New Caledonia #4 Haze traces its roots to Maha Kala Seeds, a boutique breeder known for curating landrace influences and long-flowering sativa expressions. The “#4” tag signals a selected phenotype from a New Caledonian line that displayed standout vigor, resin character, and an unmistakably electric, tropical Haze personality. While breeder notes are intentionally sparse, community consensus points to a careful integration of a New Caledonia landrace selection with a Haze-leaning parent to stabilize height, aroma, and the soaring sativa effect. The result is a cultivar that pays tribute to classic Haze architecture while showcasing island-born terpenes and resilience.
Historically, Haze-leaning strains draw from a composite of Colombian, Thai, and Mexican sativa heritage, consolidated in California breeding circles in the 1970s. Maha Kala Seeds’ approach fits that lineage, prioritizing expressive phenotypes over quick flowering or heavy indica densification. The “New Caledonia” component nods to Pacific island landrace influence, which typically expresses in elongated internodes, spicy-citrus aroma, and an active, lucid headspace. In this context, New Caledonia #4 Haze positions itself as a modern heir to a storied genetic tradition.
Bred by Maha Kala Seeds, the strain retains a distinctly sativa heritage and is marketed to experienced growers and connoisseurs who appreciate long-cycle cultivars. Landrace-forward sativas often require precise environmental control, which matches the brand’s emphasis on skillful cultivation and phenotype hunting. In practical terms, this means growers can expect notable stretch, relatively airy yet high-surface-area flower clusters, and terpene profiles that intensify late in bloom. As with many Hazes, patience and canopy management are rewarded with exceptional aromatics and a cerebral, enduring effect.
Commercially, New Caledonia #4 Haze occupies a niche: it is not a mass-market quick finisher, but rather a specialty cultivar. Many producers report that sativa-variety crops represent a smaller share of industrial output due to longer flowering windows and lower grams-per-square-foot throughput compared to compact indicas. Yet demand for distinctive, high-terpene sativas remains strong in enthusiast markets, where unique provenance and complexity can command premium prices. That makes this strain compelling for craft producers targeting terpene-forward, differentiated offerings.
For cultural context, the interest in Pacific landrace lines has grown as consumers seek both novelty and authenticity. New Caledonia #4 Haze leverages that demand, providing a genetic story backed by a breeder known for sativa-forward selections. The cultivar’s reputation has been built largely by word-of-mouth, grow logs, and lab panels from analogous Haze lines, reinforcing its status as a connoisseur sativa. In short, it stands at the crossroads of heritage and modern craft expectations, aligning with informed growers and adventurous consumers.
Genetic Lineage and Haze Heritage
The working narrative places New Caledonia #4 Haze within a Haze-centric family tree, with the New Caledonian selection contributing tropical, citrus-floral notes and pronounced cerebral lift. Classic Haze lineage typically synthesizes traits from Colombian Gold, Thai sativas, and Mexican lines, and these influences present in the plant’s morphology and effect profile. The “#4” selection indicates that the breeder identified a specific phenotype that balanced vigor with aromatics, implying a curated, multi-plant selection process. This practice is common among sativa breeders who must dial in internode lengths, stretch, and flower set across long cycles.
Phenotypically, growers should anticipate a narrow-leaf sativa structure with long petioles, pliable branches, and an open, speary bud formation. Such morphology is consistent with equatorial-adapted cannabis, which has evolved for high light intensity and airflow, reducing the risk of bud rot in humid climates. The Haze component likely intensifies resin head density and lengthens the flowering window, which can run longer than mid-latitude hybrids. Together, these traits produce a plant that responds well to trellising and Screen of Green (ScrOG) methods.
Chemically, the Haze heritage drives terpene patterns often dominated by terpinolene, ocimene, and pinene, supported by citrus-spice accents from limonene and caryophyllene. New Caledonian influences may amplify tropical fruit volatiles and a brisk, minty-pine top note. Reports from growers of comparable Maha Kala lines suggest total terpene content can reach 1.8–3.2% by dry weight under optimal conditions. This aligns with published ranges for terpene-rich sativas, where 1.5–3.0% is common in craft-grade material.
The cultivar’s chemotype is predicted to be THC-dominant with very low CBD, reflecting a typical Haze profile. Many Haze-leaning sativas test between 16–24% THC, with occasional outliers above 25% in dialed-in grows. While specific lab series for this exact cut remain limited in the public domain, the pattern across similar Maha Kala sativas supports a potency window in that range. As always, environment, harvest timing, and cure practices can shift variance by several percentage points.
