Cam3 x C99 is a mostly sativa cross developed by Scott Family Farms, a breeder known for meticulous in-house selections and clean, vigorous seed lines. The project combines a proprietary Cam3 cut with Cinderella 99, the celebrated fast-finishing sativa from Brothers Grimm Seeds. The intent, by most grower accounts, was to fuse high-energy clarity with improved resin coverage and a terpene profile that stands out in a competitive market.
Cinderella 99 has long been prized for its uplifting, focused character and quick flowering for a sativa-leaning plant. By pairing it with Cam3, Scott Family Farms sought to stabilize a line that maintains speed and structure while adding deeper complexity to nose and flavor. The result is a hybrid that tends to finish within eight to nine weeks indoors, an appealing window for both home cultivators and commercial rooms.
Reports from growers who have run Cam3 x C99 since its introduction suggest it was bred for balanced performance across media, thriving in coco, living soil, and hydroponic setups. Early adopters also noted that the cross handles training well and tends to express uniformity across phenotypes. This consistency, paired with a high calyx-to-leaf ratio, makes the cultivar efficient to trim and attractive to processors seeking quality input for concentrates.
Because Scott Family Farms keeps many details about Cam3 close to the vest, the cross carries an aura of boutique exclusivity. That hasn’t stopped it from gaining traction wherever sativa-forward cultivars are in demand. In practice, the cultivar delivers the fast, bright lift associated with C99 while layering a more modern resin sheen and a nuanced aromatic top end likely influenced by the Cam3 parent.
Genetic Lineage and Heritage
The lineage marries Cam3, an in-house selection from Scott Family Farms, with Cinderella 99, one of the most important modern sativa-leaning cultivars. Cinderella 99 traces to the Princess line, itself believed to descend from a particularly electric Jack Herer phenotype sourced in the late 1990s and subsequently refined by Brothers Grimm Seeds. This heritage explains the brisk flowering time, pronounced terpinolene-forward aroma in many phenos, and clear-headed, energetic effects.
Cam3’s exact pedigree has not been published, but growers consistently describe it as vigorous, resinous, and expressive in the upper terpene registers. In crosses, it often contributes improved trichome density, a slightly more robust branch structure, and a nuanced aromatic layer that can read as herbal-citrus with a cooling edge. The synergy with C99 typically yields a sativa expression that is both lively and manageable in the garden.
Given the context from Scott Family Farms and grow logs, Cam3 x C99 tends to present as a mostly sativa hybrid, commonly estimated around 65–75% sativa in expression. This aligns with the rapid photoperiod finish (often 56–63 days) and the spear-like bud morphology. The cultivar’s behavior under both high-intensity LED and HPS lighting further supports a sativa-leaning profile marked by stretch, internodal spacing that tightens under training, and a notable appetite for light.
In practice, the C99 parent acts like an efficiency engine, accelerating maturity and providing clarity, while Cam3 contributes extra resin coverage and complexity. The cross manages to retain the nimble, cerebral spirit of classic sativa lines without drifting into the 12–14 week bloom cycles seen in older equatorial genetics. As such, Cam3 x C99 straddles the line between legacy sativa character and modern commercial practicality.
Appearance and Structure
Cam3 x C99 typically forms tall, elegant plants with moderate internodal spacing that tightens under topping and low-stress training. Expect elongated, spear-shaped colas that stack calyxes efficiently, especially when provided with strong side lighting. Leaves often present as medium-narrow blades, a common sativa indicator, with petioles showing lime-green to mid-green tones throughout the canopy.
Under optimal conditions, the cultivar exhibits a favorable calyx-to-leaf ratio, reducing post-harvest labor. Bracts swell late, and resin glands become visibly prominent by week six of flower, creating a frosted appearance that intensifies through finish. Pistils often emerge in bright orange or apricot hues and can deepen toward copper as maturity approaches.
