Super Silver Haze x Blueberry Temple x Blueberry Hill is a mostly sativa hybrid crafted by Off Grid Seed Co., a breeder known for crossing classic pillars with boutique, fruit-forward lines. The project marries the electrifying, incense-citrus lift of Super Silver Haze with the jammy depth and calming edges of two Blueberry-derived selections. The breeder intent reads clearly in the phenotype expressions reported by growers and testers, who describe tall, branchy plants with a haze backbone and pronounced berry aromatics. For consumers and cultivators seeking a modern sativa that still delivers old-school character, this cross sits at a fascinating intersection of vigor, flavor, and nuance.
Super Silver Haze earned its place in the pantheon as a Cup-winning haze admired for its production and soaring mood elevation. According to Greenhouse Seeds, classic Super Silver Haze develops long branches, thrives in a ScrOG, responds well to LST, and commonly tests near 19 percent THC, setting an expectation for strong but manageable potency. Blueberry lines, popularized since the late 1990s, contributed sweet esters, myrcene-lush relaxation, and the iconic berry-perfume that helped redefine modern dessert cultivars. Off Grid Seed Co. drew from those strengths to target a sativa that accelerates the mind while keeping the body composed.
The timing of this cross also reflects a market that, from 2020 through 2021, leaned heavily into terpene-rich, dessert-leaning varieties. Leafly’s harvest roundups featured heavy-hitter families like Gelato, Zkittlez, Cake, and Glue while their Buzz column highlighted lemon-leaning terp profiles rising in popularity. In that wave, an energetic haze brightened by bona fide blueberry sweetness feels both nostalgic and contemporary. The resulting chemotype tends to be terpene-forward, sculpting an aroma that cuts through crowded menus and retains character post-cure.
Because Blueberry Temple and Blueberry Hill are less broadly documented than flagship cuts, their detailed pedigrees remain partially opaque, a reality echoed by strain genealogy aggregators that often list unknown or partially traced branches. That is common in modern breeding, where standout phenotypes are selected, stress-tested, and then fixed through line work even when the full ancestry chain is not fully public. In this cross, the practical results matter most to growers and patients, who prioritize stability, vigor, and repeatable flavor over perfect ancestral footnotes. Off Grid Seed Co. delivers a blend that reads consistent across environments while leaving room for pheno expression.
Genetic Lineage and Inheritance
At its core, this hybrid leans heavily into the sativa posture of Super Silver Haze, a triad descendant of Skunk, Northern Lights, and Haze that is known for extended flowering, high calyx-to-leaf ratios, and a soaring cerebral effect. The two Blueberry parents contribute anthocyanin potential, ester-heavy fruit aromatics, and a body-friendly smoothness that reins in the raciest edges of haze. As a result, most growers should expect a plant that stretches 1.5x to 2x after flip, builds elongated spears, and stacks sugar-coated calyxes with more density than a pure haze. Phenotypic variation expresses primarily in berry intensity, color shifts, and terpene tilts toward either citrus-incense or baked-berry jam.
Inheritance patterns favor dominant sativa morphology with intermediate flowering times. Super Silver Haze lines often run 10 to 11 weeks, while classic Blueberry is closer to 8 to 9 weeks; this cross tends to settle around 9 to 10 weeks in optimized indoor conditions. Expect internodes in the 5 to 8 centimeter range during mid-veg under high PPFD, with tighter node spacing achievable via cool nighttime temperatures and strong blue spectrum. Outdoors, the frame shows sturdy lateral branches capable of supporting ScrOG screens and soft ties without splitting when well staked.
Chemically, the haze ancestry encourages terpinolene, ocimene, and pinene dominance, while the Blueberry side reinforces myrcene, linalool, and caryophyllene. That tug of war often lands in a terpene bouquet that blends citrus zest with sugared berries and light incense or cedar. Total terpene content in modern, well-grown sativa hybrids commonly measures between 1.5 and 3.5 percent by dry weight, and this hybrid falls right within that envelope when dried and cured at 60 to 62 percent relative humidity. The cannabinoid spine is THC-forward with consistently minor CBD, plus trace THCV and CBG typical of haze-influenced lines.
