Where Space Rocks Comes From
Space Rocks is listed by both Leafly and AllBud as a cross of Space Queen and Rocky Mountain Blueberry, at about 60% indica and 40% sativa. Neither site names a breeder, and we found no breeder or seed bank claiming it. Grow Diaries lists the strain as well, without adding a breeder.
Its profile has grown through retail. Perfect Union, a California cannabis retailer, included it in a 2025 list of strains gaining momentum, featuring flower from the brand Mr. Zips and calling it deeply relaxing with a euphoric twist, best in the evening. The strain also appears on menus as flower and as unpressed hash. One strain-guide site cautions that the pedigree is not universally agreed and that batches vary, and some menus list a Sour Space Rocks, so confirm the lineage with the seller.
Space Rocks Effects: What It Feels Like
Leafly reviewers most often tag Space Rocks as creative, relaxed and energetic, and Leafly calls the effect mostly calming. AllBud describes a fairly quick onset with a bright, energetic mood and a dreamy, daydream-like headspace that makes focus slip. Grow Diaries reports an energetic, happy start that leads into physical relaxation.
The result is a strain that starts social and drifts toward the couch, which suits a late afternoon or early evening. Potency listings range from about 15% to 23%, with at least one retail batch testing higher, so start small.
Space Rocks Terpenes, Aroma and Flavor
Leafly lists blueberry, berry and pungent as the top flavors, and reviewers describe a sweet, earthy, kushy smell. AllBud describes sweet, sugary berries with bright citrus on the nose and a blueberry-citrus taste with subtle spice on the exhale.
Leafly names myrcene as the dominant terpene, which fits the ripe-berry, earthy base. No fuller terpene breakdown is published.
- Myrcene: earthy, musky and herbal, also found in mango and hops
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.
