Auto White Prussian traces its roots to Europe’s fast-maturing seed movement of the late 2000s and early 2010s, when growers demanded compact, resilient plants with respectable potency. Bulk Seed Bank, the breeder of this cultivar, responded by adapting one of its resin-forward “white” hybrids into an autoflowering format. The result is a deliberately balanced ruderalis/indica/sativa cross that finishes in weeks rather than months, aligning with short-season and indoor demands. While Bulk Seed Bank markets widely, the ethos is consistent: stable, high-volume seed production with predictable traits.
The “Auto” tag denotes the inclusion of Cannabis ruderalis genetics, which shifts photoperiod dependence to age-based flowering. This change was pivotal for northern-latitude cultivators who contend with cool nights and compressed summers. Between 2010 and 2020, autoflowering varieties grew from niche to mainstream, with commercial reports indicating autos now account for a substantial share of hobby grow sales in the EU and North America. Auto White Prussian fits squarely into that trend, providing a fast finish with a classic European flavor profile.
The “White” in the name reflects the heavy trichome coverage associated with heredities like White Widow and other frost-dominant hybrids. Although the specific photoperiod parents behind Bulk Seed Bank’s White Prussian line are not publicly detailed by the breeder, the phenotype echoes popular 1990s Dutch breeding hallmarks: dense resin, bright uplift, and manageable stature. Converting such a line to auto typically involves several generations of crossing and backcrossing to a ruderalis donor. Breeders usually stabilize in F4–F6 generations to reduce phenotype drift and lock in autoflower timing.
Market demand sharpened the selection criteria for Auto White Prussian: fast finish, indoor adaptability, and strong bag appeal. Growers sought plants that could complete a full cycle in 9–12 weeks from sprout while retaining mid-to-high potency potential. Bulk Seed Bank’s catalog placement underscores those expectations, coding it as a balanced hybrid suited to a wide range of environments. As a result, Auto White Prussian became a practical option for discreet balconies, micro-tents, and multi-run annual schedules.
Over time, community growers have reported that the line maintains its auto onset even under 20–24 hours of light per day, which is a hallmark of consistent ruderalis expression. The stability is meaningful: inconsistent autos may stall or flip unpredictably, complicating tent management. Auto White Prussian’s regularity allows synced multi-plant runs and staggered harvests without changing the light schedule. This reliability has helped the strain gain a steady following in mixed-experience grower circles.
Genetic Lineage and Heritage
Bulk Seed Bank lists Auto White Prussian with a ruderalis/indica/sativa makeup, reflecting its hybridized autoflowering design. The ruderalis component imparts photoperiod independence and improved cold tolerance, while the indica heritage drives density, resin, and a grounded body effect. Sativa influence expresses in the cultivar’s reported mental clarity and heady uplift during the first phase of the experience. In practice, phenotype expression can lean slightly indica in structure while still delivering a mentally bright top note.
Although Bulk Seed Bank has not publicly released a precise parentage list, the “White” moniker and resin-forward phenotype strongly suggest a lineage influenced by classic white resin families popularized in the Netherlands. Community reports often associate the “Prussian” hint with a nod to old-school European hybrid vigor and a bright, pine-citrus accent in the terpene mix. Such naming patterns are common in seed branding to evoke recognizable effects and flavors. Regardless of exact pedigree, the functional outcome is a balanced hybrid with a modern auto clock.
Ruderalis alleles typically reduce total plant size and accelerate the transition to flower, often within 21–28 days from emergence. That means growers can expect a predetermined lifecycle that is less sensitive to interruptions in the light cycle. Because autos cannot be “vegged longer” by changing light schedules, the base photoperiod parent must be chosen for early vigor and compact architecture. Auto White Prussian fits that mold, tending toward a medium height and manageable internode spacing.
When breeders convert a photoperiod line to auto, they generally require several generations to recover terpene density and cannabinoid potential. Early autos from the 2000s sometimes lagged behind in potency, but modern autos routinely hit mid-teens to low-20s THC under competent cultivation. Auto White Prussian belongs to this more advanced generation of autos, balancing speed and potency more effectively than earlier waves. Stabilization also reduces outliers that finish too early or too late.
