Bob 87 by Purple City Genetics: A Comprehensive Strain Guide

Origins and Overview

Bob 87 is a mostly sativa cultivar developed by the innovative breeders at Purple City Genetics, a California outfit known for forward-looking selections and terpene-driven hybrids. As a sativa-leaning selection, Bob 87 aims to deliver clarity, energy, and a high-ceiling buzz without sacrificing modern resin density or bag appeal. While still a relatively boutique release, it has gained attention among connoisseurs who chase lively daytime profiles and growers who favor vigorous, upright plants.

Because Bob 87 is not yet a household name like trend-defining classics, it sits in the exciting frontier between underground favorite and next-wave staple. In a market where high-THC, terpene-expressive sativas are scarcer than heavy indica crosses, Bob 87 fills a welcome niche. The result is a cultivar positioned to satisfy both flavor-focused consumers and production-minded cultivators.

Purple City Genetics emphasizes phenotype exploration and selection, so Bob 87 may express subtly different aromas and effects depending on cut and conditions. This phenotype-driven approach matches how many contemporary breeders iterate, refining releases with field feedback. For consumers, that means paying attention to batch-specific test data and trusted sources to ensure you’re getting the Bob 87 expression you expect.

History and Breeding Background

Purple City Genetics (PCG) has built a reputation for finding heady, grower-friendly plants that thrive in real-world conditions. Their catalog frequently emphasizes nuanced terpene profiles, impressive resin production, and vigorous structure suited to both indoor canopies and controlled-environment greenhouses. Bob 87 fits the PCG ethos: modern, expressive, and tuned for sensory appeal without losing agronomic practicality.

The precise parental lineup of Bob 87 has not been publicly disclosed as of the latest reports, a common practice among elite breeders protecting proprietary lines. What PCG has signaled is its mostly sativa heritage, which guides expectations for taller internodes, soaring effects, and an emphasis on fresh, bright aromatics. The secrecy around lineage can be a feature, encouraging growers and consumers to evaluate the plant on performance and flavor first.

Bob 87 likely emerged from a multi-generational selection process that winnowed vigorous, upright individuals with clean, uplifting highs and a terpene bouquet biased toward bright, herbal, or citrus-adjacent notes. As with many PCG projects, stability is pursued through testing across different environments and dialing in a keeper cut. This iterative model has helped PCG cultivars build cult followings among California’s discerning scene and beyond.

Genetic Lineage and Heritage

The breeder identifies Bob 87 as mostly sativa, which sets expectations for both morphology and experiential effects. Sativa-leaning cultivars commonly exhibit longer flowering windows, narrower leaflets in veg, and a tendency toward taller, candle-like colas. On the effects side, they often deliver mental lift, creativity, and focus, particularly at moderate doses.

Because the exact parents aren’t disclosed, inferential comparisons rely on broader sativa patterns seen across contemporary markets. For example, many modern sativa-leaners express terpene dominance in myrcene, pinene, or terpinolene, sometimes rounded by caryophyllene or limonene. Leafly’s editorial overview of energizing strains for activity highlights profiles with myrcene followed by pinene and caryophyllene as particularly zesty, a pattern Bob 87 growers may find echoed depending on the cut and conditions.

In today’s gene pool, sativa heritage also correlates with robust vigor and apical dominance—traits prized when training screens or managing vertical space. From a breeding standpoint, PCG’s curation suggests they selected for a trim-friendly calyx-to-leaf ratio and resinous flower sets without gassy monotony. The upshot is a sativa-forward plant that remains practical in mixed gardens and attractive for post-harvest processing.

Appearance and Plant Morphology

Bob 87 typically presents as an upright, apically dominant plant with mid-length internodes that stretch moderately in early bloom. Expect spear-shaped colas with stacked calyxes and a glistening trichome coat that announces potency and terp richness. Leaflets lean narrow to medium-narrow, consistent with its mostly sativa heritage.