From a breeder’s standpoint, the cross aims to transmit vigor without sacrificing resin texture or bag appeal. The Blueberry components reinforce trichome head size and resin stickiness, supporting both solventless and hydrocarbon extraction formats. Meanwhile, the haze structure ventilates colas, helping reduce botrytis risk in dense canopies with suboptimal airflow. When dialed correctly, the genetic pairing balances showpiece aromas with practical garden performance.
Appearance and Morphology
Mature plants display a medium-tall to tall profile with a central cola and pronounced lateral branching, aligning with the Super Silver Haze reputation for long branches and training responsiveness. In veg, leaves skew narrow with serrations that sharpen under intense light, while petiole color remains green to light magenta depending on feed and temperature. As flowering advances, calyxes stack into segmented spears with medium density, avoiding the ultra-compact golf balls that trap humidity and invite mold. Trichome coverage is abundant and glassy, giving the buds a frosted, luminescent look under white LEDs.
Color expression frequently nods to the Blueberry parentage. Under nighttime lows at 60 to 64 Fahrenheit during late bloom, expect anthocyanin flares ranging from lavender sugar tips to full violet bracts in cooler phenos. Pistils begin tangerine to coral and mature toward russet, lending a warm tone against silver resin. The best showings feature a photogenic contrast of icy trichomes over faint purple blushes and sunset pistils.
Internodal spacing is medium, typically 5 to 8 centimeters under 700 to 900 PPFD in veg and 900 to 1,100 PPFD early flower without supplemental CO2. Stretch averages 1.5x to 2x, which favors canopies trained flat under a ScrOG to produce uniform top sites. The plant responds predictably to topping at fifth or sixth node and can be steered into an even net with two to three weeks of veg post-top. LST and soft-tying avoid stem stress fractures while enhancing lateral exposure and airflow.
Bud architecture trends toward elongated, foxtail-tinged tips on the haze-leaning phenos and tighter, bullet-shaped buds on the blueberry-leaning side. Even the denser phenos maintain enough calyx relief to dry evenly without overdrying the exterior. Sugar leaf coverage is moderate, easing trim while still offering quality material for dry sift or ice water hash. Finished buds average medium size with high resin density and a tactile stickiness that persists after a proper cure.
Aroma and Flavor Profile
On first grind, expect a bright mix of lemon zest, sweet blueberry compote, and a faint line of incense or cedar shavings. The top note is often a haze-citrus that reads like candied lemon peel, while the heart note leans baked berry tart and raspberry jam from the Blueberry side. Beneath those lies a gentle green-herbal thread akin to lemongrass and faint basil, plus a whisper of sweet earth. In jar or bag, the dry pull can reveal vanilla sugar and a floral lift consistent with linalool hints.
Combustion or vaporization brings layered transitions. At lower temps around 180 to 190 Celsius in a dry herb vape, the flavor skews bright and fruit-forward, delivering lemon-blueberry candy with a sprig of mint. As temperature climbs past 200 Celsius, deeper wood, pepper, and bread crust undertones from caryophyllene and humulene appear, adding dimension without muting the fruit. In glass, the exhale leaves a syrupy blueberry echo that hangs for several breaths.
Mouthfeel is slick but not heavy, reflecting high monoterpene presence, especially terpinolene and ocimene in haze-leaning phenos. That volatility gives a room-filling diffusion, so the strain announces itself from across a session space. Ash can burn light when properly flushed and dried, preserving the candied fruit from first bowl to last. A cold cure in airtight glass accentuates the pie-filling sweetness and reduces any sharpness on the nose.
Aromatically, this hybrid rides a modern wave where lemon, fruit, and dessert backbones dominate dispensary menus. Leafly’s trend reporting in 2020 and 2021 highlighted consumer gravitation to terpenes like limonene, caryophyllene, and other citrus-forward molecules, and this cross slots right into that demand. The difference is its antiquity of haze incense under the fruit, giving a bridge between 1990s sativa character and 2020s confectionery profiles. That blend makes it memorable on both the sniff test and the palate.
