Mint Jelly Auto (Cannabis Strain) — Strainpedia
Mint Jelly Auto is a modern Indica-Dominant Autoflower cultivar developed by Humboldt Seed Company (HSC), widely recognized as one of the most important breakthroughs in the 2026 autoflower market. Engineered through extensive multi-generational stabilization (Bx4), this cultivar was specifically designed to deliver photoperiod-level terpene complexity and extraction-grade resin density within a rapid autoflower lifecycle. Known for its “After Eight mint dipped in jelly” aroma profile, Mint Jelly Auto has become a flagship cultivar for 2026 extraction artists, prized for its greasy trichomes, high wash efficiency, and extreme potency for an auto (often cited in the 25%–30% THC range). The information below is intended strictly for scientific and botanical reference.

|---|---|
| Variety | Indica-Dominant Autoflower (approx. 60% Indica / 40% Sativa) |
| Lifecycle | 70–80 days (seed to harvest) |
| Yield Potential | 350–500 g/m² indoors; 85–220 g/plant outdoors |
| Plant Height | 80–120 cm (Stout, vigorous autoflower structure) |

Scientific & Botanical Overview
Mint Jelly Auto represents a major leap forward in autoflowering cannabis breeding. Plants typically develop a stout, vigorous structure with dense branching and thick stems that support heavy flower development without extensive trellising. Colas often form as compact, rock-hard clusters that stack efficiently, making the cultivar highly productive for both small-scale home growers and commercial auto runs.
Bud coloration is often green with purple expression, accompanied by vibrant orange pistils and a thick trichome layer that creates a distinct “wet” appearance under light. This cultivar is widely referenced as a prime example of modern autoflower resin advancement, with a greasy trichome texture specifically selected to improve solventless extraction performance.
Effects & Use-Cases (Reported)
- Commonly reported effects: rapid euphoria, cerebral uplift, creative stimulation, followed by heavy physical sedation and couch-lock potential.
- Use-case context: late afternoon and evening sessions; relaxation-focused use with strong body decompression.
- Progression: uplifting onset followed by a mind-numbing Indica fade that becomes increasingly narcotic over time.
- Potency note: frequently described as unusually strong for an autoflower cultivar.
- Note: These are observational reports, not medical claims; outcomes are not guaranteed.
Aroma & Flavors
- Aroma: sweet peppermint glaze and mint candy layered with vanilla cake batter, supported by a subtle gassy undertone.
- Flavor: minty pastry sweetness on the inhale followed by a rich “jelly-filled” sugary finish. The exhale is creamy, smooth, and expands noticeably in the lungs.
- Terpene associations: limonene, caryophyllene, myrcene, linalool (implied mint-dessert-gas complexity).
Tested Cannabinoid & Terpene Ranges
| Compound | Typical Range* | Notes |
|---|---|---|
| Δ⁹-THC | ~25–30% | Extreme outlier potency range for autoflower genetics; considered elite-grade strength. |
| CBD | ~0–1% | Generally present only in trace levels. |
| Limonene | Moderate–High | May contribute citrus brightness and uplifting onset euphoria. |
| Caryophyllene | Moderate | Adds gassy spice depth and supports body calming effects. |
| Myrcene | Moderate–High | Likely supports the narcotic Indica fade and couch-lock potential. |
| Linalool | Low–Moderate | May contribute vanilla sweetness and smooth calming balance. |
| Terpene Profile | Mint Pastry / Jelly Sweetness / Gas Undertone | Designed as a top-shelf dessert terpene profile for flower and extraction. |
*Ranges are literature- and lab-report-informed references and can differ with phenotype, cultivation conditions, harvest timing, curing practices, and analytical methods.
Cultivation Notes
- Light Cycle: Autoflower standard 18/6, 20/4, or 24/0 (depending on grow strategy)
- Humidity Targets: 45–55% early flower; 40–50% late flower due to dense colas.
- Nutrition: moderate feeder; thrives on stable feeding and consistent root-zone health.
- Training: responds well to LST and SOG setups; avoid aggressive topping unless highly experienced with autos.
- Resilience: known for strong resistance to common stressors, making it suitable for beginner and closet growers.
- Harvest Window: typically 70–80 days from germination, depending on environment and phenotype.
Grower Notes (Lifecycle Snapshot)
- Days 1–14 (Seedling/Early Veg): establish strong root zone; avoid overwatering; begin gentle LST only if desired.
- Days 15–28 (Rapid Veg/Pre-Flower): explosive growth; structure becomes stout and branch-heavy; ideal time for canopy shaping.
- Days 29–45 (Flower Set): dense bud stacking begins; aroma becomes sweet-minty; maintain airflow and stable feeding.
- Days 46–60 (Bulk & Resin Surge): peak trichome development; buds become rock-hard and heavily frosted.
- Days 61–80 (Ripening): terpene maturity; mint and jelly sweetness intensifies; harvest based on trichome maturity.
- Post-Harvest: Dry 18–20 °C, 55–60% RH to preserve delicate mint-dessert terpenes and maintain resin quality.
Autoflower timelines shift with light intensity, pot size, and environment; prioritize trichome maturity over strict calendar counts.
Genetic Lineage
Mint Jelly Auto is bred from Sour Apple Auto and Hella Jelly, combining autoflower stability with elite photoperiod-grade resin and terpene depth. Sour Apple Auto provides the vigorous autoflower backbone, rapid lifecycle consistency, and sharp gassy citrus foundation. Hella Jelly (Notorious THC x Very Cherry) contributes the signature “jelly sweetness,” high THC potential, and extreme resin production. Through multi-generational backcross stabilization, Humboldt Seed Company engineered Mint Jelly Auto to perform like a boutique photoperiod cultivar while retaining the speed and simplicity of autoflower cultivation.
Research Insights
Mint Jelly Auto is frequently cited as a defining cultivar of the 2026 “Autoflower Revolution,” demonstrating that modern autos no longer require sacrifices in potency or terpene expression. Its reported 25%–30% THC range is considered a biological outlier in autoflower genetics, and its greasy trichome texture suggests deliberate resin gland selection for ice-water hash and rosin performance. The strain’s reputation as an extraction masterpiece likely reflects its combination of gland head density, terpene persistence, and high resin-to-flower ratio—traits historically reserved for elite photoperiod cultivars.
