Purple Zamal x Zamaldelica is a high-energy, near-pure sativa hybrid from ACE Seeds, a breeder renowned for conserving and refining tropical landraces. True to its lineage, the cultivar leans decisively sativa in its architecture, chemistry, and experiential profile. It marries the rare Purple Zamal expressions of Réunion Island with the celebrated cerebral power of Zamaldelica, yielding a plant that is at once exotic, vigorous, and intensely uplifting.
Growers and consumers often seek this cross for its clarity, longevity, and kaleidoscopic terpene bouquet. The variety exemplifies old-world sativa traits—long bloom times, soaring stretch, and an ethereal, incense-forward aroma—while benefiting from modern selection that improves resin density and consistency. It is best suited for experienced cultivators and connoisseurs who appreciate a true tropical sativa journey from seed to smoke.
As a botanical profile, Purple Zamal x Zamaldelica tends to show high calyx-to-leaf ratios, airy spear-shaped flowers, and vibrant anthocyanins under cooler night temperatures. The flavors blend floral-lilac, citrus-zest, and sweet spice with tropical undertones, reflecting a terpene driver that is frequently terpinolene-dominant. When dialed in, this cross rewards patience with complex effects and a refined, long-lasting finish.
History and Breeding Background
ACE Seeds developed Purple Zamal x Zamaldelica to celebrate and stabilize a particular spectrum of Zamal expressions while injecting the electric potency associated with their Zamaldelica line. Zamal itself is a storied sativa from Réunion Island in the Indian Ocean, renowned for growth vigor and a clear, transcendental effect described in ethnobotanical accounts since at least the mid-20th century. Purple Zamal denotes Zamal plants showing strong anthocyanin pigmentation, often tied to altitude, genetic drift, and cool night temperatures.
Zamaldelica, one of ACE Seeds’ signature creations, blends Zamal genetics with powerful African and Southeast Asian sativas—most notably select Malawi and Thai lines curated by ACE. This composite amplifies resin production and psychoactive intensity, while retaining the soaring, long-duration experience typical of Zamal. By crossing Purple Zamal with Zamaldelica, ACE sought to unify purple coloration potential, high terpinolene bouquets, and an elevated, long-lasting mental effect.
While specific release dates can vary by batch and geography, Purple Zamal x Zamaldelica has generally been circulated as a limited or special project within ACE’s catalog. Such offerings allow ACE to test and preserve unique chemotypes before broad distribution. The result is a cultivar that honors landrace authenticity while offering a more consistent grower experience than unworked, wild-collected seed.
Genetic Lineage and Phenotypic Spectrum
Genetically, Purple Zamal x Zamaldelica leans extremely sativa, reflecting a lineage that traces to the tropics of the Indian Ocean and the equatorial belt of Africa and Southeast Asia. The Purple Zamal parent contributes gene pathways for anthocyanin expression, elongated internodes, and an effervescent, clean psychoactivity. Zamaldelica contributes heavier resin heads, a denser terpene load, and the signature heady power for which Malawi- and Thai-influenced hybrids are known.
In phenotype, expect tall frames with 2–3x stretch after the photoperiod flip, especially under strong light. Internodal spacing frequently falls in the 5–10 cm range in flowering, with branches that naturally seek lateral space to support spear-shaped clusters. Buds tend toward a high calyx-to-leaf ratio and moderate density—airier than modern indica-leaning hybrids but substantial for a true tropical sativa.
Purple phenotypes typically emerge when night temperatures drop below about 18–20°C (64–68°F), with more intense coloration below 16°C (61°F). These expressions can show lavender pistils progressing to deep violet calyxes by late bloom, contrasted by lime-green sugar leaves and metallic-orange stigmas. Green phenotypes are equally common and can be slightly faster to finish, often emphasizing citrus-herbal terpenes and an even lighter body sensation.
Appearance and Morphology
Plants are statuesque, with elegant, whip-like branches and a cathedral-like posture that can fill vertical space quickly. Stems are flexible but benefit from early trellising or multi-point support once flowering begins in earnest. The leaves are narrow and serrated, typically with 7–11 blades, showing a bright to medium green hue that may deepen as phosphorus uptake increases in mid-bloom.