Genetic stability in long-cycle sativas can be challenging due to the polyhybrid nature of Haze lines and the complexity of landrace contributions. The #4 selection suggests targeted stabilization for desirable traits, though minor phenotype variance should still be expected. Tactical cloning from a vetted mother is recommended to lock in consistency for commercial runs. For seed runs, rigorous phenohunting across 6–12 plants typically yields at least one keeper that matches the intended profile.
Visual Traits and Bud Structure
New Caledonia #4 Haze presents an elegant, classic sativa silhouette with narrow, serrated leaves and a high node count. Expect plants to stretch 150–250% after the flip indoors, reaching 120–180 cm in standard tents and significantly taller in open rooms if not managed. The branching habit is lateral but flexible, making the cultivar responsive to low-stress training and multi-point trellising. Stems are moderately lignified by mid-bloom, but the canopy remains pliable enough for ongoing tuck-and-weave techniques.
Bud development favors long, tapering colas composed of stacked, foxtailing calyces rather than dense, golf-ball nuggets. This architecture improves airflow through the inflorescence, a boon in humid climates or dense canopy layouts. The surface area-to-mass ratio is high, supporting deep terpene expression and even drying. Trichome coverage is conspicuous along calyx tips and sugar leaves, giving the flowers a shimmering, frosted sheen under direct light.
Coloration trends toward lime and forest green, sometimes with subtle golden pistils that darken to amber with maturity. Cooler night temperatures in late bloom can tease out faint lavender hues in some phenotypes, though pronounced anthocyanin displays are uncommon. Resin heads typically display a high proportion of cloudy trichomes by peak harvest with a slower transition to amber compared to indica-leaning cultivars. This slower ambering is consistent with long-flowering sativas and can aid in precise harvest targeting.
Average internode spacing runs medium-long, a hallmark of equatorial genetics that thrive under high-intensity light. Outdoor plants, given a long season, can develop central leaders that exceed 2.5 meters, creating a striking spear-shaped crown. Indoors, a purposeful topping and ScrOG approach can redistribute growth, creating 8–20 productive sites per plant depending on pot size and veg duration. This structure is instrumental for maximizing even light distribution and yield per square meter.
Trim quality is typically high once fan leaves are removed, as sugar leaves are slender and close to the calyxes. Machine trimming is possible with careful settings, but hand trimming preserves the conical calyx architecture best. The final bag appeal leans toward artisanal sativa elegance rather than brute density, an aesthetic appreciated in connoisseur markets. Proper cure accentuates the crystalline resin mantle and helps prevent over-drying of the fine floral structures.
Aroma Spectrum and Volatile Chemistry
On the nose, New Caledonia #4 Haze broadcasts a vibrant bouquet of tropical citrus, green mango, and passionfruit, wrapped in piney sparkle and white pepper. As the jar breathes, secondary notes reveal lemongrass, eucalyptus, and a subtle floral incense reminiscent of classic cathedral Haze. The profile is high-key and complex, with a top note likely driven by terpinolene and ocimene, and a grounding base of caryophyllene and humulene. In well-cured samples, a clean, minty-camphor twist can appear, hinting at alpha-pinene and borneol-like components.
Volatile chemistry in Haze-leaning sativas often skews toward monoterpenes that evaporate quickly, which explains the exhilarating, head-clearing first impression. Terpinolene, which frequently dominates Hazes, has been documented in cannabis at proportions exceeding 30% of the terpene fraction in some chemovars. Ocimene blends sweet-tropical tones with a green, herbaceous lift, while limonene provides lemon-zest brightness. Beta-caryophyllene adds a peppered warmth capable of anchoring the bouquet without dampening its sparkle.
The aroma evolves with handling and grind, releasing secondary esters and sulfurous trace volatiles that contribute to perceived intensity. Freshly broken buds tend to show brighter citrus and sweet fruit, while ground material reveals pine resin and pepper. During combustion, incense and spice tones rise to prominence, giving a nostalgic nod to 1970s Haze. The dynamic character—fruity to piney to spicy—reinforces the cultivar’s complex biochemical ensemble.
Environmental control during dry and cure is crucial to preserving these volatile compounds. Studies indicate monoterpene losses can exceed 30% with fast, warm drying, particularly above 22°C and at RH below 45%. For New Caledonia #4 Haze, a slow dry at 18–20°C and 55–60% RH preserves the tropical top notes better than rapid desiccation. Properly cured jars retain a strong nose for months, with only gradual oxidative shifts toward deeper spice and incense.
Sensory evaluations by experienced consumers often score high for distinctiveness and persistence of aroma. Anecdotally, the strain opens a room quickly and lingers, a trait correlated with both terpene abundance and a balanced mix of high-volatility and mid-volatility compounds. This persistence can be a practical consideration for discretion-minded users. For producers, the powerful nose can serve as a brand signature when quality control is consistent.
