Written by Ad OpsOrigins and Breeding History of Madcap Princess
Madcap Princess is a modern cultivar developed by 2 Guns and a Guy Seed Company, a boutique breeder known for hunting vigorous, resinous indica-leaning lines. The strain is positioned as mostly indica in its heritage, a detail that aligns with the breeder’s focus on compact plants and dense, terpene-rich flowers. While the precise parental cross has not been publicly disclosed, internal breeder notes and grower reports consistently describe its morphology and effect profile as classic indica dominant. The result is a cultivar tailored for growers who prize structure, reliability, and a soothing end-user experience.
The development trajectory for Madcap Princess appears to have emphasized stable internodal spacing, stout branching, and high calyx production. Breeders commonly select these traits over multiple filial generations to reduce phenotypic variability; in many modern lines, stabilization typically occurs over F3–F5 generations. Although the exact filial generation for Madcap Princess is not published, the cultivar’s reported consistency suggests that meaningful stabilization work has been completed. In practice, that means most plants from seed will land within a relatively narrow band for height, finish time, and nose.
2 Guns and a Guy Seed Company has built a reputation for releasing lines that wash well for hash makers and cure cleanly for flower enthusiasts. Indica-leaning cultivars often excel in those categories because they tend to develop tightly packed heads and abundant resin gland density. Growers report resin production that holds up under trimming and post-harvest handling, a sign of robust cuticle structure. That trait helps maintain terpenes after drying, which can preserve 70–85% of measured terpene content when low-and-slow drying protocols are used.
Madcap Princess likely emerged from a larger pheno-hunt that screened dozens of candidates for expression, resilience, and test results. Typical pheno-hunts by boutique breeders evaluate 50–200 seeds to identify a keeper mother, with selection criteria weighted toward aroma, potency, and yield. From there, a backcross or sibling selection can lock in desirable traits while reducing outliers. The end product is a cultivar that behaves predictably under a range of environments, which is a hallmark of professional breeding programs.
Genetic Lineage and Phenotypic Expectations
The breeder identifies Madcap Princess as mostly indica, which usually implies a genetic composition above 65% indica influence. In practical terms, this tends to produce broader leaflets, tighter internodal spacing, and a more compact stature than sativa-dominant counterparts. Indica-leaning plants commonly finish in 56–63 days of flowering under 12/12 photoperiod, and Madcap Princess is reported to align with that window. The cultivar’s canopy architecture typically favors single-top training or a light Screen of Green.
Without a published parental pedigree, the best window into Madcap Princess’s lineage is phenotype behavior. Indica-forward lines often exhibit higher myrcene expression, earthy-sweet aromatics, and a rounded body effect, while hybrid influences may add brightness from limonene or spiciness from caryophyllene. Growers who have trialed madcap-type indicas report medium height with a final indoor stretch multiplier of roughly 1.2–1.6x after flip. That ratio supports dense, uniform colas rather than lanky spears.
The cultivar’s indica majority also increases the probability of purpling under cooler night temperatures due to anthocyanin expression. A night temperature differential of 2–4°C during late flower can bring out lilac to violet hues in phenotypes predisposed to color. While color does not guarantee potency or terpene intensity, it correlates with consumer appeal and can improve bag appeal in retail markets. Many growers use this trait strategically for harvest presentation.
In terms of resilience, indica-dominant hybrids often handle moderate abiotic stress better than thin-leaf sativas. Madcap Princess is reportedly tolerant to slightly higher EC during mid flower, provided root zone oxygenation is adequate. This makes the cultivar a good candidate for coco or well-aerated peat mixes where growers target EC 1.8–2.2 in peak bloom. However, its dense bud set requires vigilance against excessive humidity to prevent botrytis.
Appearance and Morphology
Madcap Princess generally develops compact, baseball-to-soda-can sized colas with a high calyx-to-leaf ratio. Buds present as dense and resin-sheathed, with a frostiness that is noticeable even on sugar leaves. Primary coloration ranges from deep forest green to emerald, with phenotypes occasionally showing lavender streaks under cooler conditions. Pistils transition from peach to copper as maturation progresses.
Trichome coverage is a standout feature, with bulbous capitate-stalked trichomes dominating by late flower. Under 60–100x magnification, heads often appear large and well-formed, a trait valued by solventless extractors. Resin density provides the buds with a tacky feel when fresh and a glassy sheen after proper curing. This high-glandular profile contributes to the cultivar’s loud aroma.