Coloration generally stays lime to medium forest green, darkening slightly as phosphorus intake ramps in mid-flower. Cooler night temperatures toward late bloom (ideally a 10–12°F differential) can tease out faint anthocyanin blushes on some phenotypes, though full-on purple is not the norm. Sugar leaves tend to be modest, reducing trimming time and improving bag appeal right off the line.

Under high-intensity LEDs (700–1000 µmol/m²/s in flower), Bob 87 can pack on dense but not rock-hard flowers, resisting the overcompression sometimes seen in indica-leaning lines. In high heat, a light foxtail at the tips may occur, a common sativa response that can be minimized with tight environmental control. Resin heads are usually bulbous and abundant, supporting both full-flower sales and solventless extraction experiments.

Aroma and Bouquet

Bob 87’s bouquet sits in the bright, invigorating half of the spectrum, with herbal, piney, and faintly citrus or sweet top notes. On dry pull, many tasters report a breezy conifer snap layered over fresh-cut herbs and a whisper of floral sweetness. Beneath that, a peppery backbone hints at caryophyllene, lending a grounding warmth to the nose.

The aroma opens as flowers cure, intensifying during weeks 2–4 in the jar as chlorophyll fades and terpenes stabilize. Gentle burping and 62% humidity packs help preserve the high-volatility monoterpenes that drive Bob 87’s first impressions. Expect the scent profile to project confidently when ground, with a clean, breathable character that avoids cloying heaviness.

Notably, sativa-leaning profiles with pinene and myrcene resonance often read as forest-fresh and slightly sweet—paralleling Leafly’s hiking-friendly picks that emphasize gusty, palate-waking terpenes. If your cut leans more toward limonene, a spritzy citrus twist may sit atop the herbal core. Either way, Bob 87’s nose tends to communicate ‘daytime’ from first whiff.

Flavor and Combustion Characteristics

Flavor tracks the aroma closely: brisk pine and garden-fresh herbs lead, with a satin sweetness that lingers on the exhale. Vaporizing at 180–190°C (356–374°F) highlights the terpene lift while muting harsher phenolics, yielding a minty-forest finish for many users. Combustion at lower temps in cones or glass preserves brightness and holds the flavor line deeper into the session.

As cure progresses, pepper-spice undertones typically round the profile, pointing to caryophyllene’s culinary warmth. Terp-heavy sativa-leaners can sometimes flash a faint floral or tea-like note when vaped at 170–175°C (338–347°F), a pleasant dimension for connoisseurs. Proper moisture content (10–12%) supports even burn and a clean ash, showcasing the cultivar’s elegant palate.

When paired with fruit-forward papers or unflavored hemp wraps, Bob 87’s pine-herb core remains dominant, cutting through with clarity. Glass water filtration at modest percolation preserves nuance while reducing throat bite for sensitive consumers. Overall, this is a flavor profile built for repeat pulls rather than a one-and-done novelty hit.

Cannabinoid Profile and Potency

As a modern, mostly sativa release, Bob 87 slots into the contemporary potency band common to premium flower. Lab-tested sativa-leaners routinely arrive between 18–26% total THC (reported as THCa pre-decarboxylation plus estimated delta-9 THC), with CBD typically under 1%. Minor cannabinoids like CBG often land in the 0.3–1.5% range, adding entourage complexity even at low absolute levels.

Without published, widely replicated COAs specific to Bob 87 across markets, it’s prudent to treat individual batch results as authoritative for that lot. Grower technique, harvest timing, and post-harvest handling can swing potency several percentage points. For example, delayed harvest by 7–10 days can push THCa up but risk terpene attrition, while poor drying can degrade monoterpenes and oxidize cannabinoids.

