Macadelic is a contemporary hybrid developed by 0siris Genetics, a boutique breeder known for dialing in balanced indica/sativa works that play well in modern gardens. The strain’s name nods to both the popular MAC lineage in today’s market and the psychedelic, high-color experiences enthusiasts associate with terpene-rich hybrids. While 0siris Genetics has not publicly released a full pedigree, the cultivar’s popularity has grown quickly in North American craft circles since the early 2020s. That momentum reflects a broader consumer shift toward hybrids that deliver both clarity and weight without sacrificing terpene intensity.
The release strategy typical of small-batch breeders—limited drops, tester runs, and later stable releases—appears to have helped Macadelic build a reputation among phenohunters. Growers on social channels frequently mention early tester packs appearing in 2021–2023, followed by increasingly stable cuts in circulation. Interest has been fueled by reports of dense flowers, heavy resin, and a profile that oscillates between citrus-cream brightness and deeper, earthy spice. This blend of traits made it a compelling choice for extract artists and flower-first connoisseurs alike.
Culturally, the name “Macadelic” also resonates with listeners of Mac Miller’s 2012 mixtape, further embedding the cultivar in a modern, art-forward cannabis aesthetic. That association sends a clear message about the experience: colorful, immersive, and layered. In a market where naming affects perception, Macadelic communicates a deliberate promise of hybrid complexity. It has since become a talking point on menus where high-terpene hybrids are sought after for both taste and effect.
The strain’s adoption has been bolstered by a production profile that suits both indoor and greenhouse environments. Reports from small commercial rooms indicate that consistent 8–10 week flowering windows are achievable without sacrificing density or bag appeal. Yields, while phenotype-dependent, are competitive with contemporary hybrids when proper training and support are used. That combination of potency, aroma, and manageable cycle time helps explain Macadelic’s steady rise.
As legal markets mature, cultivars that balance novelty with reliability tend to persist. Macadelic fits that mold by offering a recognizable hybrid “middle path” anchored by indica structure and sativa lift. In collections where redundancy is common, its terpene-driven signature and malleable effects profile have kept it relevant. The result is a cultivar that bridges connoisseur and commercial priorities with uncommon finesse.
Genetic Lineage and Breeding Insights
0siris Genetics lists Macadelic as an indica/sativa hybrid, and community consensus treats it as balanced rather than strongly leaning either way. The precise parent lines are not formally disclosed by the breeder, a common practice when protecting proprietary breeding work. However, several grow reports and consumer notes point to morphological and terpene cues consistent with MAC-influenced material—think dense, resinous buds, citrus-cream aromatics, and a peppery finish. In this reading, Macadelic situates itself among MAC-descendant modern hybrids, with a more expressive citrus and spice axis.
Even without official parentage, phenotype behavior provides strong hints. Growers consistently describe a 1.5–2.0x stretch after the flip to 12/12, a hallmark of balanced stock that carries both indica compactness and sativa vertical push. Calyx-to-leaf ratios trend favorable for trimming, and internodal spacing tightens under high PPFD, which mirrors characteristics seen in MAC crosses. Resin heads are plentiful and often bulbous, favoring solventless extraction yields above the hobbyist average.
From a breeding perspective, Macadelic’s stability appears improved in later distributions. Early testers reported moderate pheno spread in aroma emphasis—some skewing toward lemon-lime zest, others toward creamy sweet spice—while structure and finishing time remained consistent. As drops matured, anecdotal reports suggest the cultivar locked into a narrower window: 63–70 days to full maturity, medium-tall stature, and a terpene cocktail anchored by limonene, caryophyllene, and myrcene. This convergence supports the view that 0siris selected for predictable cultivation behavior alongside a terp-saturated nose.
