G13 x Haze is a mostly sativa cultivar bred by Scott Family Farms, engineered to marry the cerebral electricity of the Haze family with the grounding potency historically associated with G13. Growers and consumers often seek this cross for daytime focus, elevated mood, and a persistent, resin-heavy finish that signals serious potency. While exact sativa-to-indica ratios can vary by cut, it consistently leans sativa in structure, effect, and flowering behavior.
Fans of classic Haze will recognize the lineage in its citrus-forward lift, while the G13 side contributes body presence and depth of flavor. The combination creates a versatile profile that can power creative sessions while keeping fatigue and low motivation at bay. Its reputation for bright, euphoric energy aligns closely with published descriptions of Haze’s effect profile while adding a touch more body weight and calm.
From a market standpoint, G13 x Haze competes in the same lane as cup-winning Haze hybrids that emphasize high THC potential and terpinolene-led aromatics. Notably, Leafly documents that the Haze family tends to deliver energetic, creative, and uplifted effects, with some users reporting anxiety or dizziness at high doses. This cross was built to preserve that sunny, creative lane while lending a steadier landing courtesy of G13’s stocky cannabinoid backbone.
History and Breeding Story
The origin story of G13 is steeped in myth, often associated with clandestine breeding programs and foundational Afghani genetics. Regardless of legend, what’s consistent is G13’s reputation as a potent indica-leaning line that passes on dense trichome production and an earthy, pine-forward aroma. By contrast, Haze traces back to the Haze Brothers on the West Coast and represents a blend of tropical sativas, historically linked to Colombian, Thai, and South Indian inputs.
Scott Family Farms’ G13 x Haze follows a long tradition of pairing deep indica bases with high-vigor sativas to achieve modern performance. The breeder’s remit with this cross appears clear: stabilize a sativa-dominant effect curve while maintaining yield, resin output, and a terpene package that stands out in a crowded market. Sativa structure and flowering time remain, but the G13 driver improves density and bag appeal.
The broader context helps make sense of this pairing. Leafly highlights Haze for its sweet citrus, floral notes, and euphoric energy, a sensory profile breeders frequently chase when designing daytime cultivars. The success of related G13 x Haze derivatives, including Liberty Haze (G13 x Chemdawg) winning the 2011 High Times Cannabis Cup, underscores how potent and commercially viable this genetic axis can be when executed well.
Genetic Lineage and Heritage
Lineage analysis places G13 x Haze at the crossroads of heavy resin Afghani influence and the bright, terpinolene-rich Haze family. From G13, expect a stout trichome engine and a base note of earthy, pine, and faint spice. From Haze, anticipate elongated internodes, loud citrus-floral top notes, and the characteristic energetic tempo that built the family’s reputation.
Haze’s chemical fingerprint frequently leans terpinolene-dominant, and Leafly’s coverage of the Haze family reinforces the citrus-floral bouquet with a euphoric, creative push. That chemistry sets the tone for headspace and mood, especially when THC is medium-high or high. G13 tends to layer in myrcene and alpha-pinene, as indicated by related G13 descendants like ‘88 G13 Hashplant, where lab summaries commonly list myrcene followed by pinene.
Together, the cross results in a balanced-but-bright chemovar that feels distinctly sativa while avoiding the extreme narrow structure and ultra-long bloom that pure Hazes can exhibit. Many growers find it more cooperative than a classic Haze, yet more stimulating than a pure G13 phenotype. The net result is a sativa-forward hybrid with a reliable cannabinoid payload and a terpene stack anchored by terpinolene, limonene, myrcene, and alpha-pinene.
Morphology and Bag Appeal (Appearance)
G13 x Haze generally grows with sativa-dominant structure, showing taller vertical growth and longer internodal spacing. Expect 1.5x to 2.0x stretch after the flip to 12/12, consistent with Haze-heavy plants that surge during early bloom. Stems are moderately thick, and the canopy benefits from training to manage verticality and improve light penetration.
Flower formation tends toward spearlike colas with a good calyx-to-leaf ratio, making hand-trimming efficient. Buds often show lime to forest green hues with neon-orange pistils woven through dense frost. The G13 side helps compact the flowers compared to stringier pure Hazes, increasing apparent density and weight per node.
Under strong light, trichome coverage is notable and tends to be one of the cultivar’s calling cards. Expect a “sugar crust” appearance on the outer calyces, with milky heads late in bloom and amber showing progressively from the top-down. The finished bag appeal recalls cup-winning Haze hybrids like Liberty Haze, which Leafly notes as bright green and frosty—an aesthetic that translates here through the G13 contribution.
