church.
Origin
Black Jack seeds were created by crossing the Black Domina and Jack Herer. Over the years, Black Jack has won many awards, including the Argentine Outdoor Cata Cup of Cannabis Cultivators (CCCC) in 2012 and the Indoor Hydro Prize in Catalonia in 2014.

just got mines ill let you know on the updates thanks
Your blackjacks are doing great, 8 out of 10 sprouted. At this very moment it is the third week of growing and I can't say much about the final result but so far it seems really good. Do you have any tips on which nutriens will be best for the bjacks?
I must say, that I'm really happy with the customer service of weedseedsexpress. The packages did not arrive two times and still I got another package delivered. Many thanks!! I will write another review when the growing is finished.
Spicy weed man! Just did the first smoke session and this shit is great! Had no troubles growing, everything went great! Got the package very fast, great!
Really love the great customer care and genetics are very good. Your customer support is topnotch and really the best i have experienced so far in my 5 years of growing adventures so i'll be back soon for some more orders.
It has been worth all my money!
Its a great strain for growers with some experience. I can't say the strain was hard to grow, but it requires more skills. The customservice at weed seed express is perfect even is the speed of sending.
The cross of two heavy strains (Black Domina and Jack) makes this strain truely amazing. BlackJ produces produce very dense frosted buds wrapped in orange hairs. During flowering the smell is pretty pungent. A bit like a straight haze. Easy growing and a reasonable flowering time.
Blackjack has been my favorite strain for a long time now. I have been training myself with this strain for 1.5 years and am getting better. The seeds develop a plant with an above average height and large buds. Nice plant to experiment with.
Germination the seeds was as simple as ordering.
Thanks you WSE for your support team. However, for a second cultivation, this strain was a bit to hard for me i guess. This strain is probably suitable for more experienced growers, but i got some good yields. Next time i will choose a more easy to grow strain.
This BlackJack isn't a gamble. Perfect quality seeds from which 17 out of 20 have germinated now.
