Grapefruit Auto Overview
The specs in one line: 19% THC, <2% CBD, 7-9 weeks flowering, 500g/m2 reported. Best indoor or outdoor. easy grow.
Original Kush Seeds lists this at $30.61 — below the median of $35.64 across 5 listings. Pack options: 3-seed at $30.61, 5-seed at $44.99, plus larger sizes.
Smell-first: cut one of these buds and you get a clean, candy-sweet citrus note that doesn't lean piney or fuel-heavy the way a lot of autoflowers do. That comes straight from the 70/30 sativa-dominant makeup Original Kush Seeds built into this one—a deliberate departure from the indica-leaning side of their catalog. At 19% THC it hits with a clear-headed, functional lift rather than couch weight, which lines up with the genetics on paper.
From a practical standpoint, the numbers here are genuinely useful for planning: 500g/m² in a 7–9 week flower window is a solid return for a strain rated easy across both indoor and outdoor environments. You're not babysitting it through a difficult stretch phase or fighting slow maturation. Keep temps in the 70–80°F range, give it decent light, and it will mostly handle itself.
Best fit for first-time autoflower growers who want a daytime-leaning effect without a long grow cycle.
Genetics & Lineage

This sativa-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 Original Kush Seeds, 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 19%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.
THC Level & Potency
Grapefruit Auto delivers THC levels of 19%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.
Growing Grapefruit Auto
Grapefruit Auto is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.
Indoor Growing: Expect a flowering time of 7-9 weeks with yields of 500g/m2. Plants typically reach 60-100cm 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
Grapefruit Auto features a sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. 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, Grapefruit 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.
