Experiencing the cosmos is now possible thanks to Galactic Jack and its out-of-this-world high. This hybrid, known for its iconic Sativa effects, encourages a general sense of well-being and cheeriness. A cross between two of the finest there is, nothing short of exceptional is expected, and that is what it provides.

TGA Subcool developed Galactic Jack using two mostly Sativa strains. First is a hybrid they named after the famous marijuana activist Jack Herer. It is a universally loved hybrid that was released in the 90s and has since won multiple awards for potency and quality.

The female Jack Herer was then paired with a male Space Queen. Bred by Vic High, this strain is notoriously potent and can induce a trippy and speedy high.

As is expected when crossing two Sativa strains, its heritage is passed on to the offspring.

      Currently, there are four known phenotypes of Galactic Jack of which three are more similar to Jack Herer. Regardless of which, all are mostly Sativa and does not differ too much in growing traits. Like most others, growers can choose to plant it indoors or outdoors.

      It can be a little finicky though and will require experienced or expert hands. Besides the maintenance, the ambient temperature should also be closely monitored especially when grown outdoors as it does not tolerate abrupt changes well. Hence, beginners should find another strain to cultivate.

      Flowering Time


      The indoor flowering time for Galactic Jack is estimated to be between 8 to 10 weeks. This might seem like a longer amount of time than usual, but it is quite typical of Sativa dominant hybrids. Once harvest time comes, this strain produces about 8 to 10 ounces of buds.


      Galactic Jack thrives best when it is cultivated in warm temperatures. With the right amount of care, it can flower as early as the last week of September. During harvest time, growers can expect it to yield no less than 10 ounces of buds per plant.
