3DG13 by Antenna Seeds: A Comprehensive Strain Guide

History and Breeding Origins

3DG13 is a boutique hybrid credited to Antenna Seeds, a small-batch breeder known for creative recombinations of classic Californian and legacy clone-only lines. The strain’s name hints strongly at its parentage, blending 3D, short for The Third Dimension, with the fabled G13 line. While Antenna Seeds keeps a minimalist public profile, community cataloging and naming conventions align with a 3D × G13 conceptual framework. That lineage sets expectations for a citrus-forward, terpinolene-influenced top note paired with the deep, earthy resin and body-weight of G13.

The release period for 3DG13 lines up with a wave of 2000s–2010s breeders repopularizing Apollo and Jack-influenced citrus profiles. Antenna Seeds’ approach focused on seed runs that preserved vigor and hybrid punch rather than marketing hype or limited releases. As a result, 3DG13 did not explode across social feeds but earned a steady, niche following among home growers and connoisseurs who valued its fast finish and potent evening-to-late-afternoon utility. The name also helped it stand out in seed catalogs, where “G13” carries a mythos that signals heavy resin and knockout performance.

The G13 story is part folklore, part fact, often linked to 1970s university breeding programs and Afghani provenance. Regardless of the legend, modern G13-based lines tend to express broadleaf-dominant morphology, thick resin heads, and a sedative, hashy baseline effect. 3D, by contrast, is tied to Apollo 13 and Jack the Ripper/Jack’s Cleaner genetics, contributing zingy citrus, pineapple, and a brisk, uplifting onset. 3DG13 seeks to marry those two worlds, delivering a fast, aromatic hybrid that still carries weight and finish in the body.

By placing The Third Dimension’s bright top end on a G13 chassis, Antenna Seeds targeted growers who wanted a reliable 8–9 week hybrid with modern bag appeal. The objective was not just potency but a layered terpene experience that holds up after curing and retail shelf time. Over time, 3DG13 gained a quiet reputation for being pragmatic in the garden and generous in the jar. Its stability and approachable cultural requirements made it a solid bridge between hobbyists and intermediate gardeners aiming for consistent results.

Genetic Lineage and Phenotypic Expectations

Most community reports and naming conventions identify 3DG13 as a cross of The Third Dimension (3D) and a G13-derived parent. The 3D side is widely associated with Apollo 13 and Jack’s Cleaner/Space Queen influence, a combination that typically shows terpinolene- and limonene-forward bouquets, rapid veg vigor, and an upbeat headspace. The G13 side introduces broadleaf structure, shortened internodes, and thicker resin coverage with hashy, woody undertones. Together, the hybrid tends to present a sativa-leaning terp profile on a sturdier, indica-leaning frame.

Phenotypically, cultivators should expect moderate stretch, often 1.5× to 2× after the flip to 12/12, which is milder than pure Haze or Jack lines but more pronounced than pure Afghani varieties. Leaf morphology skews hybrid, with medium-width leaflets that can broaden later in flower as G13 expression sets in. Calyx-to-leaf ratio is usually favorable, leading to easy trim and attractive calyx stacking. Resin heads are plentiful and sticky by week 6, with a notable jump in terp pungency between weeks 7 and 8.

Given a 3D × G13 blueprint, flowering time commonly lands between 56 and 63 days indoors, with some phenotypes wanting 65 days to maximize terp development and density. Outdoor and greenhouse settings often finish by late September to early October in temperate zones, making it earlier than long-flowering sativa types. Yield potential is medium-high when trained properly, with indoor harvests commonly reported in the 450–600 g/m² range under competent lighting. Individual outdoor plants can surpass 600–1000 g per plant in well-amended soil with a long veg and full sun.

Chemotypically, anticipate a THC-dominant profile with CBD as a minor component. Parents with Apollo/Jack ancestry rarely pass significant CBD, and G13 derivatives typically sit in the low-CBD, high-THC class. Expect a target THC window around 19–24% in well-grown batches, with outliers above or below depending on phenotype and cultivation variables. Total terpene content often falls between 1.5% and 2.5% by dry weight, with terpinolene, limonene, myrcene, and beta-caryophyllene frequently leading the pack.

Visual Appearance and Bag Appeal

3DG13 generally produces medium-density flowers that balance spherical and conical forms, reflecting its hybrid lineage. Buds are lime to forest green, with olive undertones deepening as the flowers mature. Rust-orange pistils weave densely through the calyxes, providing warm contrast against glistening capitate-stalked trichomes. The overall trim finish tends to be clean due to a favorable calyx-to-leaf ratio.

In colder night temperatures late in flower, some phenotypes will blush with lavender tinges, although purple is not a dominant trait across the line. Trichome coverage is a standout, frequently giving the buds a frosted, almost sugared appearance by week 7. Under magnification, heads often appear large and well-formed, an attribute valued for both solventless and hydrocarbon extraction. This resin density contributes to strong aroma projection even in jars.

