The shortest version: Original Kush Seeds's take on sativa genetics, 21% THC, 8-9 weeks flowering, moderate grow.

Original Kush Seeds lists this at $49.57 — the upper end of the comparison range (up to $38.93). Pack options: 3-seed at $49.57, 5-seed at $54.89, plus larger sizes.

Smell-first: crack a jar of these feminized seeds after a successful run and the sweet, almost candy-like grapefruit note hits before you even get close to the cure. That aroma carries straight through to smoke, which makes sense given the 70/30 sativa-dominant split in the genetics—this isn't a couch-locker, and the 21% THC reads more cerebral and clear-headed than the number alone might suggest.

For growers, the practical side holds up well. Flowering wraps in 8–9 weeks, indoor canopies average around 400g/m², and the plant handles both indoor and outdoor environments without demanding expert-level intervention—though calling it moderate difficulty means you'll want some training experience before you run it alongside easier strains. Stretch is real with the sativa lean, so top or LST early if ceiling height is a concern.

Best suited for daytime-focused growers who want a high-THC, sweet-tasting sativa that doesn't require a dedicated greenhouse setup to finish well.

Genetics & Lineage

Grapefruit traces its genetics to 70% Sativa/30% Indica (Original Kush Seeds). This sativa-dominant feminized 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 21%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Grapefruit delivers THC levels of 21%, 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

Grapefruit 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 8-9 weeks with yields of 400g/m2. Plants typically reach 60-100cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. 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 dense flower formations.

Flavor, Aroma & Terpene Profile

Grapefruit 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 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.

Who Should Grow Grapefruit?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