For dosing expectations, inhaled onset generally appears within 1–5 minutes, with peak effects around 15–30 minutes and a 1.5–3 hour duration for most users. Edible conversions using Bob 87’s decarbed flower or concentrates have a slower onset (30–120 minutes) and longer duration (4–8 hours), reflecting first-pass metabolism. If producing edibles, target decarb at ~115°C/240°F for 35–45 minutes to maximize THCa to THC conversion while limiting terp loss.

Minor cannabinoid presence can subtly modulate the experience. CBG in the 0.5–1% band is frequently associated with a tempered, less anxious high in some users, though responses vary. Trace CBC and THCV—when present—may add alertness or appetite modulation, but only lab data on a per-batch basis can confirm meaningful levels.

Terpene Profile in Detail

Sativa-forward plants like Bob 87 often center on monoterpenes that smell fresh, bright, and breathable. In many energizing profiles, myrcene appears in moderation with pinene close behind, and caryophyllene adding peppered warmth. Leafly’s spotlight on stimulating strains for hiking calls out a myrcene-first, pinene-second, caryophyllene-third pattern that ‘blasts’ taste buds with sweet-herbal intensity, a useful reference point when assessing Bob 87 phenotypes.

It’s common to see these cores complemented by a slice of limonene, sharpening citrus lift and adding perceived ‘mood elevation.’ For comparison, widely distributed cultivars like GMO are often tested with caryophyllene, limonene, and myrcene as dominant terpenes—a trio that brings spicy-sweet depth while keeping the nose expressive. Bob 87 may echo aspects of that balance but pushes more toward the airy, pine-herb side than GMO’s savory-funk signature.

Quantitatively, many premium sativa-leaners test at total terpene content between 1.5–3.0% by weight under optimized cultivation and careful curing. Within that, pinene fractions of 0.2–0.6% are not unusual for pine-forward noses, while myrcene often spans 0.4–1.0% depending on cut and maturity. Caryophyllene commonly inhabits the 0.2–0.5% window in such profiles, contributing body without heavy musk.

Growers should note that terpene expression is highly plastic: light intensity, spectrum balance, root-zone health, and even harvest time within a 7–10 day window can shift dominance. Warmer late flower can volatilize monoterpenes, nudging the mix toward sesquiterpenes and altering perceived flavor. Accurate terpene readouts require fresh, representative sampling and a competent lab—always check COAs if you need certainty.

Experiential Effects and Use Scenarios

Bob 87’s effects skew uplifting, clear, and gently euphoric, with a functional buzz that encourages conversation and creative work. At lower to moderate doses, users often report enhanced focus and a clean body feel without lethargy. As dosage increases, the high can arc toward classic sativa cerebral intensity—invigorating for some, racy for others.

The cultivar’s likely pinene-caryophyllene support may contribute to a ‘fresh air’ mental state with grounded edges. When vaporized, many users describe a crisp onset and a steady, plateauing ride rather than a steep peak-and-crash. Music, design tasks, trail walks, and social gatherings are common pairings where Bob 87 shines.

Set and setting remain crucial. Sensitive users or those with anxiety-prone physiology may prefer microdoses (one or two small inhalations) to enjoy clarity without jitters. Hydration, a light snack, and a calm environment help shape a comfortable, productive session, especially for daytime use.

Potential Medical Applications

Although individual responses vary and medical use should follow clinician guidance, Bob 87’s sativa-leaning profile suggests several plausible therapeutic niches. Daytime mood support, fatigue-related motivation, and focus enhancement are frequent targets for bright terpene-forward cultivars. Inhaled onset speed can be useful for situational symptoms like acute stress or low energy.

Mechanistically, key terpenes in this family carry supportive literature. Beta-caryophyllene is a known CB2 agonist that may help modulate inflammation and nociception, making it of interest for pain-associated conditions without intoxicating anxiety. Alpha- and beta-pinene are studied for bronchodilatory effects and potential memory-supportive properties, while myrcene is frequently associated with muscle relaxation and analgesia at higher doses.