The balanced heritage aligns with contemporary consumer data showing demand for hybrids that deliver both euphoria and composure. In U.S. adult-use markets, hybrids routinely account for 45–55% of flower sales in a given quarter, outpacing pure indica or sativa labels. Macadelic’s breeding target places it squarely in this high-demand segment while differentiating through repeatable resin production and elevated citrus-spice expression. It is precisely the kind of cultivar that satisfies current palate trends without sacrificing agronomic efficiency.
For home breeders considering Macadelic as a parent, the cultivar’s apparent prepotency in resin and terpenes make it a useful donor. Its structure responds well to selection pressure for tighter internodes and heavier calyx stacking, traits that translate reliably in filial generations. When paired with gas-forward parents, Macadelic’s citrus-cream can brighten the blend; with fruit-forward parents, it can add depth via peppery caryophyllene. Either way, the underlying hybrid vigor and moderate stretch act as predictable anchors in a cross.
Botanical Appearance and Structure
Macadelic presents with medium to large colas comprised of dense, golf-ball to torpedo-shaped buds. The flowers display a high calyx-to-leaf ratio, typically in the 65–75% range by visual estimation, which reduces post-harvest labor. Under optimal light intensity, bracts swell conspicuously during weeks 6–8 of flower, producing a visibly “stacked” silhouette. Sugar leaves are modest in size, often curled tight into the resin field.
Coloration is classic hybrid: lime to forest-green hues punctuated by intermittent royal-purple streaking in cooler late-flower rooms. Anthocyanin expression increases when night temperatures are 3–5°C lower than daytime, especially in phenotypes with latent purple genetics. Orange to apricot pistils layer atop the green-purple base, maturing to a burnished copper as harvest nears. The aesthetic is unmistakably “modern market” with strong bag appeal.
Trichome coverage is abundant and dominated by capitate-stalked gland heads. On mature flowers, heads frequently average 80–100 microns in diameter, the sweet spot for quality hash separation. This trait manifests as a thick, frosty sheen that persists even after trimming. The visual density correlates with robust aroma release during grind and a sticky, tacky hand-feel.
Structurally, Macadelic grows with a medium internodal spacing that tightens substantially under high PPFD and proper plant training. Tops are weighty enough to require trellising by mid-flower, particularly in phenotypes that lean toward the cream-lime expression. Side branching is vigorous, supporting multi-top production in SCROG or manifold systems. Altogether, the plant’s architecture rewards proactive canopy management with a uniform, light-soaked table.
Aroma and Bouquet
Macadelic opens with a bright citrus top note that most tasters describe as lemon-lime zest with a faint candied sweetness. Beneath the citrus lives a creamy, almost vanilla malt tone that rounds the edges of the nose. A peppery, woody spice trails the exhale, giving the bouquet length and complexity. Together, these tiers present a layered, “dessert-citrus” profile that is easy to identify in a blind sniff.
Freshly ground flower amplifies the lemon peel and unlocks a resinous, slightly herbal undertone. Caryophyllene-driven spice steps forward, often registering as cracked black pepper or cedar shavings. With a few minutes of air, the cream note morphs toward sweet pastry or light nougat. This dynamic evolution suggests a terpene composition with both bright monoterpenes and stabilizing sesquiterpenes.
Jar testers repeatedly mention a “clean” nose with minimal funk, though some phenotypes show a faint diesel twang. The diesel hint likely reflects trace farnesene or fuel-adjacent minor volatiles arising from the genetic background. In cold-cured samples, the citrus persists strongly over several weeks if storage humidity is maintained at 58–62%. The bouquet’s durability is a practical advantage for retail presentation and at-home enjoyment.
When burned, the room note is welcoming rather than aggressive. The air fills with lemon cream, sweet grain, and a gentle pepper tail that does not overpower. This approachable aroma profile makes Macadelic a social-friendly cultivar that does not linger heavily on fabrics. It also signals efficient combustion with well-cured material, often producing a white to light-gray ash.
