Blueberry

Blueberry is one of the most iconic and best-loved varieties in the cannabis world. Created in the '70s by the famous breeder DJ Short, it has left its mark on history thanks to a unique genetic blend that includes Afghani, Thai and Purple Thai. In the '90s, Blueberry achieved worldwide fame and became a legend among growers and smokers.

Its mostly indica genetics (80% indica and 20% sativa) give it a sturdy, compact structure, ideal for growing indoors and outdoors alike. The plant stands out for its striking blue and purple colours, especially in the leaves and flowers towards the end of flowering and in cooler temperatures. Its buds are dense, resinous and a vibrant forest green with purple and red tones. Covered in a thick layer of trichomes, they glisten with a crystalline look that seems out of this world.

Blueberry is not just a visual treat: it is also very hardy and relatively easy to grow. Its leaves have broad petioles and a dark colour, and the internodal spacing is short, giving it a compact, strong structure. Outdoors it can take on a Christmas-tree shape, although some phenotypes show more columnar growth. Indoors, Blueberry is perfect for SOG set-ups if you select a mother plant that can supply the cuttings you need.

Flavour and effects

The aroma of Blueberry is simply unmistakable. It evokes the fragrance of fresh blueberries mixed with sweet, earthy notes. When smoked, the sweet berry flavour with a hint of pine surprises and delights, leaving a pleasant aftertaste. It is one of those varieties whose flavour, once tried, stays etched in your memory.

Blueberry's THC ranges from 20% to 24%, while its CBD is low, between 0.5% and 1%. This combination delivers a potent relaxing effect that starts with a light euphoria and turns into a deep sense of calm. Blueberry is perfect if you want to unwind and enjoy some calm, relaxing time. Despite its indica dominance, it does not cause heaviness or excessive drowsiness, so it suits any time of day.

Blueberry terpenes

Blueberry is rich in terpenes that not only build its aromatic profile but also shape its distinctive effect. The most notable include:

• Myrcene: with its herbal aroma, it contributes to the deep relaxation Blueberry offers.
• Caryophyllene: adds a spicy touch that rounds off the flavour.
• Pinene: gives a refreshing pine aroma and is associated with a clear, focused effect.
• Humulene: with its earthy aroma, it completes the relaxing character of this variety.
• Limonene: adds a citrus touch and is associated with a cheerful effect, making Blueberry a lively, invigorating experience.
• Eucalyptol: offers a fresh minty aroma that adds a refreshing dimension to the Blueberry experience.

This rich blend of terpenes not only enhances the sensory experience but also deepens the relaxing effect of this incredible variety. Blueberry stands out as much for its flavour and aroma as for the experience it offers those who choose it.

Yield and flowering time

Blueberry stands out for its generous yield and relatively short flowering time, making it an attractive option for novice and experienced growers alike.

Indoors, Blueberry can yield up to 500 grams per square metre, an abundant harvest in a controlled space. Indoor flowering takes 7–8 weeks, so you can enjoy a rich, resinous harvest without a long wait. It is ideal for the SOG (Sea of Green) method, which makes the most of the space and ensures even bud development.

Outdoors, Blueberry plants can produce around 550 grams per plant in optimal conditions, with enough sun and a suitable climate. In the northern hemisphere, we recommend sowing Blueberry cannabis seeds in April, with the harvest expected between late September and mid-October. This schedule ensures the plants get as much sunlight as possible during their cycle, maximising both the quality and the quantity of the harvest.

How to grow Blueberry

At Bulk Genetics, we believe growing Blueberry can be a rewarding experience for novice and experienced growers alike. Its growing difficulty is moderate: with a little care and attention, anyone can achieve a good harvest.

For the best results, we recommend growing Blueberry in a temperate climate, with daytime temperatures between 20 °C and 27 °C and slightly cooler nights. It adapts well to both indoor and outdoor growing, but it is essential to keep it in a well-ventilated space with controlled humidity.

Blueberry is a sturdy plant with moderate resistance to pests and diseases. Even so, it pays to keep an eye out for potential problems and keep your plants clean and healthy. Indoors, we suggest the ScrOG (Screen of Green) method to make the most of the space and ensure even growth. Outdoors, choosing a spot with plenty of sun and protecting the plants from bad weather is key to a bumper harvest.