Structure typically holds up well to handling and transport, which reduces bag appeal loss from bud crumble. With proper drying and curing, the flowers retain a slightly tacky feel for weeks, indicating appropriate water activity and terpene preservation. Consumers often note that the first impression is bright and citrus-forward, quickly followed by deeper earthy or hashy accents on the break. That layered complexity makes 3DG13 both eye-catching and intriguing on the nose.

Aroma and Terpene-Driven Bouquet

Aromatically, 3DG13 tends to open with a striking citrus and tropical top note inherited from the 3D side. Common descriptors include pineapple, sweet grapefruit, lemon zest, and a faint herbal-cleaner twist characteristic of terpinolene-rich cultivars. Upon grinding, secondary layers of cedar, damp earth, and peppery spice emerge, reflecting G13’s Afghani roots and beta-caryophyllene influence. This duality gives the nose both sparkle and depth.

The bouquet evolves over time as the jar breathes, often showing a candy-like sweetness after the first minute of exposure to air. Some cuts introduce subtle honeysuckle or green mango, hinting at ocimene or a floral linalool trace. If the finish leans more G13, an incensey, hash-forward undertone may anchor the aroma with a slightly musky base. These base notes can intensify in late cure, especially beyond the 21–28 day mark.

Environmental conditions strongly shape the aromatic outcome. Warmer, drier rooms during late flower tend to emphasize lemon-peel sharpness and cleaner-like terpinolene aspects. Cooler rooms with balanced RH can accentuate sweet tropical facets and preserve delicate monoterpenes. Growers who dry at 60°F/60% RH for 10–14 days often report the richest terpene retention and most nuanced bouquet in the jar.

Flavor Profile and Combustion Characteristics

On the palate, 3DG13 usually begins with bright citrus and sweet tropical flavors reminiscent of pineapple and grapefruit. The mid-palate transitions to pine, cedar, and faint herbal tea, with a peppery tickle on the exhale when beta-caryophyllene is prominent. In some phenotypes, the finish carries a soft, creamy sweetness that rounds the edges and reduces perceived harshness. The overall flavor arc is layered, moving from sparkle to woodsy depth in a single draw.

Combustion quality is strongly correlated with cure and mineral balance, but well-grown 3DG13 is typically smooth and aromatic. Dry pulls often reveal a candied-lemon rind and herbal-cleaner note from terpinolene before the spark hits. When vaporized at 350–380°F, sweet-citrus and floral top notes shine, while higher temps above 400°F unlock deeper hash, clove, and woody resin. Many users prefer a stepped temperature approach in vaporizers to experience the full bouquet.

Residual flavors after the session linger as citrus peel and gentle spice, making 3DG13 a pleasant pairing with black tea, sparkling water, or light cheeses. Because the terpene mix can be volatile, airtight storage and proper humidity control are essential to keep flavors intact. In blinded tastings, panels often describe 3DG13 as “zesty, pine-bright, and resin-backed,” consistent with expectations for a 3D × G13 hybrid. The complexity is a major reason it appeals to experienced consumers who prioritize flavor evolution.

Cannabinoid Profile and Potency Metrics

3DG13 expresses as a THC-dominant chemotype with low inherent CBD, consistent with both parental lines. For most well-grown batches, expect 19–24% THC by dry weight, with occasional outliers that can dip to 16–18% under suboptimal conditions or reach 25–26% under elite cultivation. CBD generally sits below 1%, often in the 0.1–0.6% range, while total minor cannabinoids like CBG and CBC typically contribute 0.3–1.5% combined. Total terpene content commonly lands between 1.5% and 2.5%, influencing perceived potency via entourage effects.

Potency perception is not dictated by THC alone. Studies suggest that terpene load, especially terpinolene, limonene, and beta-caryophyllene, can modulate subjective intensity and the qualitative nature of the high. Users often report a rapid onset within 2–5 minutes when inhaled, a 30–60 minute peak, and a 2–3 hour taper. In edible formats, onset may take 45–120 minutes with a 4–6 hour duration, depending on dose and individual metabolism.

From a dosing perspective, inhaled servings of 5–10 mg THC equivalent are common for intermediate users, while sensitive individuals often find 1–2 mg sufficient. For edibles, first-time or low-tolerance users should start with 2–2.5 mg THC, waiting a full 2 hours before considering a redose. The presence of limonene and terpinolene may increase the perception of brightness and energy at lower doses, while the G13 base asserts more body relaxation as dosage increases. These dynamics underscore the value of titration and mindful session planning.