Flavor Profile and Mouthfeel
On the draw, Macadelic delivers a crisp lemon-lime sparkle that lands on the tip and sides of the tongue. Mid-palate, a silky cream motif lends body and turns the citrus into something akin to key lime pie or lemon custard. Subtle vanilla and honey biscuit notes show up as the bowl deepens. The finish is clean, with a peppery snap that refreshes rather than overwhelms.
Vaporization at 175–190°C preserves the brighter monoterpenes, emphasizing citrus peel and sweet cream. At higher temperatures (195–205°C), the spice and woody elements become more pronounced, and the cream moves toward toasted sugar. Dabbers of solventless rosin report a pronounced lime sherbet attack with a lingering white pepper echo. Across formats, the core identity remains intact: bright, creamy, and lightly spiced.
Mouthfeel is medium-bodied with a soft, coating texture that suggests a terpene fraction rich in oxygenated monoterpenes. The smoke is notably smooth for a citrus-forward cultivar, likely a function of balanced curing and caryophyllene’s gentle warmth. Palate fatigue is low, allowing for extended sessions without flavor collapse. This resilience makes Macadelic a strong candidate for taste-first consumers.
Pairing-wise, the profile shines alongside sparkling water with a twist of lime, green tea, or lightly sweet pastries. Savory pairings with grilled poultry or herbed fish also work, where the peppery finish complements seasoning. Home infusion enthusiasts note that the citrus-cream translates well into clarified-butter extractions for desserts. The terpene balance keeps flavors from turning bitter in fat-based preparations.
Cannabinoid Composition and Potency Data
As a modern hybrid, Macadelic typically tests with high THC and minimal CBD. Across reported third-party certificates of analysis in similar balanced hybrids, THC commonly ranges from 20% to 27% by weight, with standout phenotypes reaching the upper 20s. CBD generally remains below 0.5%, often testing under the 0.2% quantification threshold. Minor cannabinoids, particularly CBG and CBC, tend to appear in the 0.2–0.8% combined range.
Given natural variability, it is best to treat potency as a range rather than a fixed point. Factors like light intensity, nutrient strategy, and harvest timing can shift THC by several percentage points. In side-by-side indoor trials, increases in average PPFD from 700 to 1000 µmol·m⁻²·s⁻¹ with adequate CO2 have been associated with 5–10% relative increases in total cannabinoid content. Similarly, late-harvest windows can boost THC-a to THC conversion, slightly affecting results after decarboxylation.
For extractors, Macadelic’s high resin density correlates with extraction-friendly metrics. Solventless wash yields from comparable resin-rich hybrids routinely land in the 3–5% yield-from-flower range for premium heads, with exceptional material touching 6% or better. Hydrocarbon extraction can recover a greater fraction of total resin, reflected in higher overall yields at the cost of broader selectivity. The cultivar’s bulbous gland heads and robust cuticle often translate to clean separations and stable textures.
Edible formulations should consider the cultivar’s potency consistency when scaling dosage. A common home decarb of 240°F (115°C) for 40–45 minutes converts a significant fraction of THCA, but process losses of 10–20% are normal in kitchen settings. Given THC ranges and process variability, accurate dosing demands careful math and, ideally, small-batch potency checks. Consumers should start low to accommodate both potency and the cultivar’s energizing top notes.
In markets that publicly report lab averages, balanced hybrids comprise the majority of top-selling SKUs, and many cluster in the 22–26% THC band. Macadelic’s reported potency aligns with this competitive tier. The consistency of mid-20s THC, paired with a terpene fraction commonly exceeding 2% by weight, positions the cultivar as both strong and flavorful. This dual profile is a key driver of contemporary consumer preference.
Terpene Spectrum and Chemistry
Macadelic’s aroma suggests a terpene matrix anchored by limonene, beta-caryophyllene, and myrcene. In analogous citrus-cream hybrids, total terpene content typically spans 1.5–3.0% by weight, with limonene commonly occupying 0.5–0.9%. Beta-caryophyllene often trails at 0.4–0.8%, providing the peppery backbone and interacting with CB2 receptors. Myrcene is frequently measured between 0.3–0.7%, lending body and a faintly herbal sweetness.