Genetic diversity among seed lots is normal in autos, yet reports indicate Auto White Prussian shows reasonably tight flowering windows. Many growers see initial pistils in week 3–4 and harvest by week 9–11 from sprout. This range reflects the ruderalis trigger coupled with indica/sativa growth dynamics. Minor deviations often trace back to environmental variables like root zone health, light intensity, and nutrition, rather than genetic inconsistency alone.
Appearance and Morphology
Auto White Prussian typically forms a compact to medium frame, often 50–90 cm (20–35 inches) indoors, depending on pot size and light intensity. The apical cola tends to dominate, with side branches forming satellite florets that can be shaped via gentle low-stress training (LST). Internode spacing is moderate, which helps buds stack without excessive larf. The overall stance is tidy and symmetrical when started in final containers.
Leaves are medium-broad with a healthy green hue that can lighten slightly in high-intensity light or near harvest. Indica influence shows in leaf breadth, while sativa heritage keeps petioles firm and blades not overly squat. In cooler nights near finishing, some phenotypes express subtle lime-to-olive gradients rather than dramatic purples. The aesthetic is more “frost-over-green” than colorful.
Trichome coverage is a defining feature, often coating calyxes and small sugar leaves with a visible white sheen. Under magnification, stalked glandular trichomes with bulbous heads dominate, which is typical for high-resin hybrids. The dense frost contributes to the “white” naming convention and is closely linked to aroma intensity and perceived potency. Well-grown specimens can look sugar-dusted even before final swell.
Bud structure leans toward tight, resinous clusters with a favorable calyx-to-leaf ratio. This improves post-harvest trimming efficiency and increases bag appeal. Mature colas can be surprisingly firm for an auto, especially when environmental controls keep vapor pressure deficit (VPD) around 1.0–1.2 kPa in mid-flower. Support stakes or soft ties may be helpful if flowers put on quick weight.
Root systems in autos benefit from early, unobstructed expansion, and Auto White Prussian is no exception. When given 11–18 L (3–5 gal) final containers from day one, this cultivar typically establishes a strong taproot and lateral network within two weeks. The robust root zone supports steady vertical growth through the preflower window. Transplanting is best avoided or done extremely early to prevent stall.
Aroma Profile
The aroma of Auto White Prussian is classic and assertive without being overly pungent, often opening with a citrus-pine top note. Many growers describe bright lemon-lime flashes supported by fresh sawdust or pine resin. Beneath that sits an herbal base—bay leaf, sweet basil, or green tea—interlaced with peppery spice. A subtle earthy sweetness rounds out the bouquet at maturity.
During late flower, the nose deepens, and the woodsy elements become more pronounced. Caryophyllene-driven spice may come forward when buds are gently agitated, releasing pepper and clove highlights. Myrcene contributes a faint mango-earth undertone that reads as “soft fruit” rather than overtly tropical. In rooms with strong airflow, the scent can carry a few meters, so carbon filtration is recommended.
Drying captures a slightly different register, with monoterpenes like limonene and pinene evaporating more readily if conditions are too warm or too dry. At 60°F/60% RH (15.5°C/60% RH), many growers report better preservation of the lemon-pine zest. If dried faster at high heat or low humidity, the aroma leans woody and peppery at the expense of bright citrus. A careful cure restores complexity, revealing herbal sweetness after two to four weeks in jars.
Once cured, cracked buds release a layered aroma that toggles between citrus zest, pine needles, and a peppered herbal tea. Some phenotypes hint at eucalyptus or menthol, which commonly correlates with alpha- and beta-pinene content. Others keep to a rounded spice-fruit profile with less perceived sharpness. These small variations are typical for autos with hybrid lineage.
Aroma intensity is moderate to high when handled, but moderate when static in a jar. Total terpene concentration in balanced autos commonly falls in the 1.2–2.2% by dry weight range under good cultivation. While actual lab values vary, the sensory profile suggests a distribution anchored by caryophyllene, myrcene, and limonene. This distribution is consistent with the perceived pepper, earth, and citrus components.
Flavor and Palate
On inhale, Auto White Prussian typically presents a clean citrus flicker that quickly merges into pine and light wood. The smoke or vapor is often notably smooth when properly cured, with sweetness trailing on the exhale. Peppery tingles on the tongue and palate are common, aligning with beta-caryophyllene dominance. A faint herbal bitterness—similar to green tea—may close the finish.
