Ace of Spades Seeds: TGA Subcool's Award-Winning Indica Hybrid

History and Genetic Lineage

Ace of Spades was created in the late 2000s by Subcool, the founder of TGA Genetics, working out of his Oregon-based breeding operation. The strain was officially released around 2010 and quickly became one of the most discussed entries in TGA's catalogue.

The genetic foundation crosses Black Cherry Soda — itself a deep-purple Cinderella 99 derivative — with Jack the Ripper, Subcool's signature high-THC sativa-leaning male. Subcool selected this combination specifically to fuse the cherry-soda terpene profile of Black Cherry Soda with Jack the Ripper's resin production and structural vigour.

Ace of Spades earned a placement on High Times Top 10 Strains during its peak commercial years and was named the magazine's Strain of the Month, alongside multiple wins in regional cup events. The strain became a flagship product for TGA Genetics until the company's operations wound down following Subcool's passing in 2020.

Authentic original-line Ace of Spades seeds became increasingly scarce after TGA ceased operations, but several boutique preservationist breeders have released verified S1 reproductions and backcrosses that maintain the original phenotype with reasonable accuracy.

Subcool's Breeding Philosophy

Subcool worked with a clearly defined philosophy that prioritized terpene complexity over raw THC numbers and consistently selected for stable, recognizable flavors that could be reliably reproduced across multiple seed runs. He famously favored hand-pollination methods and small batch sizes that allowed careful phenotype tracking.

His approach to stabilizing genetics involved running multiple generations of selection from large populations, typically 50 to 100 seeds per generation, which gave him the statistical depth to lock in desired traits. His cultivation books remain widely referenced even after his death.

Cannabinoid and Terpene Profile

Lab-tested Ace of Spades flower averages 22 to 25 percent THC across legal-market samples, which placed it among the highest-testing indica-leaning hybrids during its commercial peak. Top phenotypes occasionally cross 27 percent under optimal indoor conditions, while outdoor crops typically test 1 to 2 percent lower than indoor equivalents.

CBD remains negligible at under 0.3 percent, which is consistent with most TGA Genetics releases of the era. Minor cannabinoid content includes CBG at 0.4 to 0.7 percent and CBN that climbs above 0.5 percent in flower aged beyond 4 months, contributing to the strain's reputation for long-lasting body effects.

The terpene picture is dominated by myrcene at 0.6 to 0.9 percent, providing the earthy mango-fruit base note. Caryophyllene appears as the second terpene at 0.3 to 0.4 percent, contributing peppery warmth and documented anti-inflammatory properties that some patients value, while limonene rounds out the top three at roughly 0.2 percent with citrus uplift.

Variability between cuts is significant — original TGA seed runs produced more terpene diversity than later S1 reproductions, with original-line Ace of Spades expressing slightly sharper cherry top notes.

Appearance, Aroma and Flavor

Ace of Spades buds are visually unmistakable, ranging from dark green with violet veins to nearly pitch-black purple in cool finishes. Calyxes stack tightly into chunky, dense flowers with a structure denser than most sativas of the same THC range, giving the buds a satisfying weight relative to volume.

The leaves often turn deep maroon or near-black in late flower if night temperatures are managed correctly, an effect inherited from the Black Cherry Soda parent. Trichome coverage is heavy and consistent across the plant, with bracts and sugar leaves both glistening under direct light.

The dominant aroma combines ripe black cherry, sweet berry, and a damp earth base reminiscent of forest soil. This fruit-and-earth pairing is the strain's signature and distinguishes it sharply from the candy-sweet dessert hybrids that dominate the modern market. Secondary peppery notes contribute by Jack the Ripper add complexity to the otherwise sweet profile.

On inhalation, the smoke is smooth and full-bodied, expanding gently in the lungs without the harshness of some high-THC modern hybrids. The exhale carries a distinct cherry-and-pepper finish, and the aftertaste lingers as a sweet-earth combination that reviewers consistently describe as memorable.

