Genetic Analysis: The Charm of Blue

Blueberry genetics are renowned for introducing fruity aromatic profiles to a market dominated by earthy and pungent notes. In this Auto version, Bulk Seed Bank has retained the medium-large calyxes and structural robustness of the original strain. The addition of Canadian Ruderalis not only ensures autoflowering, but also gives the plant superior cold resistance, allowing it to thrive even in less mild climates.

The secret of color: Controlled temperature shock

The most sought-after characteristic of this strain is its ability to change color, a trait inherited directly from its “Blue” ancestors.

Technical advice from the Annibale Seedshop team: “To enhance the purple and blue pigments of Blueberry Berry Auto, try increasing the temperature difference between day and night during the final weeks of flowering. If you can keep nighttime temperatures cool (but above 8°C), you’ll stimulate the plant to produce anthocyanins, making the buds visually stunning and increasing the aesthetic value of the harvest”.

Indoor and Outdoor Cultivation

• Indoor: This is an excellent option for those looking to grow compact yet productive plants. With a yield of 475 g/m², it responds well to constant light cycles (18-20 hours) and doesn’t require excessively tall spaces.
• Outdoors: Thanks to its rapid growth cycle, outdoor growers can plan multiple plantings throughout the summer. It’s a discreet plant that rarely exceeds one meter in height, perfect for balconies or small gardens. It tolerates temperatures as low as 8°C, demonstrating a mettle worthy of its Canadian heritage.

Terpene Profile: A fruity and spicy dessert

The name Blueberry isn’t just marketing: the terpene profile is one of the most faithful to the original fruit you’ll find.

• Aroma: As soon as you open the jar, you’re hit with a sweet and fragrant aroma of ripe blueberries.
• Flavor: A complex mix on the palate. The sweetness of the berries is balanced by an undertone of Indian spices, adding an exotic and sophisticated note to every toke.

Blueberry Berry Auto is an “end of the day” strain. Its effect is markedly Indica:

FAQ

How much does it actually yield outdoors?

Outdoor yields vary greatly depending on the sunlight received. They range from 30g for plants in small pots or with limited exposure, up to 100g for plants grown in full sun and large pots.

Is it suitable for medicinal use?

Yes, it is highly valued for combating anxiety and insomnia thanks to its relaxing terpene profile and strong Indica dominance.

Can I grow it year-round?

Indoors, yes. Outdoors, it is possible as long as temperatures remain above 8°C, but for optimal results, it is always best to take advantage of the months with more hours of sunlight.
