Overview And Naming

Missile 33 is a so-called SuperAuto cannabis variety bred by Flash Seeds, a breeder known for pioneering oversized autoflowering lines. The strain’s name hints at speed and power, with 33 often interpreted by growers as a nod to rapid finish windows or a particular phenotype index within a breeding program. While public, lab-verified data is limited, the strain appears in third-party strain indexes, including the CannaConnection sitemap, under the listing Missile 33 SuperAuto.

As a ruderalis, indica, and sativa hybrid, Missile 33 is designed to flower based on age rather than day length. This makes it accessible to cultivators who prefer a straightforward 18–20 hour light cycle from seed to harvest. The SuperAuto designation typically means larger stature, more robust branching, and a life cycle longer than standard autos but still shorter and simpler than photoperiods.

Flash Seeds’ catalog has long emphasized big yields and vigorous growth in autoflower format. Missile 33 follows that ethos by blending hybrid vigor with day-neutral genetics. The end result aims for a balance of resin production, harvest speed, and outdoor resilience that suits both new and experienced growers.

History And Breeding Background

Flash Seeds, active through the 2010s, helped define the SuperAuto category by crossing vigorous photoperiod genetics with carefully selected ruderalis donors. The goal was to produce plants that keep the manageable light schedule of autos while reclaiming the size and intensity of photoperiod hybrids. Missile 33 fits into this movement as one of the SuperAuto entries attributed to Flash Seeds.

Evidence of Missile 33’s recognition in the wider cannabis community appears in index pages like the CannaConnection sitemap, which lists Missile 33 SuperAuto among known cultivars. Such listings signal that the variety circulated enough to be cataloged by third-party strain databases. This is notable for an autoflower, as SuperAutos often occupy a niche between micro autos and full photoperiods.

Although breeder notes specific to Missile 33 are scarce in public archives, the Flash Seeds pedigree implies a development arc similar to other SuperAutos: multiple filial generations to stabilize the day-neutral trait and select for increased biomass. In practice, this often yields plants that take 80–100 days from seed indoors, depending on phenotype. The trade-off is more time than micro autos, but with a commensurate jump in structure and yield potential.

Genetic Lineage And Inheritance

Missile 33’s stated heritage is ruderalis, indica, and sativa, indicating a true hybrid with day-neutral flowering. Ruderalis contributions are typically responsible for the autoflowering trait, faster maturation, and cold tolerance. Indica and sativa inputs tune the chemotype, morphology, and psychoactive profile.

In hybrid theory, ruderalis segments often occupy 20–35% of the genome in robust autos that still carry substantial resin output. Indica and sativa parentage can be split in various ratios to steer plant structure and effect. SuperAutos commonly lean 60–80% photoperiod ancestry to reclaim density, branching strength, and terpene intensity.

From an agronomic standpoint, Missile 33 likely expresses heterosis, or hybrid vigor, especially in early growth. This can manifest as thicker petioles, rapid node stacking, and well-fueled lateral growth. Such vigor is advantageous when working under long photoperiods, as autos cannot be forced to veg longer; they must establish mass quickly.

Appearance And Plant Morphology

Growers should expect Missile 33 to present as a midsized to large autoflower with a strong central cola and pronounced radial branches. Typical SuperAuto heights fall between 80 and 140 cm indoors, with outdoor plants sometimes pushing beyond 150 cm in favorable climates. Internode spacing tends to be moderate, with good calyx development balancing leaf mass.

Buds often mature into conical or spear-shaped colas, with secondary tops forming along upper and mid branches. A calyx-to-leaf ratio around 2:1 to 3:1 is common for resinous SuperAutos, easing trimming without sacrificing mass. Mature flowers exhibit a dense trichome coat, appearing frosty under neutral light and sticky to the touch.

Coloration ranges from lime to medium green, occasionally displaying lavender tints at lower night temperatures. Pistils typically begin cream to orange and shift to deeper amber near harvest. The plant’s skeletal structure supports a screen-of-green approach or gentle low-stress training to flatten the canopy and even light distribution.

Aroma Profile

While lab-verified terpene reports for Missile 33 are limited publicly, analogous hybrid autos from Flash Seeds commonly exhibit layered aromas. Expect a baseline of sweet earth and herbal notes, often associated with myrcene-forward profiles. Citrus or orange-zest top notes frequently emerge from limonene or terpinolene contributions.

A peppery, woody undertone is likely due to beta-caryophyllene and humulene. These compounds can add a savory edge that anchors the sweeter facets. Some phenotypes may show a faint fuel or solvent twang, a marker often tied to complex monoterpene interactions and minor sulfurous volatiles.