Secondary contributors likely include linalool, humulene, and ocimene in smaller amounts. Linalool in the 0.1–0.2% range adds floral lavender hints that soften citrus edges. Humulene at 0.1–0.2% reinforces woody dryness and pairs synergistically with caryophyllene in anti-inflammatory contexts. Ocimene and farnesene may surface in trace levels, offering fruity lift or a green, apple-skin brightness.
From a sensory chemistry standpoint, limonene drives the top note volatility, explaining the immediate lemon-lime character upon opening a jar. Caryophyllene, a sesquiterpene, volatilizes more slowly and extends the finish with a gentle spice that persists after exhale. Myrcene contributes to perceived depth, connecting bright and woody layers so the profile feels cohesive rather than scattered. This multi-weight volatile blend explains the nose’s evolution over time in the glass.
There is increasing interest in how specific terpene ratios influence subjective effects. Studies indicate limonene can elevate mood and perceived energy, while caryophyllene’s CB2 activity may modulate inflammatory signaling and anxiety responses. Myrcene, depending on dose and entourage, can lean sedative, particularly when paired with THC above 20%. Macadelic’s balance of these three often reads as uplift-then-unwind for many users.
Storage has a measurable impact on terpene preservation. At 20–22°C and 58–62% RH, terpenes degrade noticeably across several months, with monoterpenes like limonene showing faster loss rates. Refrigerated storage in airtight, UV-protected containers can significantly slow this decline, preserving both aroma and flavor. For long-term holders, minimizing oxygen exposure is the single most important step to maintain Macadelic’s citrus-cream vibrancy.
Experiential Effects, Onset, and Duration
Most users describe a two-phase experience that starts with clean cerebral lift and transitions into body-centered calm. The initial 10–20 minutes often bring brighter mood, easier conversation, and a gentle increase in sensory detail. As the session continues, a grounded warmth spreads through the shoulders and torso without heavy couchlock. This arc aligns with the cultivar’s balanced indica/sativa tag.
Onset depends on route of administration. Inhalation typically manifests within 2–5 minutes, peaks by 30–45 minutes, and tapers over 2–3 hours. Vaporized flower trends slightly smoother and clearer in the head, while combustion can feel marginally heavier in the body. Edibles present much slower, with onset commonly at 60–120 minutes and durations of 4–8 hours.
Subjective potency is consistently high due to THC levels and terpene drive. Newer consumers should consider 1–2 small inhalations and wait 10 minutes before redosing, especially with terpene-rich samples above 2% total terpenes. Experienced users often find Macadelic suitable for late afternoon into evening, where productivity can transition into relaxation. Creative tasks, casual socializing, and flavor-focused sessions are frequent use cases.
Reported side effects are typical for high-THC hybrids. Dry mouth occurs in roughly 20–30% of users, and red eyes in about 10–15%, based on self-reported consumer surveys for similar cultivars. Transient anxiety or rapid heart rate may occur in sensitive individuals, particularly at higher doses or in stimulating settings. Slow titration and hydration mitigate most minor adverse effects.
Tolerance dynamics mirror other modern hybrids. Near-daily use can blunt the euphoric peak over 1–2 weeks, requiring higher doses to reach the same subjective effect. Short breaks of 48–72 hours often reset sensitivity meaningfully for many people. Rotating cultivars with different terpene anchors can also help prevent monotony and tolerance creep.
Potential Medical Applications and Risks
Macadelic’s mix of limonene, caryophyllene, and myrcene, paired with robust THC, suggests potential utility across mood, pain, and sleep-adjacent concerns. Limonene has been associated in preclinical and limited clinical contexts with uplifted mood and reduced stress perception. Caryophyllene’s role as a CB2 agonist indicates possible anti-inflammatory and anxiolytic contributions without classic CB1 intoxication. For some patients, this translates into smoother edges on THC’s psychoactivity.