Through water filtration or vaporization at 350–390°F (177–199°C), the lemon-pine top note becomes more distinct. Vapor users frequently describe eucalyptus-like brightness at lower temps, which fades into a broader woody-spice canvas above 400°F (204°C). Flavors tend to stay relatively stable across a session, with only mild “hashy” deepening toward the end. Resin-heavy phenotypes produce a pleasantly persistent aftertaste.
Joint or dry-herb vape tasters often pick up a sweet herbal candy character after a few pulls. That sweetness is subtle and can be muted by an overly rapid dry or under-cured material. Given proper curing, the palate shows good balance without one note overwhelming the others. The result is a familiar, European-style flavor profile that appeals to classic hybrid fans.
When paired with beverages, citrus-forward sparkling water or lightly sweetened iced tea complements the lemon-wood dynamics. Dark, heavily roasted coffees can overwhelm the nuance; medium-roast or citrusy pour-overs pair better. Savory snacks with rosemary, black pepper, and sea salt resonate nicely with the herb-spice matrix. Connoisseurs often recommend glassware over silicone to keep flavors clean.
Combustion harshness is usually low if moisture content is stabilized around 10–12% before first light. At this moisture level, burn rate is steady and white ash is more attainable, though ash color is an imperfect proxy for quality. Over-dry buds (<9% moisture) will taste sharper and lose citrus lift more quickly. Proper humidity control preserves the full flavor arc for weeks.
Cannabinoid Profile and Potency
As a ruderalis/indica/sativa hybrid, Auto White Prussian is generally positioned for mid-to-high THC potential rather than CBD richness. Across modern autos with similar heritage, growers commonly see THC results in the mid-teens to low-20s percent range when cultivation is optimized. That places average potency around 15–22% THC, with outliers possible in either direction. CBD typically registers low, often below 1%, with occasional phenotypes landing in the 0.2–0.6% band.
Minor cannabinoids can contribute measurable effects despite their lower concentrations. CBG frequently appears in the 0.1–0.5% range in comparable autos, supporting a subtle steadying effect. Trace CBC and THCV may be present in hundredths to tenths of a percent, depending on phenotype and environmental stressors. These compounds interact with terpenes to influence onset, mood tone, and duration.
Harvest timing significantly affects perceived potency and effect balance. When trichomes are mostly cloudy with 5–10% amber, the headspace leans toward clarity and uplift, which many associate with peak THC-to-degradation-product ratio. At 15–30% amber, the experience typically deepens into heavier body relaxation due to increased oxidized cannabinoids and sedative terpenoid shifts. Monitoring trichomes under 60–100x magnification provides actionable data for dialing preference.
Delivery method changes intensity and duration. Inhalation reaches peak plasma THC within minutes, with subjective effects often lasting 2–3 hours before tapering. Oral routes show delayed onset (30–120 minutes) with a longer plateau of 4–8 hours, creating a different potency perception. The same batch can feel “stronger” edible than smoked due to 11-hydroxy-THC formation in the liver.
Tolerance, set and setting, and nutritional status modulate potency experience. Users who abstain for 48–72 hours can perceive a noticeable reset, reflected in lower effective doses. Hydration and caloric intake influence onset speed and nausea sensitivity for edible formats. These variables should be considered when interpreting potency across sessions.
Terpene Profile and Chemistry
Auto White Prussian’s sensory signature aligns with a terpene ensemble anchored by beta-caryophyllene, myrcene, limonene, and pinene. In comparable balanced autos, total terpene content of 1.2–2.2% by dry weight is common under good cultivation and careful post-harvest handling. Beta-caryophyllene often contributes 0.2–0.6% of dry weight in spicy phenotypes, while myrcene may fall around 0.3–0.8%. Limonene typically spans 0.1–0.4%, with alpha/beta-pinene adding 0.05–0.3% combined.
Beta-caryophyllene is unique because it directly engages CB2 receptors, which are associated with peripheral anti-inflammatory signaling. This interaction may explain why pepper-forward cultivars sometimes feel calming in the body without inducing sedation. Myrcene, depending on concentration and context, can enhance the perception of relaxation and modulate blood-brain barrier permeability in animal models. In human experience, myrcene-rich aromas often read as earthy-sweet with a softening effect.
Limonene contributes the citrus snap and is frequently associated with elevated mood and alertness. Its volatility means it is among the first terpenes to be lost when drying is too hot or airflow is too aggressive. Pinene is linked to perceived mental clarity and can lend the eucalyptus-pine nuance some phenotypes express. Maintaining lower drying temperatures helps preserve both limonene and pinene.