Flowers form as segmented spears with pronounced foxtailing, especially toward the top colas, a hallmark of equatorial sativa morphology. Calyxes are small to medium and stack in a way that leaves air gaps, improving botrytis resistance compared to dense indica formations. Trichome coverage is plentiful for a tropical sativa, with long-stalked glandular heads and a resin sheen that intensifies noticeably after week 8 of bloom.
Under cooler nights or in phenotypes carrying strong purple alleles, anthocyanins can flood the bracts, delivering displays from lilac to royal violet. Pistils start cream to pale peach, darkening to orange-rust as the plant nears maturity. By harvest, the visual effect is dramatic—contrasting jewel tones, sugar-frosted trichomes, and elegant, tapering colas that signal a mature sativa of vintage character.
Aroma and Bouquet
The bouquet is layered and dynamic, often led by terpinolene’s high-note perfume: sweet citrus, lilac, fresh-cut herbs, and a hint of pine. Secondary tones include mango rind, green papaya, and lemongrass, pointing to limonene, β-ocimene, and myrcene contributors. Heavier basenotes emerge with warmth, offering sandalwood, light incense, and a peppery snap suggestive of β-caryophyllene.
Purple phenotypes tend to add berry-floral tones—think blackcurrant skin, violet candy, and faint grape peel—without veering into sugary candy. In warmer rooms, the profile can shift toward tropical-citrus and sweet spice; in cooler cure conditions, floral-incense facets sharpen, and the bouquet becomes more perfumed. The nose is assertive but elegant, with the sort of airy complexity often reserved for old-world sativas.
Aromatics intensify across the final third of flowering, with noticeable increases in terpene volatility as resin glands swell. Post-harvest, a slow cure accentuates the incense-floral signature while trimming grassy aldehydes. Well-cured flowers open with a kaleidoscope of bright top notes that remain stable in jars across 6–10 weeks of curing.
Flavor and Mouthfeel
The first impression on the palate mirrors the aroma: zesty citrus peel meets lilac-floral sweetness, lifted by wisps of pine and fresh herbs. As the vapor unfolds, tropical nuances surface—mango-papaya and hints of sweet melon—followed by a spicy, slightly peppered finish. The aftertaste is clean and persistent, often leaving a lingering floral-incense echo that encourages repeat sips rather than heavy pulls.
Purple phenotypes may add subtle berry tones reminiscent of tart blackberry or currant, especially noticeable on the exhale. Combustion tends to be smooth if the flowers are properly dried to 10–12% moisture content and cured slowly at 58–62% relative humidity. Vaporization at 176–190°C (349–374°F) maximizes floral and citrus top notes while minimizing harsh phenolics.
Mouthfeel is light-to-medium, never cloying, with a refined dryness that suits daytime sessions. Compared with dense dessert cultivars, this cross tastes brighter and cleaner, without heavy caramelized terpenes. Many enthusiasts report that the flavor sharpens and sweetens after week 4 of curing, with noticeable gains in clarity by week 6.
Cannabinoid Profile
While chemovars vary, Purple Zamal x Zamaldelica typically expresses a THC-forward profile with minimal CBD, consistent with its sativa heritage. Across reported tests of closely related ACE lines, THC commonly falls in the 17–23% range by dry weight, with CBD often below 0.5%. CBG is frequently detectable around 0.2–0.8%, reflecting biosynthetic flux from CBGA in sativa-dominant plants.
Given the African landrace influence, detectable THCV is possible in some phenotypes, although presence and levels can vary widely. In African-derived sativas generally, THCV values of 0.2–1.0% have been documented, but not every plant will express meaningful quantities. When present, THCV can modulate the subjective arc—often sharpening onset and reducing appetite—but expectations should be conservative unless lab results confirm it.
Overall potency skews cerebral and long-lasting rather than heavy or narcotic. The combination of moderate-to-high THC, trace minors like CBG, and a terpinolene-leaning terpene stack supports the cultivar’s reported clarity and duration. As always, local lab testing is the gold standard; growers should test each phenotype to verify cannabinoid and contaminant profiles, especially for medical use.
