Super Sour Diesel (often abbreviated as Super Sour D or SSD) is a potent, sativa-dominant cannabis strain that is renowned for its high energy, cerebral effects, and distinct diesel aroma. A cross between Super Silver Haze and Sour Diesel, Super Sour Diesel inherits the invigorating sativa effects of both parent strains, amplified by its high THC content that often exceeds 20–25%.
Genetic Lineage and Composition
- Parent Strains: Sour Diesel × Super Silver Haze
- Type: Sativa-dominant hybrid (90% Sativa / 10% Indica)
- THC Content: ~20–26%
- CBD Content: <1%
- CBG and Minor Cannabinoids: ~0.5–1% CBG, trace CBC and THCV
Genetic Profile Analysis
The high THC content and minimal CBD make Super Sour Diesel a strain with strong psychoactive effects, more suitable for experienced users or those seeking intense symptom relief. Its parentage combines Sour Diesel’s fast-acting cerebral high and Super Silver Haze’s euphoric and clear-headed buzz, resulting in a high-energy experience with minimal physical sedation.
Terpene Profile
The terpene content of Super Sour Diesel plays a critical role in its aroma, flavor, and therapeutic effects.
| Primary Terpenes | Approx. % | Effects |
|---|---|---|
| Myrcene | 0.4–0.8% | Sedation, muscle relaxant (moderate level) |
| Limonene | 0.6–1.2% | Mood elevation, stress relief |
| Caryophyllene | 0.3–0.7% | Anti-inflammatory, analgesic |
| Terpinolene | 0.3–0.6% | Uplifting, antioxidant, antimicrobial |
| Pinene | 0.2–0.5% | Alertness, bronchodilation |
The dominant citrus-fuel aroma is driven by limonene, terpinolene, and caryophyllene, while pinene and myrcene balance the strain’s uplifting qualities with a slight grounding effect.
Morphology and Cultivation
Growth Characteristics
Super Sour Diesel expresses classic sativa morphology:
- Tall, slender plants with long internodes
- Narrow fan leaves
- Vigorous vertical growth, especially during the flowering stretch
- Dense, trichome-rich colas with moderate leaf-to-calyx ratio
Scientific Traits:
- The elongated internodal spacing is due to expression of sativa-dominant photoperiod genes, which promote height over bushiness.
- Trichome production is abundant due to strong glandular trichome expression driven by both parental lineages (Sour Diesel and Super Silver Haze).
Environmental Requirements
A. Temperature and Humidity
- Veg Phase:
- Temp: 72–82°F (22–28°C)
- RH: 55–70%
- Flowering Phase:
- Temp: 68–78°F (20–25°C)
- RH: 40–50%
Scientific Rationale:
- Lower RH during flowering helps prevent botrytis cinerea (bud rot), especially important for Super Sour Diesel’s dense, sticky buds.
- Higher temps during vegetative stages promote enzymatic activity related to chlorophyll production and growth hormones like auxins and gibberellins.
B. Light Cycle
- Vegetative Phase: 18/6 (light/dark) for rapid canopy development
- Flowering Phase: 12/12 for photoperiod trigger
Scientific Insight:
- Super Sour Diesel is highly responsive to red/far-red light ratios during flower initiation. High phytochrome activation (via red spectrum) enhances flowering transition and bud development.
Nutrient Profile and Feeding Strategy
A. Macronutrients
- Nitrogen (N): High in veg, moderate in early flower
- Phosphorus (P): Increased during pre-flowering and flowering
- Potassium (K): High levels needed throughout flowering for resin and terpene synthesis
B. Micronutrients
- Magnesium (Mg): Essential for chlorophyll synthesis
- Calcium (Ca): Supports cell wall development
- Sulfur (S): Crucial for terpenoid biosynthesis (limonene, myrcene)
Feeding Schedule Summary:
| Phase | N-P-K Ratio | Notes |
|---|---|---|
| Vegetative | 3-1-2 | Promote foliage and structure |
| Pre-Flower | 2-2-2 | Transition nutrients for stretch |
| Flowering | 1-3-3 | Enhance bud density and oil production |
Scientific Note:
- Excess nitrogen in flowering may suppress terpene synthesis, particularly limonene and pinene, which are crucial for Super Sour Diesel’s signature profile.
Soil, Medium, and Microbial Life
A. Soil vs Hydro vs Coco
- Soil: Rich in microbial life, ideal for terpene expression. Organic super soil helps maximize flavor and resin production.
- Coco Coir: Offers control and faster growth, but requires precise feeding and pH management (5.8–6.2).
- Hydroponics (DWC or NFT): Delivers explosive growth and yield, but Super Sour Diesel may lose terpene complexity unless organic amendments or supplements are used.