Cannabinoid Potency and Laboratory Expectations
While lab data for every batch varies by environment and phenotype, a realistic potency window can be defined using parental benchmarks and modern sativa hybrid trends. Super Silver Haze lines commonly test in the upper teens to low twenties for THC, with Greenhouse Seeds citing a typical figure around 19 percent. Blueberry derivatives frequently land between 16 and 22 percent THC, with modest CBD generally under 1 percent. In practice, this cross tends to chart 18 to 24 percent THC by dry weight when cultivated under high-intensity lighting and cured correctly.
Breakdown by acid and neutral forms typically shows THCA dominating at 18 to 26 percent pre-decarboxylation, converting to 16 to 23 percent THC post-decarb depending on moisture correction and testing protocol. CBD is generally trace at 0.05 to 0.5 percent, while CBG often lands between 0.3 and 1.0 percent. THCV, a haze-associated minor, may present between 0.2 and 0.7 percent in select phenotypes, lending a brisk top note to the psychoactivity. Total cannabinoids for high-performing batches can push 22 to 28 percent when terpenes are also abundant.
Potency expression correlates strongly with cultivation parameters. Under 900 to 1,200 PPFD in flower without CO2, expect the lower half of the range, while 1,200 to 1,500 PPFD with 1,200 to 1,500 ppm CO2 can push THCA materially higher. Proper drying to 10 to 12 percent moisture and water activity near 0.60 maximizes lab accuracy and preserves terpenes that synergize the experience. Overdrying below 9 percent moisture can reduce apparent terpene content and flatten the effect despite unchanged THC readings.
It is important to contextualize potency within market trends. In Leafly’s recent trend summaries, many popular cultivars showcase high THC alongside dominant terpenes that define the subjective quality of the high. This cross follows that template, delivering competitive THC while emphasizing aromatic complexity that elevates the perceived strength. Consumers often report that batches in the low twenties feel more powerful than their numbers suggest due to terpene synergy and fast cerebral onset.
Dominant Terpenes and Aromatic Chemistry
The terpene profile most frequently centers on terpinolene, myrcene, limonene, and ocimene, supported by alpha-pinene, beta-caryophyllene, and linalool as secondary players. In tested sativa-dominant hazes, terpinolene can range from 0.3 to 0.9 percent by weight, contributing the bright, piney-citrus lift and airy diffusion that defines the top note. Blueberry ancestry contributes myrcene in the 0.2 to 0.8 percent window, carrying the sweet, musky berry and subtle couch-melt rounding to the effect. Limonene often lands between 0.2 and 0.6 percent, supplying the candied lemon rind that reinforces the haze citrus.
Ocimene adds a green, almost tropical sweetness that supports the berry jam impression at 0.1 to 0.4 percent. Alpha-pinene and beta-pinene together can total 0.1 to 0.3 percent, sharpening mental clarity and edge definition while complementing the cedar-incense nuance. Beta-caryophyllene often sits at 0.1 to 0.3 percent, lending pepper-spice and potential CB2 receptor engagement that some users associate with body comfort. Linalool is typically a trace to minor contributor at 0.05 to 0.2 percent, yet it helps polish the floral back end and soften any anxiety spikes.
Total terpene content in well-grown indoor flower commonly falls between 1.5 and 3.5 percent by dry weight for this cross. Outdoor and greenhouse batches can vary more widely, landing from 1.0 to 2.5 percent depending on climate and harvest timing. Early chop tends to favor citrus-haze brightness and reduce the jammy tone, while late chop deepens myrcene and caryophyllene for thicker, sweeter aromatics. A slow dry at 60 degrees Fahrenheit and 60 percent relative humidity preserves monoterpenes that otherwise volatilize quickly, keeping the top note lively.
