Blue Knight

Blue Knight, aka “Blue Night” and “Blueberry Knight,” is an indica-dominant hybrid strain (cultivar). It is a cross between Blueberry and Kryptonite and has an aroma reminiscent of berries and vanilla. The taste is blueberry, earthy, and woody. Blue Knight has relaxing, sleepy effects, and many use it to relieve stress, pain, depression, and appetite loss.

Blue Knight’s THC levels have been measured from reasonably moderate to very high, with a potent average of around 22.5%. Blue Knight also contains a good amount of CBD, often measuring between 2.5% and 4%. However, some phenotypes of Blue Knight measure relatively low in CBD, so it’s a cannabinoid that’s not always found in this cultivar.

Blue Knight has sleepy, relaxing effects making it ideal for managing anxiety, insomnia, and chronic pain. Blue Knight has also been noted as an appetite stimulant, suggesting it may help manage chemotherapy-related appetite loss.

Although Blue Knight can be useful for managing chronic pain, some users have reported that it gives them headaches. Those intrigued by Blue Knight but prone to headaches may wish to try a version with less THC content and higher concentrations of CBD. Dry mouth and dry eyes are also common side effects of many cannabis varieties that can be reduced by relaxing and keeping well-hydrated.

Medical Applications

Blue Knight could be useful for managing the symptoms of many health conditions, including chronic pain, depression, multiple sclerosis, cancer and chemotherapy treatment, and insomnia.

Cancer (Non-Specific)

Blue Knight is known to stimulate appetite, which makes it very useful for managing the side effects of chemotherapy, one of which is appetite loss. THC stimulates the release of the hunger hormones leptin and ghrelin.

Organ Systems

  • Cancer
  • Other

The high levels of THC, combined with CBD, make Blue Knight an ideal way to reduce anxiety and prompt sleep. The presence of terpenes like myrcene and linalool can help induce sedation. Despite often being classified as being a more “uplifting” terpene, limonene may contribute to the sleepy effects of Blue Knight, primarily when used in high doses and combination with myrcene.

Organ Systems

  • Brain & Nervous System
  • Mental / Emotional



growing strains

Blue Knight is a relatively easy strain to grow and is an ideal choice for beginners. Blue Knight does well indoors and outdoors and may even slightly prefer the outdoors. The hybrid vigor of this plant makes it an excellent choice for those who want a more sedative indica. Blue Knight also grows relatively short, ideal for indoor or guerilla growers.


Blue Knight tends to be relatively short. Expect a height of around 4-5 feet, although it may grow taller in outdoor settings.

Humidity and Temperature

Like many varieties of cannabis, the ideal temperature is around 66 degrees Fahrenheit at nighttime and 78-82.5 degrees Fahrenheit in the daytime. The ideal relative air humidity is 60% during the vegetative period and 40% during the flowering period. Growing Blue Knight in cooler temperatures will likely lead to the production of anthocyanins in the plant, contributing to its blue and purple colors.


8-10 weeks (approximately 60-70 days).