Coloration across phenotypes tends to stay green with occasional blushes of lavender toward the final two weeks if night temperatures drop 3–5°C below day temperatures. Trichome heads are typically bulbous and abundant along sugar leaves, making trim suitable for high-quality ice water hash or dry sift. The overall bag appeal is above average for a mostly sativa line, thanks to dense resin coverage and clean, elongated bud architecture.
In veg, plants respond with strong apical dominance unless topped, and they can stretch 1.5–2.0x after flip. Well-supported branches will carry long colas without lodging, but a single layer of trellis is advised to prevent lean. This combination of poise, resin pop, and trimmed efficiency sets Cam3 x C99 apart from many classic sativas that run light on density or resin.
Aroma and Bouquet
The aromatic profile of Cam3 x C99 balances bright, tropical-citrus top notes with a clean, herbal backbone. Many noses immediately catch hints of pineapple, grapefruit zest, and sweet orange reminiscent of C99’s signature citrus. Beneath that, a cooler, green facet emerges, sometimes reading as spearmint, fresh-cut herbs, or light camphor, a layer plausibly inherited from the Cam3 side.
Breaking the flower intensifies the terpene lift, pushing sweet, high-voltage terpinolene notes that mingle with limonene-driven lemon-lime. A subtle undercurrent of pepper and resin appears on the grind, which is consistent with beta-caryophyllene’s presence. In sealed jars, the bouquet starts out citrus-forward, then settles into a more complex herbal-spice matrix over a few weeks of cure.
Across multiple harvest reports, terp intensity increases notably between week seven and finish, pointing to late-stage terpene biosynthesis. Proper drying and curing at 60–62% relative humidity preserves the sharper citrus while allowing secondary notes to cohere. When mishandled in dry environments below 55% RH, the top notes thin and the profile skews grassy; careful moisture control keeps the bouquet assertive and layered.
Growers who run the cultivar at slightly cooler night temps during the final 10–14 days often report a crisper aromatic snap. This practice seems to favor retention of highly volatile monoterpenes that can otherwise off-gas in warm, dry rooms. The net result is a nose that feels both classic and contemporary: nostalgic C99 brightness with modern herbal precision.
Flavor and Mouthfeel
On inhalation, Cam3 x C99 tends to deliver a sparkling citrus entry followed by sweet tropical tones and a gentle herbal cool-down. Many users describe pineapple candy, white grapefruit, and lemon-lime soda across the first few pulls. As the session continues, a soft green-herbal character appears, with a peppery tickle on the exhale that hints at caryophyllene.
Vaporization at moderate temperatures (175–190°C) accentuates the high-note terpenes, preserving terpinolene’s airy, floral-citrus lift. At higher temperatures (200–210°C), the flavor shifts toward warmer spice, resin, and a slightly woody-herbal finish. Combustion can mute some top notes, but a well-cured sample still holds citrus and tropical character through the mid-bowl.
The mouthfeel is clean and lightly effervescent at lower temperatures, becoming denser and more resinous as heat rises. Resin rings on rolled joints appear readily by the midway point, reflecting the cultivar’s strong trichome output. Ash quality correlates with a thorough flush and steady dry; consistent grey to near-white ash and a smooth draw indicate a well-finished flower.
Pairing the cultivar with citrus-forward beverages, sparkling water, or mild green teas complements its profile without overpowering it. Overly sweet pairings can flatten the high notes, while bitter or tannic pairings like strong black tea can clash with the citrus. In general, the flavor remains articulate across formats, making it a favorite for both flower connoisseurs and rosin makers.
Cannabinoid Profile
Cam3 x C99, as a mostly sativa hybrid from Scott Family Farms, typically tests high in THC with modest minors and low CBD. While lab results vary by environment and phenotype, a realistic total THC range is 18–26%, with peak outliers sometimes touching 28% under high-intensity lighting and optimized fertigation. Total cannabinoids commonly land between 20–30%, reflecting robust resin production.
