CBD # 1 x Panama is a mostly sativa hybrid from ACE Seeds that marries a high-CBD donor line (CBD # 1) with the celebrated Panama sativa. The result is a clear-headed, uplifting cultivar designed to bring the energetic, tropical character of Panama into a calmer, more balanced cannabinoid framework. For growers and consumers seeking daytime functionality with less THC intensity, this cross occupies a unique niche.
ACE Seeds is known for its preservation and refinement of classic landrace and sativa-dominant genetics. Their Panama line, in particular, has become a flagship for old-school Central American sativa effects and flavors. Crossing it with a CBD-forward parent was a deliberate attempt to modernize usability without losing the unmistakable personality of a storied sativa.
Within the current market dominated by very high THC varieties, CBD # 1 x Panama stands out. Many contemporary releases exceed 20% THC with minimal CBD, which can be challenging for sensitive or daytime users. This hybrid instead prioritizes balance, offering chemotypes that can emphasize CBD, deliver a 1:1 profile, or occasionally lean THC, depending on phenotype selection and testing.
That flexibility means this cultivar can be tailored to different goals with careful selection. Growers can choose CBD-dominant mothers to build a gentle, functional flower line, or they can select balanced ratios for broader appeal. Either way, the Panama backbone contributes vigor, electric clarity, and a clean tropical bouquet that has made Central American sativas legendary.
History and Breeding Rationale
The breeding rationale behind CBD # 1 x Panama is to fuse a classic, high-energy sativa effect with a more approachable cannabinoid ratio. ACE Seeds’ Panama is descended from old Panamanian lines long associated with the uplifting, euphoric qualities popularized by Panama Red in the 1960s and 70s. By introducing a CBD-rich donor (CBD # 1), breeders aimed to moderate THC’s sharper edges while preserving the motivational spark and incense-citrus bouquet.
Historically, Central American sativas like Panama and Colombian varieties defined the bright, cerebral side of cannabis. Leafly’s coverage of high-energy strains echoes what veteran consumers already know: certain sativas can boost motivation and help fight fatigue. The challenge for modern users is maintaining that energy without overwhelming intoxication, a balance that CBD can help achieve.
ACE Seeds has a long record of working with heirloom sativa genetics and bolstering them with careful selection. CBD-oriented breeding in the last decade has also matured, enabling more predictable CBD expression in seed populations. CBD # 1 x Panama represents the intersection of these two trajectories, offering a heritage experience with contemporary usability.
The cross also addresses practical cultivation goals. Panama lines are robust, adaptable, and mold-aware due to their sativa architecture, while CBD donor lines often deliver faster resin maturation and improved handling of stress. Together, they produce plants that are spirited yet manageable for both indoor and outdoor gardens.
Genetic Lineage and Heritage
As the name suggests, CBD # 1 x Panama is a direct cross between ACE Seeds’ CBD # 1 and their Panama. Panama itself consolidates elite Panamanian selections, often described in terms of red, green, or pink phenotypes that reflect slight differences in pistil color, resin character, and terpene accents. These selections are known for citrus-incense notes, clean euphoria, and tall, elegant growth.
The Central American sativa corridor has produced several iconic lines beyond Panama, such as Colombian Gold from the Santa Marta mountains. While Colombian Gold is distinct, it shares the fluffy, crystal-laden morphology and soaring effect profile associated with classic landrace sativas. This regional context helps explain why Panama contributes such clear, buoyant energy to the cross.
CBD # 1 serves as the high-CBD anchor. CBD donor lines are typically stabilized for elevated cannabidiol expression, helping shift progeny away from Type I (THC-dominant) chemotypes. When combined with a strong sativa like Panama, the resulting seed population can segregate into CBD-dominant, balanced, and occasionally THC-leaning chemotypes, which underscores the importance of phenotype selection and lab verification.
Genealogical mapping tools used by breeders and archivists—such as those cataloging seed genealogies and hybrids—illustrate how quickly crosses proliferate. In this case, ACE Seeds retained tight control over the parents to protect the Panama identity while introducing CBD. The outcome is a well-conceived hybrid that reads as Panama in the garden and on the palate, yet behaves more gently in the mind.
Morphology and Appearance
CBD # 1 x Panama presents a classic sativa architecture: vigorous vertical growth, medium internodal spacing, and elongated spears of flower. Plants typically stretch 2x to 3x after the flip indoors, finishing between 1.2 and 2.0 meters under common ceiling heights when trained. Outdoors, with long-season sun, heights of 2.5 to 3.5 meters are achievable in rich soil and large containers.
Buds are airy to medium-dense, with a tendency toward conical or foxtailing tips in late flower if lighting intensity is high. The calyx-to-leaf ratio is favorable, easing manicuring, and trichomes are abundant yet less clumpy than indica-dominant resin. Panama-derived pistils can display warm hues near harvest, occasionally leaning coppery or reddish, a visual wink to Panama Red heritage.
