The specs in one line: 20-25% THC, <1% CBD, 9-11 weeks flowering, 400-500g/m2 reported. Best indoor or outdoor. moderate grow.

Lineage: Quasar comes straight from Buddha Seed Bank out of Barcelona, a breeder with a long track record of producing sativas that actually finish on a reasonable schedule. At 9–11 weeks flowering and a potential 400–500g/m² indoors, it sits in a useful middle ground — productive enough to justify the run time, manageable enough that you're not babysitting a monster canopy all season. THC tests typically land in the 20–25% range, and the flavor profile stays firmly in diesel territory: sharp, fuel-forward, not particularly sweet.

Plants have a sativa stretch to them, so SCROG or early topping will keep things tidy indoors. Outdoors it handles well in warm climates, though the 9–11 week window means you'll want a site with a long enough fall. Difficulty is rated moderate — beginner-adjacent growers can manage it, but having a few runs under your belt will help you get the most from the yield potential.

Genetics & Lineage

Quasar traces its genetics to Quasar (Buddha Seed Bank). 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 Buddha Seed Bank, 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 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Quasar delivers THC levels of 20-25%, 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 Quasar

Quasar 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 9-11 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm 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

Quasar features a diesel terpene profile that develops complexity throughout the flowering cycle. Pungent fuel and chemical notes hit first, followed by an earthy, musky undertone. 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, Quasar 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 Quasar?

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.