CBD is generally minimal, often below 0.5% and typically under 0.2% in most phenotypes. CBG appears as a minor constituent in the neighborhood of 0.1–1.0%, influenced by harvest timing and cultivar expression. CBC usually sits in trace to low ranges, about 0.05–0.3%, and THCV may appear in small amounts around 0.1–0.5%, consistent with sativa-influenced lines.
It is important to note that cannabinoid output is sensitive to cultivation variables. Light intensity (e.g., 700–1,000 µmol/m²/s in late flower), balanced nutrient regimes, and stable root-zone conditions (20–22°C) can shift totals meaningfully. Controlled studies show that environmental optimization can raise total cannabinoids by several percentage points compared to suboptimal conditions, and harvest maturity can swing THC and minors by 10–20% relative across a two-week window.
Laboratories typically quantify these compounds via HPLC, reporting results in weight percent of dry flower. Given inter-lab variability of 5–10% relative for THC is not uncommon, growers and patients should interpret numbers as ranges rather than absolutes. For most users, the qualitative profile—clean cerebral lift with minimal sedation—aligns more predictably with the cultivar’s terpene bias than with single-number THC bragging rights.
Terpene Profile
Cam3 x C99 leans toward a terpinolene-forward bouquet in many phenotypes, often supported by limonene, beta-caryophyllene, and ocimene. Total terpene content typically ranges from 1.5–3.5% by dry weight when grown under optimized conditions, with 2.0–2.5% being a common sweet spot in dialed-in rooms. Within that, terpinolene may occupy 0.4–1.0% of dry weight, limonene 0.3–0.8%, and beta-caryophyllene 0.2–0.6%.
Secondary contributors can include myrcene (0.1–0.4%), linalool (0.05–0.2%), humulene (0.05–0.2%), and occasional pinene in trace to low levels. Ocimene, where present, tends to elevate the tropical-citrus character and can sit around 0.05–0.2%. This constellation of monoterpenes and sesquiterpenes is consistent with the observed flavor arc from bright citrus to herbal-spiced exhale.
From a sensory chemistry perspective, terpinolene and limonene provide sparkling top notes and perceived mental brightness. Beta-caryophyllene and humulene contribute warmth, spice, and a gentle grounding effect that rounds out the experience. When dried and cured carefully, the monoterpenes remain buoyant while the sesquiterpenes lend complexity and longevity to the aroma.
Boiling points and volatility have practical implications for consumption and processing. Terpinolene (boiling range roughly 184–186°C) and limonene (~176°C) are readily preserved at low-temp vaporization or careful rosin pressing, whereas caryophyllene (~119°C at reduced pressure; ~262°C atmospheric) and humulene (~198–210°C) persist better under moderate heat. For extractors, a gentle, low-heat cure of solventless concentrates can maintain the cultivar’s signature citrus-herbal balance without off-gassing the fragile top end.
Experiential Effects
Users commonly describe Cam3 x C99 as clear-headed, upbeat, and fast to engage, consistent with its mostly sativa heritage from Scott Family Farms. The onset via inhalation is swift, often within 1–3 minutes, rising to a lively plateau over 10–15 minutes. The mental tone is alert and focused, with many reporting enhanced task engagement and mood lift without heavy body sedation.
Compared to older racy sativas, the cultivar typically avoids jittery overstimulation when consumed in modest doses. A subtle bodily lightness accompanies the cerebral elevation, sometimes with a gentle, buzzing euphoria behind the eyes. Music, design tasks, and light outdoor activity pair naturally with the effect profile, which can stay productive for 90–150 minutes depending on dose and tolerance.
At higher intake, some users may experience transient heart rate elevation and an anxious edge, which is not unusual for terpinolene-forward, high-THC profiles. Those prone to anxiety often find benefit in starting with 1–2 inhalations or using a lower-temperature vaporization setting to reduce rushy onset. Hydration and a calm setting also help channel the cultivar’s energy into creativity rather than restlessness.