In cured flower, the bouquet typically intensifies during weeks two to four of cure. Jar-opening releases a burst of mixed sweet-spice, sometimes hinting at dried mango, cracked black pepper, and pine. Properly dried buds with 10–12% moisture content tend to preserve the higher volatiles and reduce grassy chlorophyll notes.

Flavor And Consumption Experience

On the palate, Missile 33 is likely to track its aroma with sweet herbal entry, citrus accents, and a peppered finish. Initial inhales may present as smooth if cured slowly at 58–62% relative humidity. Combustion can pull out toasted spice and mild pine resin notes, while vaporization often exposes more fruit and floral lilt.

Common vaporizer temperatures of 175–190 C emphasize limonene and myrcene sweetness. Raising to 195–205 C unlocks deeper caryophyllene spice and a more sedative edge. Many users report that flavor persistence, or finish, is most noticeable on exhale where the pepper-citrus interplay lingers.

For concentrates pressed from SuperAuto flowers, expect a terpene-forward rosin with an amber-gold hue if pressed at 90–100 C for 60–120 seconds. Flavor density correlates with flower terpene content and cure quality. Lower press temps usually retain brighter citrus top notes and reduce bitterness.

Cannabinoid Profile And Potency

Publicly accessible, lab-certified cannabinoid data for Missile 33 are scarce, so reasonable ranges are based on similar Flash Seeds SuperAuto hybrids. Many SuperAutos from established breeders test between 14% and 22% THC when grown competently, with outliers reaching the mid-20s. CBD content is usually low, commonly under 1%, unless a CBD-rich phenotype was intentionally included.

In retail markets, average THC for autoflower hybrids often centers around 18–20% with total cannabinoids around 20–24%. Total cannabinoids include THC, THCa, minor THCV, CBG, and trace CBC or CBN depending on maturity and storage. A small fraction of samples can show CBG near 0.5–1.0% if harvest timing leans slightly early.

Practical potency is a function of both chemistry and delivery. A joint of 0.5 g at 18% THC contains roughly 90 mg THC total, with inhalation bioavailability estimated at 10–35% depending on technique and device, which translates to around 9–32 mg absorbed. Users calibrating dose should start low, especially when unfamiliar with an autoflower hybrid’s onset profile.

Terpene Profile And Minor Volatiles

Based on typical hybrid autos and anecdotal reports, total terpene content for plants like Missile 33 often falls between 1.5% and 2.5% by dry weight when well grown. Some craft-grown samples can exceed 3.0% under optimized conditions. Common primary terpenes include myrcene, limonene, and beta-caryophyllene, which together can represent 40–70% of the total terpene fraction.

Likely secondary terpenes include humulene, linalool, and ocimene, with trace amounts of pinene and terpinolene. Myrcene often drives the herbal-sweet earth core, limonene contributes citrus brightness, and caryophyllene adds peppered spice while interacting with CB2 receptors. Humulene complements caryophyllene with woody dryness, and linalool introduces a soft floral lift.

Minor volatiles such as esters and ketones can shape perceived fruit notes, especially during the first 6–8 weeks of cure. Sulfur-containing molecules, even at parts-per-billion levels, may add faint fuel nuances in certain phenotypes. Proper dry and cure protocols are crucial to preserve these sensitive compounds and prevent terpene oxidation.

Experiential Effects And Onset

Missile 33’s hybrid nature often produces a balanced mental and physical effect profile. Expect an initial lift within 2–5 minutes of inhalation, characterized by mood elevation and light sensory clarity. As the session continues, a warm body presence tends to build, easing tension without immediate couchlock in moderate doses.

The limonene and myrcene interplay commonly yields a happy calm effect that can suit late afternoon or early evening use. Caryophyllene’s presence may temper edginess for some users, offering a grounded finish. At higher doses, the experience often deepens into heavier relaxation and introspection.

Average duration of psychoactivity for smoked or vaped flower ranges from 2 to 3 hours, with a taper rather than a hard drop-off. Novice users may find 1–2 inhalations sufficient, while experienced consumers may prefer 2–5 inhalations to reach a functional plateau. As always, setting, hydration, and tolerance strongly modulate the subjective experience.

Tolerance, Side Effects, And Functional Context

Like many mid-to-strong hybrids, repeated daily use can build tolerance in 3–7 days, reducing intensity. Cycling days off or alternating with lower-THC chemovars can help restore sensitivity. Common side effects include dry mouth and dry eyes, reported by over 30–50% of users in surveys across hybrid categories.