Structurally, internodal spacing is tight, typically 3–6 cm on primary branches during early flower. Lateral branching is strong enough to support multiple tops, though trellising or light tomato cages help prevent lodging in weeks 6–8. Leaves are broad with pronounced serration, consistent with its indica-leaning heritage. The canopy tends to form a uniform table under even light distribution.
Growers often remark on the trim-friendly architecture due to prominent calyx stacking. The high calyx ratio can reduce trimming time by 15–30% compared with leafy hybrid cultivars. The finished flowers showcase sharp edges and crystalline surfaces that hold their shape well in jars. This structural integrity helps preserve presentation during transport and storage.
Aroma and Bouquet
Aromatically, Madcap Princess leans toward a rich, multi-layered bouquet with earthy, sweet, and floral overtones. Many indica-dominant selections express myrcene-driven notes reminiscent of ripe plum, damp forest, and tea-like herbality. Secondary accents often include a peppered spice from beta-caryophyllene and a citrus lift from limonene. Together, the nose reads as both soothing and opulent.
Terpene expression is sensitive to environmental variables, and Madcap Princess rewards careful drying. When dried at 60°F/60% RH for 10–14 days, growers routinely report stronger top notes and less terpene burn-off than rapid-dry methods. Under ideal conditions, total terpene content in indica-dominant cultivars typically measures 1.5–3.0% by weight, with exceptional cuts testing above 3%. Slow-curing can preserve a larger fraction of monoterpenes responsible for the top aroma layer.
Some phenotypes reveal a subtle floral-perfume character suggestive of linalool or ocimene influence. This can present as lilac, freesia, or soft rose petal against a deeper earthy base. In others, faint gas or fuel nuances emerge, hinting at terpinolene or humulene interplay even in small percentages. Such complexity is prized by connoisseurs seeking layered aromatics rather than one-note profiles.
Aromatics intensify markedly between weeks 6 and 8 of flowering as monoterpene synthesis peaks. Carbon filtration or sealed environments are recommended in shared spaces due to strong volatility. Growers who defoliate lightly around day 21 often report improved air movement without diminishing terpene density. Overall, Madcap Princess can be categorized as loud, with bouquet strength that stands out in mixed gardens.
Flavor and Mouthfeel
On the palate, Madcap Princess typically delivers a smooth, full-bodied draw with sweet earth and gentle spice leading the profile. The first impression often mirrors the aroma, suggesting a myrcene-caryophyllene backbone with a touch of citrus brightness. Users commonly describe the finish as creamy or tea-like rather than sharp or astringent. This smoothness pairs well with both joints and low-temperature vaporization.
At lower vaporizer temperatures (170–185°C), the cultivar expresses more floral-citrus volatiles, allowing the sweetness to shine. Raising temperature to 190–205°C pulls in deeper herbal and peppered undertones, hinting at caryophyllene’s presence. Combustion retains a surprising amount of flavor when the cure is dialed, but flavor persistence is highest in convection devices. Many consumers report 3–5 distinct flavor pulls before the profile begins to taper.
Mouthfeel is medium-plus in weight, coating the tongue without becoming resinous or cloying. The retrohale can introduce a light eucalyptus or tea-leaf impression, which likely arises from minor terpenes such as eucalyptol or fenchol when present. A properly flushed and cured sample should finish clean, with minimal throat bite even on larger inhalations. This contributes to good sessionability for evening use.
Cannabinoid Profile and Potency
As a mostly indica cultivar bred for modern markets, Madcap Princess is expected to test in the high-teen to mid-20s for THC by dry weight. Public compliance dashboards in multiple legal states commonly show median THC values for indica-dominant hybrids around 19–22%, with top samples exceeding 25%. Madcap Princess, based on grower reports and indica benchmarks, plausibly lands in the 18–26% THC band in well-grown conditions. CBD is generally low in such lines, often below 0.5%.
Total cannabinoids typically track 20–28% for high-performing indica-leaning cultivars when environmental and nutrition parameters are optimized. Grow techniques like CO2 enrichment at 800–1,000 ppm, maintaining PPFD above 900 µmol/m²/s in late flower, and consistent VPD can increase potency by 5–15% relative to suboptimal baselines. However, genetics set the ceiling, and overly aggressive feeding or heat stress can reduce measurable cannabinoids by oxidizing THC or suppressing biosynthesis. Proper post-harvest handling also prevents potency losses from decarboxylation and volatilization.
For consumers, potency is felt not only in mg THC per gram but also in how terpenes modulate the effect. Some users report that 18–20% THC with 2–3% total terpenes can feel stronger than 24% THC with 0.8% total terpenes. This synergy is consistent with observations that terpene ratios influence subjective intensity and onset. Madcap Princess’s terpene-forward profile helps the cultivar punch above its lab number.
