¶ Black Diamond
¶ Overview
Black Diamond is a pure indica cultivar created by crossing Blackberry with Diamond OG (itself an OG Kush derivative). This cross combines the sweet, berry-forward character of Blackberry genetics with the fuel-tinged potency of Diamond OG to produce a deeply sedating indica with a rich berry, earthy, and sweet terpene profile.

¶ Genetics & Lineage
Black Diamond is a two-way cross between two well-regarded indica genetics:
- Blackberry -- An indica cultivar known for its pronounced berry aroma and heavy body effects. Blackberry genetics carry the sweet, dark fruit character that has made berry-named strains popular in the indica market. The parent is valued for its ability to pass on both its distinctive berry terpene profile and its deeply relaxing physical effects.
- Diamond OG -- An OG Kush derivative, Diamond OG carries the fuel-forward, potent character of the OG family with a refined, crystalline quality reflected in its name. Diamond OG contributes potency, structural compactness, and a fuel-tinged undertone that adds complexity to the berry sweetness.
Parent lineage: Blackberry x Diamond OG (OG Kush x unknown)
This cross was designed to merge the sweet berry character of Blackberry with the OG-derived potency of Diamond OG. The result is a pure indica that delivers the sedating weight of classic indica genetics with a berry-sweet aromatic profile.
¶ Cannabinoid Profile
| Cannabinoid | Typical Range |
|---|---|
| THC (Total) | 17-22% |
| CBD | <1% (typically 0.1-0.4%) |
| CBG | 0.5-1.0% |
| CBN | <0.5% (increases with age) |
Black Diamond occupies the moderate THC range, making it accessible to a wide range of users. The moderate potency is paired with consistent, heavy sedation -- a hallmark of well-bred pure indica genetics.
¶ Terpene Profile
| Terpene | Approximate Share | Notes |
|---|---|---|
| Myrcene | 40-55% | Dominant terpene; earthy, herbal base; primary driver of the heavy sedation |
| Caryophyllene | 15-25% | Spicy, peppery notes; adds depth to the berry-sweet profile |
| Limonene | 10-18% | Citrus sweetness that enhances the berry character |
| Linalool | 3-8% | Floral, lavender notes that complement the berry aroma |
| Pinene | 2-5% | Subtle pine freshness from the OG Kush inheritance via Diamond OG |
The myrcene-caryophyllene foundation supports the heavy sedation, while limonene and linalool produce the signature berry sweetness that defines Black Diamond's aromatic identity.
¶ Effects & Experience
Black Diamond is widely reported to produce:
- Heavy sedation -- A deep, body-locking sensation that progresses from physical relaxation to pronounced drowsiness
- Full-body relaxation -- A thorough easing of muscle tension and physical discomfort from head to toe
- Mild euphoria -- A gentle mental calm that accompanies the physical sedation without excessive cerebral stimulation
- Stress relief -- Commonly reported reduction in mental tension as the heavy body effects settle in
Onset: Effects typically begin within minutes when smoked or vaporized; 30-90 minutes when consumed orally.
Duration: 2-3 hours for inhaled consumption; 4-8 hours for oral consumption.
Intensity: Moderate to strong. The moderate-to-high THC range and pure indica genetics produce effects that are best suited for evening use and may be overwhelming for inexperienced users at higher doses.
⚠️ Effects are self-reported and vary by individual, dose, tolerance, and consumption method. Not a prediction of any individual's experience. Due to the heavily sedating nature of this strain, avoid use before driving or operating machinery.
¶ Aroma & Flavor
Black Diamond presents a rich, berry-forward sensory profile:
- Smell: Pronounced berry and sweet aromas with earthy undertones. The Blackberry parent is immediately apparent in the dark fruit sweetness, while the Diamond OG genetics contribute an earthy depth and faint fuel undertone. The cured buds carry a rich, jam-like aroma that is sweet and inviting.
- Taste: Sweet berry flavors on inhalation, with earthy and slightly fuel-tinged notes on the exhale. The flavor is smooth and layered, with limonene providing faint citrus accents that enhance the berry character. The finish carries an earthy warmth that grounds the sweeter top notes.

- Pain management -- Deep body relaxation is commonly cited for relief from chronic pain, muscle spasms, and cramping
- Stress and anxiety reduction -- The calming body effect is reported to ease mental tension and promote deep relaxation
- Muscle relaxation -- Commonly used for relief from muscle tension, spasms, and physical stiffness
¶ Adverse Effects
Commonly reported adverse effects:
- Dry mouth
- Dry eyes
- Drowsiness (undesirable for daytime use)
- Dizziness at higher doses

¶ Growing Information
| Attribute | Details |
|---|---|
| Difficulty | Moderate -- requires standard environment control and attention to humidity management for dense, resinous buds |
| Flowering Time | 55-65 days (indoor) |
| Yield | 350-450 g/m² indoor; 400-500 g/plant outdoor |
| Plant Height | Short to medium -- compact pure indica structure with minimal stretch; very manageable size |
| Preferred Environment | Indoor or outdoor; prefers warm, dry conditions with consistent temperatures for optimal berry terpene expression |
| Resistance | Moderate resistance to mold and pests. The OG Kush-derived genetics from Diamond OG contribute some vigor. Dense, resinous buds require adequate air circulation to prevent bud rot in high-humidity environments. |
Black Diamond benefits from attentive growing practices typical of pure indica cultivars. The compact structure requires minimal training, though topping can improve light distribution to lower bud sites. The strain produces dark, resinous buds with heavy trichome coverage, making it visually striking and well-suited for both flower and extraction purposes. Nutrient management should be consistent, and humidity control is important during late flower. Outdoor harvest in the Northern Hemisphere typically falls in early to mid-October.
¶ Awards & Recognition
- OG Kush, the grandparent genetics via Diamond OG, remains one of the most influential and recognized lineages in cannabis history
- Blackberry genetics have maintained a steady presence in the indica market
- Black Diamond represents the convergence of two respected genetic families