B. Rhizosphere Biology
Using mycorrhizal fungi and beneficial bacteria (like Trichoderma spp. and Bacillus subtilis) supports:
- Nutrient uptake efficiency
- Root mass development
- Resistance to root pathogens
Training and Canopy Management
A. Training Techniques for Super Sour Diesel
- Topping – Essential for height control and lateral branching
- LST (Low-Stress Training) – Bending and tying stems to promote horizontal growth
- SCROG (Screen of Green) – Optimizes light penetration and yields in indoor environments
- Defoliation – Strategic removal of fan leaves to increase airflow and reduce humidity in dense canopy zones
Why this matters scientifically:
- LST and SCROG manipulate apical dominance and enhance auxin redistribution, promoting even canopy growth.
- Better light exposure to bud sites boosts photosynthetic efficiency and flower biomass.
Flowering Phase Specifics
Flowering Time: 10–11 weeks
Super Sour Diesel’s long flowering is due to sativa genetics, which have evolved in equatorial regions with longer photoperiods. As a result:
- Bud development is slower but denser over time
- Trichome maturation continues late into flowering (week 9+), impacting final potency
Ripening Monitoring:
- Trichomes should be mostly milky with ~10–15% amber for peak THC and terpene retention
- Terpene peak occurs 3–7 days before trichome oxidation begins—ideal for early harvest for maximum flavor
Terpene Preservation and Post-Harvest Techniques
A. Flushing
- Begin 10–14 days before harvest
- Use pH-balanced water (6.0–6.5) to remove nutrient salts
B. Drying
- Conditions: 60–65°F (15–18°C), 55–60% RH, 7–14 days
- Dark environment to protect cannabinoids and terpenes from UV degradation
C. Curing
- Cure in glass jars with daily burping for 2–3 weeks minimum
- Terpenes like terpinolene and limonene are volatile and degrade without proper humidity (ideal RH in jars: 58–62%)
Scientific Perspective:
- Improper curing can result in oxidation of THC into CBN and terpene evaporation, reducing potency and therapeutic value
- Curing enables enzymatic breakdown of chlorophyll, improving flavor and smoothness
Yield and Quality Optimization
| Method | Result |
|---|---|
| SCROG + LST | Up to 25% yield increase |
| Mycorrhizal use | Better nutrient uptake, root mass |
| Organic top-dress | Richer terpene profile |
| Late-stage defoliation | Airflow, trichome preservation |
With proper technique, Super Sour Diesel can yield:
- Indoor: 450–600g/m²
- Outdoor: 500–700g/plant in ideal climates
Pest and Disease Management
Common Risks:
- Spider mites
- Powdery mildew
- Aphids (especially outdoors)
Integrated Pest Management (IPM)
- Neem oil (veg only): Antifungal and insecticidal
- Predatory mites (e.g., Phytoseiulus persimilis): Biocontrol for spider mites
- Silica supplementation: Strengthens cell walls to resist pathogens
- Companion planting (outdoors): Marigolds, basil, and garlic repel aphids and whiteflies
Indoor vs Outdoor Cultivation Comparison
| Feature | Indoor | Outdoor |
|---|---|---|
| Control | Full (light, temp, RH) | Limited to climate and location |
| Yield Potential | High with training (SCROG) | Potentially higher but riskier |
| Aroma Management | Carbon filters required | More difficult to control |
| Terpene Quality | Often higher in soil-based outdoor | But can degrade with sun/heat exposure |
Super Sour Diesel performs exceptionally well indoors where conditions can be controlled, especially since its aroma is intense and can attract attention or pests outdoors, but the intense aroma requires carbon filtration for indoor setups.

Biochemical Mechanisms of Action
THC (Δ9-tetrahydrocannabinol)
- Binds: CB1 receptors (central nervous system)
- Effects:
- Psychoactivity
- Euphoria
- Increased dopamine
- Risks: Can induce anxiety or panic at high doses
CBD (Cannabidiol)
- Present in trace amounts in SSD, but plays a minor role
- Known for counteracting some THC effects (anxiolytic, antipsychotic)
Terpenes
- Limonene: Elevates mood by modulating serotonin (5-HT1A) and dopamine receptors
- Caryophyllene: Non-psychoactive, binds to CB2, reducing inflammation
- Pinene: Enhances memory, acts as a bronchodilator and stimulant
- Terpinolene: Mildly sedative yet mood-elevating, antioxidant
The entourage effect—the synergistic interaction between cannabinoids and terpenes—is key to Super Sour Diesel’s therapeutic effectiveness. For example, limonene and THC may synergize to increase antidepressant-like effects, while caryophyllene moderates inflammation without contributing to the high.
