THC percentage is a property of the product in your hand, not of the strain. It shifts with the batch, the grower, the harvest, and how the flower was cured and stored — the same strain can test several points apart from two different jars.

Professor High interprets the pattern

Settles deep into the couch with a satisfied sigh

Okay, so I just finished a session with Double Black, and the body sensation is absolutely remarkable. Within minutes, I felt this warm wave of muscular release starting at my shoulders and cascading down my spine like honey dripping down glass—slow, inevitable, thoroughly pleasant. The mental space is interesting: there's this gentle euphoria floating around my consciousness, not overwhelming, just... present, like a friendly observer noting how wonderfully my body has transformed into this perfectly relaxed organism.

The myrcene is definitely doing its thing here—I can feel that characteristic sedative pull that's simultaneously grounding and dreamy. My racing thoughts from earlier? Gone. Replaced by this calm contentment that makes everything seem less urgent, less demanding. The hunger kicked in around the 20-minute mark—suddenly every snack in my kitchen became fascinating. And now, about an hour in, I'm experiencing what I can only describe as therapeutic heaviness: my limbs feel weighted, supported, like gravity itself is giving me a hug. Perfect for studying the inside of my eyelids later tonight.

The helpful detail

A Pure Indica Powerhouse from Black Domina Genetics

Double Black is a potent 100% pure indica strain that emerged from the legendary cannabis breeding program at G13 Labs in the late 1990s. This strain represents a unique approach to cannabis genetics—created by crossing Black Domina 98 with itself to reinforce and stabilize the most desirable indica characteristics. The result is a deeply relaxing, sedating strain that exemplifies everything indica lovers seek: powerful body effects, profound relaxation, and a smooth, sweet flavor profile that lingers long after exhale. With THC levels ranging from 16-25%, Double Black delivers consistent potency that appeals to both medical patients seeking relief and recreational users looking for deep evening relaxation.

🧬 Genetic Heritage & Lineage

Double Black's lineage is both simple and sophisticated. By selfing Black Domina 98—a technique where a strain is crossed with itself—G13 Labs created a strain with remarkable genetic stability (approximately 90% stable) and predictable effects. Black Domina itself is a legendary indica created from a four-way cross of Northern Lights, Ortega, Hash Plant, and Afghani SA, making Double Black a concentrated expression of some of cannabis's most revered indica genetics. Developed in 1998 during the golden era of Dutch cannabis breeding, this strain carries forward the heavy-hitting indica tradition that defined that decade. The selfing technique ensured that Double Black would consistently express the most desired traits: dense bud structure, powerful sedation, and complex terpene profiles.

👃 Terpene Profile & Aromatics

Double Black's aroma profile is dominated by myrcene, the quintessential indica terpene known for its sedating, body-focused effects. This is supported by limonene (providing subtle citrus uplift), pinene (adding fresh, herbal notes), and caryophyllene (contributing spicy, peppery undertones). When you first open a container of Double Black, you'll notice an intoxicatingly sweet primary aroma that immediately captures attention. This sweetness is layered with earthy, spicy notes reminiscent of rich soil and exotic spices. Beneath the surface, you'll detect hints of berry, mint, and surprisingly, mango—creating an unexpectedly fruity dimension. Some phenotypes express woody and pine characteristics, while others lean toward a more hashish-like pungency. The overall aromatic experience is complex and evolving, revealing new layers as the buds warm in your hands.

👅 Flavor Experience

The flavor journey of Double Black mirrors its complex aroma but with distinct phases. On the inhale, you'll taste pronounced sweetness mixed with earthy undertones and a subtle berry note. Mid-palate, spicy and peppery flavors emerge, likely from the caryophyllene content, creating a warming sensation. Some users report distinct mango and peppermint notes that create an almost tropical-meets-herbal experience. The exhale leaves a lingering sweetness with pine and woody finish that coats the palate pleasantly. This flavor complexity makes Double Black a connoisseur strain despite its straightforward genetics—each consumption method reveals slightly different flavor nuances, with vaporization particularly effective at highlighting the fruit and mint notes.

🎯 Effects & Experience

As a pure indica, Double Black delivers effects that are predictably body-focused and deeply sedating. The onset is relatively quick—you'll begin feeling effects within 5-10 minutes of consumption. Initially, you may notice a subtle euphoric lift and sense of happiness that brightens mood without energizing. This quickly transitions into the strain's primary effect profile: profound relaxation that starts in the mind and cascades throughout the body. You'll feel muscle tension dissolve, stress evaporate, and a pleasant heaviness settle into your limbs. Many users report feeling simultaneously uplifted mentally while experiencing deep physical sedation—a classic indica dichotomy. The peak effects last 2-3 hours and include strong hunger stimulation (keep snacks nearby) and increasing drowsiness. As effects wind down, you'll likely feel ready for sleep, making this an ideal evening or nighttime strain. The intensity is moderate to strong depending on dosage, with experienced users reporting couch-lock at higher doses.

🎮 Use Cases & Activities

Double Black is purpose-built for evening and nighttime use. This isn't a strain for productivity or daytime activities—instead, it excels at helping you unwind after a long day. Ideal activities include:

  • Relaxation & Stress Relief: Perfect for decompressing and letting go of daily tensions
  • Sleep Support: Excellent for those struggling with insomnia or restless nights
  • Pain Management: Body-focused effects make it valuable for chronic pain relief
  • Evening Meditation: The mental calm pairs well with contemplative practices
  • Movie Nights: Settle in for extended entertainment sessions
  • Gentle Stretching: Light physical activity before the sedation fully sets in

Avoid this strain if you need to remain alert, productive, or socially engaged—Double Black is best enjoyed when you have nowhere to be and nothing demanding your attention.

💚 Medical & Therapeutic Potential

Double Black shows significant therapeutic potential, particularly for conditions requiring both mental calm and physical relief. The myrcene-dominant profile may help with chronic pain, muscle tension, and inflammation. The euphoric onset may provide relief from stress, anxiety, and depression symptoms, while the sedating progression makes it valuable for insomnia treatment. The pronounced hunger stimulation can benefit patients dealing with appetite loss from various conditions or treatments. As with all cannabis, start with low doses and consult healthcare providers, especially if managing serious medical conditions. The strain's predictable effects and stable genetics make it a reliable option for patients requiring consistent therapeutic results.

👁️ Visual Characteristics

Double Black buds are classically indica in structure—dense, compact, and heavy for their size. You'll see deep forest green base coloring often accented with subtle purple undertones, especially in cooler-grown phenotypes. The buds are typically covered in a thick layer of amber to milky-white trichomes, giving them a frosted, crystalline appearance. Orange to rust-colored pistils wind throughout, providing vivid contrast against the dark green backdrop. The resin production is generous, making buds sticky to the touch and leaving fingers coated after handling. The overall visual presentation screams quality indica genetics—tight, frosty, and potent-looking.

⚠️ Consumer Considerations

Best for: Experienced cannabis users seeking powerful evening relaxation; medical patients managing pain, insomnia, or stress; indica enthusiasts who appreciate classic sedating effects.

New users should approach cautiously: The sedating effects can be overwhelming for those with low tolerance. Start with small doses (one or two puffs) and wait at least 15 minutes before consuming more.

Common side effects include dry mouth, dry eyes, and occasional dizziness—standard indica experiences. Some users report slight paranoia at higher doses, so dose conservatively if anxiety-prone. Have water and eye drops ready, and plan to remain stationary once effects fully develop. This strain is widely available through Curaleaf dispensaries and G13 Labs seed retailers.