In pain contexts, user reports most often cite relief for musculoskeletal discomfort and tension headaches. The body-warmth phase approximately 30–60 minutes after inhalation can ease stiffness without immediate sedation. For neuropathic pain, responses vary, but the cultivar’s potency can make it a candidate when lower-THC options fail to provide relief. As always, non-inhaled routes may be preferable for chronic symptoms requiring steadier plasma levels.
Sleep-related outcomes tend to be dose-dependent. Light evening inhalation may relax without knockout, while higher doses shift the balance toward drowsiness due to myrcene and overall THC burden. Edible preparations can help sleep-maintenance issues by providing longer duration, though next-day grogginess is a risk at excessive doses. Patients should titrate carefully and consider timing relative to bedtime.
For anxiety, results are mixed and individualized. Some users experience calmer, brighter affect with small doses, attributing relief to limonene and caryophyllene synergy. Others may find high-THC stimulation uncomfortable during the fast-onset window. Structured dosing—starting at 2.5–5 mg THC orally or 1–2 inhalations—helps gauge personal response.
Potential risks mirror those of other high-THC, terpene-rich cultivars. Overconsumption can lead to acute anxiety, tachycardia, and dizziness, especially in naïve users. Interactions with medications metabolized by CYP450 enzymes are possible; patients should consult healthcare providers if using drugs like warfarin, certain SSRIs, or benzodiazepines. Individuals with a history of psychosis or severe anxiety disorders should approach cautiously or avoid high-THC products entirely.
From a harm-reduction standpoint, macrodosing is rarely necessary to obtain benefits from Macadelic’s chemotype. Splitting sessions into small increments reduces risk and often improves therapeutic ratio. Vaporization minimizes smoke-related respiratory irritants and allows finer control of onset and intensity. Hydration and a calm environment further reduce adverse outcomes.
Comprehensive Cultivation Guide
Macadelic responds exceptionally well to dialed environments and modern training. Indoors, target day temperatures of 24–26°C in veg and 22–25°C in flower, with night drops of 2–4°C. Relative humidity should track 65–70% in early veg, 55–60% in late veg/early flower, and 45–50% from week 6 onward. VPD targets of 0.8–1.1 kPa in veg and 1.1–1.4 kPa in flower help drive transpiration without stress.
Lighting intensity is a prime yield driver. Aim for 400–700 µmol·m⁻²·s⁻¹ PPFD in veg and 800–1000 in flower for non-CO2 rooms, stepping up to 1000–1200 PPFD if supplementing CO2 at 800–1200 ppm. Maintain even canopy distribution to avoid hot spots and larf. Photoperiod standards apply: 18/6 in veg and 12/12 in flower.
Root-zone parameters should be stable and oxygenated. In soilless or hydroponic systems, maintain pH at 5.8–6.2; in living or amended soils, 6.2–6.8 is appropriate. Electrical conductivity typically ranges 1.2–1.6 mS/cm in veg, rising to 1.8–2.2 mS/cm in peak flower, depending on cultivar hunger and medium. Ensure 10–20% runoff in inert media to prevent salt buildup.
Training strategies capitalize on Macadelic’s moderate internodal spacing and 1.5–2.0x stretch. Top at the 4th–6th node, then employ low-stress training to create 8–16 evenly spaced mains. SCROG nets or double trellis are recommended by the end of week 3 flower to support swelling colas. Strategic defoliation at late veg and day 21 of flower improves airflow and light penetration; follow with a lighter cleanup around day 42 if needed.
Vegetative timelines are flexible but impactful. A 21–28 day veg from rooted clone commonly produces plants 45–70 cm tall at flip, finishing 75–120 cm depending on phenotype and training. Longer veg times reward advanced growers with larger, more uniform canopies when coupled with aggressive topping. Maintain consistent node spacing by keeping daily light integral (DLI) in the 25–35 mol·m⁻²·day⁻¹ range during veg.
