CBD # 1 x Purple PCK 2002 is a mostly indica hybrid developed by ACE Seeds, designed to fuse the calm, clear-minded character of a modern high-CBD line with the color, resin density, and hashplant charm of a classic Pakistani Chitral Kush selection. Its breeding aims to deliver reliable CBD expression while preserving the vivid purple anthocyanins and berry–incense perfume for which Purple PCK is renowned. For growers, it offers a compact structure, quick indoor finish, and robust resin production without sacrificing the soothing, low-anxiety experience many CBD-forward users seek.
This cultivar typically finishes in 8–9 weeks of flowering indoors and is well suited to temperate and warm outdoor climates, where it tends to complete by late September to early October in the Northern Hemisphere. The plants are squat, with broad leaflets, short internodes, and a hashplant bud build that rewards careful humidity control late in bloom. The result is a visually striking harvest that balances therapeutic potential and sensory appeal.
In the jar, expect a blend of sweet berry, ripe plum, and earthy incense layered over a resinous base—an aroma profile that telegraphs its PCK heritage. On the palate, the smoke is smooth, with notes of dark fruit, gentle citrus zest, and a peppery finish common to beta-caryophyllene-dominant profiles. Consumers often describe effects as calm, centered, and physically relaxing without heavy intoxication, especially in CBD-dominant phenotypes.
History and Breeding Context
ACE Seeds, known for curating and stabilizing regional landrace expressions, has long championed Pakistan Chitral Kush selections for their resin, color, and mold tolerance. The Purple PCK 2002 parent represents an early-2000s keeper from ACE’s work with Chitral material—valued for deep anthocyanin expression, a red-berry bouquet, and a classic hash-plant morphology. This line has historically been used as a colorful, hardy donor that transmits reliable indica structure and fast finishing times.
CBD # 1, by contrast, reflects the modern push toward high-CBD chemotypes with minimal THC. Breeding programs producing CBD-dominant plants often target CBD:THC ratios in the 25:1 to 50:1 range, according to general seed industry references on cannabinoid-type development, to ensure predictably gentle psychoactivity and strong therapeutic utility. By combining CBD # 1 with Purple PCK 2002, ACE Seeds sought to anchor CBD’s gentleness to a visually and organoleptically rich indica chassis.
In a broader market sense, this hybrid responds to a consumer shift toward functional, daytime-suitable cannabis that still offers connoisseur-grade flavor. While THC-centric indicas like Mazar (Afghan x Skunk) have been celebrated for decades—often testing near or above 20% THC in breeder descriptions—CBD-forward indicas serve a different need state. The cross leverages the fast 56–63 day flowering common to hashplant indicas to deliver a cultivar that is both efficient for growers and approachable for users sensitive to THC.
Genetic Lineage and Heritage
The genetic backbone is a cross of CBD # 1 (a high-CBD, low-THC parent) with Purple Pakistan Chitral Kush 2002 (a colorful, resinous, mostly indica landrace expression). PCK brings the hallmark berry–incense aroma, thick trichome coverage, and rapid flowering associated with Pakistani and Afghan-adjacent hashplants. CBD # 1 contributes a dominant CBD biosynthesis allele set that can shift progeny toward CBD-rich or balanced chemotypes depending on segregation.
In terms of inheritance, growers can expect a distribution of chemotypes across CBD-dominant (Type III), balanced (Type II, ~1:1), and, less commonly, THC-leaning (Type I) individuals. Because one parent is strongly CBD-type and the other is a classic THC-type indica, F1 populations often present a mix, with a sizeable share leaning CBD-dominant due to CBD # 1’s influence. Phenotypic selection from cuttings allows cultivators to lock in the desired ratio and aromatic profile for production.
Structurally, the indica heritage is evident in 2–5 cm internodal spacing, broad leaflets, and a compact canopy that rarely exceeds 80–120 cm indoors without training. Purple pigmentation tends to appear reliably in late flower, especially with a day–night temperature differential of 8–12°C. The PCK side also lends above-average tolerance to inclement weather, an asset outdoors and in greenhouses where autumn humidity can spike.
Appearance and Plant Structure
CBD # 1 x Purple PCK 2002 grows short and sturdy, with thick petioles and a columnar main stem that supports dense, golf-ball-to-soda-can-sized colas. Lateral branching is moderate, making it a natural fit for Sea of Green (SoG) layouts or compact tent gardens. Leaves are broad and dark, often exhibiting a waxy cuticle that glints under strong light.
Anthocyanins commonly paint bracts and sugar leaves in deep violets and garnets during late bloom. Cooler nights (15–18°C) and adequate phosphorus–potassium availability enhance this coloration without harming vigor. Trichome coverage is heavy, with bulbous heads and short stalks typical of hash-leaning indicas, making the flowers look frosted even before peak ripeness.
Dried flowers retain their color well after a careful cure, standing out in the jar as purple-speckled nuggets with a tight manicure. Calyx-to-leaf ratio is favorable, reducing trim time and loss. The finished bag appeal is high, combining color, density, and a sticky resin feel that hints at solventless extraction potential.
