Written by Ad OpsOverview: What Is Arjan's Haze #3?
Arjan's Haze #3 is a sativa-leaning cultivar bred by Green House Seeds, one of Amsterdam’s most storied seed companies. Designed as the most compact and grower-friendly entry in the Arjan’s Haze series, it prioritizes manageable height and faster finishing compared to classic Haze cuts. Despite the more approachable growth habit, it still aims to deliver the signature cerebral, incense-forward Haze experience.
With a pronounced sativa heritage, this cultivar tends to express uplifting, clear-headed effects and a complex terpene bouquet. Many growers and consumers consider it a bridge between vintage Haze character and modern practicality. Indoor flowering commonly falls in the 9 to 11 week range, positioning it on the earlier end for Hazes.
In terms of potency, typical batches present THC in the mid-teens to low-20s percent by dry weight, with total terpene content frequently in the 1.2 to 2.5 percent range. The combination of terpinolene, limonene, myrcene, and beta-caryophyllene forms a bright, woody, and citrus-incense profile. These metrics make Arjan’s Haze #3 an attractive option for consumers who enjoy classic sativa flavors without extremely long grow cycles.
Origin and Breeding History
Green House Seeds, a breeder known for popularizing many legendary genetics, released Arjan’s Haze #3 as part of a trio created to refine the Haze experience. The #3 phenotype was selected to be shorter, faster to finish, and easier to cultivate compared with long, lanky Haze expressions that can push 12 to 14 weeks in flower. This design decision made it well-suited to indoor environments and temperate outdoor seasons.
The Arjan’s Haze line built on the global reputation of Haze-type sativas, which arose from complex blends of tropical landraces in the late 20th century. While Green House Seeds does not widely publish a precise, full genetic map for #3, the company has consistently framed the lineage as emphatically sativa. The selection strategy focused on preserving incense and lemon-peel aromatics and a clean, active head effect while dialing in structure and finish time.
Through the mid-2000s and 2010s, Arjan’s Haze #3 became a go-to recommendation for growers who wanted a Haze with predictable training responses. Across multiple markets, it garnered a reputation as the most indoor-ready Haze in the series. Its popularity has persisted thanks to stable seed offerings, high germination rates reported by retailers, and a flavor profile that remains distinctly Haze without excessive spiciness.
Genetic Lineage and Sativa Heritage
Arjan’s Haze #3 descends from the broad Haze family tree, which historically combines equatorial sativas from regions such as Southeast Asia and Central and South America. Green House Seeds positions #3 firmly within that sativa heritage while emphasizing a refined, compact phenotype. In practice, this translates to narrower leaflets, longer internodal spacing than indicas, and a pronounced stretch at the flip to 12/12.
Although detailed pedigrees are closely held by many breeders, most growers will recognize typical Haze hallmarks here. The plant expresses a bright, incense-laden terpene profile and a fast, crisp mental onset that is characteristic of terpinolene-forward sativas. The breeder’s selection is intended to tone down excessive height and reduce flower time while preserving the uplifting, creative signature.
Phenotypically, expect a dominant sativa structure with the occasional hybrid-leaning pheno that stacks denser colas. Growers commonly report a 1.5x to 2.0x stretch from the start of flower, which is moderate for a Haze. This manageable architecture is central to Arjan’s Haze #3’s reputation as a sativa that cooperates in tents and mid-height spaces.
Visual Traits and Bag Appeal
Buds from Arjan’s Haze #3 tend to be medium-sized, elongated, and slightly foxtailed, reflecting their sativa heritage. Calyxes often stack in staggered clusters rather than forming perfectly cylindrical spears, creating a textured, stacked look. Trichome coverage is generous, lending a frosty sheen that stands out under bright light.
Coloration typically ranges from light lime to forest green, with orange to deep amber pistils as the flowers mature. Sugar leaves are relatively thin, and the bract-to-leaf ratio is favorable, aiding post-harvest trimming. As the plant ripens, late-flower phenos may display faint lavender tints in cool night temperatures, though this is not universal.
Overall bag appeal is high for a Haze-type, especially when grown under strong lighting and carefully dried and cured. The resin layer enhances the visual contrast against the pistils and fine sugar leaves. Combined with a bright, complex nose, the flowers project both freshness and potency on inspection.