Aroma and Bouquet
The nose on G13 x Haze is vivid and layered. Top notes typically deliver sweet citrus—think lemon zest with hints of orange peel—followed by a fresh, floral lift that Leafly associates with the Haze family. Beneath the brightness, the G13 side contributes earthy pine, a faint herbal bitterness, and a peppery spice that reads clean and classic.
When you break a bud, the bouquet expands. Terpinolene-driven citrus blooms first, then limonene’s zesty snap, followed by a cool pine needle impression from alpha-pinene. A low hum of myrcene provides the connective tissue, making the aroma feel rounder and slightly musky as the volatiles aerate.
In jars, the scent evolves as moisture equilibrates and monoterpenes volatilize slowly. Early-curing jars smell candied and floral; around week three to four, the pine-earth spine steps forward and the citrus becomes more integrated. The end result is a Haze-forward perfume with enough depth to satisfy old-school palates who want substance beneath the sparkle.
Flavor and Combustion Characteristics
On the palate, G13 x Haze hits first with a sweet-tart citrus that matches the smell—lemon-lime candy with a delicate blossom note. The mid-palate introduces fir needle and cracked pepper, bridging into a gentle herbal bitterness reminiscent of green tea. Exhale leaves a lingering citrus rind and a dry, piney echo that cleanses rather than cloys.
Vaporization temperatures influence what you taste. At 175–185°C, citrus and floral compounds dominate, spotlighting terpinolene and limonene. Pushing into 190–205°C unlocks woodsy pinene notes and a fuller body feel, though you’ll sacrifice some top-end brightness as monoterpenes flash off faster.
Combustion is typically smooth when properly cured. White to light-gray ash and a clean burn line indicate good post-harvest handling, preserving terpene nuance for two to four weeks of peak flavor. Over-drying below roughly 10% moisture content can dull the citrus and skew the profile toward spice and earth, so careful curing is essential.
Cannabinoid Profile and Potency
While specific lab results vary by cut and cultivation, G13 x Haze generally slots into the high-THC sativa category. Expect total THC commonly in the 18–26% range when grown under optimized conditions, with standout phenotypes capable of pushing higher. CBD is typically low, often ≤1%, while CBG may register between 0.2–1.0% in mature flowers.
This potency bracket aligns with documented Haze-line performers. For context, related Haze hybrids have long been known for high THC expression, and Leafly’s coverage of Haze describes a spectrum from low THC to high THC with strong energetic effects. Additionally, notable G13-influenced cultivars such as Liberty Haze have demonstrated competition-caliber potency, winning the 2011 High Times Cannabis Cup and anchoring the genetic reputation for power.
Users can expect a rapid onset with inhalation—often within 2–5 minutes—peaking around the 30–60 minute mark and tapering over 2–3 hours. Edible or tincture preparations based on this chemovar will extend the timeline substantially, with onset at 45–120 minutes and total duration 4–8 hours depending on dose and metabolism. Because of its sativa tilt and THC-forward profile, careful titration is advised for newer consumers to avoid anxious edges.
Terpene Profile and Chemistry
Chemically, G13 x Haze expresses a terpene ensemble consistent with Haze-forward plants. Terpinolene commonly leads, delivering sweet citrus, floral, and a crisp herbal lift that Leafly identifies across the Haze family. Limonene follows with bright lemon-orange accents and perceived mood elevation, while myrcene provides musk and body.
Alpha-pinene frequently appears as a notable secondary or tertiary terpene, contributing coniferous freshness and a sense of mental clarity. In related G13-descended lines like ‘88 G13 Hashplant, lab notes often place myrcene first with pinene following, a pattern that can echo here depending on phenotype. Trace contributions of ocimene, linalool, and farnesene are not unusual, adding green, floral, and apple-skin nuances, respectively.
Total terpene content for well-grown Haze-centric flowers typically ranges from 1.5–3.5% by dry weight, with elite batches exceeding 4.0%. Terpinolene-dominant cultivars are common among high-aroma releases; Leafly’s reporting on terpinolene-forward strains such as Candy Games #24 and numerous Haze descendants highlights lemon-candy, floral, and gas-adjacent notes that parallel what many find in G13 x Haze. Aroma intensity is further shaped by curing parameters, storage temperature, and light exposure, which can degrade monoterpenes faster than sesquiterpenes if mishandled.