Anxiety or racy feelings are possible in sensitive individuals, especially if the phenotype leans more sativa in effect. Starting with small doses and focusing on calm settings reduces this risk. Snack cravings and transient short-term memory lapses are also commonly reported in the 20–40% range for comparable hybrids.

Functionally, Missile 33 can slot into creative, social, or unwind scenarios at different doses. Low doses may pair with light tasks, music, or walks. Higher doses skew toward movies, gaming, or end-of-day decompression.

Potential Medical Uses

Potential therapeutic applications are inferred from the likely chemotype and terpenes rather than clinical trials on Missile 33 specifically. THC-dominant hybrids with caryophyllene often see anecdotal use for stress reduction and mood support. Limonene has been associated with perceived uplift and a brighter affect in user reports.

Myrcene and linalool, where present, may contribute to body relaxation and sleep-quality support, especially in the latter part of the effect window. Users managing mild to moderate pain sometimes report relief when caryophyllene and humulene are present due to their anti-inflammatory potential in preclinical literature. Nausea control is a common reason THC-dominant flower is selected, with rapid onset providing timely benefit for some.

Medical outcomes are individualized and depend on dose, tolerance, and coexisting conditions. Start low and titrate slowly, particularly for anxiety-prone individuals. This content is informational only and not medical advice; patients should consult a qualified clinician.

Cultivation Guide Overview

Missile 33, as a SuperAuto, rewards growers who balance vigor with gentle handling. Autos start flowering by age, so the first 3–4 weeks are critical for root establishment and canopy setup. Avoid severe pruning or transplant shock during this window to preserve final yield.

Indoors, expect 80–100 days from seed to harvest for most phenotypes under an 18–20 hour photoperiod. Outdoors, the total cycle can extend to 90–120 days depending on latitude and temperature. Target medium to large containers to allow ample root mass and stable moisture profiles.

Given typical SuperAuto genetics, indoor yields of 450–600 g per square meter are achievable with dialed-in environments and high-efficiency LEDs. Outdoors, 80–200 g per plant is a realistic range, with well-grown giants exceeding 250 g in long, warm seasons. Environmental controls, careful nutrition, and low-stress training are the core levers for success.

Germination And Seedling Management

Germinate seeds using a clean, oxygenated approach such as a pre-soaked plug, rapid rooter, or paper towel at 22–25 C and 90–100% RH. Most viable seeds pop within 24–72 hours. Plant into the final container early to avoid transplant shock that can stall autos.

In the first 10–14 days, provide gentle light at 200–300 PPFD with 18–20 hours per day. Maintain VPD around 0.8–1.0 kPa, which corresponds roughly to 24–26 C and 60–70% RH. Keep media evenly moist but not saturated to promote lateral root expansion.

Early feeding should be light, aiming for EC 0.6–0.9 in hydro or inert substrates, and 100–200 ppm N in soil blends. Calibrate pH to 5.8–6.2 for hydro and 6.2–6.8 for soil. Introduce beneficial microbes or mycorrhizae at transplant to support nutrient uptake and stress resilience.

Vegetative Growth For SuperAutos

From days 10–28, increase light intensity to 300–450 PPFD while maintaining 18–20 hours of light. Temperatures of 24–28 C by day and 20–22 C by night support rapid metabolism. Hold RH around 55–65% to balance transpiration and pathogen suppression.

Raise feed strength to EC 1.0–1.4 in hydro and provide a balanced nutrient profile in soil or coco. Nitrogen should be adequate but not excessive, with Ca and Mg supplementation as needed for LED setups. Ensure consistent irrigation with 10–20% runoff in coco/hydro to prevent salt buildup.

Monitor for preflowers that may appear by days 18–25. Once pistils emerge, the plant is already committing to bloom; avoid heavy defoliation or topping at this stage. Gentle low-stress training remains the preferred method to expand canopy width without stunting.

Training, Pruning, And Canopy Management

Autos like Missile 33 respond best to low-stress training beginning around nodes 4–6, when stems are still pliable. Bend and tie the main stem to promote multiple tops and even light distribution. A single topping can be attempted early, but many growers skip it to avoid growth stalls.

Selective leaf tucking improves airflow and exposes bud sites without removing too many solar panels. If defoliating, remove only 10–20% of large fan leaves at a time and allow several days of recovery. Screens can be used passively to guide branches but avoid aggressive weaving that damages tissue.

Maintain 15–25 cm between canopy and light in late bloom for high-efficiency LEDs, adjusting to PPFD 600–900 depending on cultivar response. Target Daily Light Integral of 35–45 mol m−2 d−1 in flower. Watch for light stress markers like tacoing or bleaching and adjust accordingly.