Aroma: From Incense to Citrus
On the first grind, most cuts of Arjan’s Haze #3 release a bouquet that blends church incense, lemon zest, and cedar. A secondary layer brings in sweet herb and faint floral notes, often with a peppery or woody spice. The result is unmistakably Haze, but modernized with cleaner citrus and less barnyard musk.
During cultivation, the aroma ramps up notably in weeks 7 to 10 of flower, which is consistent with monoterpene peak production. In controlled indoor runs, carbon filtration is recommended because terpinolene and limonene volatilize readily at room temperature. Growers report that a single plant can noticeably perfume a small apartment by late flower without adequate filtration.
Post-cure, the nose becomes more focused and layered. Incense and cedar sit up front, lemon-peel brightness pops on break-up, and a lingering sandalwood quality hangs on the exhale. Relative humidity during cure meaningfully modulates this balance, with lower RH leaning woody and higher RH preserving citrus top notes.
Flavor and Mouthfeel
The inhale typically starts with a clear lemon-zest brightness, quickly joined by classic Haze incense and cedar. As the vapor or smoke spreads, subtle sweetness and herbal tones arrive, reminiscent of lemongrass and sweet basil. The finish often brings a peppery edge from beta-caryophyllene with a delicate, drying woodiness.
When vaporized at 175 to 190 C, terpinolene and limonene-derived notes rise to the front and taste cleaner than in combustion. At higher temps or with smoke, the flavor turns spicier and more resinous, emphasizing wood and incense. Many tasters describe a distinctly dry finish, similar to green tea, which accentuates the perception of clarity.
Mouthfeel is light to medium-bodied, without the heavy resin coat common in dense indica chemovars. Proper cure at 60 to 62 percent RH preserves volatile top notes and prevents harshness. When dried too fast or cured below 55 percent RH, the profile skews toward sharp wood and loses its citrus lift.
Cannabinoid Profile and Potency
Most verified lab results for sativa-leaning Hazes place THC in the 14 to 22 percent range by dry weight, and Arjan’s Haze #3 commonly lands within that band. Some breeder-linked data sets for this cultivar have reported mid-teens THC with low CBD, which tracks with consumer reports of a clean, heady effect. CBD typically registers below 1.0 percent, often in the 0.05 to 0.5 percent zone.
Minor cannabinoids can contribute to the energetic feel of many Hazes. CBG often falls between 0.2 and 0.6 percent, while trace THCV is not unusual in sativa-leaning plants and may appear around 0.1 to 0.5 percent. These levels vary by phenotype, grow conditions, and harvest timing, so testing a keeper cut is recommended for consistent outcomes.
Inhalation onset for this chemotype is fast, generally 2 to 5 minutes with peak effects around 15 to 30 minutes. Duration commonly spans 2 to 3 hours for experienced users, with aftereffects tapering gently into a light, non-sedating finish. Edible formulations extend onset to 30 to 120 minutes and can last 4 to 8 hours depending on dose and metabolism.
For dose planning, many consumers find 2.5 to 5 mg THC sufficient for functional daytime use with this profile. Experienced users may prefer 5 to 10 mg inhaled equivalent, especially when vaporizing to capture more terpenes. Given the sativa-forward headspace, sensitive users prone to anxiety should start low and build slowly to find an optimal window.
Terpene Profile and Chemistry
Arjan’s Haze #3 typically exhibits a terpinolene-forward profile complemented by limonene, myrcene, and beta-caryophyllene. In well-grown samples, total terpene content often measures between 1.2 and 2.5 percent by weight, which is robust enough to drive a vivid nose and flavor. A representative distribution might place terpinolene around 0.3 to 0.9 percent, limonene 0.2 to 0.5 percent, myrcene 0.2 to 0.6 percent, and beta-caryophyllene 0.1 to 0.3 percent.
Supporting terpenes such as humulene and ocimene commonly appear in the 0.05 to 0.2 percent range, with linalool occasionally present at trace to 0.1 percent. This matrix produces the incense-citrus-woody triad that defines the Haze experience without overwhelming musk. The relative balance shifts with environment, especially temperature swings late in flower and cure humidity.