Visual Markers of Quality Buds

• Deep purple coloration. Genuine Ace of Spades buds finished in cool conditions display saturated dark violet to near-black flowers, with leaves matching the same colour palette. Pale or fully green buds typically signal incorrect finishing temperatures rather than poor genetics.
• Bud density and weight-to-volume ratio. Quality Ace of Spades produces rock-hard buds that feel surprisingly heavy for their size. Spongy or airy flowers indicate insufficient lighting, nutrient issues, or low-quality phenotype expression that fell short of the strain's potential.
• Heavy trichome coverage. Premium Ace of Spades flowers appear sugar-coated under bright light, with trichome density extending across calyxes, sugar leaves, and even fan leaf edges. Sparse trichome coverage suggests early harvest or stressed plants that did not fully develop.
• Vibrant orange pistil contrast. Burnt-orange pistils weaving through deep purple calyxes is the strain's most photogenic visual signature. Brown or wilted pistils point to over-aged buds or poor curing, while sparse pistils indicate immature flowers.
• Absence of brown leaf edges or moldy spots. Quality flowers show clean leaves without burn marks, brown edges, or grey-fuzzy mold patches. Any of these defects indicates either nutrient imbalance during growth or poor curing conditions after harvest.
• Strong aroma when squeezed. Pinching a quality bud between fingers should release a powerful cherry-berry-earth aroma that sticks to the skin. Weak aroma signals rushed drying or excessive curing time.

Growing Ace of Spades — Cultivation Insights

Ace of Spades sits at intermediate cultivation difficulty. The plant is relatively forgiving in pest resistance and structural strength, but achieving the signature deep purple expression and full terpene profile requires attention to environmental detail that exceeds beginner-level skill.

Indoor cultivation produces the most consistent results because cool night temperatures and humidity levels can be reliably engineered. Most cultivators run an 18/6 light cycle in vegetation and switch to 12/12 once plants reach 50 to 60 percent of target final height. The plant typically finishes at 90 to 130 centimetres indoors with moderate stretch.

Vegetative temperatures of 23 to 26 degrees Celsius and 60 to 65 percent humidity work well, with flowering shifting to 20 to 23 degrees daytime and as low as 15 to 17 degrees Celsius at night during the final 3 weeks to maximize purple expression. Humidity should drop from 55 percent in early flower to 38 to 42 percent in the final fortnight to prevent botrytis in dense colas.

The strain tolerates moderate-to-heavy feeding, with EC values of 1.5 to 1.9 in mid-flower being typical. Ace of Spades is moderately resistant to powdery mildew and spider mites, but the dense bud structure makes it susceptible to bud rot if humidity is not actively controlled in late bloom.

Indoor Setup Recommendations

1. Lighting power and spectrum. Use 600 to 1000 watts of HPS or 400 to 600 watts of high-quality LED per square metre. Full-spectrum LED with red-bias finishing modes accentuates resin production and supports the late-flower colour transition.
2. Temperature differential for purple expression. Hold daytime flowering temperatures at 22 degrees Celsius and drop nighttime values 8 to 10 degrees lower from week 6 onward. This temperature delta is the single most powerful trigger for the strain's signature anthocyanin development.
3. Humidity reduction schedule. Begin flower at 55 percent relative humidity and step down by 4 to 5 percent per week, finishing at 38 to 42 percent during the final fortnight. This schedule prevents grey mold without stressing trichome production or terpene expression.
4. Pot size and substrate. Use 15 to 25 litre fabric pots with a peat-coco-perlite blend or organic living soil. Larger root systems support the heavy late-flower demands of dense purple buds, and fabric pots ensure aerobic root health throughout the cycle.
5. Feeding rhythm by stage. Build moderate nitrogen during weeks 1 to 4 of vegetation, then transition to phosphorus-and-potassium-heavy bloom feed by week 3 of flower. Flush with plain pH-balanced water for the final 10 to 14 days to ensure clean terpene expression.
6. Canopy ventilation. Run oscillating fans at multiple canopy heights and an active extraction fan sized to exchange tent volume every minute. Stale air pockets within dense Ace of Spades canopies are the single most common trigger for botrytis outbreaks in late flower.