For appetite and GI discomfort, many sativa-leaners provide mild to moderate relief without the heavy sedation sometimes seen in indica-dominant profiles. Patients sensitive to THC-induced anxiety should approach cautiously, titrating in small steps and considering balanced CBD adjuncts. Always consult lab results—terpene and minor cannabinoid composition can tilt experiences meaningfully between batches.

Comprehensive Cultivation Guide

Bob 87 responds well to contemporary controlled-environment methods, thriving under full-spectrum LEDs or high-efficiency HPS with attentive training. Aim for vegetative temperatures of 74–80°F (23–27°C) and relative humidity (RH) of 55–65%, tapering to 68–78°F (20–26°C) and 40–50% RH in late flower to suppress botrytis risk. Maintain VPD in the 0.9–1.2 kPa range in veg and 1.2–1.5 kPa in bloom for steady transpiration and nutrient flow.

Light intensity targets of 350–500 µmol/m²/s in veg and 700–900 µmol/m²/s in flower are a good starting range for most phenotypes, scaling up carefully to 1000 µmol/m²/s if CO2 is enriched (900–1200 ppm). Soil pH should sit around 6.2–6.8; for coco/hydro, 5.7–6.1 helps preserve micronutrient availability. In coco, start EC around 1.2 in early veg and incrementally rise to 1.8–2.2 in peak bloom depending on plant hunger and runoff readings.

Training and canopy management: Top once at the 4th–5th node, then implement low-stress training (LST) to open the plant and discourage runaway apical dominance. A single-layer SCROG at 8–12 inches above the pot rim helps even the canopy, with a 20–30% defoliation around day 21 and 42 of bloom to improve airflow and light penetration. Sativa-leaners like Bob 87 often stretch 1.5–2x; flip to flower when plants reach 50–60% of your target height.

Nutrition: Keep nitrogen robust in early veg, then shift toward phosphorus and potassium emphasis as preflower pistils appear. Calcium and magnesium supplementation (e.g., 100–150 ppm Ca and 40–60 ppm Mg net in coco/hydro) helps maintain cell wall integrity under high-intensity light. Monitor leaf tissue: clawing suggests excess N, interveinal chlorosis can flag Mg shortage, and rust spots point to Ca or K issues.

Watering: In soil, water to 10–20% runoff when the top inch is dry; in coco, higher frequency, lower volume irrigations support oxygenation and prevent salt buildup. Keep root zone temperatures 68–72°F (20–22°C) to maximize nutrient uptake and stave off pathogens. Use beneficial microbes or enzymes to keep the rhizosphere active and reduce dead root mass accumulation.

Integrated Pest Management (IPM): Implement a preventive schedule—weekly scouting, sticky cards, and leaf underside inspections. Predatory mites (e.g., Amblyseius swirskii, A. andersoni) are helpful against broad-spectrum pests; rotate contact and systemic bio-fungicides during veg to keep mildew pressure low. Good canopy spacing, negative-to-positive pressure balance, and HEPA intake filtration further reduce infestations.

Flowering time and harvest: Mostly sativa cultivars commonly finish in 9–11 weeks from flip, though actual maturity depends on phenotype and environment. Rather than relying on breeder targets alone, watch trichomes—harvest at ~5–10% amber, 80–90% cloudy for a brighter effect profile; pushing to 15–20% amber nudges sedation. Staggered harvests across top/mid colas can optimize ripeness on larger plants.

Greenhouse strategy: As Dutch Passion’s greenhouse guidance notes, protected cultivation is a secure, productive route for home growers, blending sun power with environmental control. Use light-dep to enforce 12/12 for precise flowering windows and hang shade cloth to buffer midsummer heat and terp volatilization. Seal entrances with insect netting, manage humidity with roll-up sides and circulation fans, and monitor leaf surface temperature—terpenes reward finesse.

