Blueberry, also known as “Berry Blue,” is an indica-dominant strain comprised of 80% indica and 20% sativa created by breeder DJ Short in the 1970s. He began crossbreeding landrace strains that developed in the wild without human interference.  He crossed an Afghani indica with a Highland Thai sativa and Purple Thai sativa, yielding the hybrid strain aptly named for its fresh blueberry fragrance and taste and bright blue hues in its leaves and buds.

It’s also a very potent strain with a THC content of between 16% and 23.5% and a CBD level of around 0.26%. Blueberry is noted for its ability to combat anxiety and stress, facilitate calmness and ease restlessness. Blueberry is an ideal strain for managing chronic pain and insomnia, and some have claimed that Blueberry is arousing as well.

It is one of the most popular strains on the market, and in 2000 Blueberry won the High Times Cannabis Cup in the Best Indica and Best Overall strain categories. It received third place in the Overall category in 2001.

growing strains

Blueberry plants are suitable for beginner growers as they are straightforward to grow and require a shorter flowering time than other strains. Blueberry flourishes outdoors but requires regular pruning to prevent powdery mildew from dominating it.

During the early seedling stage (two to three weeks), Blueberry requires high nitrogen levels. Soil should be prepared with high-grade fertilizer in the greenhouse before the plant is shifted outdoors.

There are a few pruning techniques used to increase yield. “Topping” (cutting the plant’s main stalk) sculpts it into a bush shape. If it grows into this structure, it will put more resources into developing buds and take up less space. Pruning also increases airflow to prevent powdery mildew infection.

Blueberry cannabis has a reputation for producing high yields compared to other strains, attributed to its aforementioned bushy shape. Indoors it can provide 18 ounces of bud per square meter. However, outdoors, you can expect a yield of up to 25 ounces per plant. In addition to nitrogen, silica and iron are minor nutrients that could also help boost the health of your Blueberry plant.


Blueberry needs space to flourish when grown indoors – this fruity strain can reach a height between 20-30 inches. Outdoors it is expected to grow to over 3 feet.

Humidity and Temperature

Blueberry requires a milder climate than other cannabis strains. It thrives at temperatures between 65 and 80 degrees Fahrenheit (18.3 to 26.7 degrees Celsius), though it can handle colder nighttime temperatures without a significant effect on yield.


Blueberry begins to flower in about seven to nine weeks. When grown under ideal conditions, buds can be expected in less than two months.