Aroma and Bouquet
Pre-harvest, the bouquet opens with red berry, blackcurrant, and a faint citrus rind overlay, grounded by a woody, resinous base. Linalool and ocimene-laced floral tones can appear in some phenotypes, especially those that favor a more perfumed PCK side. When rubbed, the stems release a sweet-spice note reminiscent of cardamom and clove, an indicator of beta-caryophyllene and humulene interplay.
During drying, the aroma shifts slightly toward darker fruit—plum, dried cherry, and fig—while a classic hash cellar note develops. Proper slow-dry preserves volatile monoterpenes, which are prone to evaporate quickly if ambient temperatures exceed 20–21°C. A 10–14 day dry at 60% RH typically locks in the berry–incense profile with minimal ‘hay’ note.
In the jar, expect a layered nose: sweet top notes, earthy mid-tones, and a resinous, incense-like base. Compared to many modern dessert cultivars, this profile is less confectionary and more botanical, with spice and floral facets that evolve with cure. It’s expressive yet not overpowering, making it pleasant for users who prefer nuanced, less gassy bouquets.
Flavor and Palate
The inhale is smooth and fruit-forward, presenting blackberry jam, mulberry, and gentle citrus zest. Mid-palate, an earthy sweetness emerges alongside a pepper-clove tickle associated with beta-caryophyllene. Finishing notes often include cedar, faint sandalwood, and a lingering hash resin taste on the exhale.
Vaporization at 175–185°C highlights the brighter terpenes, bringing out limonene, ocimene, and linalool-driven floral facets. Combustion deepens the profile, accentuating myrcene’s herbal backbone and the woody bitters of humulene. A balanced cure of 4–6 weeks in 62% RH conditions generally produces the most coherent flavor arc.
The mouthfeel is medium-weight with a slightly oily texture owed to dense trichome resin. Users sensitive to harshness will appreciate the cultivar’s low astringency when properly flushed and dried. Compared with many indica hashplants, this cross is notably sweet and purple-fruit leaning, with spice rather than fuel in the base.
Cannabinoid Profile and Ratios
Because one parent is CBD-dominant and the other is a traditional THC hashplant, the cross can express multiple chemotypes. In practical terms, growers commonly see CBD percentages in the 8–16% range in CBD-dominant phenotypes, with THC from 0.3–4.0% yielding CBD:THC ratios of roughly 4:1 up to 20:1. Balanced 1:1 phenotypes may fall around 6–12% CBD and 6–12% THC, depending on environment and selection.
For context, seed industry references that describe cannabinoid-type breeding report typical CBD cultivars at 25–50:1 CBD:THC, while high-CBG types can sit at 80–100:1 CBG:THC. Crossing a CBD-type with a THC-type pulls the ratio toward balance, which is why this hybrid rarely maintains a 25+:1 ratio across a whole population. Instead, expect a spectrum centered on CBD-dominant and balanced outcomes unless stringent selection is applied.
Minor cannabinoids like CBC and CBG often register at 0.1–1.0% individually, with total minors adding 0.5–2.0% by weight. These figures vary with harvest timing, as later cuts can slightly increase CBN post-cure due to THC oxidation. As always, actual results depend on genotype, cultivation practices, and lab methodology; third-party testing is recommended for precise formulation and compliance.
Terpene Profile and Volatile Chemistry
Dominant terpenes typically include beta-myrcene, beta-caryophyllene, limonene, and humulene, with linalool and ocimene common as secondary contributors. In CBD-leaning indicas, myrcene frequently ranges around 0.5–2.0 mg/g of dry flower, while caryophyllene can appear in similar magnitudes, lending the pepper–clove warmth. Limonene often sits in the 0.3–1.2 mg/g window, supporting citrus brightness without overwhelming the berry core.
Ocimene and linalool add floral and fresh, green nuances that play especially well with the PCK fruit character. Humulene, a sesquiterpene related to hops, contributes woody and subtly bitter counterpoints that round the palate. Terpene totals in well-grown samples commonly land between 1.0–2.5% by weight, consistent with resinous indica hashplants.
From a process standpoint, the terpene balance is sensitive to drying and curing conditions. Keeping dry room temperatures near 18–20°C and relative humidity at 58–62% helps preserve monoterpenes, which volatilize faster than sesquiterpenes. Gentle handling during harvest and dry trimming can reduce trichome rupture, protecting flavor and aroma through cure.
Experiential Effects
CBD-dominant phenotypes deliver a calm, clear, and physically relaxing experience with muted intoxication. Users report reduced somatic tension, softer edges on stress, and a gentle mood lift within 10–15 minutes of inhalation. The headspace stays functional, often described as ‘present’ or ‘centered,’ making it suitable for daytime or early evening use.
Balanced 1:1 phenotypes introduce a warmer euphoria while retaining body ease, a combination many find compatible with light creative tasks or social relaxation. Psychoactivity is noticeable yet typically manageable, with fewer anxiety spikes compared to high-THC indicas. Duration averages 2–3 hours for inhaled routes, with a taper rather than a crash.