Terpene Profile and Chemistry
Terpinolene frequently leads the terpene ensemble in this lineage, a hallmark of many tropical and African sativas. In lab-tested samples of comparable ACE Seeds sativas, terpinolene often represents 30–45% of the total terpene fraction, translating roughly to 0.3–0.9% by dry weight when total terpenes sit around 1.0–2.5%. This aligns with the variety’s lilac-citrus, pine-herbal top notes and its racy, clear-headed effect.
Secondary terpenes commonly include β-myrcene (0.2–0.6% by weight), limonene (0.1–0.4%), β-ocimene (0.05–0.3%), and β-caryophyllene (0.1–0.3%). Linalool, humulene, and α-pinene often appear in trace-to-minor amounts that nevertheless contribute noticeably to bouquet and effect stacking. Total terpene content in well-grown, slowly cured flowers tends to concentrate in the 1.2–2.0% range, with occasional outliers above 2.2% under optimal conditions.
From a pharmacologic perspective, terpinolene is associated with bright, creative, and alert effects when paired with THC-dominant chemovars. Limonene and ocimene contribute citrus-tropical lift and may enhance perceived mood elevation, while caryophyllene (a CB2-binding sesquiterpene) can add a grounding counterpoint. The net result is an effervescent terpene matrix that accentuates mental clarity over heaviness or sedation.
Experiential Effects and Use Cases
Expect a rapid, sparkling onset within 5–10 minutes after inhalation, peaking around 30–45 minutes, and tapering gently for 2.5–4 hours. The effect is vivid, cerebral, and panoramic—users often report heightened color saturation, music appreciation, and idea flow. Body load is light-to-neutral, with minimal couchlock even at higher doses relative to many indica-leaning hybrids.
Mentally, the cultivar leans clear, motivated, and exploratory. Conversation, outdoor walks, creative projects, and long-form reading pair well with the headspace. Compared with heavier hybrids, anxiety risk is moderate: sensitive users should start low and titrate slowly to find a comfortable threshold.
At microdose levels (one to two small puffs), effects often center on mood lift and mental clarity without overt intoxication. At medium doses, euphoria and focus intensify, sometimes with a gentle, psychedelic edge typical of equatorial sativas. Very high doses can be overwhelming for novices—lead with respect and consider setting, hydration, and nutrition to optimize the experience.
Potential Medical Applications
While rigorous clinical data for specific cultivars are limited, the chemotype associated with Purple Zamal x Zamaldelica suggests several plausible use cases. The National Academies (2017) concluded there is substantial evidence that cannabis is effective for chronic pain in adults, though individual response varies. For neuropathic pain, multiple randomized trials show THC-dominant inhaled cannabis can reduce pain intensity by approximately 30% versus baseline in a subset of patients.
The cultivar’s bright, uplifting profile may support daytime mood and motivation for some individuals with low mood, fatigue, or anhedonia. Terpinolene-leaning sativas are anecdotally favored for focus-intensive tasks and creative work, though users with anxiety or panic disorders should proceed carefully due to the rapid, stimulating onset. Small, carefully titrated doses taken earlier in the day can limit sleep disruption and reduce the risk of jitteriness.
β-caryophyllene’s CB2 activity may contribute modest anti-inflammatory effects, potentially relevant for tension-type headaches or inflammatory conditions, though robust human data remain limited. Limonene has been investigated for anxiolytic and antidepressant-like properties in preclinical models, which may complement mood-elevating effects in THC-forward chemovars. As always, medical use should be guided by a clinician, with attention to drug–drug interactions and personalized dosing schedules.
Comprehensive Cultivation Guide: Indoors and Outdoors
Purple Zamal x Zamaldelica thrives in warm, bright environments that emulate its tropical heritage. Indoors, aim for 24–30°C (75–86°F) daytime and 18–22°C (64–72°F) nighttime, with a vapor pressure deficit (VPD) of 0.9–1.2 kPa in late veg and 1.2–1.5 kPa in mid-to-late flower. Relative humidity targets of 60–70% in veg and 50–60% in bloom help balance transpiration and mold risk.
Lighting intensity of 700–900 µmol·m⁻²·s⁻¹ PPFD in early flower, rising to 900–1,050 µmol·m⁻²·s⁻¹ by mid-flower, supports resin and terpene development. Daily Light Integral (DLI) of 35–45 mol·m⁻²·d⁻¹ is a good indoor benchmark with efficient LEDs. Outdoors, full sun at 6–8+ hours daily is ideal; in subtropical to tropical zones, expect explosive growth and substantial final size.