The comedown tends to be clean and gentle, leaving minimal fogginess for most. Unlike heavy indica-dominant cultivars, Cam3 x C99 rarely induces couch-lock, making it a daytime or early-evening option. Its clear arc and efficient onset are part of why it appeals to both recreational consumers seeking uplift and medical users looking for functional relief.
Potential Medical Uses
Cam3 x C99’s profile suggests potential utility for mood elevation, stress mitigation, and combating fatigue. The bright, energizing onset can help users break through motivational inertia, which some patients report as beneficial in the context of mild depression or seasonal affective dips. Its clarity supports task initiation and maintenance rather than sedation, potentially aiding those who find heavier cultivars counterproductive during the day.
The cultivar’s terpene ensemble—particularly limonene and terpinolene—aligns with anecdotal reports of reduced perceived stress and improved outlook. Beta-caryophyllene’s activity at CB2 receptors may contribute a subtle anti-inflammatory backdrop, which, in concert with THC, can modulate minor aches and tension. While not a classic analgesic heavyweight, the cultivar may offer daytime relief for low-to-moderate discomfort without dulling cognition.
For attention and focus, some users report improved flow on creative or repetitive tasks, especially at micro to moderate doses. A practical approach involves small, titrated inhalations spaced 5–10 minutes apart until the desired effect emerges. Overconsumption can flip benefits into distraction or edginess, so gradual titration is essential for therapeutic applications.
As with all cannabis-mediated wellness strategies, responses vary widely, and formal clinical data specific to Cam3 x C99 are limited. Individuals with anxiety sensitivity or cardiovascular concerns should approach with caution due to the cultivar’s brisk onset and THC potency. This information is educational, not medical advice; patients should consult a clinician familiar with cannabinoid therapies to tailor dosing and assess risks.
Comprehensive Cultivation Guide
Overview and Growth Habit
Cam3 x C99 is a mostly sativa hybrid bred by Scott Family Farms that marries quick flower times with strong resin output and a buoyant citrus-herbal terpene profile. Expect 1.5–2.0x stretch after flip, so early training and supportive trellising are recommended. The cultivar thrives in a wide range of media, including coco-perlite, living soil, and recirculating hydro, with a mild preference for high oxygenation at the root zone.
Flowering typically completes in 56–63 days indoors, with some phenotypes preferring a full 63–67 days for maximal terpene development. Outdoor harvests cluster around late September to mid-October in temperate climates, depending on latitude and fall weather. Yields in dialed rooms can reach 450–600 g/m² under high-efficiency LEDs, with skilled growers occasionally exceeding 650 g/m² when leveraging elevated CO2 and high daily light integrals.
Germination, Seedling, and Early Veg
Target a gentle start with 22–25°C ambient temperatures and 65–70% RH for germination and early seedling growth. Light intensity should sit around 200–300 µmol/m²/s to prevent stretch while avoiding stress. Maintain media moisture at field capacity without waterlogging; seedlings are sensitive to hypoxic conditions in the first 10–14 days.
By day 10–14, gradually raise PPFD to 300–450 µmol/m²/s and begin a light feeding program at EC 0.8–1.1 (400–550 ppm 500-scale). Aim for a balanced NPK early veg formula with ample calcium and magnesium to support quick leaf expansion. Keep VPD in the 0.8–1.1 kPa range to encourage healthy transpiration without over-drying tender tissues.
Vegetative Growth, Training, and Canopy Design
In veg, Cam3 x C99 responds well to topping at the 4th–6th node to break apical dominance and encourage a level canopy. Pair topping with low-stress training and, if needed, light supercropping of taller leaders to even out height. A single layer of trellis or a SCROG net installed in late veg can guide lateral growth and prepare sites for even light distribution.
Increase PPFD to 450–650 µmol/m²/s as plants enter robust veg, and consider 18/6 or 20/4 light cycles depending on thermal control and energy costs. Maintain EC around 1.2–1.6 in coco or hydro and feed living soils with appropriately mineralized amendments and periodic compost teas. Keep day temperatures 24–27°C, night 20–22°C, and RH 55–65% with VPD 1.0–1.2 kPa to promote sturdy branches.