Consumer preference data across 2020 to 2021 showed strong traction for lemon and dessert-leaning terpene sets, a trend highlighted in Leafly’s coverage of harvest favorites and trending cultivars. This hybrid leans into that preference while preserving lineage authenticity via the haze incense line. The result is a chemical bouquet that pleases both nostalgia-driven haze fans and modern fruit chasers who demand distinctiveness on the nose. That dual appeal makes it an excellent candidate for premium flower shelves and rosin programs.
Experiential Effects and Use Cases
The onset is fast for inhaled routes, with many users reporting a perceivable lift within one to three minutes and a crest around 10 to 15 minutes. The headspace clears and brightens first, often enhancing color saturation and auditory detail while encouraging light conversation. Body feel remains mobile and springy rather than heavy, an inheritance consistent with sativa-forward hazes. As the session continues, a blueberry sweetness lingers on the palate, which some users associate with a comforting undercurrent amid the energetic top end.
Duration for inhaled flower typically spans two to three hours at moderate doses, with a gentle runway rather than an abrupt drop. The mid-phase can feel task-friendly, especially for creative drafting, light chores, or nature walks, while intense analytical work may require a microdosed approach to avoid over-stimulation. Many report reduced perception of minor aches without somnolence, an effect pattern consistent with THC plus caryophyllene and myrcene in modest balance. In social settings, this hybrid trends to laughter and optimism rather than introspective quiet.
Dose sensitivity matters, particularly for users with anxiety predispositions. Hazes can trigger racing thoughts at high doses, so beginners should start with small inhales and pause for 10 minutes to gauge intensity. The Blueberry components help smooth the edge, but the core remains brisk and alerting. Hydration and a snack can help stabilize if the experience tips too racy, as can a terpene counter like linalool-rich lavender or a small dose of CBD.
Compared to classic Super Silver Haze, this cross reads slightly more grounded and confectionary. The added fruit makes it approachable to palates who find straight haze too sharp or astringent. Meanwhile, it retains the clean-limbed motivation that differentiates sativas from dessert-heavy indicas used for evening wind-down. In short, it is a daytime strain that still knows how to be kind to the body.
Potential Medical Applications
While individual responses vary, the cannabinoid-terpene ensemble here suggests potential utility for mood elevation, fatigue reduction, and certain types of neuropathic or inflammatory pain. THC has supportive evidence for neuropathic pain reduction in systematic reviews, and beta-caryophyllene may modulate inflammatory pathways via CB2 activity, offering a complementary mechanism. Myrcene’s sedative reputation is dose-dependent, but at moderate levels it can ease muscle tension without overriding the sativa clarity. Limonene and linalool together have been studied for anxiolytic properties, though outcomes depend on dose, set, and setting.
For patients with low mood or anhedonia, the fast onset and bright tonality may help initiate activity and break through motivational inertia. Individuals with migraine sensitivity should start conservatively, as terpinolene-rich profiles can be stimulating, yet some users report improved comfort when dosing at the earliest aura signs. Those managing ADHD-like symptoms sometimes find sativas useful for task initiation, but careful titration is essential to avoid overstimulation. Daytime chronic pain patients may appreciate the mobility-preserving relief with reduced sedation compared to heavy myrcene-dominant indicas.
Appetite stimulation is moderate and tends to emerge in the tail end of the experience. Nausea relief is possible through THC-mediated mechanisms, making it a candidate for patients dealing with appetite suppression from medications. However, for severe insomnia or late-night use, a heavier cultivar may be preferable, as this profile lifts rather than lulls. Patients sensitive to anxiety should pair small doses with calming rituals and consider adding 5 to 10 milligrams of CBD to modulate the ceiling.
As always, medical use should be discussed with a clinician familiar with cannabinoid therapeutics, especially when combining with other medications. Start low and go slow remains the safest framework. Record strain name, dose, route, time, and effects across several sessions to identify personal patterns. Over a week of observation, small adjustments of 10 to 20 percent in dose can optimize benefits while minimizing side effects.
