¶ Blueberry
¶ Overview
Blueberry is an indica-dominant cultivar created by legendary breeder DJ Short in the 1970s. By crossing Purple Thai, Thai, and Afghani genetics, DJ Short produced a strain with an unmistakable fresh blueberry aroma and flavor that remains unique in cannabis. Blueberry won Best Indica at the High Times Cannabis Cup in 2000 and has since become one of the most influential fruity-flavored strains in cannabis breeding. Its genetics form the foundation of numerous modern berry-flavored cultivars, including Blue Dream, and the "Blue" family of strains is among the most recognizable brand names in cannabis.

|---|---|
| Type | Indica |
| THC % | 16-24% |
| CBD % | <1% |
| Dominant Terpenes | Myrcene, Caryophyllene |
| Flowering Time | 45-55 days |
| Yield | Moderate (350-450 g/m² indoor) |
| Growing Difficulty | Moderate |
¶ Genetics & Lineage
Blueberry is a three-way cross developed by DJ Short over years of selective breeding:
- Purple Thai -- A sativa-dominant strain contributing purple coloration and fruity characteristics
- Thai -- A pure sativa landrace from Thailand, adding complexity and vigor
- Afghani -- A pure indica landrace from Afghanistan, bringing the indica structure, resin production, and short flowering time
Parent lineage: Purple Thai x Thai x Afghani
DJ Short worked with these genetics throughout the 1970s, gradually stabilizing the blueberry flavor phenotype. The resulting strain was eventually distributed through Dutch seed banks and gained worldwide recognition. Blueberry's most famous offspring is Blue Dream (Blueberry x Haze), which has become one of the most widely cultivated and sold strains in the world.
¶ Cannabinoid Profile
| Cannabinoid | Typical Range |
|---|---|
| THC (Total) | 16-24% |
| CBD | <1% (typically 0.1-0.3%) |
| CBG | 0.5-1.0% |
| CBN | <0.5% (increases with age) |
The broad THC range reflects variability between different Blueberry phenotype selections. DJ Short's original work produced multiple phenotypes, some leaning more toward the indica side (heavier, more sedating) and others retaining more sativa character (more uplifting and cerebral).
¶ Terpene Profile
| Terpene | Approximate Share | Notes |
|---|---|---|
| Myrcene | 30-50% | Primary terpene; earthy, herbal base |
| Caryophyllene | 15-25% | Spicy, peppery depth that complements the fruit notes |
| Pinene | 5-10% | Subtle pine freshness |
| Linalool | 3-8% | Floral notes enhancing the berry character |
| Limonene | 2-5% | Minor citrus accents |
While the terpene profile is myrcene-dominant (typical of indica strains), it is the specific combination of terpenes -- particularly the interaction between myrcene, caryophyllene, and minor fruit-derived aromatic compounds -- that produces Blueberry's distinctive flavor.
¶ Effects & Experience
Blueberry is widely reported to produce:
- Relaxation -- A comfortable, full-body calm that eases physical tension
- Happiness and euphoria -- A pleasant mood lift with gentle cerebral contentment
- Mild sedation -- Progressively calming, though generally less sedating than heavy kush varieties
- Sensory enhancement -- Some users report heightened appreciation for taste, music, and other sensory experiences
Onset: Effects begin within minutes when smoked or vaporized; 30-90 minutes when consumed orally.
Duration: 2-3 hours for inhaled consumption; 4-6 hours for oral consumption.
Intensity: Moderate. Blueberry's effects are enjoyable and accessible, making it suitable for a range of experience levels.
⚠️ Effects are self-reported and vary by individual, dose, tolerance, and consumption method. Not a prediction of any individual's experience.
¶ Aroma & Flavor
Blueberry is famous for its distinctive sensory profile:
- Smell: Unmistakable fresh blueberry sweetness, with earthy and floral undertones. The aroma is sweet and fruity without being artificially candy-like -- it closely resembles actual ripe blueberries.
- Taste: Fresh blueberry flavor on both inhale and exhale, with subtle earthy and slightly spicy undertones. The smooth, sweet flavor is one of the most recognizable in cannabis and is the primary reason for the strain's enduring popularity.
¶ Medical Usesdanger
Not Medical Advice -- The following lists commonly reported therapeutic applications. This does not constitute medical advice. Consult a healthcare professional before using cannabis therapeutically.
Commonly reported uses include:
- Stress and anxiety relief -- The calming mood-lifting effect is commonly cited for stress reduction
- Pain management -- Gentle body relaxation is reported to ease mild to moderate pain
- Mood elevation -- The euphoric quality is frequently used for depression and low mood
- Sleep support -- The progressively calming effect can support sleep onset, though it is less sedating than heavy indica kushes
¶ Adverse Effects
Commonly reported adverse effects:
- Dry mouth
- Dry eyes
- Mild dizziness at higher doses
- Drowsiness (may interfere with daytime productivity)
- Anxiety possible at high doses, though less commonly reported than with high-THC sativa strains
¶ Growing Information
| Attribute | Details |
|---|---|
| Difficulty | Moderate -- requires some experience to maximize flavor and yield |
| Flowering Time | 45-55 days (indoor) -- notably fast for a strain with sativa heritage |
| Yield | 350-450 g/m² indoor; 450-550 g/plant outdoor |
| Plant Height | Short to medium -- compact indica structure with some sativa stretch |
| Preferred Environment | Indoor or outdoor; performs well in both. Cooler temperatures during flowering can enhance blue/purple coloration in some phenotypes. |
| Resistance | Moderate resistance to mold and pests. The dense, resinous buds require adequate airflow to prevent bud rot. Generally healthy and vigorous. |
Blueberry is a moderately easy strain to grow. Its relatively fast flowering time (45-55 days) is a notable advantage inherited from its Afghani parentage. The strain responds well to SOG (sea of green) and SCROG (screen of green) methods. Blue and purple coloration may appear in the foliage and buds when nighttime temperatures drop during flowering, though this is phenotype-dependent. Outdoor harvest in the Northern Hemisphere typically falls in late September.
¶ Awards & Recognition