Transition to Flower and Early Bloom Management
Prior to flip, ensure a clean underside by removing weak inner growth and lower popcorn sites that will not reach productive light levels. This pre-flip lollipop strategy improves airflow and redirects resources to tops. Flip when the canopy is 60–70% of the final target height, accounting for the 1.5–2.0x stretch.
During weeks 1–3 of flower, raise PPFD to 650–800 µmol/m²/s and gradually shift to a bloom nutrient profile higher in phosphorus and potassium. EC in coco/hydro can move to 1.6–2.1 (800–1050 ppm 500-scale) as appetite increases. Keep RH at 50–60% and VPD 1.1–1.3 kPa to balance rapid growth with mold prevention.
Mid Bloom: Resin, Density, and Environmental Control
By weeks 4–6, flowers stack and resin heads proliferate; this is a critical window for terpene preservation and density building. Push PPFD to 800–950 µmol/m²/s under LEDs if CO2 remains ambient, or 950–1,150 µmol/m²/s with supplemental CO2 at 800–1,200 ppm. Maintain temps 24–26°C day and 20–22°C night, keeping RH 45–55% to reduce Botrytis risk while sustaining terpene synthesis.
Ensure strong, laminar airflow across and below the canopy, and avoid direct fan blasts that desiccate pistils. Light defoliation of large fan leaves casting heavy shade can enhance penetration to interior bud sites. Avoid over-defoliating; sativa-leaning plants value leaf area for photosynthate production, and excessive stripping can depress yields by 5–15%.
Late Bloom, Ripening, and Harvest Timing
In weeks 7–9, monitor trichome development closely with a 60–100x loupe. For a bright, energetic effect, many growers target a harvest at mostly cloudy trichomes with 5–10% amber; extending to 10–15% amber can add a touch more body effect. Pistils should be largely receded and calyxes inflated, with aromatic intensity peaking in the final 7–10 days.
Slightly cooler nights (18–20°C) during the last 10–14 days can sharpen volatile monoterpenes. Avoid dramatic temperature swings that stress the crop or trigger foxtailing in high-PPFD environments. Many growers reduce EC in the final 7–10 days for a cleaner burn; in soil systems, this may be as simple as water-only finishing.
Substrates, Irrigation, and Nutrition
In coco, aim for 10–20% runoff per feed to avoid salt buildup, irrigating 1–3 times per day in flower depending on pot size and plant demand. Typical EC ranges: 1.2–1.6 in veg, 1.6–2.1 in mid bloom, tapering slightly if leaf tips show persistent burn. Keep root-zone temperatures at 20–22°C for optimal nutrient uptake and oxygenation.
Living soil growers should build a well-aerated mix (e.g., 30–35% aeration component) and ensure a comprehensive mineral base with attention to Ca:Mg ratios near 3:1. Top-dress phosphorus and potassium sources just before flip and again at week 3–4 if needed. Supplemental silica can strengthen cell walls, and magnesium sulfate applications can support chlorophyll stability under intense light.
Lighting, CO2, and DLI Targets
Under high-efficiency LEDs, target a DLI of 35–45 mol/m²/day in late veg and 45–55 mol/m²/day in flower for strong biomass and resin development. At ambient CO2, PPFD of 800–950 µmol/m²/s in late bloom is a productive ceiling for many phenotypes. With CO2 enrichment at 800–1,200 ppm, pushing to 950–1,150 µmol/m²/s can increase yield by 10–20% if nutrition and irrigation keep pace.
Even canopy distribution is crucial; light uniformity (U) above 0.7 helps reduce larf and enhances overall quality. Keep fixtures at manufacturer-recommended heights and verify with a PAR meter; sativa-leaning plants can tolerate moderate intensity but are sensitive to hot spots. Incremental increases prevent light shock and preserve top-end terpenes.