Leaf morphology skews narrow-lobed and lime to forest green, with moderate serration and a slightly glossy cuticle. Stems are sturdy but benefit from staking or trellising during mid-to-late flower due to the long cola structure. The overall impression is sleek and athletic, optimized for airflow, light penetration, and swift resin maturation across tall inflorescences.
Under proper nutrition, bracts swell appreciably in the final three weeks, and resin heads become glassy-white, then increasingly cloudy. Sugar leaves remain relatively thin, minimizing post-harvest trimming labor. The finished flowers are visually kinetic—less about brute density and more about elegant length, crystalline shimmer, and interlaced pistil color.
Aroma and Bouquet
The bouquet is bright, layered, and unmistakably tropical-sativa. Expect a core of citrus zest and lime peel wrapped in incense and aromatic woods, with side notes of pink pepper, anise, and floral sweetness. As plants mature, a faint strawberry or guava nuance can appear, especially in phenotypes leaning toward the Panama pink side.
Breaking a cured flower releases an effervescent citrus-cloud: limonene and terpinolene hints leading the way, grounded by herbal sweetness and a touch of bay leaf. Freshly ground buds often show a jump in piney top notes and green mango. The overall aromatic impression is clean, uplifting, and sophisticated rather than candy-sweet.
Environmental conditions modulate expression noticeably. Cooler late-flower nights intensify wood and incense components, while warmer steady temps emphasize citrus and tropical fruit. Outdoor-grown flowers, contrary to common myths, can be as terpene-rich as indoor, and sometimes more, when managed well and harvested at peak maturity.
Flavor and Palate
On the palate, CBD # 1 x Panama is crisp and aromatic, with citrus oils leading into sandalwood, bay, and a dry herb finish. The first impression is lemon-lime sparkling water, followed by juniper and white pepper that linger on the tongue. A soft sweetness appears on exhale, reminiscent of pink grapefruit and light honey.
Combustion and vaporization each express the profile differently. Vapor at 175–190°C (347–374°F) brings forward terpinolene’s bright, green fruit character and limonene’s citrus pith, with clear pinene lift. Combusted flower emphasizes incense and spice, leaving a clean, resinous finish without cloying aftertaste.
Cure length strongly influences nuance. A 14–21 day slow cure at controlled humidity unlocks deeper wood resins and softens any raw chlorophyll edge. Overly rapid drying can flatten citrus and erase the delicate floral accents that make Panama descendants shine.
Cannabinoid Profile and Chemotypes
CBD # 1 x Panama is designed to broaden chemotype possibilities beyond typical Type I THC-dominant sativas. Seed-grown populations can segregate into three practical outcomes: CBD-dominant Type III, balanced Type II (roughly 1:1), and less commonly THC-leaning Type I. The balance you see in finished flower depends on selection, environmental factors, and post-harvest handling.
Based on analogous CBD-forward sativa crosses and breeder intent, reasonable expectations are: CBD-dominant phenotypes showing CBD around 10–18% with THC often between 0.2–4%; balanced phenotypes in the 6–10% CBD and 6–10% THC range; and occasional THC-leaners at 12–18% THC with 0.1–2% CBD. These are guide ranges, not guarantees, and must be confirmed with lab testing due to natural genetic recombination in seed lots. Total cannabinoids often register in the 12–24% window depending on phenotype and cultivation.
Minor cannabinoids commonly present in sativa populations include CBG (0.2–1.0%), CBC (0.1–0.5%), and trace THCV in some Panama-leaning plants. Heat and light stress during late flower can shift the acid-to-neutral cannabinoid balance, so careful drying and storage help preserve the intended profile. Decarboxylation of CBDA to CBD is complete by the end of a normal cure, but high-temperature extraction or baking accelerates conversion.
In market context, many modern strains carry very high THC and negligible CBD, exemplified by popular lines often listing over 20% THC with 0–1% CBD. CBD # 1 x Panama intentionally diverges from that pattern to support daytime usability and a wider therapeutic window. For medical intent or precise experience targeting, verified lab results and batch-specific terpene data are strongly recommended.
Terpene Profile and Volatile Compounds
A terpinolene-forward profile is likely in Panama-leaning phenotypes, supported by limonene and beta-pinene for lift and caryophyllene for spice. In lab-tested sativa samples of similar origin, terpinolene often ranges 0.3–0.8% by weight, limonene 0.2–0.5%, beta-pinene 0.1–0.3%, and beta-caryophyllene 0.2–0.5%, with total terpenes commonly in the 1.0–3.0% range. Myrcene and ocimene can appear as secondaries, offering tropical fruit and herbal depth.