Flavor Profile and Combustion Characteristics
The flavor tracks the aroma closely, launching with zesty lime, sweet citrus, and a pulpy tropical character reminiscent of mango nectar. Early pulls through a clean glass piece emphasize lemongrass and green tea, while joints highlight pine resin, white pepper, and a faint floral soapiness associated with high terpinolene. On exhale, expect a lingering citrus-pine aftertaste with hints of clove and incense. The overall impression is crisp, sparkling, and surprisingly clean for such a complex bouquet.
Combustion is smooth when the flowers are properly matured and dried slowly. High-terpinolene cultivars can feel sharp if over-dried or harvested too early, leading to a thin, grassy edge. With a 10–14 day dry and 4–8 week cure, the smoke rounds out and shows a silky texture that coats the palate. In vaporization at 175–190°C, fruity and floral elements dominate, while higher temps around 200–205°C unlock spice and incense.
Terpene volatilization is temperature-dependent, and tuning device settings can optimize flavor sequencing. Ocimene and alpha-pinene pop early at lower temps, producing a bright, energizing first impression. Limonene and terpinolene intensify as temperatures rise, and caryophyllene’s spice anchors the tail end. Users often report that flavor endurance remains strong for multiple draws, suggesting robust terpene retention in properly cured samples.
Harshness, when present, usually correlates with insufficient flush, too much nitrogen late in flower, or aggressive drying under 45% RH. Remediating this involves a final two-week nutrient taper, careful EC management, and patient curing with periodic burping of jars. Targeting a final water activity of 0.55–0.62 helps balance burn quality with terpene preservation. When done right, the ash trends light and the palate remains clear.
Paired experiences can amplify perception—citrus seltzers, green apple, or unsweetened iced tea mirror the cultivar’s high notes. For edible or concentrate expressions, live rosin and fresh frozen extracts capture the delicate top notes best. In connoisseur markets, high-terp fractions from New Caledonia #4 Haze-like material are prized for their clarity and lift. These products magnify the strain’s tropical-pine arc and can be exceptional for daytime use.
Cannabinoid Composition and Potency
New Caledonia #4 Haze is best characterized as THC-dominant with low CBD, consistent with a sativa heritage. Across comparable Haze-forward cultivars, THC commonly falls between 16–24%, with exceptional grows exceeding 25%. CBD typically registers below 1%, and often below 0.3% in flower, while minor cannabinoids like CBG may range 0.2–1.0%. Total cannabinoid content can reach 18–28% by weight in well-grown, resin-forward batches.
Potency perception is influenced not just by THC, but by terpene synergy and dosing. Inhaled THC can produce noticeable psychoactive effects at 2–5 mg in sensitive users, while regular consumers may prefer 5–15 mg per session. Given its uplifting terpenoid profile, this strain can feel “stronger than the number” suggests, especially in the first 30–45 minutes. This effect stacking is a known phenomenon with terpinolene-forward sativas.
Time course after inhalation typically shows onset within 2–5 minutes, peak at 20–40 minutes, and a taper over 120–180 minutes. Edible formats shift this curve to a 45–90 minute onset, 2–4 hour peak, and 4–8 hour duration. The cultivar’s bright, cerebral character tends to remain pronounced through the peak and settle into a clear, unfogged comedown. Users often report minimal residual heaviness compared to indica hybrids.
From a lab perspective, batch-to-batch variance is expected with long-flowering sativas sensitive to environment and harvest timing. Late-harvest material can show a slightly higher proportion of oxidized cannabinoids and a more sedative tail. Early harvests often measure marginally lower THC but feel racier and more stimulating. For a balanced experience, many growers target a harvest window with mostly cloudy trichomes and approximately 5–15% amber.
For concentrates, potency can concentrate beyond 70% total cannabinoids in solvent extracts and 60–75% in rosin, depending on process. Yet the perceived “strength” of New Caledonia #4 Haze concentrates still hinges on terpene composition and ratio, not just cannabinoid percentage. Consumers seeking flavor-forward experiences often prioritize terpene content of 5–12% in extracts for this cultivar. These ratios maintain the strain’s signature brightness while ensuring a comfortable ride.
Terpene Profile and Chemotype
The dominant terpene profile of New Caledonia #4 Haze is expected to be terpinolene-led, with supporting roles from ocimene, alpha-pinene, limonene, and beta-caryophyllene. In high-terp sativas, terpinolene can account for 20–40% of the total terpene fraction, especially when plants are harvested at full maturity and dried slowly. Total terpene content in meticulously grown, slow-cured flowers commonly ranges from 1.8–3.0% of dry weight, with occasional outliers above 3.2%. These values are consistent with craft cannabis benchmarks reported across Haze-forward cultivars.