When dosing, new users often do well starting with 2.5–5 mg THC via edible or one to two small inhalations. Experienced consumers might prefer 10–20 mg sessions or 2–4 inhalations, spacing them over 10–15 minutes to gauge onset. Inhaled effects typically begin within 5 minutes, peak around 30–45 minutes, and taper over 2–4 hours. Edible onset is slower, at 45–90 minutes, with a duration of 4–8 hours.
Terpene Profile and Chemistry
Although batch-specific testing will vary, indica-dominant cultivars like Madcap Princess commonly show myrcene as a lead terpene in the 0.2–0.8% range by weight. Beta-caryophyllene frequently appears in the 0.1–0.5% range, contributing pepper and a warm spice. Limonene offers brightness, often 0.1–0.4%, enhancing perceived sweetness and uplift. Total terpene content typically consolidates between 1.5–3.0% in optimized grows.
Minor terpenes can shape the profile significantly despite lower concentrations. Linalool, if present at 0.05–0.2%, can impart floral and lavender notes while potentially enhancing relaxation. Humulene in the 0.05–0.2% range can add woody, herbal bitterness that balances sweetness. Trace ocimene or terpinolene may appear, showing bright floral-citrus facets even below 0.05%.
From a biochemical perspective, terpene synthesis ramps in mid to late flower as glandular trichomes mature. Heat, light intensity, and humidity exert strong control on terpene retention; excessive heat above 28–29°C in late flower can volatilize monoterpenes and reduce top-note intensity by measurable margins. Drying at 60°F/60% RH has become a best-practice target because it slows water loss enough to protect volatile fractions. After two weeks, a stable water activity around 0.58–0.62 supports long-term aroma preservation.
Madcap Princess’s terpene balance makes it adaptable to multiple consumption methods. Low-temperature dabs of rosin preserve monoterpenes that define the strain’s floral and citrus edges. Convection vaporization at 180–190°C will emphasize limonene and linalool, while combustion will tilt toward caryophyllene and humulene. This versatility helps the cultivar appeal to both casual and connoisseur consumers.
Experiential Effects and Onset
With a mostly indica heritage, Madcap Princess is widely described as relaxing, body-centric, and calming without being overwhelmingly sedative at moderate doses. Early effects include a loosening of physical tension and a warm, mood-lifting euphoria. Many users report a transition from mental chatter to a steady, grounded focus suitable for low-stress activities. The experience often pairs well with evening routines, creative contemplation, or winding down after work.
Onset after inhalation typically begins within 3–5 minutes, with peak intensity around 30–45 minutes. The body effect builds steadily, with a gentle weight behind the eyes and shoulders that signals a shift toward relaxation. At higher doses, couchlock becomes more likely, especially in low-stimulus environments. Duration usually spans 2–4 hours for inhaled use, depending on tolerance and concurrent food intake.
Adverse effects are generally mild but can include dry mouth and dry eyes, reported by a significant proportion of consumers across indica-dominant cultivars. Occasional dizziness or orthostatic lightheadedness can occur, especially when standing quickly or in dehydrated users. Anxiety is less commonly reported with indica-leaning strains than with racy sativas, but very high THC doses can still precipitate it in susceptible individuals. Titration and mindful set-and-setting help limit unwanted effects.
Many consumers highlight improved sleep latency when Madcap Princess is consumed 1–2 hours before bedtime. Relaxation tends to be full-body without mental fogginess at modest doses, making it useful for evening socializing or low-key activities. Those seeking deep sedation can increase dose slightly or pair with a calming environment and screen-time reduction. The consistent, predictable effect curve is part of the cultivar’s appeal.
Potential Medical Uses and Considerations
Patients often reach for indica-dominant cultivars like Madcap Princess to address pain, stress, and sleep disturbances. User reports commonly note reductions in perceived musculoskeletal discomfort and an easing of anxiety or rumination. The body-centric relaxation can also help with post-exercise recovery and muscle tightness. While individual responses vary, these patterns align with typical indica-forward outcomes.
Evidence reviews have found substantial support for cannabis in chronic pain management and chemotherapy-induced nausea, with more mixed results in other domains. THC-dominant profiles can reduce pain intensity scores by clinically meaningful margins in some patients, though side effects and tolerance must be considered. Terpenes such as myrcene and linalool may add complementary calming effects, potentially aiding sleep initiation. Madcap Princess’s expected terpene balance supports these use cases.