Nutrition And Irrigation Strategy

In early bloom, increase EC to 1.4–1.8, with phosphorus and potassium rising as nitrogen gradually tapers. Mid to late bloom may run best at EC 1.8–2.1 in coco or hydro, while rich living soils may require only water and light teas. Calibrate pH daily and monitor runoff EC to track salt accumulation.

Autos benefit from steady, moderate nutrition rather than feast and famine cycles. Maintain substrate moisture in the 35–55% range by volume for coco and 25–45% for soil to keep roots oxygenated. In drip systems, small, frequent pulses can stabilize EC and root-zone temperature.

Supplement with silica during vegetative growth to fortify cell walls and support heavy colas. Magnesium demand can spike under strong LEDs; 25–50 ppm Mg additions often prevent interveinal chlorosis. Consider finishing with a 7–10 day low-EC phase to improve burn quality and reduce harshness.

Environmental Controls: Light, Temperature, RH, And VPD

Keep lights at 18–20 hours daily throughout the cycle to maximize autoflower metabolism. In vegetative-leaning weeks, 300–450 PPFD supports sturdy growth; in bloom, 600–900 PPFD is typical for efficient LEDs. Ensure uniform distribution with 0.8–1.0 uniformity across the canopy.

Ideal day temperatures are 24–28 C, with nights 4–6 C cooler to enhance color and terpene retention without slowing metabolism. Maintain RH at 55–65% in veg and 45–55% in bloom to reduce botrytis risk. Corresponding VPD targets are roughly 0.8–1.1 kPa in veg and 1.2–1.5 kPa in flower.

Increase air exchanges to 30–60 per hour in small tents using oscillating fans and filtered intakes. CO2 enrichment to 900–1200 ppm can raise photosynthetic rates under high PPFD, though benefits are modest in autos compared to photoperiods. Always balance CO2 with temperature, light intensity, and adequate nutrition.

Mediums, Containers, And Root Health

Missile 33 performs well in light, airy substrates that encourage rapid root expansion. Coco coir with 20–30% perlite offers excellent oxygenation for autos. High-quality soil blends with added aeration, such as 15–25% perlite or pumice, are also effective.

Container size influences final plant mass in autos, where root volume and vegetative time are limited. Use 11–19 L containers for large SuperAutos, or 7–11 L for more compact setups. Fabric pots or air-pruning containers help prevent circling roots and promote dense root mats.

Keep root-zone temperatures between 20–23 C and avoid prolonged saturation. Enzymes or microbial inoculants can help prevent root rot and improve nutrient cycling. If transplanting is necessary, do it once and early, moving from a small starter to the final pot before day 10–12.

Integrated Pest And Pathogen Management

Preventive IPM is essential for dense SuperAutos. Start with clean genetics and quarantine new plants. Use sticky cards to monitor flying pests like fungus gnats and thrips.

Beneficials such as Hypoaspis miles for gnats and Amblyseius cucumeris for thrips can be introduced proactively. Foliar sprays with oils or soaps should be used carefully and avoided on forming buds. Maintain canopy airflow of 0.5–1.5 m s−1 to deter powdery mildew and botrytis.

Sanitation practices, including wiping surfaces and sterilizing tools, reduce pathogen load. Keep leaf surfaces dry during lights-off to prevent microclimate spikes. Remove plant debris promptly and avoid overwatering, which can swing RH and invite molds.

Flowering, Ripening, And Harvest Timing

Preflowers often appear by days 18–25, with pistil clusters building through days 35–50. Bulk accumulation accelerates around days 50–70, when calyces swell and trichome production peaks. Late stages see pistils darken and retract as bracts stack.

Use a 60–100x loupe to track trichome development. Many growers harvest when trichomes are around 5–10% clear, 70–85% cloudy, and 10–20% amber for a balanced effect. Harvest earlier for a brighter, racier profile or later for heavier body presence.

Flush strategies vary by medium and philosophy. In inert media, many run low-EC inputs for 7–10 days to reduce residual salts. In living soil, aim for a consistent, biologically active finish with minimal disruption.

Drying, Curing, And Storage

Dry whole plants or large branches at 16–20 C and 55–60% RH for 7–14 days. Aim for a slow dry that preserves terpenes and avoids hay aromas. Gentle airflow and darkness prevent UV degradation and terpene loss.

Once branches snap rather than bend, trim and jar at 58–62% RH using clean glass jars. Burp jars daily for the first week, then taper to every few days as moisture equalizes. A 4–8 week cure often enhances flavor complexity and smoothness.

