Pack size

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 favorite with new 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 heavenly 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 grow.

Flavor 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 old cathedral so typical of Haze genetics. Its flavor 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's ideal for creative, focused moments. This head 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 out the effect of the THC with a mellow sense of well-being.

Yield and flowering time

Jack Black Auto is a champ 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 ideal growing conditions, yields range from 1.3 to 1.8 oz per square foot. Its compact size and fast flowering make it perfect for small spaces like a grow tent or closet grow, letting you maximize your yield without sacrificing quality.

If you prefer growing outdoors, Jack Black Auto also gives impressive results. Planted out after the last frost (April to June, depending on your area), it's ready to harvest around 8 to 10 weeks later, and you can fit in more than one run before fall. Outdoors you can expect 3.5 to 5 oz per plant, depending on the climate and how much sun it gets. The plant grows up to about 43 inches tall, making it manageable and discreet in a backyard or on a patio.

How to grow Jack Black Auto

At Bulk Genetics, we think growing Jack Black Auto is a rewarding, accessible experience for growers of every level. It's 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 68 and 79 °F, 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's 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 maximize the yield and quality of your buds, we recommend using a quality growing medium 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.