Panama’s incense character suggests contributions from farnesene and linalool in some phenotypes, adding soft floral and green apple–like notes. When grown under high light intensity and balanced nutrition, terpene richness tends to increase, provided temperatures are controlled to avoid volatilization losses. Night temperature dips of 3–5°C near harvest can support terpene retention without compromising growth.
Outdoor cultivation can rival or exceed indoor terpene content when plants receive full-spectrum sunlight and careful post-harvest handling. Studies and grower reports indicate terpene loss can exceed 30% within three months of poor storage at room temperature, emphasizing the need for cool, dark, airtight conditions. Target final water activity between 0.55–0.65 to stabilize aroma and prevent microbial growth.
Because CBD # 1 x Panama may develop different chemotypes, growers should sample multiple tops for terpene testing to capture the plant’s integrated profile. Heavy defoliation early in flower can reduce leaf-driven terpene synthesis; instead, opt for selective thinning and robust airflow. Vaporization temperature stepping (170°C, then 185°C, then 200°C) can sequentially highlight citrus, floral, then spice-wood layers.
Experiential Effects and Use Cases
The experience is distinctly sativa in spirit: bright, focused, and gently euphoric, yet restrained by CBD’s moderating influence. Within minutes of inhalation, users often report mental clarity, increased task engagement, and a buoyant mood that avoids the jittery edge sometimes associated with high-THC sativas. Functional energy and reduced fatigue are consistent themes.
This tracks with broader observations about high-energy strains supporting motivation and activity. The CBD component can temper THC-induced heart rate increases and anxiety in sensitive users, aiding composure during productivity or social settings. Expect a clean onset in 2–5 minutes by inhalation, a plateau for 60–120 minutes, and a gentle taper over 2–4 hours.
Balanced 1:1 phenotypes feel mildly intoxicating but controlled, akin to a strong espresso with a calm finish. CBD-dominant phenotypes can be almost no-high for some users, with attention and mood uplift more than overt euphoria. THC-leaning phenotypes, while rarer in this cross, can approach classic Panama intensity, so dose accordingly.
Use cases include creative work, light exercise, walking or hiking, daytime chores, and social activity where conversation and presence are valued. Many users pair it with morning routines for a smooth start, or mid-afternoon to counteract slump without compromising evening wind-down. Edible preparations shift the curve: onset at 45–120 minutes, peak at 2–3 hours, and duration up to 6–8 hours, with CBD dampening THC’s peaks.
Potential Medical Applications and Safety
CBD-forward and 1:1 cannabis varieties are frequently explored for anxiety modulation, inflammatory pain, and stress resilience. Clinical data show CBD can reduce seizure frequency in certain epilepsies, with randomized trials reporting median reductions around 36–44% in Lennox–Gastaut and Dravet syndromes. While that’s a pharmaceutical context, it illustrates CBD’s neurological impact and safety profile at therapeutic doses.
For anxiety, human studies indicate an acute anxiolytic effect of CBD in the 300–600 mg oral range during stress paradigms, although outcomes vary and dose-response can be U-shaped. In daily-use contexts, inhaled CBD-rich flower delivers much smaller doses per session, often 5–50 mg of CBD depending on potency and inhalation technique. Many patients report perceived reductions in stress reactivity and improved stress-coping when using balanced or CBD-dominant flower.
For pain and inflammation, meta-analyses suggest cannabinoids offer modest improvements in chronic pain for some patients, with better tolerability than certain opioids but also variable efficacy. CBD’s interaction with TRPV1, 5-HT1A, and inflammatory pathways may contribute, while low-to-moderate THC can aid analgesia and mood. A 1:1 profile is often recommended anecdotally as a starting point for neuropathic pain, then adjusted based on response.
Safety considerations include potential drug–drug interactions. CBD can inhibit CYP3A4 and CYP2C19, affecting medications such as certain anticonvulsants, SSRIs, and proton pump inhibitors; medical guidance is essential if you take prescription drugs. Common side effects at higher CBD doses include fatigue, GI upset, and changes in appetite, while THC’s adverse effects—anxiety, tachycardia, short-term memory impairment—are generally mitigated at lower doses or higher CBD ratios.
Practical dosing approaches for flower often start with 1–2 inhalations, wait 10 minutes, then titrate. For edibles, start low (1–2 mg THC with 2–10 mg CBD), wait a full 2–3 hours, and increase slowly. As always, medical use requires individualized assessment, and lab-verified cannabinoid and terpene profiles provide the best foundation for predictable outcomes.
Cultivation Guide: Environment, Lighting, and Scheduling
CBD # 1 x Panama thrives in warm, well-ventilated environments with steady light intensity. Vegetative growth is vigorous in 24–28°C daytime temperatures with 55–65% RH, settling to 22–26°C and 40–50% RH in flower. Keep VPD around 0.8–1.2 kPa in veg and 1.2–1.6 kPa in flower for optimal transpiration and nutrient flo