From a chemistry perspective, terpinolene and limonene contribute to perceived brightness and alertness, while beta-caryophyllene adds peppery spice and may engage CB2 receptors. Myrcene can soften edges and modestly influence the sense of body relaxation without tipping into sedation at these levels. The interplay helps explain why the cultivar reads as energetic yet controlled.
For flavor preservation, vaporization between 175 and 190 C captures the volatile monoterpenes responsible for citrus and floral edges. Combustion raises delivery of sesquiterpenes like beta-caryophyllene and humulene, skewing the profile to wood and spice. Thoughtful temperature control lets users tailor the experience toward sparkle or depth.
Experiential Effects and Use Scenarios
Arjan’s Haze #3 is commonly described as clear, cheerful, and mentally active. The onset is quick, and the first phase often brings heightened sensory detail, light euphoria, and a subtle increase in motivation. Unlike heavy indicas, body weight is minimal here, preserving mobility and focus for daytime tasks.
As the session develops, many users report creative ideation and a social ease that pairs well with conversation, cooking, or outdoor wandering. The experience typically tops out around the 30-minute mark, then holds steady for 60 to 90 minutes before tapering. This arc suits project blocks, brainstorming sessions, and light exercise like a neighborhood walk or stretching.
Potential side effects mirror those of other sativa-leaning Hazes. In sensitive individuals or at high doses, transient anxiety, racing thoughts, or dry mouth and eyes may appear. Hydration and dose control mitigate most of these issues, and terpene-rich vaporization can feel smoother than dense smoke.
For pairing, consider citrus-forward herbal teas or sparkling water to echo the profile without palate fatigue. Music, photography walks, or journaling often synergize with the cultivar’s bright headspace. Users aiming for evening wind-down may prefer microdoses to avoid over-stimulation close to bedtime.
Potential Therapeutic Applications
Given its sativa heritage and common cannabinoid-terpene pattern, Arjan’s Haze #3 is often explored for mood elevation and daytime function. Users managing low motivation, stress, or situational depression may appreciate its capacity to promote alertness without sedation. The terpinolene-limonene signature aligns with many reports of uplift and cognitive brightness.
For fatigue and attentional drift, small inhaled doses in the 1 to 3 mg THC range can sometimes improve task initiation. Beta-caryophyllene’s CB2 activity and low myrcene levels may contribute to a clean head with mild body ease. People managing headaches should approach methodically, as citrus-forward terpenes can be either helpful or trigging depending on individual patterns.
Pain applications tend to skew toward neuropathic or tension-related complaints rather than deep inflammatory pain. At 5 to 10 mg inhaled equivalent, some patients report lighter perceived muscle tightness and better tolerance for movement-based therapy. However, for severe pain or sleep initiation, a more sedative chemotype may be preferable.
As always, start low and titrate slowly, especially for those prone to anxiety or panic. Combining a terpene-preserving vaporizer with mindful breathing can reduce intensity spikes. Medical decisions should be made with clinician guidance, particularly when other medications or conditions are in play.
Cultivation Guide: Indoors, Outdoors, and Greenhouse
Arjan’s Haze #3 is purpose-built to make Haze cultivation feasible in standard tents and rooms. Indoors under photoperiod lighting, expect 9 to 11 weeks of flower, with most phenos comfortable around 70 to 77 days. A controlled stretch of 1.5x to 2.0x makes it compatible with 150 to 200 cm tents using light training.
Indoor yields of 500 to 700 g per square meter are achievable with high-efficiency LEDs, proper canopy management, and an optimal environment. Under 600 to 1000 watts per square meter photon density equivalence, experienced growers may approach 0.8 to 1.5 grams per watt. Consistent vapor pressure deficit and adequate airflow are important to keep sativa canopies healthy and prevent microclimates.
Outdoors in temperate zones, Arjan’s Haze #3 can reach 150 to 250 cm with topping and exposure to full sun. Harvest windows generally fall from late September to mid-October in the Northern Hemisphere, depending on latitude and fall weather. Yield per plant commonly ranges from 700 to 1200 grams when rooted early, trained, and fed steadily.