Substrate choice can vary: well-aerated peat/coco blends or living soil systems both work if drainage is excellent. Target pH 6.2–6.8 in soil and 5.8–6.2 in coco/hydro. Nutrient strength should be moderate: EC ~0.8–1.2 in veg and 1.2–1.6 in flower, with a focus on calcium and magnesium sufficiency to support rapid cell expansion.
Feed light nitrogen in early veg, then transition to balanced NPK by late veg; in bloom, emphasize P and K while avoiding heavy salt buildup. This lineage dislikes overfeeding—tip burn and clawing appear quickly if ECs run high. A 10–20% runoff protocol in inert media helps prevent accumulation and lockout.
Training is crucial due to 200–300% stretch potential after flip. Top once or twice in veg at the 5th–6th node, then use low-stress training (LST) and a two-layer trellis (10–15 cm spacing) to flatten the canopy. Many growers initiate flower at 20–30 cm plant height to finish with 90–120 cm tops, depending on pot size and headroom.
Photoperiod management can tame vigor: consider flipping to 11/13 (light/dark) instead of 12/12 to reduce stretch and better align with equatorial cues. Flowering typically runs 12–16 weeks (84–112 days) indoors, with some green phenotypes maturing closer to 11–13 weeks under optimized conditions. Outdoors at 25–35° latitude, harvest windows often land late October to mid-November; tropical climates can allow multiple annual cycles if daylength and weather cooperate.
Yield potential scales with root volume and training. Indoors, 350–600 g·m⁻² is realistic under 600–700 W of high-efficiency LED in a 1.2 × 1.2 m tent with a well-managed SCROG. Outdoors in long-season climates with 50–100 L containers or in-ground beds, individual plants can exceed 1–2 kg of dry flower with season-long care.
Pest and disease considerations center on the long flowering window. Airy sativa buds resist botrytis better than dense indica colas, but 12–16 weeks in flower increases cumulative exposure to powdery mildew and mites. Implement integrated pest management (IPM): weekly scouting, sticky cards, and preventative biologicals like Bacillus subtilis (PM) and predatory mites (Phytoseiulus, Amblyseius) where legal and available.
Irrigation should favor deep, infrequent waterings that encourage robust root penetration, especially in fabric pots. In coco, aim for 1–3 irrigations daily in late flower depending on pot size, keeping 10–15% runoff to stabilize EC. In soil, allow the top 2–3 cm to dry between waterings; a moisture meter helps avoid both over- and under-watering.
For CO2 enrichment, 900–1,100 ppm during lights-on can enhance growth and yield if light, nutrients, and water are non-limiting. Keep canopy temperatures on the higher end of the recommended range when supplementing CO2 to sustain enzymatic activity. Monitor leaf surface temperature with an IR thermometer to avoid hidden heat stress under intense LED arrays.
Phenohunting tips: Purple phenotypes often show cooler night preferences and slightly slower maturation, with bolder floral-berry aromatics. Greener phenos may finish earlier with more citrus-herbal drive and an extra notch of cognitive clarity. Clone promising mothers early, as some tropical sativas root more slowly; 10–14 days to visible roots at 24–26°C with mild auxin gel is common.
Harvest, Drying, and Curing
Maturity cues differ from indica-leaning hybrids: do not wait for heavy amber trichomes if you want the brightest, most uplifting effect. Harvest when most gland heads turn cloudy with 5–10% amber, and pistils have largely receded—often between weeks 12 and 15 from flip for typical phenos. Calyxes swell late on this cultivar; a meaningful bulk-up often occurs in the final two weeks.
Dry slowly to protect terpinolene and monoterpenes, which volatilize rapidly at high temperatures. Target 18–20°C (64–68°F) and 55–60% RH for 10–14 days in the dark with gentle air movement below canopy level. Branch-hang or whole-plant hang methods can improve even drying on the speared colas.
Cure in airtight glass at 58–62% RH, burping jars daily for the first 10–14 days, then weekly thereafter. Many growers notice a striking improvement in incense-floral definition between weeks 4 and 8 of cure, with the sharpest, sweetest nose peaking around week 6. Proper cure reduces chlorophyll harshness, stabilizes moisture, and enhances burn quality, improving flavor transfer by anecdotally 15–30% versus quick-dried samples.
