Space Queen is a hybrid cannabis strain bred from Romulan and Cinderella 99, known for a fast, buzzy, trippy head high and a sweet fruit aroma of pear, apple and candy. It traces back to Pacific Northwest breeder Vic High and was later reworked by Subcool’s TGA Genetics. Leafly lists it around 21% THC, and its energy is closer to a sativa than its Romulan side suggests.

Where Space Queen Comes From
Space Queen pairs Romulan, a heavy indica line long associated with British Columbia and the Pacific Northwest, with Cinderella 99, the fruity, fast-finishing sativa. Leafly and SeedFinder both list that cross. Growers on SeedFinder credit the original work to Vic High, the breeder behind Pisces Genetics, who used C99 and Romulan as the starting point.
Subcool, founder of TGA Genetics, learned from Vic High and later revived the strain under his The Dank label as an F2, crossing his favorite phenotype with a Space Queen male. SeedFinder lists that version as roughly 70% sativa with a 50 to 60 day flower, and Subcool called it a TGA favorite. Other breeders, including Brothers Grimm and Lucky 13, have released their own Space Queen lines, so expect variation.
Space Queen became a cornerstone of TGA’s catalog. Leafly lists Space Candy and Jillybean among its offspring, and it is also a parent of Vortex.
Space Queen Effects: What It Feels Like
Space Queen comes on quickly. Leafly describes a buzzy, fast-onset head high that can feel intensely trippy and speedy, and its users name uplifted, euphoric and happy as the top effects. Subcool’s own description adds motivating and intense, with the honest warning that it can sometimes bring paranoia.
This is a daytime or early evening strain for people who like an energetic, heady high: music, art, a long walk or a lively hangout. The Romulan side adds some body comfort, but most people feel it mainly in the head. Because it can turn racy, newer consumers should start with a small amount.
Space Queen Terpenes, Aroma and Flavor
Space Queen is known for a fruit-forward nose. Leafly users list pear, apple and flowery notes, with Leafly’s description adding vanilla and cherry. Subcool describes candy, mango and dried fruit with a slightly sour, overripe fruit edge, and AllBud reviewers mention citrus, pineapple and tropical sweetness.
Leafly’s terpene data lists caryophyllene first, then humulene and limonene. Caryophyllene adds a light pepper note, humulene a woody, hoppy depth and limonene the citrus brightness that sits on top of the fruit.
- Beta-caryophyllene: peppery and spicy, also found in black pepper and cloves
- Humulene: woody and hoppy, also found in hops and basil
- Limonene: bright citrus, also found in lemon and orange peel
Terpene levels vary from grower to grower and batch to batch, so check the lab label on the package. Learn more in our guide to cannabis terpenes.
Side Effects and How to Use Space Queen
Leafly reviewers report dry mouth, dry eyes and dizziness most often. AllBud adds that headaches, paranoia and anxiety occur but are uncommon. Its speedy character is the main risk, so pace yourself.
If you are new to Space Queen, start with one small inhalation or 2.5 mg in an edible and wait before taking more; see our dosing guide.
Do People Use Space Queen for Medical Reasons?
On Leafly, people most often mention reaching for Space Queen for stress, low mood and anxiety, and AllBud users mention fatigue and headaches. These are user reports, not medical claims, and since its high can be speedy, people prone to anxiety should go slowly.
These are user reports, not clinical findings. For what research actually supports, see our cannabis health and research section, and talk to your doctor before using cannabis for a health condition.
Growing Space Queen
- Difficulty: Moderate
- Flowering: 50–60 days (Subcool’s The Dank version)
- Yield: Medium to high
- Height: Very tall
- Environment: Indoor or outdoor
Leafly notes that Space Queen stretches hard during the first three weeks of flowering and rewards growers with large, resinous buds; it suggests a soil pH of about 5.8 to 6.0. Subcool’s version is listed as very tall with a 50 to 60 day flower, so plan on a screen, trellis or stakes. Growers report both C99-leaning and Romulan-leaning phenotypes.