Humulene and ocimene may appear in trace-to-modest amounts, adding woody, herbal, and verdant floral threads. Linalool is usually minor in this cultivar type but can add a faint lavender sweetness in some expressions. These secondary terpenes shape the mid-palate and aftertaste and can subtly shift the relaxation-versus-alertness balance. Even small changes in their proportions are noticeable in the nose.
From a chemical handling perspective, terpene preservation benefits from gentle post-harvest practices. Targeting 60°F/60% RH and 10–14 days of slow drying minimizes monoterpene loss. Water activity around 0.55–0.65 during cure stabilizes aromatics and reduces microbial risk. Burping jars less frequently after the first week helps conserve volatiles while preventing anaerobic notes.
Experiential Effects and Use Cases
Many users describe Auto White Prussian as balanced and sequence-driven: a clear, motivating onset followed by a steady body ease. The sativa-leaning headspace can feel social and focused for the first 45–90 minutes with inhalation. As effects progress, indica influence builds a comfortable calm in the shoulders and torso without heavy couchlock for most. The result often works well for daytime or early evening when dosed conservatively.
Mood elevation is a consistent theme, frequently paired with mild sensory brightening and a noticeable reduction in mental chatter. Tasks that benefit from light focus—tidying, cooking, or creative brainstorming—can feel more engaging during the peak. Some users report improved patience and reduced irritability, consistent with limonene and pinene’s brightening roles. Overconsumption, however, may tip the experience toward racy or foggy, depending on individual sensitivity.
Body effects trend toward muscle comfort and a softened pain perception, especially in the back and neck. This calm is present without the pronounced heaviness common to more sedative indica-dominant autos. In social settings, the cultivar’s friendly headspace can reduce awkwardness and promote conversation. For sensitive users, starting with smaller puffs or lower-potency preparations helps avoid overstimulation.
In larger doses or late-night sessions, the tail-end can shift to restful, making it acceptable as a wind-down option. The hybrid balance means it is not a dedicated sleep strain, but many find it compatible with relaxation rituals. Pairing with quiet music and low lighting complements the body ease and keeps the mind from re-accelerating. Hydration and a light snack can smooth the landing.
Duration for inhalation commonly spans 2–3 hours with a gentle taper, while edible formats extend longer with a delayed crest. Individuals with lower tolerance may prefer microdosing via a few short draws to retain the bright headspace without entering couchlock territory. As with any cannabis, set and setting shape outcome: calm environments and intentioned use enhance positive effects. Users susceptible to anxiety should keep doses modest and choose fragrant, well-cured buds that preserve uplifting terpenes.
Potential Medical Applications
Auto White Prussian’s ruderalis/indica/sativa balance positions it as a versatile option for several symptom domains reported anecdotally by patients. The caryophyllene-forward spice and potential CB2 engagement may support peripheral inflammation modulation. Many users report relief for mild-to-moderate musculoskeletal discomfort, especially tension-related neck and back tightness. The relatively clear headspace in lighter doses also makes daytime symptom management more feasible for some individuals.
For mood-related concerns, limonene and pinene are commonly associated with elevated affect and perceived cognitive brightness. Some patients describe reduced stress reactivity and improved task initiation in low-to-moderate doses. Those susceptible to cannabis-induced anxiety should start low and remain in environments that feel safe and predictable. Slow titration helps identify a personal therapeutic window.
In appetite and gastrointestinal comfort, THC’s orexigenic properties can encourage eating for individuals experiencing reduced hunger. The cultivar’s balanced profile means appetite stimulation may arrive without overpowering sedation. Nausea relief is frequently reported with inhaled cannabis due to rapid onset, which can be beneficial during acute episodes. Vaporization is often preferred to avoid smoke, especially for sensitive lungs.
Sleep support is possible as effects taper, though this is not a strictly sedative cultivar. Many find it useful for pre-sleep relaxation routines when dosed 1–2 hours before bedtime. If insomnia is the primary concern, phenotypes with slightly higher myrcene and harvests with more amber trichomes may be more helpful. Always monitor next-day grogginess and adjust timing.
Dosing considerations are crucial. Beginners might start around 1–2 mg THC-equivalent via vapor or tincture, waiting 15–30 minutes to assess before redosing. For edibles, 1–2.5 mg THC is a conservative entry point, with increases of 1–2 mg on subsequent sessions as needed. Individuals with cardiovascular, psychiatric, or complex medical histories should consult a clinician before use, especially when combining with other medications.
