Jack Black Auto

Jack Black Auto is a gem born from a masterful cross between the legendary Jack Herer, the powerful Black Domina and a fast Ruderalis. The result is an autoflowering strain that stands out for its sativa dominance, with vigorous growth and an impressive yield. With its short life cycle and heavy production, Jack Black Auto is a favourite with novice and experienced growers alike.

Jack Black Auto has a sturdy, compact structure, with medium internodes and long branches growing out of a thick main stem. During flowering, the branches fill with dense buds covered in a thick layer of resinous trichomes, giving it an almost celestial look, as if dusted with stardust. The deep green leaves are set off by pistils ranging from orange to purple, making for an impressive sight in any garden.

Flavour and effects

The aroma of Jack Black Auto is a sensory journey that combines sweet and incense notes, recalling the serene, mysterious atmosphere of an ancient cathedral so typical of Haze genetics. Its flavour is just as fascinating, blending sweetness with a spicy touch that leaves a long, pleasant aftertaste.

Jack Black Auto delivers a euphoric, stimulating effect that is ideal for moments of creativity and focus. This cerebral high comes with a subtle but noticeable body relaxation, striking a perfect balance between energy and calm. With THC levels of 17% to 19%, this strain offers a potent experience without being overwhelming. The CBD, though low (around 1.1%), rounds off the effect of the THC with a mellow sense of well-being.

Yield and flowering time

Jack Black Auto is a champion when it comes to yield, both indoors and outdoors. Thanks to its well-balanced genetics and autoflowering nature, it gives you quick, generous harvests.

Indoors, Jack Black Auto goes from germination to harvest in 8 to 10 weeks. Under optimal growing conditions, yields range from 400 to 550 grams per square metre. Its compact size and fast flowering make it perfect for small spaces, letting you maximise your yield without sacrificing quality.

If you prefer growing outdoors, Jack Black Auto also gives impressive results. Sown in spring, from April onwards in the northern hemisphere, it is ready to harvest around 8 to 10 weeks later, and you can fit in more than one run before autumn. Outdoors you can expect 100 to 150 grams per plant, depending on the climate and the amount of sunlight it gets. The plant grows up to 110 cm tall, making it manageable and discreet in a garden or on a terrace.

How to grow Jack Black Auto

At Bulk Genetics, we believe growing Jack Black Auto is a rewarding, accessible experience for growers of every level. It is moderately easy to grow, which means beginners and seasoned growers alike can get good results with a little attention and care.

To bring out the full potential of Jack Black Auto, give it the right climate and growing conditions. It thrives in warm, sunny environments, but also adapts well to indoor grows, where conditions are easier to control. Keeping daytime temperatures between 20 and 26 °C, with slightly cooler nights, will help your plants grow healthy and productive.

One of the big advantages of Jack Black Auto is its resistance to pests and diseases. While it is important to keep the grow area clean and watch out for potential problems, this strain has proven quite tolerant of the usual challenges of growing cannabis.

To maximise the yield and quality of your buds, we recommend using a quality substrate and keeping the grow area well ventilated. You can also use low-stress training (LST) to spread the light evenly across the whole plant and boost your yield.