Trim strategy: Dry trim preserves volatile aromatics better for this lineage, especially if ambient conditions are well controlled. Use a light touch—these flowers often possess a high calyx-to-leaf ratio that makes aggressive trimming unnecessary. Store finished buds in cool, dark conditions; for every 10°C increase in storage temperature, terpene degradation rates can roughly double, so aim for ≤18°C when possible.
Data Snapshot and Practical Benchmarks
Vegetative pace is fast after week 3 from sprout; expect plants to reach 30–45 cm in 4–5 weeks with adequate light and nutrition. Typical internodal spacing ranges 5–10 cm in flower under 700–900 µmol·m⁻²·s⁻¹ PPFD, stretching to 12–15 cm at lower light intensities. Stretch multiplier after flip commonly falls between 2.0× and 3.0× under 12/12, slightly lower under 11/13.
Nutrient EC targets: 0.8–1.0 in early veg; 1.0–1.2 late veg; 1.2–1.4 early flower; 1.4–1.6 mid flower; taper to 1.0–1.2 in the final 10–14 days. pH targets: soil 6.3–6.7; coco/hydro 5.8–6.1. Water temperature 18–21°C (64–70°F) optimizes dissolved oxygen and root health.
Terpene totals of 1.2–2.0% by dry weight are common in comparable ACE sativas, with terpinolene often 30–45% of the terpene fraction. THC frequently registers 17–23% in mature, well-grown samples from related lines; CBD typically remains <0.5%. Yield expectations: 350–600 g·m⁻² indoors SCROG; 1–2+ kg per outdoor plant in long-season, high-sun environments.
Environmental benchmarks: Veg RH 60–70%; flower RH 50–60%; late flower RH 45–55% to reduce mold pressure. VPD 0.9–1.2 kPa (veg), 1.2–1.5 kPa (flower). PPFD 700–900 µmol·m⁻²·s⁻¹ early flower, rising to 900–1,050 µmol·m⁻²·s⁻¹ mid-late flower for best resin and terpene expression.
Troubleshooting and Optimization
If plants claw or show tip burn, reduce EC by 10–20% and increase runoff volume to flush salts. Pale upper leaves with interveinal chlorosis can indicate magnesium demand—supplement with 30–60 ppm Mg and 80–120 ppm Ca, especially in coco. Purpling of petioles may be genetic but can also signal phosphorus issues; confirm with overall vigor, leaf turgor, and substrate pH before adjusting nutrients.
Excessive foxtailing late in flower can stem from high canopy temperatures or overly intense light. Lower PPFD by 10–15% or raise fixtures to maintain 26–28°C leaf surface temperature; confirm with an infrared thermometer. For stretch control, reduce day length to 11 hours of light and emphasize blue-rich spectra in early bloom.
Terpene fade is often a drying or storage issue—aim for 18–20°C and 55–60% RH in the dry room, and keep cure jars in a cool, dark space. For muted aroma in living soils, check that potassium and sulfur are sufficient in mid-late bloom; both support terpene synthesis. If anxiety-prone effects dominate the user experience, harvest slightly earlier (cloudy with minimal amber) and consider lower-temperature vaporization to emphasize floral over spicy phenolics.
Safety, Compliance, and Responsible Use
Always verify local laws before cultivating or possessing cannabis. In regulated markets, submit samples to accredited labs for cannabinoid, terpene, and contaminant testing (pesticides, heavy metals, molds). Long-flowering sativas spend more time in the environment—clean inputs and robust IPM are essential to meet safety thresholds.
For consumption, begin with low doses and wait at least 15–30 minutes between inhalations to assess personal response. Because the effect can be stimulating, reserve first trials for daytime or early evening and pair with hydration and a light snack. Avoid driving or operating machinery while under the influence, and store products securely away from children and pets.
If using for medical purposes, consult a healthcare professional familiar with cannabinoid therapies to tailor dose, route, and timing. Consider potential interactions with sedatives, antidepressants, and blood pressure medications. Document effects, dose, and timing to identify the most therapeutic window with the fewest side effects.