Experiential Effects and Use Cases
Expect an uplifting and creative headspace that arrives quickly and encourages movement, brainstorming, or socializing. Leafly’s profile of Haze emphasizes energetic, creative, and uplifted experiences, and those traits translate here with high fidelity. The G13 component adds a mild somatic steadiness that keeps the mental buzz from feeling overly jittery.
At moderate doses, users often report enhanced sensory acuity, task focus, and a curious, exploratory mindset. Music, design work, and outdoor activities pair especially well, as the cultivar promotes a clean mental runway without heavy sedation. At higher doses, the intensity can tip into racing thoughts for some, echoing Haze’s known potential for anxious or dizzy moments in sensitive users.
Physically, the body feel is present but secondary. There’s enough muscle comfort and joint ease to notice—particularly 30–45 minutes after onset—without blunting alertness. The come-down is gentle, leaving most users functional and clear rather than groggy, a hallmark of sativa-leaning daytime plants.
Potential Medical Applications
For medical consumers, the sativa-forward energy and bright mood lift may assist with daytime fatigue, low motivation, and situational depressive symptoms. Terpenes like limonene have been studied for potential anxiolytic and mood-elevating properties in preclinical settings, and alpha-pinene is associated with alertness and possible bronchodilatory effects. These traits, combined with THC-mediated euphoria, can support engagement with physical therapy, chores, or creative tasks.
Analgesic potential is moderate, with users commonly reporting tension relief, reduced headache pressure, and mild peripheral pain mitigation. Myrcene’s presence may contribute to this comfort, as it is frequently associated with body relaxation and analgesia in cannabis chemovars. Those seeking strong neuropathic pain relief or sleep support may prefer evening strains with higher myrcene and linalool, but G13 x Haze can serve as a daytime option that eases discomfort without sedation.
Because classic Haze lines can provoke anxiety or paranoia at high doses, patients with panic disorder or PTSD should start low and go slow. Vaporization at lower temperatures and microdosing strategies can capture the cognitive lift while minimizing edge. As with any cannabis therapy, medical users should consult clinicians, track responses, and consider balanced formulations if THC sensitivity is high.
Comprehensive Cultivation Guide
G13 x Haze grows most happily in environments that celebrate sativa vigor while imposing canopy discipline. Indoors, a SCROG or light trellis is strongly recommended to manage 1.5–2.0x stretch, maintain even tops, and optimize light distribution. Outdoors, full sun and ample root space unlock vertical potential, but support stakes are advisable heading into late flower.
Vegging parameters: keep temperatures at 24–28°C during the day and 18–22°C at night, with relative humidity at 60–70%. Aim for a VPD of 0.8–1.2 kPa in veg, a pH of 5.8–6.2 for hydro or 6.2–6.8 for soil, and medium EC around 1.4–1.8 mS/cm. Provide a DLI of 35–45 and PPFD of 600–900 µmol/m²/s, increasing gradually to avoid stress.
Flowering spans roughly 10–13 weeks depending on phenotype and environment, with Hazier expressions trending longer. Early flower benefits from RH at 50–55% and VPD 1.1–1.3 kPa; mid-late flower should tighten to 45–50% RH and 1.3–1.6 kPa VPD to combat botrytis risk. Day temps of 24–27°C and cooler nights of 17–20°C help preserve terpenes while encouraging color expression in some cuts.
Nutrient strategy should start nitrogen-forward in veg, then pivot to phosphorus and potassium from week 3 of bloom onward. Peak EC typically lands between 1.8–2.2 mS/cm in coco or hydro if plants are thriving, though soil growers should observe leaf color and runoff EC to avoid salt buildup. Cal-mag supplementation is helpful under high-intensity LEDs due to increased transpiration.
Training and pruning: top once or twice in veg, then employ LST and netting to build a wide, even canopy. Light defoliation around weeks 3–4 of flower improves airflow without shocking sativa phenotypes that depend on their solar panels. Avoid heavy leaf stripping late in bloom, as Hazier plants can stall if over-stressed.
Lighting and CO2: under high-efficiency LEDs, target 900–1200 µmol/m²/s of PPFD in bloom, increasing CO2 to 1,000–1,200 ppm to maintain photosynthetic headroom. Keep leaf surface temperature in check; sativas can handle intensity, but tip burn and foxtailing will surface if heat and feed run out of balance. Incremental ramping prevents terpene washout and preserves resin density.
Irrigation: in coco, frequent small irrigations maintain ideal root-zone oxygen. In soil, allow moderate dry-backs to support robust root growth while avoiding hydrophobic pockets. Aim for 10–20% runoff in soilless systems to manage EC, and monitor weight-based pot metrics to time feeds accurately.