Compared to heavy THC hashplants, this cross is less sedating at moderate doses, although higher amounts can still encourage rest. The absence of racy edges makes it attractive to users sensitive to THC-induced palpitations or paranoia. As always, individual responses vary; starting low and titrating slowly remains best practice.
Potential Medical Uses
CBD-forward indicas like CBD # 1 x Purple PCK 2002 are often explored for stress modulation, muscle relaxation, and general somatic calm. CBD’s interaction with serotonin (5-HT1A) receptors and inflammatory pathways is well documented in the scientific literature, and users commonly report less perceived stress and bodily discomfort. The addition of beta-caryophyllene—an agonist at CB2—may synergize for peripheral anti-inflammatory effects in some individuals.
Balanced 1:1 phenotypes are frequently sought for neuropathic discomfort, spasms, and sleep initiation, as the small-to-moderate THC component can enhance analgesic perception and sedation. Terpenes like myrcene and linalool are associated with relaxing, anxiolytic sensations that may complement CBD’s effects. Patients often prefer these chemotypes in the late afternoon or evening.
Non-intoxicating CBD-dominant expressions may suit wellness users who need daytime relief without cognitive impairment. For those in regulated markets, precise dosing via vaporization or tincture made from lab-tested flower can offer predictable outcomes. Always consult local laws and medical professionals; cannabinoid responses are individual, and formal medical supervision is advisable for chronic conditions.
Comprehensive Cultivation Guide
Legal note: Cultivation laws vary widely. Verify and follow all local regulations before germinating, cultivating, or processing cannabis. The following guidance is horticultural in nature and intended for lawful cultivation contexts only.
Seeds and germination: Use fresh, properly stored seed and germinate at 24–26°C with 90–100% RH in a dome or between moist paper towels. Expect sprouts within 24–72 hours, with radicles reaching 1–2 cm before transplanting into starter plugs or small containers. Maintain gentle light (200–300 PPFD) for the first week to avoid stretch.
Vegetative growth: Provide 18/6 light with 350–500 PPFD and a DLI of 20–30 mol/m²/day. Keep temperatures at 24–27°C with 60–70% RH and a VPD of 0.8–1.2 kPa. Feed at EC 1.2–1.6 (700–1,000 ppm 500-scale) with a balanced veg nutrient; pH 5.8–6.0 in hydro/coco and 6.2–6.5 in soil.
Training and canopy management: The cultivar’s compact, indica structure responds well to topping once at the 4th or 5th node, then low-stress training to open the center. For SoG, run un-topped plants at 16–25 per m² with short veg. For SCROG, a single topping and 10–14 days of veg after the screen fills produce an even canopy and optimal light distribution.
Flowering: Transition to 12/12 with 700–1,000 PPFD and a DLI of 35–45 mol/m²/day. Flowering time averages 56–63 days indoors, with many phenotypes finishing by day 60. Keep temps 22–26°C day and 18–21°C night; a day–night delta of 8–12°C encourages purple coloration without stress.
Nutrition in bloom: Ramp EC to 1.6–2.0 (1,000–1,400 ppm 500-scale) by week 3 of flower, emphasizing P and K while maintaining adequate Ca and Mg. Avoid excessive nitrogen after week 3 to reduce leafiness and improve calyx expansion. Target pH 5.9–6.1 in hydro/coco and 6.3–6.8 in soil for optimal nutrient uptake.
Humidity and VPD: Run 50–60% RH in weeks 1–4 of flower, then 45–50% RH in weeks 5–7 to protect against botrytis in dense colas. VPD in late bloom should be 1.2–1.5 kPa to balance transpiration and resin preservation. Ensure strong, oscillating airflow above and below the canopy.
Irrigation strategy: In coco/hydro, irrigate to 10–20% runoff per event to prevent salt buildup, adjusting frequency based on pot size and root mass. In soil, water thoroughly when top 2–3 cm dry, aiming for full saturation and slow, even dry-backs. Overwatering is a common pitfall with indica hashplants; root zones prefer wet–dry cycles that pull oxygen into media.
Pest and disease management: The cultivar’s tight buds warrant proactive IPM against botrytis in humid regions. Use cultural controls—good spacing, defoliation of overcrowded interior leaves, and strong airflow—plus biologicals like Bacillus subtilis or Trichoderma where permitted. Scout weekly for mites, thrips, and aphids; sticky cards and magnified leaf checks help intercept early infestations.
Outdoor and greenhouse: In the Northern Hemisphere, transplant after the last frost when soil temps exceed 12–14°C. Plants generally finish late September to early October, earlier in warm, arid climates. Consider light-def techniques in greenhouses to ensure completion before autumn rains in coastal zones.
Yields: Indoors, expect 400–550 g/m² under efficient LEDs with dialed environment and training. Outdoors, single plants in 75–150 L containers or in-ground beds can produce 300–800 g per plant depending on season length and feed. Resin is plentiful, making the cultivar attractive fo
