Galactic Jack strain guide
Galactic Jack is a sativa-leaning hybrid most often described as a cross of Jack Herer and Space Queen. People know it for a sweet lemon and grapefruit smell and a focused, energetic feel. Who first bred it is less clear.
Where does Galactic Jack come from?
The cross most sources give is Jack Herer and Space Queen. Jack Herer is a famous haze-family sativa, and Space Queen is a fruity, upbeat hybrid of Romulan and Cinderella 99.
The breeder is not well documented. One strain database credits Heroes of the Farm Genetics, while another database lists Subcool as the source of the Jack Herer and Space Queen version. That database also notes a separate Galactic Jack from Sin City Seeds, made from different parents, so not every product with this name is the same plant.
What does Galactic Jack smell and taste like?
Galactic Jack smells like sweet lemon first, with grapefruit and a skunky, herbal edge underneath. Reviewers also mention pine, sage and a little pineapple.
Published terpene results put myrcene first, then pinene and limonene. Myrcene brings the herbal depth, pinene the pine and limonene the citrus. The flavour is sweet and lemony, with grapefruit and a little honey on the finish.
Galactic Jack effects: what people report
People most often describe Galactic Jack as focused and energetic, with an uplifted, carefree mood. It's usually talked about as a daytime strain, in line with its sativa-leaning parents.
These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth, dry eyes and headaches are the most common complaints, and a few people mention feeling dizzy or anxious.
How strong is Galactic Jack?
Galactic Jack is usually listed in the high teens to mid 20s. One strain database gives about 18% THC, while another database notes some tests above 26%. CBD is very low.
If you're new to it, start small and give it time before having more. The numbers on your label matter more than the strain name, and our guide to reading cannabis labels explains them.
Buying Galactic Jack in Canada
Since more than one breeder has used the name, check the producer and any lineage printed on the package.
You might find it as dried flower or pre-rolls. Look at the THC and CBD numbers and the packaging date, since fresher flower keeps more of the lemon smell.
Galactic Jack vs Space Queen
Space Queen is one of Galactic Jack's parents. Space Queen is known for a sweet, fruity smell, while Galactic Jack trades much of that for lemon, grapefruit and an herbal edge from Jack Herer. Both are described as upbeat, but Galactic Jack is more often called focused, and Space Queen more playful. If you like sweet tropical fruit, try Space Queen. If citrus and clear focus sound better, try Galactic Jack.