Pest and disease management should prioritize airflow and cleanliness. Haze-dominant canopies are susceptible to powdery mildew if RH and leaf stacking get away from you; keep canopy thin, run oscillating fans, and maintain good intake filtration. For IPM, deploy beneficials early for mites and thrips, and avoid late-flower sprays to protect resin and flavor.
Yield expectations vary by cut and technique. Indoors, 450–650 g/m² is attainable with dialed SCROG and high PPFD; outdoors, 600–900 g per plant is reasonable in warm, dry climates with long seasons. The plants reward precision, and small environmental improvements often return outsized gains in clarity of effect and terpene richness.
Harvest, Curing, and Post-Processing
Harvest timing is critical for shaping the headspace. For a brighter, racier effect, harvest when trichomes are mostly milky with minimal amber—often the first week the cultivar looks “finished.” For a rounder, slightly calmer profile, wait until 10–15% amber appears, typically 5–10 days later depending on conditions.
Dry slowly at 18–20°C and 55–60% RH for 10–14 days until stems snap cleanly rather than bend. This pace preserves monoterpenes like terpinolene and limonene that drive the citrus-floral signature. Faster, hotter dries can flatten flavor and push the strain toward generic pepper-earth.
Curing proceeds best in airtight containers filled to 60–70% with properly dried flower, aiming for a target water activity of 0.55–0.65 aw. Burp jars daily for the first week, then every 2–3 days for the next two to three weeks, allowing CO2 and volatile acids to dissipate. Most phenotypes show peak aroma between weeks 3–5 of cure, with citrus and floral notes integrating over time into a polished pine-citrus chord.
Comparisons to Related Strains
Compared to a pure Haze, G13 x Haze is more approachable in both structure and body feel. It retains the classic Haze citrus-floral and euphoric energy that Leafly emphasizes, yet lands more gently due to G13’s grounding influence. Flowering time is typically shorter than vintage Hazes and density is higher, improving trim yield and bag appeal.
Against Liberty Haze (G13 x Chemdawg), the flavor diverges; Liberty often leans lime-diesel with sharper chem edges, as documented by Leafly’s coverage of the 2011 Cup winner. G13 x Haze trends more floral and pine, with a smoother sweetness and less gas. The effect profiles overlap in daytime viability, but G13 x Haze can feel airier and more sparkling up top.
Relative to Super G (G13 x Super Silver Haze), which Leafly calls a Haze-heavy powerplayer, G13 x Haze usually reads as slightly less metallic and incense-like. Super Silver Haze heritage can push incense, spice, and a racy top speed, while G13 x Haze settles into a citrus-bloom lane with cleaner pine. Both satisfy sativa seekers; the choice comes down to whether one prefers more incense-gas or citrus-floral-pine.
Evidence From The Haze Family and G13 Descendants
Multiple Leafly sources contextualize the sensory and experiential expectations for this cross. Leafly’s Haze page emphasizes energetic, creative, and uplifted effects, with some users noting paranoia, anxiety, or dizziness when overconsumed. That aligns with the bright, terpinolene-limonene engine commonly found in Haze-family chemovars.
A Leafly feature on Haze terpenes highlights sweet citrus flavors with a compelling floral note that leads into euphoric, uplifting energy. Those descriptors map directly onto the top end of G13 x Haze’s aroma and onset, making Haze’s role in the cross unambiguous. By contrast, Leafly’s write-up on ‘88 G13 Hashplant lists myrcene and pinene, demonstrating how G13-leaning lines contribute earth, musk, and pine—traits that add ballast here.
Further, Leafly notes Liberty Haze—a G13 cross—as the 2011 High Times Cannabis Cup winner, underscoring how this genetic stream produces award-grade potency and bag appeal. Leafly’s New Strains Alert featuring Super G (G13 x Super Silver Haze) reinforces the market appetite for Haze-driven sativas anchored by G13’s power. Together, these references illustrate why Scott Family Farms’ G13 x Haze can credibly deliver high-aroma, high-energy performance with a polished finish.
Responsible Use, Tolerance, and Dosing Considerations
Because THC commonly resides in the 18–26% range for this line, newcomers should begin with one or two small inhalations and wait 10–15 minutes before re-dosing. Sensitive users can favor low-temperature vaporization to capture citrus-floral lift while minimizing intensity. Seasoned consumers can titrate to effect, but stacking large doses quickly can evoke the Haze family’s anxious ceiling noted on Leafly.