Terpene Profile and Minor Volatile Compounds

The dominant terpene spectrum for 3DG13 often centers on terpinolene, limonene, myrcene, and beta-caryophyllene. In lineage-consistent phenotypes, terpinolene commonly falls around 0.3–0.8% by dry weight, while limonene ranges 0.2–0.6%. Myrcene may present at 0.3–0.9%, imparting tropical depth and a mild sedative undertone, and beta-caryophyllene often lands near 0.2–0.5%, adding peppery spice and potential CB2 receptor activity. Secondary contributions can include ocimene (0.05–0.2%), linalool (0.05–0.15%), and humulene (0.1–0.3%).

This terpene mix explains the layered sensory experience. Terpinolene is associated with fresh, citrus-cleaner aromatics and a mentally lifting first impression. Limonene bolsters lemon and grapefruit brightness and is frequently linked to elevated mood in user reports. Myrcene and humulene round the base with earthy, resinous, and gently herbal tones, while beta-caryophyllene adds spice and a warm, woody backbone.

Minor volatiles such as aldehydes, esters, and thiols can contribute meaningful nuance. Trace esters may produce pineapple candy notes, especially when drying temperatures are well controlled. A faint sulfuric or skunky edge can appear in some phenos if volatile thiols are present, though 3DG13 is generally less skunk-dominant than classic Chem or Skunk lines. Post-harvest handling has an outsized impact on preserving these fragile compounds.

Experiential Effects and Onset Timeline

3DG13 often delivers a two-stage experience that begins with clear-headed uplift and sensory brightness. Within minutes of inhalation, users report a gentle rise in focus and mood, reflecting the terpinolene-limonene top end. As the session progresses, the G13 base provides grounding, with body heaviness and tension release becoming more pronounced. The result is a balanced hybrid arc that suits late afternoon through evening use for many people.

Onset is relatively fast with smoked or vaporized routes, usually 2–5 minutes to noticeable effects. Peak intensity tends to occur around 30–60 minutes, with a comedown that gradually softens over 2–3 hours. The mental component is described as buoyant but not racy at moderate doses, though sensitive users should monitor for jitters if they are highly reactive to terpinolene-dominant profiles. The body feel ranges from light warmth to deeply relaxing heaviness depending on dose and phenotype.

Reported side effects are typical of THC-rich cannabis. Dry mouth is common, affecting an estimated 30–60% of users, and dry eyes are reported by 15–25%. Rarely, high doses can provoke transient anxiety or palpitations in sensitive individuals, particularly with fast inhalation stacking. Hydration, paced dosing, and calm settings mitigate most issues.

Functionally, many users find 3DG13 suitable for creative tasks, light socialization, and decompression. The hybrid balance supports a transition from daytime activity to evening relaxation without immediate couchlock at conservative doses. At higher doses or toward the tail end of the effect curve, sedation can increase, aligning the strain well with late-night wind-down. Music, cooking, and outdoor strolls pair especially well with its sensory profile.

Potential Medical Applications and Evidence Base

While specific clinical trials on 3DG13 do not exist, its cannabinoid-terpene architecture aligns with use-cases common to THC-dominant hybrids. The National Academies 2017 review found substantial evidence that cannabis is effective for chronic pain in adults and conclusive evidence for chemotherapy-induced nausea and vomiting when paired with conventional antiemetics. THC itself has robust analgesic and antiemetic properties, while beta-caryophyllene’s CB2 activity has been investigated for inflammation modulation. Limonene and linalool are frequently cited in preclinical literature for anxiolytic and mood-related effects, though human evidence remains limited.

For patients with neuropathic or musculoskeletal pain, a THC-dominant hybrid like 3DG13 may be useful during late-day flare-ups. The early mental lift can support mood, while the G13 undercarriage provides somatic relief and muscle relaxation. Doses in the 2–5 mg THC range may be adequate for low-tolerance individuals, with 5–10 mg for intermediate users and careful titration upward as needed. Combining inhaled microdoses with small oral doses can extend coverage while minimizing peaks.

Sleep disturbance is another area where this profile can help, especially when doses are taken 60–90 minutes before bed. Moderate evidence suggests short-term improvements in sleep onset for THC-containing products, though tolerance can develop with nightly use. Patients often report that 3DG13’s arc facilitates a graceful slide from post-work decompression into sleep when timing and dose are tuned. Keeping a journal of dose, timing, and sleep metrics can help optimize routines.

Patients dealing with appetite loss may also benefit from THC-forward cultivars. Cannabis has long been associated with increased caloric intake, and THC’s orexigenic effects are well documented. Limonene’s bright aroma may improve anticipatory appetite by sensory priming. As always, clinicians recommend caution for individuals with cardiometabolic concerns when using high-calorie snacks alongside cannabis.

This information is educational and not medical advice. Patients should consult healthcare professionals familiar with cannabinoid medicine, especially if taking medications that interact with CYP450 pathways. Start low, go slow, and adjust only after assessing response over multiple sessions. Individual variability is substantial, and what works well for one person may not translate to another.