Comprehensive Cultivation Guide: From Seed to Cure
Genetics and vigor together make this hybrid workable for both intermediate and advanced growers. Indoors, plan for a medium-tall frame and implement training early to capitalize on long branching inherited from Super Silver Haze. Greenhouse Seeds notes that SSH thrives in ScrOG and responds well to LST, and those same tactics pay dividends here. Outdoors, a warm, semi-arid to Mediterranean environment with ample sun will bring out resin and berry aromatics while keeping botrytis risk manageable.
Germination typically completes within 24 to 72 hours using a 1 percent hydrogen peroxide soak for 12 hours followed by moist paper towel at 75 to 78 Fahrenheit. Transplant sprouted seeds into a light, aerated medium, such as a 70-30 mix of coco coir and perlite or a living soil with 20 percent pumice for structure. Maintain root zone pH at 5.8 to 6.2 for coco and 6.3 to 6.7 for soil. Early veg EC can start at 0.8 to 1.2 mS/cm, stepping up as leaves darken and growth accelerates.
Vegetative growth prefers high light and active airflow. Target 700 to 900 PPFD with a blue-leaning spectrum to minimize stretch while stacking nodes, and hold temps near 78 to 82 Fahrenheit with 60 to 70 percent RH for a VPD around 0.8 to 1.0 kPa. Top at the fifth or sixth node, then begin LST within two days to shape a flat canopy for ScrOG. Allow 10 to 21 days of veg post-top depending on target canopy size, remembering the 1.5x to 2x stretch after flip.
Nutrition in veg should deliver a balanced NPK with emphasis on calcium and magnesium for strong cell wall development under high light. In coco, a target feed might average N at 120 to 160 ppm, P at 40 to 60 ppm, and K at 150 to 220 ppm, with Ca at 100 to 140 ppm and Mg at 40 to 60 ppm. Silica at 30 to 50 ppm improves mechanical strength and heat tolerance. Observe leaf posture daily and adjust EC up in 0.1 to 0.2 increments to chase optimal turgor without tip burn.
Transition to flower by reducing RH to 55 to 60 percent and maintaining a slight night drop of 5 to 7 degrees Fahrenheit to encourage tight stacking and color development later. Early flower PPFD can rise to 900 to 1,100 without CO2, advancing to 1,100 to 1,300 by week three to five if leaves pray and runoff EC remains stable. With CO2 enrichment to 1,200 to 1,500 ppm, PPFD can climb to 1,400 to 1,600 for experienced growers with excellent environmental control. Keep canopy uniform by continuing LST or tucking into the screen until day 14 post-flip.
Flowering time averages 63 to 70 days, with haze-leaning phenos occasionally stretching to day 74. Watch for rapid calyx swell from week six onward and avoid overfeeding nitrogen to keep resin bright and avoid grassy notes. Shift nutrition to a bloom bias with N at 80 to 120 ppm, P at 60 to 90 ppm, and K at 200 to 300 ppm, maintaining Ca at 120 to 150 ppm and Mg at 50 to 70 ppm. Sulfur support via Epsom or micronutrient blends helps terpene synthesis, especially for citrus and berry volatiles.
Canopy management is crucial because of the long-branch architecture. Defoliate lightly around day 21 and again at day 42, removing large fan leaves that shadow bud sites while preserving sufficient photosynthetic area. This cross stacks spears that appreciate airflow, so place oscillating fans at multiple heights and maintain 0.9 to 1.2 m/s airspeed at canopy without leaf flutter. Keep RH between 48 and 55 percent mid to late flower to reduce mold risk while preserving terpene retention.
Integrated pest management should be preventative. Use sticky cards to monitor fungus gnat and thrip pressure and employ soil drenches of Bacillus thuringiensis israelensis if larvae appear. Predatory mites such as Amblyseius swirskii and Amblyseius andersoni help suppress whitefly and broad mite issues in warm rooms. Foliar sprays are best avoided past week two of flower to protect trichome heads and flavor purity.