Plant Training and Canopy Control
Cam3 x C99 responds exceptionally well to SCROG and manifold training, enabling 8–16 evenly developed tops per plant in a 5–10 gallon container. If running a sea of green, consider shorter veg times and minimal topping to limit excessive stretch after flip. Supercropping during early stretch can tame dominant leaders and redistribute auxins for more uniform stacking.
Apply defoliation in two light passes—one late veg or day 21 post-flip, and another around day 35–42 if needed—to open the canopy. Keep at least 60–70% of functional foliage intact to sustain photosynthesis. Inadequate support is a common source of yield loss; install trellis early and adjust ties as colas gain mass.
Pest, Pathogen, and IPM Considerations
As a resinous, sativa-leaning cultivar, Cam3 x C99 benefits from proactive integrated pest management. Maintain cleanliness, quarantine new clones, and rotate benign foliar treatments in veg (e.g., biologicals, essential oil blends at safe rates) to deter common pests like spider mites and thrips. Cease foliar applications once flowers set to protect trichomes and prevent residue.
Humidity management is central to mold prevention in later bloom. Keep RH below 55% after week 5 and ensure strong air exchange to minimize microclimates in dense clusters. Sanitize tools, avoid overcrowding, and remove senescent leaves early to reduce pathogen pressure.
Outdoor and Greenhouse Adaptation
Outdoors, the cultivar prefers warm, dry late seasons and performs best in regions where September–October rains are limited. Provide ample staking or caging due to long colas and the risk of wind damage. With full-sun exposure and healthy soils, single plants can exceed 500–1,000 g per plant, though outcomes vary widely with climate and management.
In greenhouses, leverage environmental controls to manage humidity and extend shoulder seasons. Light dep can bring the harvest into more favorable weather windows, reducing botrytis risk. Use horizontal and vertical airflow strategies to maintain uniform conditions around tall, slender flower sets.
Harvest, Drying, and Curing
Aim for a slow dry at 15–20°C and 58–62% RH for 10–14 days, preserving volatile monoterpenes and preventing chlorophyll lock-in. Gentle airflow that never directly hits hanging flowers will reduce case-hardening and preserve trichome integrity. Stems should snap, not bend, before moving to cure.
For curing, maintain 60–62% RH and burp jars daily for the first 7–10 days, then weekly for an additional 3–5 weeks. Terpene complexity deepens noticeably by week 3–4 of cure, and many users find the citrus-herbal balance peaks around 4–8 weeks. Properly cured Cam3 x C99 rewards with brilliant nose, articulate flavor, and a polished, energetic effect that reflects the pedigree.
Yield Benchmarks and Quality Targets
In optimized indoor rooms, 450–600 g/m² is a realistic yield band, with boutique-quality flower often landing near the middle of that range. Concentrate processors value the cultivar’s resin coverage; solventless yields of 3–5% from well-grown material have been reported in analogous sativa-leaning, terpinolene-dominant lines. The true hallmark of success is terpene retention—maintaining total terpene content in the 2.0–3.0% range after cure typically correlates with top-shelf sensory performance.
Common Pitfalls and How to Avoid Them
Over-stretch and uneven canopies reduce light-use efficiency; mitigate with early topping, SCROG, and timely supercropping. Excessive defoliation in a sativa-leaning plant can stunt density and lower yields by double-digit percentages; prune conservatively. Underestimating late-bloom humidity needs can invite botrytis—keep air moving and RH managed during the final weeks when colas are densest.
Nutrient imbalances—especially calcium, magnesium, and potassium—can manifest under high PPFD; maintain balanced feed and monitor runoff EC and pH (5.8–6.2 in coco, 6.2–6.8 in soil). Lastly, rushing the dry and cure is the fastest way to mute the cultivar’s signature citrus-herbal top end; the patience spent here often separates premium results from average ones.
