Spec sheet first — strain: hybrid, seed type: autoflower, THC: 29%, yield band: high, environment: indoor or outdoor.

Lineage: Mendo Breath × Headband × Trainwreck, all rooted in Mendocino Farms' Emerald Triangle outdoor program — and the combination shows. Guptilla Auto clocks in at 29% THC, which sits at the higher end of what most autoflowers actually test out at, not just claim. The 7–10 week flower window is tight for the output: 500g/m² is a realistic number here, not a marketing ceiling, provided plants get consistent light and aren't stressed early.

The citrus profile leans toward bright peel rather than juice — sharp on the inhale, cleaner on the way out. Effects run relaxed and heavy-lidded, which tracks with the Mendo Breath parentage. Moderate difficulty means you don't need a dialed-in grow room, but this one rewards growers who can manage feeding schedules without overcomplicating them. Best suited to intermediate growers who want genuine yield from an auto without babysitting a photoperiod run.

Genetics & Lineage

Guptilla Auto traces its genetics to Proprietary cross (Mendocino Farms). This hybrid-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Mendocino Farms, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 29%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Guptilla Auto delivers THC levels of 29%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing Guptilla Auto

Guptilla Auto is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 7-10 weeks with yields of 500g/m2. Plants typically reach 150-220cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Guptilla Auto features a citrus terpene profile that develops complexity throughout the flowering cycle. Bright lemon and orange zest punch through on the inhale, with a tangy, refreshing finish. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Guptilla Auto is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.