Watering strategy depends on media. In coco, aim for 10 to 20 percent runoff per feed to prevent salt buildup and keep daily irrigations in flower when pots are light, often one to three times per day in 1 to 3 gallon containers. In soil, water to full saturation and then allow 30 to 50 percent of the container moisture to be used before the next irrigation, which often translates to every two to four days depending on pot size and VPD. Keep runoff EC within 0.2 to 0.4 mS/cm of feed EC to guard against hidden lockouts.
Yield potential is competitive for a sativa-leaning hybrid when canopies are trained flat. Indoors, expect 450 to 600 grams per square meter under 600 to 800 watts of efficient LED lighting, with top-flight rooms surpassing 650 g/m2 when dialing CO2 and PPFD. Outdoors, healthy plants in 50 to 100 gallon fabric pots can finish between 600 and 900 grams per plant in full sun. Density remains manageable, so large colas finish with fewer hidden botrytis hotspots compared to ultra-dense indica doms.
Harvest timing affects both effect and flavor. For an energetic profile with more citrus snap, chop around 5 to 10 percent amber trichomes with the balance cloudy, typically at day 63 to 67. For a fuller berry dessert character and slightly deeper body feel, wait to 10 to 15 percent amber around day 68 to 72. Always sample lower and upper cola sites, as top buds may amber faster under high intensity.
Drying is where this cultivar’s aromatic assets are protected or lost. Aim for 10 to 14 days in a dark space at 60 degrees Fahrenheit and 60 percent RH, with gentle air exchange but no direct airflow on flower. Whole-plant hang or large branch hang slows moisture migration, preserving monoterpenes like terpinolene and ocimene that readily volatilize. Target a final moisture content of 10 to 12 percent and water activity around 0.58 to 0.62 before initiating cure.
Curing should proceed in airtight glass at 60 to 62 percent RH using calibrated packs only if needed. Burp jars daily for the first week, then every two to three days for the next two weeks to remove residual moisture and exchange off-gassed volatiles. A four to six week cure amplifies blueberry jam notes and rounds the lemon haze edge into a candied finish. Properly cured flower maintains bright aroma for months when stored in the dark at 60 to 70 Fahrenheit.
For extraction, the strain’s resin heads present well for both solventless and hydrocarbon methods. Ice water hash yields in the 3 to 5 percent range of starting material are achievable on trichome-rich phenos, with rosin pressing at 190 to 205 Fahrenheit delivering terpene-forward sap. Hydrocarbon extraction preserves the complex lemon-blueberry-incense top notes and can produce stable sugar or sauce textures that showcase the cultivar’s layered aromatics. Decarboxylation for edibles should be conservative to protect delicate volatiles, favoring 220 to 230 Fahrenheit for 35 to 45 minutes.
Outdoors, site selection dictates success. Choose sun-exposed locations with strong morning light to dry dew quickly and mitigate powdery mildew. Blueberry ancestry can be moisture-sensitive late season, so leaf thinning and wide plant spacing help airflow. Organic mulches and living cover keep root zones cool and support microbial communities that bolster secondary metabolite production.
In greenhouse environments, ventilation and humidity control are paramount as the resin-heavy colas mature. Shade cloth at 10 to 20 percent can temper heat spikes without sacrificing DLI, and roll-up sides keep leaf temperatures within 2 to 4 degrees of ambient to protect terpenes. Sulfur burners should never be used in bloom due to flavor contamination and potential trichome damage. Instead, maintain preventive IPM and dehumidification to hold VPD steady between 1.1 and 1.4 kPa in mid to late flower.
Finally, phenotype selection is worth the time investment if running multiple seeds. Mark plants with the strongest lemon-blueberry nose in mid-flower and observe resin coverage, bud density, and ease of trim. Clone the top two or three candidates and run them again to confirm repeatability, as environmental shifts can slightly reorder terp expression. The best keeper will deliver a balanced spear structure, saturated berry-citrus aroma, and a cheerful, clear daytime effect that validates the breeding intent.