Outdoor Cultivation Considerations

• Mediterranean climate suitability. Ace of Spades thrives in Mediterranean-type climates with daytime highs of 24 to 28 degrees Celsius, low autumn humidity, and cool October nights that trigger purple expression naturally. Northern European latitudes can also work with greenhouse protection.
• Planting and harvest timing. Transplant outdoor seedlings after the last spring frost, typically in late April or early May in the Northern Hemisphere. Expect harvest between October 5 and October 25 depending on latitude, with cooler regions finishing slightly earlier than warmer ones.
• Late-flower rain protection. Dense Ace of Spades buds are vulnerable to rain-induced bud rot during the final 3 weeks of flower. Tarp coverage during rain events, removable greenhouse protection, or strategic positioning under building eaves can prevent the strain's most common outdoor failure mode.
• Soil amendment and feeding. Build a living-soil bed amended with worm castings, fish bone meal, kelp meal, and compost at planting. Top-dress monthly with compost and rock dust through vegetation, then reduce feeding inputs during the final 3 weeks to allow clean finishing.
• Concealment with purple colors. The strain's deep purple foliage stands out dramatically in autumn landscapes, which can complicate discreet outdoor cultivation. Pair plants with native deciduous companions whose autumn colors blend visually, and avoid planting against bright green backgrounds that emphasize contrast.

Flowering Time, Yield and Harvest

Indoor flowering runs 8 to 9 weeks from the 12/12 flip, with most phenotypes finishing close to day 60 and slower indica-leaning cuts pushing toward day 65. Outdoor harvest in the Northern Hemisphere typically falls in mid to late October, with Mediterranean climates producing the most reliable finishes.

Indoor yields range from 400 to 550 grams per square metre under quality lighting, with experienced SCROG growers occasionally reaching 600 grams per square metre. Outdoor plants in optimal soil produce 500 to 800 grams each, while exceptional specimens with extended vegetation can cross 1 kilogram in greenhouse conditions.

Visual harvest readiness shows when most trichome heads have shifted from clear to milky white with 10 to 20 percent amber, paired with 70 to 80 percent of pistils having darkened and curled inward. Cutting earlier preserves more cerebral lift, while cutting later emphasizes the heavy body sedation that defines mature Ace of Spades.

Slow drying at 18 degrees Celsius and 55 percent humidity for 12 to 14 days, followed by a 4 to 6 week jar cure with daily burping in week one, locks in the strain's signature cherry-berry-earth profile and preserves the deep purple bag appeal.

Effects, Medical Use and Consumer Experience

The first 5 to 10 minutes after consumption deliver a fast-rising cerebral hit that drops users immediately into a noticeably altered state. Ace of Spades is not subtle in its onset, which is why most experienced reviewers recommend new users start with the smallest possible dose and wait at least 20 minutes before considering more.

The peak phase, lasting 90 to 120 minutes, layers heavy physical relaxation onto the initial cerebral lift. Users report melted-into-the-couch sensations, slowed time perception, and significant appetite stimulation. Conversation remains possible, but motor coordination drops noticeably during this window.

The final phase pulls firmly toward sleep, with most consumers finding it difficult to remain awake past the 2-hour mark. Total effect duration runs 3 to 4 hours including the comedown tail, which makes Ace of Spades strictly an evening cultivar best paired with low-stakes activities and an early bedtime.

Reported side effects include cottonmouth, dry eyes, mild dizziness in higher doses, and occasional anxiety or paranoia in users who exceed their tolerance. The strain has gathered consistently strong reviews on Leafly, AllBud, and other rating platforms, averaging 4.4 to 4.7 stars during its commercial peak.