For sleep, patients often report improved sleep latency and fewer nighttime awakenings when dosing 30–90 minutes before bed. As with all THC-forward products, higher doses can produce next-day grogginess for some individuals. Starting with a low dose and slowly titrating supports therapeutic benefits while minimizing impairment. Consistent routines and sleep hygiene practices amplify the strain’s sedative potential.
Patients with anxiety should start conservatively because THC can be bidirectional for mood. Many find relief at low to moderate doses, especially when accompanied by calming terpenes like linalool and beta-caryophyllene. Those with cardiovascular concerns should be aware that THC can transiently elevate heart rate by 20–30 bpm. Consulting a clinician familiar with cannabinoid medicine is recommended for personalized guidance.
Cultivation Guide: Planting, Vegetative Growth, and Training
Madcap Princess performs well in soil, coco, or hydroponic systems, with coco-perlite mixes offering fast growth and precise nutrient control. Germination typically occurs within 24–72 hours using a moist paper towel or directly in starter cubes at 24–26°C. Seedlings prefer gentle light at 200–300 PPFD and a root-zone pH of 5.8–6.0 in inert media or 6.2–6.5 in soil. Aim for 65–70% RH during the first week to encourage rapid root establishment.
Vegetative growth is vigorous yet compact, making the strain responsive to topping and low-stress training. A veg phase of 3–5 weeks under 18/6 or 20/4 photoperiod typically produces robust plants ready for flowering. Maintain 24–27°C during lights-on, 22–24°C lights-off, and RH around 55–65%. PPFD in veg can ramp from 300 to 500–600 µmol/m²/s as plants mature.
Nutritionally, target an N-P-K balance near 3-1-2 in mid veg with 150–200 ppm calcium and 40–60 ppm magnesium. Keep EC around 1.2–1.6 and ensure 10–20% runoff in soilless systems to prevent salt buildup. Silica at 50–100 ppm can strengthen cell walls and improve stress tolerance. Foliar feeds should be light and discontinued by late veg to reduce disease risk.
Training strategies include topping at the 4th–6th node followed by LST to spread the canopy. Madcap Princess responds well to a single-layer SCROG, filling a 2x2 ft area with one plant in 4–5 weeks of veg. Internodal spacing remains tight, so selective pruning of inner growth improves airflow. Avoid over-defoliation; remove only leaves that shade future tops.
Transplant to final containers 7–10 days before flipping to flower to minimize post-flip stress. Fabric pots of 3–5 gallons for indoor runs balance root volume and irrigation frequency. In high-intensity setups, automated drip irrigation with multiple daily pulses can maintain optimal root oxygen. Monitor VPD in veg around 0.8–1.2 kPa for best growth.
Cultivation Guide: Flowering, Environment, and Nutrition
When transitioning to flower, expect a manageable stretch with a 1.2–1.6x height increase over the first three weeks. Set day temperatures at 22–26°C and nights 2–3°C cooler to preserve monoterpenes. Maintain RH at 50–55% in early flower, reducing to 42–48% by late flower to mitigate botrytis risk. PPFD can rise to 700–900 µmol/m²/s in weeks 1–4, then 900–1,100 µmol/m²/s in weeks 5–8 if CO2 is supplemented.
Nutrient strategy should shift to 1-2-2 in early flower and 1-2-3 in mid flower, with careful attention to potassium for bud development. Keep EC near 1.7–2.2 during peak bloom depending on substrate and cultivar response. Maintain pH at 5.8–6.0 in coco or hydro and 6.3–6.7 in soil. By weeks 7–8, gradually reduce nitrogen to enhance burn quality and color expression.
Canopy management focuses on even light distribution and airflow across dense colas. A light defoliation around day 21 of flower removes large fan leaves obstructing bud sites, followed by a second clean-up around day 42 if needed. Gentle trellising prevents branch flop as flowers densify. Aim for horizontal canopy uniformity to keep PPFD within ±10% across tops.
Water management is critical because indica-dominant flowers hold more moisture within dense calyx clusters. In soilless media, multiple small irrigations each day help maintain stable EC and oxygen levels, reducing the risk of hypoxic roots. In soil, allow modest drybacks between waterings while avoiding full wilting. Monitor runoff EC to keep salt accumulation in check.
A typical indoor harvest window for Madcap Princess falls between day 56 and day 63. Trichome inspection is the best guide: many growers target 5–10% amber, 80–90% cloudy for a balanced effect. If heavy sedation is desired, waiting for 15–20% amber is common at the cost of some brightness. Track aroma shifts; a peak in floral-sweet notes often coincides with optimal ripeness.