Store finished flower in airtight containers in a cool, dark place. Avoid frequent temperature swings and excessive oxygen exposure. Properly cured flower can retain quality for several months, with terpene decline slowing under stable conditions.

Yield Expectations And Performance Metrics

Indoors under efficient LEDs, realistic yields range from 450 to 600 g per square meter with trained canopies. Exceptional runs with CO2 and high PPFD can approach or exceed 650 g per square meter in dialed rooms. Per-plant indoor yields in 11–19 L containers often land between 60 and 150 g depending on phenotype and training.

Outdoors, single plants commonly produce 80–200 g, with favorable climates and long seasons pushing 250 g or more. Grams-per-watt metrics vary from 0.7 to 1.4 g W−1 in optimized environments. Water consumption for mature plants typically averages 1–2 L per day indoors and 2–4 L per day outdoors, modulated by pot size and VPD.

Bud density and resin output are strongly tied to light intensity and canopy management. Keep average canopy PPFD above 600 in flower for best results. Track metrics like runoff EC, leaf temperature differential, and brix to steer incremental improvements.

Common Pitfalls And Troubleshooting

Overhandling autos is a frequent cause of reduced yields. Avoid multiple transplants, heavy topping, or aggressive defoliation after preflowers appear. Any stall during the critical first 3–4 weeks lowers terminal biomass in autos.

Nutrient issues often present as magnesium deficiency under strong LED lighting, visible as interveinal chlorosis on mid to upper leaves. Address with Mg supplementation at 25–50 ppm and ensure pH is in range. Excess nitrogen late in bloom can produce leafy buds and harsh smoke.

Environmental swings drive most quality losses. High humidity over 60% in late flower raises botrytis risk, while hot canopies above 30 C may cause terpene volatilization and foxtailing. Keep conditions steady and prioritize airflow and dehumidification.

Outdoor Placement And Seasonality

Autos like Missile 33 allow flexible outdoor planting windows since they are day-neutral. In temperate zones, successive plantings every 3–4 weeks from late spring through midsummer can stagger harvests. Aim for average daily temperatures of 18–28 C for optimal growth.

Choose locations with 8+ hours of direct sun. Windbreaks protect tall SuperAutos from mechanical stress, and staking can support large colas. Mulch helps stabilize soil moisture and reduce root-zone heat.

Watch for early-season pests like aphids and caterpillars. Use physical barriers or biological controls before flowers set. Plan for late-season dehumidification or selective leaf removal if humidity surges during ripening.

Post-Processing And Extract Potential

Missile 33’s resin-rich phenotype can translate well to ice water hash and rosin techniques. Expect decent trichome retention in 90–120 micron ranges for full-melt attempts, depending on phenotype. Cleaner input and colder water improve separation and yield.

Mechanical separation yields of 3–5% of dried biomass are average for many hybrid autos under home conditions, with top phenotypes exceeding 5%. Pressing quality hash or dried flower at low temperatures preserves citrus and herbal top notes. Avoid over-pressing, which can co-extract waxes and reduce flavor clarity.

For ethanol or hydrocarbon extraction, monitor post-process purge carefully to protect delicate monoterpenes. Proper storage of extracts in cold, dark conditions slows terpene degradation. Label batches with date and conditions to track shelf life.

Sourcing And Authenticity

Missile 33 appears in third-party strain indexes, including the CannaConnection sitemap, under the title Missile 33 SuperAuto. This situates it within Flash Seeds’ SuperAuto family. When purchasing seeds, verify vendor reputation and lot freshness.

Look for breeder-sealed packs or resellers with strong guarantees. Poor storage can reduce germination rates, with viability dropping 10–20% annually if kept warm or exposed to moisture. Optimal storage is cool, dark, and dry, ideally below 10 C with desiccant.

Because SuperAutos can show some phenotypic variation, expect minor differences in height, finish time, and aroma among seeds. Selecting and documenting the best phenotypes over multiple runs will improve consistency. Keep notes on days to preflower, internode length, and resin density to guide future selections.

Responsible Use And Legal Considerations

Always follow local laws regarding cultivation, possession, and use of cannabis. Legal THC limits for cultivation can vary by jurisdiction and may include plant count, canopy size, or household caps. Compliance avoids fines, confiscation, and legal exposure.

When sampling new flower, start with small doses to gauge potency and effect. Wait at least 10–15 minutes between inhalations to understand onset progression. Never drive or operate dangerous equipment while impaired.

Store cannabis securely and out of reach of children and pets. Use child-resistant containers and clear labeling. Share responsibly and never sell without appropriate licensing where required.
