Where Blue Knight Comes From
Blue Knight is described on Leafly as an indica-dominant strain that stems from Blueberry and Kryptonite. Kryptonite is itself a clone-only strain with a rumored Mendocino Purps and Killer Queen background, and Leafly lists Blue Knight as one of Kryptonite’s offspring. No breeder is named for Blue Knight, and the strain goes by Blue Night and Blueberry Knight as well.
It is a rare name. Without a documented breeder, the lineage rests on Leafly’s description, so treat it as the common account rather than a verified record.
Blue Knight Effects: What It Feels Like
Readers describe a calming, relaxing high that centers on the body. Relaxed and sleepy are the top reported effects, with some tingling and, for some people, an increased appetite. It builds gradually and settles into a comfortable heaviness.
Because the listed THC is on the low side, it may suit people who want a mellow evening rather than a punch. Actual potency depends heavily on the grower and batch, so read the label.
Blue Knight Terpenes, Aroma and Flavor
The aroma is berry and vanilla, in line with the Blueberry side. Flavors are sweet blueberry up front, with earthy and woody tones on the exhale. Growers also describe colorful flowers mixing purple, blue and green.
Leafly lists pinene as the most abundant terpene, followed by limonene and terpinolene. Pinene is more often associated with a fresh pine scent, so the woody notes reviewers mention may come from it.
- Pinene: fresh pine, also found in pine needles and rosemary
- Limonene: bright citrus, also found in lemon and orange peel
- Terpinolene: fruity, piney and herbal, common in classic sativas
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.

Growing Blue Knight
- Difficulty: Moderate
- Flowering: Not documented
Leafly describes Blue Knight as resistant to mildew, which helps in damp climates. It suggests topping early for a bushier plant and removing lower branches, often called lollipopping, to encourage denser buds. Even with mildew resistance, good airflow matters in a wet Pacific Northwest autumn.
Home growing is legal for adults in Oregon (up to four plants per household) but only for registered medical patients in Washington; see the Oregon and Washington law guides. Many Oregon dispensaries sell clones and seeds; see where to buy clones in Eugene.