Medical Conditions It May Help With

1. Chronic insomnia and sleep disorders. The strain's heavy sedative tail and elevated CBN content combine to produce reliable drowsiness within 60 to 90 minutes of consumption. Patients commonly dose 30 to 45 minutes before bedtime via vaporizer at 0.05 to 0.1 grams for sleep-onset support.
2. Chronic pain conditions. Ace of Spades is widely used for arthritis, fibromyalgia, and post-injury chronic pain because its myrcene-and-caryophyllene combination offers both muscle relaxation and anti-inflammatory effect. Doses of 0.1 to 0.2 grams typically produce 3 to 4 hours of relief.
3. Anxiety and panic disorders. The strain calms anxious mental loops effectively at moderate doses, though excessive dosing can paradoxically increase anxiety in sensitive users. Microdoses of 0.05 grams via vaporizer offer the cleanest anxiety relief without overwhelming sedation.
4. Depressive states. Ace of Spades is used cautiously for depression because its sedative profile can deepen low-mood states in some users. Patients with treatment-resistant depression sometimes find the strain helpful, but it should be used under professional guidance rather than self-medication.
5. Appetite loss and nausea. The strain's strong appetite stimulation makes it effective for chemotherapy recovery, eating disorder management, and unintentional weight loss. Consumption 30 to 60 minutes before meals typically produces measurable appetite increase within the first hour of effect.
6. Muscle spasms and tension. Heavy myrcene content delivers muscle-melting relief that benefits patients with multiple sclerosis, severe menstrual cramps, and post-workout muscle tightness. Effects typically peak around 90 minutes and persist through the full session window.

Buying Authentic Ace of Spades Seeds

Following TGA Genetics' wind-down after Subcool's death, sourcing original-line Ace of Spades seeds has become considerably more difficult. The current market is dominated by S1 reproductions and backcrosses produced by preservationist breeders working from cuts obtained directly from TGA.

Authentic-feeling reproductions are available from several established European seedbanks at 70 to 130 euros per 5-seed pack, while original TGA-stock seeds occasionally surface in collector-tier listings at significantly higher prices. Suspiciously cheap packs under 40 euros under the Ace of Spades name should be approached with extreme skepticism.

Verification methods include comparing breeder credentials and asking whether the seedbank can confirm the parental cut history, requesting photos of recent grow-outs to verify phenotype consistency, and reading multi-year forum threads where original Ace of Spades is discussed alongside modern reproductions.

Standard seedbank protections apply — discreet shipping with stealth packaging, crypto and bank transfer payment options, germination guarantees with replacement policies, and shipping windows of 5 to 18 business days depending on origin and destination.

1. Identify breeders working with original genetics. Several preservationist breeders carry verified TGA cuts obtained during the brand's active years and produce S1 reproductions or backcrosses that maintain the original phenotype with reasonable accuracy. Research these breeders' provenance carefully before paying premium prices.
2. Verify seedbank reputation through community forums. Long-running grower forums like Rollitup, GrassCity, and dedicated TGA enthusiast threads provide the most reliable signal for distinguishing legitimate sellers from opportunistic counterfeiters. Look for consistent positive reports across multiple users over multiple years.
3. Inspect seed pack photography and packaging detail. Authentic original TGA packaging featured specific design elements that counterfeiters consistently fail to replicate. Modern S1 reproductions should ship in clearly branded breeder-specific packaging that identifies the reproducer rather than copying TGA branding.
4. Compare original, S1, and backcross pricing. Original TGA-stock seeds, when available, command premium prices because they cannot be replaced. S1 reproductions and backcrosses sit at lower price points and represent better value for cultivators primarily interested in growing the strain rather than collecting original genetics.
5. Read grow reports specific to the seedbank. Different vendors carry different reproduction lines that can vary noticeably in phenotype expression. Reading recent grow reports from the specific seedbank before ordering helps set realistic expectations for what the seeds will actually produce.
6. Confirm shipping and replacement policies. Verify delivery times, stealth packaging tier options, and germination warranty terms before paying. Reputable European seedbanks typically replace failed seeds within 30 to 60 days when the customer follows the published germination protocol and provides documentation.
7. Use seasonal promotions strategically. Major seedbanks run 20 to 30 percent discounts during 4/20, Black Friday, Christmas, and Green Wednesday promotions. Stacking these with referral codes can substantially reduce the effective cost.