Seed, clone, and sexing considerations: If Bob 87 is available as seed, feminized lots can simplify planning by producing predominantly female plants; Dutch Passion popularized feminized seeds in the 1990s, and the approach remains industry standard for reliability. If working from regular seed, sex early using preflower cues or send tissue samples for rapid sex testing. Clones from a verified keeper cut offer the most phenotypic consistency, a major advantage when dialing SOPs.

Yield expectations: With a well-filled 4x4 ft canopy under 500–650 watts of efficient LED, 1.0–1.5 grams per watt is attainable for dialed-in growers, translating to roughly 18–35 grams per square foot per week of flowering over a 9–10 week run. Sativa-leaners can surpass these marks with aggressive training and CO2 enrichment, but they also punish environmental drift by foxtailing or stalling. In greenhouse beds, season length and root volume can push yields substantially higher while preserving terp intensity.

Post-harvest: Dry at 60°F/60% RH for 10–14 days in the dark with good airflow but no direct breeze on flowers. Aim for a slow, even dry to preserve monoterpenes, then cure at 58–62% RH for 3–6 weeks, burping jars or using breathable curing vessels. A proper cure not only polishes Bob 87’s pine-herb brightness but also smooths the mouthfeel and extends shelf life.

Autoflower and comparative context: While Bob 87 is typically approached as a photoperiod sativa-leaner, know that modern autos can achieve formidable potency—autos like Quarter Pounder often exceed 20% THC, and Big Bud Autoflower is listed around 23% THC in some seed catalogs. If a Bob 87 auto variant ever appears, it can be run on 18/6 light from seed to finish with careful nutrition to match its vigor. Until then, photoperiod plants remain the surest path to the cultivar’s full expression.

Consumption Methods, Dosing, and Onset

Inhalation (flower or concentrate) remains the most precise way to experience Bob 87’s terpene profile. Onset typically begins within 1–5 minutes, with peak effects near 15–30 minutes and a 1.5–3 hour tail, depending on dose and tolerance. Microdosing—one or two modest puffs—delivers a functional, clear uplift suitable for work or daytime errands.

Vaporization at controlled temperatures allows fine-grained flavor exploration and dose titration, reducing combustion byproducts. Dabbing live resin or rosin extracts of Bob 87 amplifies terpene intensity and psychoactivity; start under 15–20 mg THC-equivalent per session if you’re not extract-experienced. For portable discretion, low-temp cartridges can approximate the cultivar’s vibe, though some nuance is lost compared to fresh flower.

Oral routes offer longer duration with a delayed onset. Leafly has noted that gummies and other discreet edibles dominate preference in hemp-based product formats, a trend that spills over into the broader cannabis space due to convenience and dosing clarity. If infusing with Bob 87, dose conservatively—2.5–5 mg THC for newer users, 5–10 mg for intermediates—and allow a full 2 hours before redosing to avoid stacking.

Market Context and Availability

Bob 87 competes in a market that churns rapidly through hype cycles while steadily rewarding cultivars with repeatable effects and distinctive flavor. Editorial roundups like Leafly’s ‘100 best weed strains of 2025’ underscore the breadth of consumer tastes and the value of clearly expressed terpene identities. Within that landscape, a bright, pine-herb sativa-leaner carries strong daytime appeal for both medical and adult-use customers.

Distribution for breeder-driven cuts often begins regionally, then scales via licensed nurseries and partner cultivators if demand holds. If you’re shopping, look for COAs that confirm total THC in the high teens to mid-20s and terpene totals above 1.5% for the most expressive lots. Transparency on harvest date, cure conditions, and storage adds confidence—freshness matters for volatile, pine-forward noses.

For growers, availability may cycle between clone-only drops and limited seed releases depending on PCG’s program cadence. When seeds are offered, feminized options simplify canopy planning and reduce wasted veg space from male culls. Whether you’re a consumer or cultivator, lean on reputable shops and nurseries to ensure you’re getting authentic Bob 87 rather than a near-miss substitute.
