Jack 47 Auto: Expect extreme potency from this treasured autoflower

Sweet Seeds developed Jack 47 Auto, which is one of the most potent autoflowers out there; the THC-levels are off the charts. This sativa-dominant strain makes the consumer fly, and the aromas are very appetizing. It’s a great strain, to say the least, and cannabis connoisseurs have embraced this cultivar with love. Let’s check out what Jack 47 Auto is all about.


Sweet Seeds brought out their very special Jack Herer pheno, and introduced it to their elite AK 47 Auto. The Jack Herer strain is, of course, named after the legend himself. The strains got along nicely, and produced a powerful hybrid. This ganja offspring, Jack 47 Auto, became their pride and joy. One can expect 75% sativa, 15% indica, and 10% ruderalis genetics, making this cultivar an uplifting one. Perfect for arts & crafts time, or for activities that require fervor and creative thinking. The limits of creativity are expanded. As mentioned, the THC-levels are quite high, so merely trace amounts are required for the desired effects.


This cultivar reaches classic autoflowering heights. Indoors, growers can see Jack 47 Auto reach around 50-120cm. Outdoors, it becomes comparatively short. 450-600g/m² of potent nugs can be expected from indoor operations. Outdoor growers will receive around 50-200g/plant, which is abundant for an autoflowering strain. The lifespan of this magnificence lasts for 9-10 weeks, from seed to harvest. When growing autoflowering strains outdoors, one needs to sow the seeds before the warmest 2 months of the year arrive. This will allow the plant to receive the maximum amount of energy from the sun.