Comprehensive Cultivation Guide
Lifecycle and Scheduling
Auto White Prussian is designed to finish quickly, commonly in 9–11 weeks from sprout under optimal indoor conditions. Preflower typically appears around day 21–28, at which point vertical growth accelerates for 10–14 days. Because autoflowers are age-triggered rather than photoperiod-dependent, you cannot extend veg by changing light cycles. Plan your root zone, training, and feeding strategy early to make the most of the short runway.
Indoors, many growers run 18/6 or 20/4 light schedules from seed to harvest to maximize photosynthesis while allowing nightly respiration. PPFD targets of 350–500 µmol·m⁻²·s⁻¹ in early growth, 600–800 in mid-flower, and up to 850–900 late flower are typical for quality results. This equates to a daily light integral (DLI) around 30–45 mol·m⁻²·day⁻¹ in peak bloom. Avoid sustained PPFD >1,000 for autos unless CO₂ is supplemented and irrigation is dialed.
Medium, Containers, and Root Zone
Autos prefer to start in their final container to avoid transplant shock. For Auto White Prussian, 11–18 L (3–5 gal) fabric pots balance size and speed for indoor tents. In coco or soilless mixes, aim for a pH of 5.8–6.2; in soil, maintain 6.2–6.8. Keep root zone temperatures between 68–72°F (20–22°C) for optimal enzyme activity and nutrient uptake.
A light, aerated substrate is ideal. Mixes of 60–70% high-quality peat or coco with 20–30% perlite and 10% compost or worm castings provide structure and microbial life. In coco, consistent fertigation with 10–20% runoff helps prevent salt accumulation. Fabric pots improve oxygenation and reduce overwatering risks, which is critical in autos’ fast timelines.
Nutrition and EC Management
Feed lightly in early growth, as autos can be sensitive to excess nitrogen before preflower. Typical EC targets for coco/soilless are 0.8–1.2 mS·cm⁻¹ in weeks 1–3, 1.2–1.6 in weeks 4–6, and 1.6–1.8 in weeks 7–9, tapering near harvest. Maintain adequate calcium and magnesium (100–150 ppm Ca and 50–75 ppm Mg) to prevent deficiency under LED lighting. In soil, use amended media and supplement with low-dose liquid feeds only as needed.
As flowering sets in, gradually shift toward phosphorus and potassium support while trimming excessive nitrogen to avoid leafy buds. A bloom ratio in the vicinity of N-P-K 1-2-2 or 1-3-2 (by relative proportion, not absolute ppm) is common from mid-flower onward. Monitor leaf tips and margins for burn as an early sign to reduce feed strength. Consistency is more important than maximal feeding with autos.
Environment, VPD, and Airflow
Target 75–79°F (24–26°C) day and 68–72°F (20–22°C) night for most of the cycle. Maintain relative humidity around 60–65% in early growth, 50–55% in early flower, and 40–50% in late flower. This corresponds to VPD ~0.8–1.0 kPa early, rising to 1.0–1.2 kPa mid-to-late bloom. Strong but gentle airflow reduces microclimates and lowers powdery mildew risk.
Autos like steady conditions; large temperature or humidity swings can reduce growth efficiency. Use oscillating fans to move air through and around the canopy without causing windburn. If smells intensify, deploy a properly sized carbon filter and maintain slight negative pressure. Replace carbon periodically; spent filters are a common cause of late-cycle odor leaks.
Training and Canopy Management
Because of the short veg window, prioritize low-stress training (LST) and strategic tie-downs over heavy topping. If topping, do so only once and very early (day 15–20) to avoid stunting; many growers skip topping on autos entirely. LST can open the canopy, promote even light distribution, and stack secondary colas. Remove only the most shaded lower growth that is unlikely to mature; avoid aggressive defoliation.
Spacing plants 30–45 cm (12–18 inches) apart improves airflow and reduces disease pressure. Canopy uniformity helps keep all tops within the ideal PPFD band. Consider a gentle SCROG net as a guide for tie-downs rather than a rigid structure that complicates harvest. Keep the main cola at or just under the light’s sweet spot late bloom.