Flowering typically completes in 63–70 days, with many growers harvesting around day 65 for maximal citrus brightness. Phenotypes that lean cream-spice can benefit from 68–70 days to deepen secondary notes. Watch trichomes with a jeweler’s loupe: 5–10% amber, 80–90% cloudy, and minimal clear is a common target for balanced effects. Pistils should be 80–95% browned and receded on mature colas.
Nutritionally, Macadelic appreciates a balanced program. In veg, prioritize nitrogen and calcium-magnesium to support rapid leaf production and stem strength. Transition feeds should increase phosphorus and potassium beginning late week 2 of flower, peaking around weeks 4–6. Many growers taper nitrogen slightly after the stretch to tighten flower sites and improve resin expression.
Irrigation cadence should avoid extremes of wet and dry. In coco at 20–30% perlite, once to twice-daily fertigation works well once roots occupy the container. In soil, water thoroughly to gentle runoff, then allow the top 2–3 cm to dry before the next cycle. Oxygen-rich roots translate directly to denser buds and reduced risk of root pathogens.
Integrated pest management is non-negotiable. Implement weekly scouting under the canopy and on leaf undersides, focusing on hot spots like intake vents and doorways. Yellow sticky cards help monitor fungus gnats and flying pests; beneficial predators like Amblyseius cucumeris and Hypoaspis miles can be introduced preventatively. Maintain cleanliness, quarantine new clones, and use HEPA filtration to reduce pest and pathogen pressure.
Yields reflect environment, training, and phenotype selection. Indoors, 400–600 g/m² is a realistic range under 800–1000 PPFD with optimized conditions, while dialed rooms with CO2 may exceed 600 g/m². Outdoor or greenhouse plants can produce 600–1000 g per plant with ample root volume and full sun. Resin saturation makes Macadelic particularly attractive for solventless hash makers, improving crop value beyond raw flower weight.
Post-harvest handling determines how much of Macadelic’s citrus-cream survives the dry. Target a slow dry at 15–18°C and 58–62% RH for 10–14 days, with gentle airflow and darkness. Stems should snap rather than bend before trimming and jarring. Cure in airtight jars at 62% RH, burping daily for the first week, then weekly for 3–4 weeks; water activity in the 0.58–0.62 range preserves terpenes while preventing mold.
Phenohunting tips can help lock in your favorite expression. When popping seeds, run at least 6–10 individuals to observe the spread in citrus intensity, cream body, and spice finish. Keep detailed notes on stretch, internodal spacing, and resin head size; solventless-focused growers should wash small test batches to identify premium hash phenos. Retain vigorous, disease-resistant plants with strong aroma even before cure.
Common pitfalls include overfeeding late flower, which can mute the bright citrus with excess chlorophyll and residual salts. Another is insufficient support; the cultivar’s colas are heavy enough to flop without netting, which reduces light uniformity and density. Finally, harvesting too early can cost both weight and depth of flavor. Patience through week 9 for cream-forward phenos often pays dividends in both aroma and potency.
For sustainability-minded cultivators, consider living soil and LED fixtures to reduce inputs and heat load. LEDs delivering 2.5–3.0 µmol·J⁻¹ efficiency lower power draw while maintaining high PPFD, and living soils recycle nutrients through microbial action. Water-use efficiency also improves with proper mulching and drip systems. Macadelic’s cooperative structure and resin resilience make it a strong fit for these eco-forward systems.
Whether grown from clone or seed, cleanliness, consistency, and data logging are your compasses. Track EC, pH, VPD, PPFD, and runoff metrics to catch trends early. Photos of nodes, leaf posture, and trichome progression build a reference library unique to your environment. Over a few cycles, this feedback loop converts Macadelic from promising to reliably outstanding.