In greenhouses, light dep techniques can ensure a mid- to late-September finish, sidestepping October storms. A 10 to 14 day dep window beginning in mid-July at 45 degrees north latitude typically lands harvest around the equinox. For humid regions, greenhouse dehumidification is a prudent investment to maintain 45 to 55 percent RH late in flower.
Because this is a sativa-leaning plant, root volume and oxygenation strongly influence vigor and terpene expression. Indoors, 11 to 20 liter containers with high-porosity media or coco blends work well, while outdoors, 75 to 150 liters are common for season-long runs. Hydroponic or coco systems will shave days off veg and can maximize lateral branching with steady EC.
Training, Nutrition, and Environmental Controls
A low-stress training first, high-stress training second approach works very well for Arjan’s Haze #3. Top once above the fourth to sixth node, then begin lateral tie-downs to create 6 to 12 main sites in a flat canopy. Screen of green is highly effective, filling 70 to 80 percent of net squares before flip to control stretch.
Target a veg canopy PPFD of 300 to 500 and a DLI of 25 to 35 mol per square meter per day. In flower, increase PPFD to 700 to 900 with a DLI in the 40 to 55 range. With supplemental CO2 at 800 to 1200 ppm, PPFD can be safely pushed toward 1000 to 1100 for late flower if temperatures and VPD are in range.
Vegetative temperatures of 24 to 28 C daytime and 20 to 22 C nighttime keep metabolism brisk without stressing leaves. In flower, 22 to 26 C daytime and 18 to 21 C nighttime help preserve terpenes while sustaining growth. Maintain RH at 60 to 70 percent in veg and 45 to 55 percent in flower, tracking a VPD of roughly 0.9 to 1.2 kPa in veg and 1.2 to 1.5 kPa in flower.
For nutrition, sativa-leaning Hazes prefer steady but moderate nitrogen and a balanced calcium-magnesium supply. In coco, many growers run EC 1.2 to 1.6 in veg, 1.6 to 2.0 in early flower, then taper to 1.4 to 1.8 late flower. Keep pH around 5.8 to 6.0 in hydro-coco and 6.2 to 6.6 in soil, with 10 to 20 percent runoff to prevent salt buildup.
Defoliation should be measured and timed. Remove lower fans and weak interior shoots a week before flip, then again at day 21 and day 42 to maintain airflow and light penetration. Avoid extreme stripping that can stall sativa metabolism; aim to open the plant while preserving enough solar panels for continued drive.
Irrigation frequency is dictated by media and root mass, but a pulse approach in coco yields strong results. Multiple small feeds per light cycle stabilize EC and moisture, reducing tip burn risks. In soil, water to full saturation and allow for sufficient dry back to keep roots oxygenated and discourage fungus gnats.
Flowering, Harvest Timing, and Post-Processing
Arjan’s Haze #3 typically stacks best between weeks 5 and 9 of flower, when calyx swell accelerates. Resin production is visually evident by week 6, with a strong terpene surge into week 8. Most growers harvest between days 70 and 77, which balances potency with flavor intensity.
Trichome maturity is the most reliable harvest indicator. Aim for mostly cloudy heads with 5 to 10 percent amber for a bright yet complete effect; all-cloudy and minimal amber yields a racier profile, while 15 to 20 percent amber leans more grounded. Because terpinolene volatilizes easily, avoid prolonged high-temperature lighting in the final week.
A slow, controlled dry preserves the delicate top notes that define this cultivar. Target 60 percent RH at 16 to 18 C for 10 to 14 days with gentle air exchange and no direct airflow on flowers. Stems should snap, not bend, before moving to cure.
Cure in airtight containers at 60 to 62 percent RH for 3 to 6 weeks, burping lightly for CO2 release during the first 7 to 10 days. Ideal water activity for storage is around 0.55 to 0.62, which maintains pliability and aroma without mold risk. Proper curing noticeably amplifies lemon-incense brightness and smooths the peppery finish.
Final yield depends on canopy fill, light intensity, and cultivation skill. Under optimized conditions, expect 500 to 700 g per square meter indoors and 700 to 1200 g per plant outdoors. Post-trim, preserve terpenes by storing in UV-proof glass at cool temperatures with minimal oxygen exposure.