Watering Strategy
Autos prefer consistent moisture without saturation. In soilless systems, smaller, more frequent irrigations are superior to occasional drenching; aim for 10–20% runoff to manage EC. In soil, water thoroughly but infrequently, then allow the top 2–3 cm to dry before the next irrigation. Use pot weight and finger checks; automated schedules are helpful but should be verified.
Avoid cold water that can shock roots; aim for 65–72°F (18–22°C) irrigation temperature. If your tap water is soft (<100 ppm), consider adding a cal-mag supplement to avoid deficiencies. Conversely, if starting EC is high (>0.4 mS·cm⁻¹), reconcile your nutrient plan to keep total EC within targets. A simple handheld EC and pH meter can prevent many issues.
Pests, Pathogens, and IPM
Preventative integrated pest management (IPM) is more efficient than rescue treatments in a short auto cycle. Sticky cards, weekly leaf inspections, and cleanliness form the backbone of early detection. Beneficials such as Neoseiulus californicus and Amblyseius swirskii can be introduced prophylactically against mites and thrips. Avoid oil-based sprays late in flower to prevent residue on buds.
Powdery mildew and botrytis are the primary disease risks in dense, resinous flowers. Keep RH within targets, maintain airflow, and defoliate lightly for penetration if needed. UV-C and advanced sterilization tools exist but should be used cautiously to protect plant tissue and human eyes/skin. For late-stage humidity spikes, a dehumidifier tied to a humidity controller is invaluable.
Outdoors and Greenhouses
Auto White Prussian performs well outdoors in temperate climates due to its speed and ruderalis resilience. Height often stays in the 60–100 cm range, making it discreet for balconies and patios. Plant after the last frost when night temperatures are reliably above 50°F (10°C) to prevent early stress. A full-sun site (6–8+ hours) boosts terpene and cannabinoid development.
In the ground or large fabric pots (25–40 L) with living soil, autos can show surprising vigor. Consider light teas or top-dressing rather than strong bottled feeds to avoid overshooting nutrition. Drip irrigation stabilizes moisture during heat waves and reduces disease from splash. Use physical barriers or cages to protect against pests and wind.
Expected Yields and Performance Metrics
Yield depends on light, environment, and grower experience. Indoors under efficient LEDs and good dial-in, many growers report 350–500 g·m⁻² with this type of compact auto, with skilled runs surpassing that under optimized canopies. Outdoor single-plant yields vary widely, commonly 40–120 g per plant in modest pots and substantially more in larger organic beds. Denser bud formation and higher calyx-to-leaf ratios typically improve post-trim weights.
Quality metrics matter alongside raw yield. Target 10–12% final moisture content and water activity between 0.55–0.65 to preserve terpenes and avoid mold. Aim for trichomes mostly cloudy with 5–20% amber for balanced effects, based on personal preference. Keep a simple grow log noting EC, pH, temp/RH, and observations to correlate decisions with outcomes.
Harvest, Drying, and Curing
Harvest windows commonly land between days 63–77 from sprout, though some phenotypes may run a week longer. Use trichome color, not just breeder timelines, to decide when to chop. Flush or taper feed during the final 7–10 days if you are using salt-based nutrients, watching for natural fade. Harvest at the start of the light period to minimize volatile losses.
Dry in the dark at ~60°F (15.5°C) and 55–60% RH for 10–14 days with gentle air exchange. Whole-plant or large-branch hangs slow the process for better terpene retention. After stems snap rather than bend, jar the buds and cure at 58–62% RH, burping daily for the first week, then less often. A 4–8 week cure smooths the smoke and layers the citrus-pine-herbal profile.
Safety and Compliance
Always comply with local cultivation laws regarding plant counts, visibility, and security. Use GFCI outlets, proper cable management, and fire-safe equipment in indoor setups. Wear gloves and eye protection when mixing nutrients or handling sulfur, hydrogen peroxide, or alcohol. Maintain a clean, organized grow area to prevent accidents and cross-contamination.
Strain-Specific Tips and Summary
Given the cultivar’s resin-forward nature, keep late-flower RH closer to 45–50% to reduce botrytis risk in dense colas. Prioritize LST over topping to maintain momentum in the short veg window. Keep nitrogen modest once pistils proliferate to avoid leafy flowers and muted terpenes. With stable conditions and attentive inputs, Auto White Prussian rewards with frosty, citrus-pine-spice buds that punch above their size and speed.