Cultivation Guide: Integrated Pest Management and Disease Prevention
Dense indica flowers can be susceptible to powdery mildew and botrytis in high humidity, making prevention crucial. Keep leaf surface airflow around 0.3–0.5 m/s with oscillating fans and ensure clean intakes. Sanitize tools and surfaces between tasks and avoid working on plants when leaves are wet. Canopy thinning to remove interior larf reduces microclimates where pathogens thrive.
A layered IPM program is recommended, blending cultural, biological, and minimal chemical inputs. Biologicals like Beauveria bassiana and Bacillus subtilis can be rotated to suppress common foliar pests and fungi. Predatory mites such as Phytoseiulus persimilis and Amblyseius swirskii target spider mites and thrips, respectively. Introduce beneficials early in veg or at the very onset of flower for best results.
Root health is foundational for disease resistance, especially in coco or hydro where pythium pressure can spike. Maintain dissolved oxygen with frequent irrigations and avoid reservoir temperatures above 20–21°C. Add beneficial microbes or enzymes to limit biofilm and promote root vigor. Ensure excellent drainage and avoid standing water in saucers.
If chemical interventions are needed, choose options labeled for edible crops and observe pre-harvest intervals strictly. Avoid sulfur after early flower because residues can compromise terpene expression and clash with oils. Always test new inputs on a small subset of plants before broad application. Records of interventions help diagnose future issues and refine the program.
Harvest, Drying, Curing, and Storage
Harvest timing has an outsized influence on flavor and effect. For a balanced euphoric-relaxing profile, many growers cut at 5–10% amber trichomes when the majority are cloudy. For heavier sedation, waiting until 15–20% amber is common, though terpene brightness may fade slightly. Use clean shears and minimize rough handling to preserve trichome heads.
Drying targets of 60°F (15.5°C) and 60% RH for 10–14 days are widely adopted to protect volatile monoterpenes. Gentle air movement below 0.5 m/s prevents mold without desiccating outer tissues too quickly. Stems should snap rather than bend before moving buds into cure. Slow drying can retain 70–85% of terpene content compared to rapid drying that can chop this by half or more.
Curing in airtight glass jars at 58–62% RH for 3–8 weeks polishes the aroma and smooths the smoke. Burp jars daily during the first week, then every 2–3 days, monitoring for even moisture distribution. A stable water activity of 0.58–0.62 supports long-term storage without microbial risk. Flavor complexity typically peaks around week 4–6 of cure.
For storage, keep jars in a dark space at 16–20°C, avoiding temperature swings that accelerate oxidation. Light and heat can degrade cannabinoids and terpenes, with THC slowly converting to CBN over time. Under proper storage, potency and aroma remain robust for 6–12 months, with gradual decline after. Vacuum-sealed, cool storage can extend longevity further for personal reserves.
Breeder and Market Notes for 2 Guns and a Guy Seed Company
2 Guns and a Guy Seed Company positions Madcap Princess squarely within the modern indica-leaning niche. The breeder’s emphasis on resin density, compact structure, and cure-friendly bud architecture aligns with current consumer preferences. In many markets, indica-dominant cultivars account for a significant share of sales, often over 40% depending on region and season. Madcap Princess’s approachable effects and strong bag appeal place it well within that demand.
For growers, the cultivar’s moderate bloom time and manageable stretch make it suitable for 8–9 week production cycles. Indoor yields for indica-dominant plants commonly range 400–550 g/m² under optimized LED lighting at 700–1,000 µmol/m²/s. Outdoors in favorable climates, plants can produce 500–900 g per plant with adequate root volume and disease control. Consistency across runs improves profit predictability in small-scale commercial rooms.
Because the exact lineage is undisclosed, marketing focuses on sensory experience and reliability rather than pedigree hype. Retail buyers respond to clear, accurate descriptors—“floral-earthy sweet,” “soothing, body-forward relaxation,” “56–63 day finish”—that set expectations. Samples cured properly at 62% RH with intact trichome coverage tend to move quickly. Batch COAs that show 20%+ THC with 2%+ terpenes are competitive in most adult-use markets.
For hash makers, test-washing small batches is advisable to evaluate wash yields and micron distribution. Indica-dominant resin often favors 90–120 µm bags, though distribution can vary by phenotype and ripeness. While not all phenotypes will be solventless standouts, the strain’s visible glandular density merits exploration. Selection of a keeper mother can markedly improve post-harvest performance across future cycles.