Edible applications demand patience. Start with 1–2.5 mg THC, increase only after 24 hours of evaluation, and pair with balanced cannabinoids if available. A small CBD chaser can modulate the experience for some, though results vary person to person.
Hydration, nutrition, and set-and-setting also influence outcomes. Light snacks and water help stabilize blood sugar and comfort during a peaky sativa arc. Choose contexts that reward creativity and movement, and avoid stressful environments during first trials with a new, potent sativa hybrid.
Sourcing, Phenohunting, and Selection Tips
Phenohunting G13 x Haze benefits from clear selection goals. If flavor is paramount, hunt for terpinolene-dominant expressions that shout citrus and blossom when you rub the stems in veg. If yield and structure lead, prioritize plants with tighter internodes, thicker laterals, and naturally denser flower clusters.
During flower, inspect resin coverage under magnification. Look for early trichome density by week 4–5 of bloom and uniform frosting across bracts. Keep notes on aroma evolution from week to week, as top-performing phenotypes often show a layered bouquet even before full maturity.
Post-harvest, compare batches after a standardized cure of at least three weeks. Sensory panels of 3–5 tasters can rate aroma intensity, flavor fidelity to the nose, harshness, and effect clarity on a 1–10 scale. Consistent 8+ ratings on aroma and flavor with a clean, clear effect arc signal keeper status in a sativa-forward program.
Market Position and Consumer Profile
G13 x Haze sits squarely in the high-energy sativa shelf segment alongside proven Haze hybrids. Its selling points include bright citrus-floral aroma, frosty visual appeal, and functional daytime effects that many professionals, artists, and outdoor enthusiasts prefer. For retailers, it can anchor a terpene-forward category and provide an alternative to gas-heavy or dessert-forward trends.
Consumer profiles that gravitate to this strain tend to value cognition, motivation, and flavor clarity. Those who love classic Haze but want denser buds and a smoother landing will find this cross hits the brief. Medical buyers looking for daytime relief from fatigue or low mood may also connect with its chemistry.
Competitive positioning leverages the verified Haze narrative and the proven power of G13 offspring. Leafly’s top-100 strain collections historically include Haze-line legends, demonstrating sustained cultural capital around this effect space. A clean brand story—“sativa clarity with G13 backbone”—communicates quickly on menus and in budtender scripts.
Common Pitfalls and How to Avoid Them (Growers)
Over-vegetation is the first trap. With 1.5–2.0x stretch incoming, flipping too late produces canopies that outgrow vertical clearance and compromise light uniformity. Start training early, flatten the canopy, and flip once you’ve filled 60–70% of the screen.
The second pitfall is humidity mismanagement in mid-late bloom. Haze-leaning plants build long, chunky colas that are gorgeous but vulnerable to botrytis if RH stays above ~55% late. Increase airflow, defoliate conservatively for lung space, and target 45–50% RH from week 6 onward.
Lastly, watch the feed as intensity rises. High PPFD without proportional CO2, temperature, and nutrient support leads to tip burn and terpene wash. Ramp light and EC methodically, monitor runoff EC and pH, and consider backing off 10–15% on feed strength during the final two weeks to sharpen flavor.
Data Benchmarks and Reasonable Expectations
Potency targets of 18–26% THC are realistic with modern LED rooms, optimized VPD, and dialed nutrition. Total terpene content of 1.5–3.5% by weight is a fair benchmark, with terpinolene commonly registering as a lead terpene and limonene, myrcene, and alpha-pinene rounding out the stack. Indoor yields of 450–650 g/m² are achievable under 900–1200 µmol/m²/s PPFD and CO2 around 1,000–1,200 ppm.
Time-to-harvest typically lands between 70–90 days of bloom, depending on phenotype and desired effect. Drying for 10–14 days at 18–20°C and 55–60% RH protects monoterpenes, with a 3–5 week cure bringing the nose to full expression. Expect a shelf life of 4–6 months at cool, dark storage if humidity is maintained around 55–62% and oxygen exposure is minimized.
For consumers, onset within 2–5 minutes by inhalation and a 2–3 hour overall experience is typical. The first 45–60 minutes are the most cognitively active, ideal for work sprints or outdoor activity. Parity with Leafly’s Haze descriptors—energetic, creative, uplifted—makes these expectations reliable across many cuts of G13 x Haze.
Final Thoughts
G13 x Haze from Scott Family Farms captures the timeless appeal of Haze—the citrus-floral lift, the sparkling creativity—and tempers it with G13’s resin density and steadier physical base.
